Changing Corrado Spoiler Activation Speeds ========================================== Quick summary by Jan Vandenbrande You can fairly easily (and cheaply) change the spoiler activation speed on your Corrados. The US versions of these cars activate at 45 mph which means that the spoiler goes up and down virtually all the time between lights. The higher activation speed therefore saves wear and tear. The change involves desoldering a resistor, and swapping it with one with a lower value. This archive explains in fairly good detail how to perform this opperation. Also see: http://www-cad.eecs.berkeley.edu/~jimy/corrado/spoiler/ for a VR6 specific archive with pictures. GREAT JOB. Caveats: ------- o So far I have not found any consistency in the resistor values used by VW, nor what value you need to get it up at another speed (as you will see below). Use the values listed below as merely the range you should be looking at, and probably the *easiest* is to buy trimmer (small potentiometer) and adjust the value to the desired speed. o If you do not have a desoldering iron, buy a desoldering wick to suck most of the solder away.

Jan, feel free to add to your page/FAQ.. First you need to find the spoiler control module. It's NOT a relay in/above the fuse box. There is a module about twice the width of a relay mounted to the dashboard on the driver's side. The easiest way to find it is just to trace the wiring from the spoiler switch. It goes directly to the module, which is about a foot away. The module slides off the metal mount. Go ahead and do so. Next, you'll need to take apart this module. The connector side has a plastic cover that comes off with some prying. Now the circuit board slides right out. What you are interested in is a pair of resistors towards the top of the circuit board, as illustrated: this resistor | |-------------|----------------------| | ---- X o O [ ] [] | X=transistor | ---- [] o- [v ] | | ---- [ ] [w ] O | o = resistor | ---- [v ] O | | [] [ ] [w ] | [], O =capacitor | [ 4 ] | | [] [ 0 ] ===== ===== | [ ] | [ 0 ] | | | | | [ ] = chips | [ 1 ] |R1 | |R2 | | [ ] | ===== ===== | | -diode- | R1,R2=relays \___________________________________/ | {} | | | | {} | | | connector side, component side up Simply put, it's the topmost resistor not counting the group of 4 on the left side. Its value is 590 Kohm, 1% tolerance(!). Replacing this resistor with a lower value will raise the speed at which the spoiler rises. After some experimentation, I found that a 220k resistor will increase the raise speed to about 67 mi/h (110 km/h), as well as the lowering speed to 35 mi/h. I'm guessing that by changing the resistor directly below you can change the lowering speed independently. I didn't bother, since I got exactly what I wanted with the one change. The 220k resistor is commonly available, even at radio shack. Just as a side note, these two resistors are the only two that appear to be hand soldered on the board, and the only two with 1% tolerance... maybe someone in Europe with too much time on their hands could find out what values are used over there. You could also send $75 to AMS and have them solder in the 10c resistor for you.

People who wish to select their spoiler activation speed may find this information rather useful, and I really believe that the predicted outcome will closely reflect actual results. Jan, if you want to also add this portion under the FAQ, feel free. Here's what I did: I took the measured resistance of the OEM resistor (the 45mph one) - 618k ohms And, the measured resistance of the 67mph resistor - 221k ohms All resistances where measured with a Fluke 87 DMM I then set up a linear regression equation using my trusty scientific calculator. This is what I came up with: MPH = 79.25 + (Resistance)(-5.5416 x 10E-5) or Resistance = 1430045.45 + (MPH)(-18045.45) If you look at the top formula, you will see that the maximum activation speed can only be approximately 79.25 MPH (substitute a zero for resistance - short circuit). I made a chart of theoretical activation speeds @ various resistances: MPH Resistance 45 618k Popular resistor sizes and speeds 50 528k 470k - 53.2 MPH 55 438k 390k - 57.6 MPH 60 347k 330k - 61.0 MPH 65 257k 270k - 64.3 MPH 67 221k 220k - 67.0 MPH 70 167k 180k - 69.3 MPH 75 77k 150k - 70.9 MPH 79.25 0 120k - 72.6 MPH 100k - 73.7 MPH 82k - 74.7 MPH 68k - 75.5 MPH Matt H. 90' G60 From corrado-l-owner@teleport.com Wed Oct 25 18:32 PDT 1995 Date: Wed, 25 Oct 1995 21:25:58 -0400 From: MHeff82156@aol.com Subject: Re: How to change spoiler activation speed Sender: owner-corrado-l@teleport.com To: corrado-l@teleport.com Reply-To: corrado-l@teleport.com Message-Id: <951025212335_54453546@emout04.mail.aol.com> X-Envelope-To: JAN@FSHPP1 Content-Transfer-Encoding: 7BIT Precedence: bulk Status: RO In a message dated 95-10-24 19:36:16 EDT, you write: >Simply put, it's the topmost resistor not counting the group of 4 on the left >side.

