Looking for a quick bit of direction. I finally have the time to install Jay's original chip in my car in place of the Autothority one to see if the knocking can be stopped. Behind the footwell carpet is a wooden panel that, when removed, exposes a metal plate. Above the plate is a little compartment. Does anyone have a picture they could e-mail to me to show me EXACTLY where the computer is? Do I remove the plate or is it above it? I don't want to mess this up. Also, does the computer need to be taken out or can it be opened up while still in place to simply swap the chips?



Thanks

you have to remove the plate - it is held by 2 phillips screws and 2 plastic screws



on the back side of it is a box (the bigger one of the stuff back there) - remove the box by removing its 3 screws



carefully bend back the tabs to remove the lid - these will only bend a couple of times without breakng, so i don't recommend bending them bac in place each time you do this - i instead run a loop of electrical tape around the entire assembly



there you will find the chip under the plastic retainer - remove the retainer and then carefuly lift the chip out



note the position of the nitch on the chip



be very careful when installing the new chip to insure that every one of the pins is in a hole before pushing down

There was a procedure to swap chips in the 968 in the May 2006 issue of Excellence magazine. <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" /> It has pictures and step-by-step text explaining how to do this. You will have to take the computer module out of the car to get at the tabs that hold the lid onto the module's chassis.

Bob- I haven't that copy (it is really hard to find Excellence around here in Rubber Boot, Nova Scotia). Do you have a .pdf version of the article? The pictures would really help. I was planning to do this on Tuesday evening but, if it is risky, I just might take it to the Porsche dealer to do. You don't really want me to bend Jay's pins, now, do you?

Kim, I certainly don't want you to bend Jay's pins!



I don't have a PDF of the Excellence article, so I have no easy way to get it to you. I also couldn't open the PDF document in the link that flash left -- it was all gibberish when it opened.



Swapping the chips is not hard and it takes just a couple of screwdrivers (phillips and flat-blade) and a pair of needlenose pliers. The hardest part is getting the ECM module out from its location under the passenger's feet. Once you've done that, the rest takes about 10 minutes. Send me a note to pvreditor@yahoo.com and I'll send you the Word document of the text of the article. That and very big pictures are all I have.

until the bug gets fixed, you have to use explorer to download and open files



i agree, it is a very simple process really - you will need an 8mm wrench for the nuts that hold the ECU to the plate



getting the plate out of there is a twisting motion - be patient - it will come out of there

I just changed my chip and most of the process is easy. The hard part on my car was trying to get the carpet pulled away from the foot board after a PO used thick, tough, sticky glue to hold the carpet in place <img src="/forum/images/smilies/968/mad.gif" class="smilie" alt="" /> I did like the results after putting in the chip <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />



Cheers,

Stephen

I hope that I will like the results, too, although I am doing it backward (ie installing original chip and removing aftermarket chip).

Well, I have decided to admit defeat and have the dealer do this. The PO, consistent with most of the other issues that I have had to address, seems to have butchered this (when the aftermarket chip was installed)and pushed the plate that holds the ECU in without using very many screws and, in the process, has 1) knocked off all the fastening clips for reattachment (now it is wiggling and is probably the source of at least one of the rattles in the front right that I have been noticing) and 2) covered up a bunch of wires that have been cut off that I think are part of the original stereo wiring. Given that I don't have any feel for what exactly is attached to the back of that plate nor do I know how whatever is there is attached into the wiring system I think it best to get this done correctly. I don't want to break off a bunch of 14 year old plastic clips. 75% relative humidity, 28C and trying to work in a small area doing something that I don't even know what it is does NOT help my MOOD any!!!



I am going the get Jay's chip installed, the plate re-attached properly with whatever number of screws it needs and then evaluate it. Given that I have put about $21K into this car since I bought it in Sept 2004 (not including buying it) I think that a $100 or so to not screw this up is money well spent.



If this solves my knocking problem I will either want to a) try to see if one of you has an original chip (second version) for sale or will need to see if Pete thinks that an RS Barn Stage I chip will be OK.



I will update as soon as possible. Getting frustrated, but making progress all the while. Life's been good to me so far.

Kim,



If you decide to stay original just leave my chip in, we'll work something out.



Stay in touch,



Jay

Kim, don't feel that you're alone! I don't remember exactly when it was, but I stopped adding everything up when I went over $15K (besides the purchase price), and that was more than a dollar or two ago. My wife thinks my 968 is the equivalent of the "$6 million man". Lucky for me, she doesn't know the whole story, and there's still a large "smile factor".

Archorman - you got that right! Mum's the word! But I really like this car even better than the blue cab (am I a nut?). Yeah, it's rougher, noisier, bumpier, lower and more work to drive - but those are just a few of things that I like better! It's also faster, edgier, stickier and racier. I also learn more about 968s with this car. How about that.

Stephen,



I did not use the glue! It must have been guy before me. I never even tried to remove the carpet.



Have a nice day!

Well. well, well.



On Thursday I had the ground points cleaned. We found 7 of 10. Could not find number 7, 9, or 10. Looked like maybe 9 and 10 are related to RHD cars(??). Anyway, cleaning up the ground points stabilised the voltmeter (it often jumped around a lot for no reason that I could ever see, having the cab of the same year did provide something for reference), stopped the squealing of the alternator when the A/C was on, smoothed out the idle and STOPPED THE KNOCKING!



I am going to test everything on the weekend to be absolutely sure but, if all is well, problem may be found and solved. Jay, I will have your chip in the mail to you on Tuesday if everything checks out. It was never out of the box so the pins didn't get bent (haha).



Hoping for the best but planning for the worst.
