Hi Todd. That's interesting to know... I did actually originally speak to GMG about helping figure out this install, and they told me it would be new R&D for them, and weren't quite sure what would work right away, and what would need to be tried out first. I may give them another call. Thanks! I think the issue with Softronic stemmed from the fact that all communication went through an intermediary, as opposed to Scott directly. There may have been some facts that were lost in translation.

I love to see that people are working on this swap! =) I do wonder if he has a software package ready to program, or is just giving the '04 996 DME programming a try with the 997 motor? The latter seems to be the case.
-
Yup, looks like you are correct. I've heard back from both FVD and Softronic on this issue, and neither will sell their conversion files for this particular conversion. It's a little odd, since Softronic sells many other conversion files for a reasonable price (almost double the price of a simple ECU tune), but won't do it on this particular conversion. It seams it would be fairly difficult to pull off the install on one's own, without the ability (or knowledge of how) to write the correct M97 engine control maps into the stock 996 ECU?
-
That's great news... Thanks very much for the reply! Unfortunately, I'm not sure who can sell the correct software. I can't get a clear response from Softronic as to what "conversion file" they sell is the appropriate one to use for a 3.8 installed in a 996 3.6 chassis, and FVD refuses to sell their 3.8 -> 3.6 software anymore, insisting that they will only do the conversion in house.
-
Thanks for the reply! From what I could find, the last engine swap Todd had posted about was the 3.6 X51 that went into his boxster. The work he did to integrate that properly, including the upgrade to a full DME 7.8 system was impressive! What I can't tell however, is if putting an M97 3.8 motor in the 996 which already uses the 7.8 DME, can be done w/o replacing the wiring looms. It seems like a "simple" software program of the engine control is all that would be needed, but I don't know. Hopefully someone who's done it might be able to share. Thanks!

First, please let me apologize to those who will ask me to search... I've done no work for a while now and have just searched and read continuously! =) But, I'm down to the wire now. I must make a decision on what engine to replace in my 2002 996 by tomorrow. I'd love to put the 3.8 X51 motor in it if there is a good electronic solution that allows all original systems to function correctly. Otherwise, I'll have to use a standard 996 X51 replacement motor. Tough, I know. =) I know a few people have put the 3.8 X51 into their 996's... I was wondering if it can be done with the stock 2002+ 7.8 DME, and stock wiring harness, with something like a softronic software reprogram... Also wondering how much additional hardware would need replacing, in the form of control modules, sensors, etc... Or, physically, is it only a matter of merging some mismatched hoses? Again, thanks in advance to anyone who can help answer these questions! I promise to keep searching in the mean time. =)

I just had to buy a new radiator, due to the beginnings of a failure. This picture is really out of focus, but the white stuff on the top corner of the radiator is corrosion from coolant seepage. Not enough to drip, but enough to drop the coolant level in the resevoir, and a sign of future trouble.

Trouble with GT2 wheels in a TT (C4S) front wheel well.
itacud replied to itacud's topic in 996 TT, 996 TT S, 996 GT2
I had wondered about that... but the wheels did fit just fine on the previous owners' Turbo and GT2. I also had my allignment checked, and nothing unusual was found. -
Trouble with GT2 wheels in a TT (C4S) front wheel well.
itacud replied to itacud's topic in 996 TT, 996 TT S, 996 GT2
Sorry for the ommision... The Wheels are BBS E88's, in (supposedly) stock GT2 sizing - 8.5x18 ET 40 front, and 12x18 ET 45 rear. Tires are the recommended GT2 fitment Michelin PS2s, in 235/40/18 (N2) front, and 315/30/18 (N2) rear. Thanks! -
I'm finding that BBS wheels in a GT2 size/offset are unable to fit in my C4S fender well - they rub - actually push the forward fender liner when turning to full lock. (Especially where the radiator bulge is.) As it's quite common for Turbo owners to use GT2 wheels, I was wondering if anyone else found their radiators were getting in the way - through the fender liner? Here's a very bad photo illustrating the problem: To address this, the shop is trying to move the radiator forward slightly, but that's introducing a whole can of worms with fitting the ducts/bumpers/etc - and I really don't want cooling airflow and/or aerodynamic airflow to be adversely affected. But, this seems a very odd problem, since the front wheel wells should be the same between the C4S/Turbo/GT2. The forward fender liner clearance issue is very puzzling. Any insite from you all would be greatly appreciated!

Giahan, if you're looking for an AWD dyno location in the south bay area, Streetwerke in Palo Alto is an excellent shop that works on german cars. As a lot of their customers are Audi quattro owners, they do have an AWD dyno: http://www.streetwerke.com/dyno.html Maybe a few people could get together and schedule some time on their dyno, with some sort of a discount.

Hi, I'm hoping to install a set of PSS9's on my (new to me) 996 C4S this weekend. It appears that height adjustment is the only solution to a couple of issues that turned up during a recent alignment inspection. I usually replace the suspensions on my cars myself, then go back to the shop for the final height setting, alignment, and corner weighting. I've searched all over the forums looking for detailed pics/tips about the install, but can't seem to come up with very much detail. I'm sure I just don't know where to look, or how to use the search properly. I did find a few web-photographs of a PSS9 install on a 996 C2, but not quite enough to get a sense for the best procedure to follow. Also, and probably most importantly, I'd really like to know the correct torque values of all bolts & nuts that may be undone or loosened in the process, as well as pointers to any nuts or parts that may need replacement, once removed. I suppose a technical service manual would have most of the required information, but a complete manual is quite expensive! If any kind souls on this forum happen to have the information, a pointer to a DIY, or have done the project themselves, I would be very grateful for your knowledge! :) Thanks!