I got the Fluke DMM and the soldering iron out as soon as I read this. I also used a 220k resistor, and got the exact same results. It only took like 15 mins. (including crawling under the dash) to perform the modification, and the resistor only cost $0.07. I was about to shell out the $75 (plus shipping to and from) to get the AMS module, because everyone was telling me that was the only way it could be done. I figured it could be done, or AMS wouldn't make you send them your OEM module. After all, why would they want the thing if they couldn't do anything with it anyway. It's a real scam that AMS charges $75 to do this, it's such a piece of cake mod. to perform!! Plus, it will reduce the wear on my spoiler motor. No more up-and-down's between those damned traffic lights. Matt H. 90' G60 From corrado-l-owner@teleport.com Thu Oct 26 06:20 PDT 1995 Date: Thu, 26 Oct 1995 08:27:00 -0400 From: "Dennis J.

The reason the spoiler went up immediately is because of this infinite resistance you created (infinity > 618k). This means that you're 92' module works on the same principle as the 90' module - The spoiler activation speed is inversely proportional to the module resistance you choose. In plain English, as the module resistance increases the spoiler activation speed decreases (as is you're case) and as the module resistance decreases the spoiler activation speed increases. I did post them before, but here's the results I got from my 90' module: MPH = 79.25 + (Resistance)(-5.5416 x 10E-5) or Resistance = 1430045.45 + (MPH)(-18045.45) If you look at the top formula, you will see that the maximum activation speed can only be approximately 79.25 MPH (substitute a zero for resistance - short circuit). I made a chart of theoretical activation speeds @ various resistances: MPH Resistance 45 618k 50 528k 55 438k 60 347k 65 257k 67 221k 70 167k 75 77k 79.25 0 As you can see from the chart, as the resistance increases the spoiler speed decreases. This is why you're spoiler goes up immediately.

If it was real hard to read I'll repost it. The circuit that the resistor is installed in is a simple voltage divider. There is an op-amp (or CDA) very close to these resistors. So it is my guess that these two resistors set up the reference point for this circuit. This circuit is probably a Schmitt Trigger or some other sort of op-amp voltage comparator. It's most likely a Schmitt Trigger, since an upper trip point (raise the spoiler) and a lower trip point (lower the spoiler) are necessary. If this is the case, it shouldn't really matter how low of a resistance you substitute for this particular resistor. AMS probably just replaces the resistor with a short, since they do advertise that their module raises the activation speed to 80mph (the theoretical limit). Is there anyone on the list who has the AMS module and can confirm this? It would be quite easy to wire the module so that it is adjustable. This is what I would do: 1. I would remove the relay from it's casing, and then proceed to drill two small holes (or one) into the top of the case for the wires to enter the module. Leave some slack (not too much that it gets caught up in the relays) and tie a knot in the wires so they don't pull out of the printed circuit board once soldered in place. 2. Remove the resistor and solder the wires into its location on the board. Thread the wires through the hole(s) you put in the module (knots inside the case) and pop the module back together, then run the wires to the location where you would like the adjustment control. 3. Go to Radio Shack or your favorite electronic supply store, and purchase a 500k potentiometer and 68-100k resistor (if your worried about shorting something out). I'd buy a 5, 10 or 15-turn potentiometer, otherwise the adjustment will be very sensitive. 4. I'd probably mount the adjustment control right under the dash just to the right of the fuse panel cover for two reasons. It is probably the most convenient location to make on-the-fly adjustments, and the wiring run is very short (cuts down on noise) and requires no fishing or major dissassembly. 5. Drill a hole the size of the pot's threaded portion of the shaft in this location or where ever you decide to place the control. Do not mount the pot yet, making the connections will be easier if you wait to mount it. 6. Solder one end of the resistor you purchased to one of the wires, and then solder the other end of the resistor to one of the outermost terminals of the potentiometer. The potentiometer is actually going to be used as a rheostat (variable resistor) so only two of the three terminals will be used. Take the wire that remains and solder it to the center terminal of the pot. 7. Insulate connections with heat shrink tubing or electrical tape. If you use heat shrink tubing, which I would, remember to slide the piece of tubing back over the wire before the connections are soldered. Otherwise, you won't be able to put it on. 8. Now mount the control and road test it. Don't get in an accident while you're watching for your spoiler to rise :-) I like the results I've gotten by putting the 220k resistor in (raises at 67mph and lowers at 37mph). I also noticed that the speed at which the spoiler lowers increases by the same amount as the activation speed. For example, if you put a 180k resistor in and get an activation speed of 69.3 MPH the speed at which the spoiler lowers will be 69.3 - 45 + 15 or 39.3 MPH.

I'm trying to figure out if it's possible to put somekind of variable resistor on the box, and label notches on the side to change it anytime you want to any speed. That would be cool. As a side note, do people think it's a good idea to forward this mod to European Car? It would be interesting to see if they put it in an issue.

Its value is 590 Kohm, 1% tolerance(!). I think we all know now that this resistor value is for pre-92 Corrados. And for 92 and later, there is Jim Young's procedure at http://www-cad.eecs.berkeley.edu/~jimy/corrado/spoiler.html (which is a pretty cool WWW page, if you ask me). To summarize what Jim says: His stock resistor was 33 kohms, he replaced it with a 10 kohm, and now his spoiler rises at 55 MPH. I modified my spoiler activation speed over the weekend. But my 92 SLC had a 51.7 kohm stock resistor, which I replaced with a 2.0 kohm resistor. Now my spoiler rises at about 66 MPH. It used to go up at 46 MPH. So not all 92 & later Corrados have the same resistor configuration. But the circuit board looked exactly like the picture on Jim's page. (Which is a really cool page. Did I mention that already?!) Just another spoiler activation speed data point. Dennis J.

Crawl under your dash and remove the cover to gain access to the fuse box. Shine a flashlight up through this area toward where the manual spoiler switch is located and locate the back of the spoiler switch. The wiring from this switch leads right to the spoiler module. Get the resistors at any electronic supply store (i.e. Radio Shack). I don't even know if the dealer would have it (you only need one). >I've seen ads for a module that makes the spoiler rise at 75-80 mph for >about $75 exchange. Is this the same thing??? These resistors you speak of >would cost $0.50/pop at RS. Maybe 15 min. total to solder. So at $45/hr >(the going shop rate...) we're talking $11.75 + tax to achieve the same result. You only need to replace one resistor. I'm assuming they want $0.50 for a 3-pack? Ask them if you can purchase a single resistor, and use the chart to select that resistance based on the speed you want to have the spoiler rise at (you should be able to buy a single 1/4 watt resistor for approx. $0.12). >>MPH = 79.25 + (Resistance)(-5.5416 x 10E-5) or >>Resistance = 1430045.45 + (MPH)(-18045.45) > >How did you come up with these formulas? I used the linear regression (LR) mode on my scientific calculator to get these formulas. The linear regression mode of a calculator basically draws a linear graph in the calculator's memory and allows you see any point along that straight line graph in its memory. As you know, to draw a straight line you first need two points. These points were determined by the resistances and the activation speeds @ those resistances. The first point to use is the factory setting, which is an activation speed of 45mph at a resistance of 618k Ohms (according to Fluke 87 DMM). The second point is the modified point, which is an activation speed of 67mph at a resistance of 221k Ohms. Now, that's all we need to figure out every point in between (you can do this same thing with a piece of graph paper - although, it is not near as precise). The formulas can be re-written as follows if they confuse you: MPH = 79.25 - (Resistance)(0.000055416) Resistance = 1430045.45 - (MPH)(18045.45) >Specifically, what does the -5.5416 x 10E-5, 1430045.45, and -18045.45 represent? When you do a linear regression equation you produce a constant term (A) and a regression coefficient (B), which fit into the following formula: y= A + Bx - where y is one of the variables (MPH) and x is the other variable (Resistance), or vice versa. I did the equation for each way, solving for both resistance as well as MPH. So, in the MPH formula: 79.25 is the constant term; -0.000055416 (or -5.5416 x 10E-5, in scientific notation) is the regression coefficient. In the Resistance formula: 1430045.45 is the constant term; -18045.45 is the regression coefficient. Here is an example of how to use the formulas: Let's say you want to have your spoiler rise at 70mph and you don't know what resistance you need to accomplish this. Here's where the formulas come in handy. We will use the resistance folmula to solve this particular scenario. Resistance = 1430045.45 - (MPH)(18045.45) Resistance = 1430045.45 - ( 70 )(18045.45) Resistance = 1430045.45 - 1263181.5 Resistance = 166863.95 ohms or 167k ohms (same as value on chart) Now, let's try it the other way around. Let's say you found a 150k ohm resistor laying around, and you were wondering what activation speed it would produce if you installed it. We would use the MPH formula for this scenario. MPH = 79.25 - (Resistance)(0.000055416) MPH = 79.25 - ( 150,000 )(0.000055416) MPH = 79.25 - 8.3124 MPH = 70.9 mph >>If you look at the top formula, you will see that the maximum activation >>speed can only be approximately 79.25 MPH (substitute a zero for resistance >- >>short circuit). > >Wouldn't this short lead to other problems in the relay circuit? The circuit that the resistor is installed in is a simple voltage divider. There is an op-amp (or CDA) very close to these resistors. So it is my guess that these two resistors set up the reference point or trip point for this circuit. This circuit is probably a Schmitt Trigger or some other sort of op-amp voltage comparator. It's most likely a Schmitt Trigger, since an upper trip point (raise the spoiler) and a lower trip point (lower the spoiler) are necessary. If this is the case, it shouldn't really matter how low of a resistance you substitute for this particular resistor. AMS probably just replaces the resistor with a short, since they do advertise that their module raises the activation speed to 80mph (the theoretical limit). Is there anyone on the list who has the AMS module (or has replaced their resistor with a short) and can confirm this?

Due to continued domino effect, I ended up under my dash and figured I may as well change my spoiler activation speed as some of you bright and industrious people figured out how to do. This is the table that was published for the G60s: PH Resistance 45 618k Popular resistor sizes and speeds 50 528k 470k - 53.2 MPH 55 438k 390k - 57.6 MPH 60 347k 330k - 61.0 MPH 65 257k 270k - 64.3 MPH but in the text it also states that: "Simply put, it's the topmost resistor not counting the group of 4 on the left side. Its value is 590 Kohm, 1% tolerance(!). Replacing this resistor with a lower value will raise the speed at which the spoiler rises." The resistor is indeed 590 kOhm, and measured about that... So oddly enough, the starting value above is 618k... I think the Ohm meter must have been off by a bit. I had not noticed that difference so, I installed two 220k resistors in series (in the hope to get the spoilers up at 55) but instead it goes up at exactly 50 mph. Hmmmm. I guess, Jan's revised table, looks something like (no computers were used, so you are in *grave* danger of inaccuracy): 45 590k 50 440k (2 220k in series) 55 290k populare value: 270k Have not tried the latter as yet.

I replaced it with a 10.2k ('cause that's what I had lying around) and the spoiler now goes up at about 60 mph. My aim is 55 but I am getting tired of squirming underneath the dash so I may just leave it. Now I am really puzzled why all these spoiler activation boxes have different valued resistors (I am sure what was reported was correct). I guess the moral of the story is, buy a 0-50 kOhm trimmer (a potentiometer you adjust with a screwdriver) and go from there. -- o ___|___ [\\] | Jan Vandenbrande jan@ug.eds.com __0 /\0/ /-------\ _ | http://alicudi.usc.edu:80/~jan/ \<,_ O \\ (_________) .#/_\_. | "Aerodynamics are for people who (_)/ (_) // [_] [_] |_(_)_| | cannot build engines" - Enzo Ferrari From owner-corrado-l@teleport.com Mon Mar 11 12:30 PST 1996 Received: from mailer by fshpp1 with SMTP (1.38.193.4/16.2) id AA01180; Mon, 11 Mar 1996 12:30:14 -0800 Return-Path: Received: from desiree.teleport.com by UG.EDS.COM (PMDF V4.3-10 #4) id <01I27NO8JMUO003WK1@UG.EDS.COM>; Mon, 11 Mar 1996 12:28:59 -0700 (PDT) Received: from localhost (daemon@localhost) by desiree.teleport.com (8.6.12/8.6.9) with SMTP id MAA11493; Mon, 11 Mar 1996 12:25:40 -0800 Received: by desiree.teleport.com (bulk_mailer v1.3); Mon, 11 Mar 1996 12:25:38 -0800 Received: (from daemon@localhost) by desiree.teleport.com (8.6.12/8.6.9) id MAA11444 for corrado-l-outgoing; Mon, 11 Mar 1996 12:25:35 -0800 Received: from kzsu.Stanford.EDU (KZSU.Stanford.EDU [36.118.0.90]) by desiree.teleport.com (8.6.12/8.6.9) with ESMTP id MAA11386 for ; Mon, 11 Mar 1996 12:25:27 -0800 Received: (from airvent@localhost) by kzsu.Stanford.EDU (8.7.3/8.6.9) id MAA28134 for corrado-l@teleport.com; Mon, 11 Mar 1996 12:25:12 -0800 (PST) Date: Mon, 11 Mar 1996 12:25:11 -0800 (PST) From: bdp Subject: More Spoiler Speed Things Sender: owner-corrado-l@teleport.com To: corrado-l@teleport.com (Corrado List) Reply-To: bdp Message-Id: <199603112025.MAA28134@kzsu.Stanford.EDU> X-Envelope-To: JAN@FSHPP1 Mime-Version: 1.0 X-Mailer: ELM [version 2.4 PL25] Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Precedence: bulk Status: RO Well, while we're getting back on the subject: I changed the spoiler activation speed on my `92 SLC, but not with the expected result. I didn't measure the resistance of the one I pulled, but I first replaced it with a 2.2k ohm resistor. This resistor caused the spoiler to go up at 55, down between 15-20. Not satisfied (I want it up at 65), I took the resitor out completely and put just a wire in its place. Result: exactly the same as the 2.2k ohm reisitor. Up at 55, won around 20. My module looked a bit different than the one on the web page, so I thought maybe it was different for the `92 SLC's. Well, not quite. Last night Kevin Peterson (no relation, other than a good name and C color..) and I tried to change the activation of the spoiler in his `93 C. Wed did the same procedure as I did for my car. And got the same results. And his module looked exactly like mine. Maybe my monitor's resolution is poor, or maybe I read teh ASCII diagram incorrectly, but our modules didn't seem to look like either of those on the web. I'll see if I can get a photo of mine and get it up on my web page. Oh well, 55 is much better than 45... Brian Peterson airvent@kzsu.stanford.edu http://kzsu.stanford.edu/~airvent/ "On they come.

I checked the meter with several other resistors, and what I measured matched the color code on the resistor every time.

I originally had the 33kohm resistor in the module (exactly like on Jim Young's Corrado page) and pulled it out and installed a 0-50kohm potentiometer. When either I turn the pot all the way down or short it completely the spoiler will come up at 55mph. This is a small improvement over the stock 45mph, but I was hoping I could make it come up at around 65 or 70mph. There is another resistor on the circuit board nearby the one we all change. Has anyone else had these results and managed to do anything about them?? At what speed do the spoilers on the Euro Corrados come up? _________________________________________________________________ ariff@primenet.com asidi@ucsd.edu carpe diem ariff@deltanet.com vrsix@aol.com '92 SLC (corrado-l member)
