So my RSA does not have air conditioning and not much of a LWF induced stalling problem so I'm in need of two (preferably with stock motors) USA based owners to help with testing before I start duplicating eproms for everyone. I'm looking for a MY89 or MY90 having a DME control unit with 911 part number and a MY91+ having a DME control unit with a 964 part number. You also need to have AC. If interested please contact me with a PM and once I find two people I will delete this thread.

Thanks,
--jason

PM sent!

Edit... I think I need to check to see if I have the 911 part number... Where and how do I check that?

PM sent from a 93 C2 owner! We got em covered Smokin!

My 90 has a 964 part number and 95 993 intakes and MAF with something done to the chip I am guessing. Have the stalling with a 7.5 lbs flywheel so I am hoping you can help me also....pleaseeeeeeee

Chris M.

Oh well. 92 here.

If you look under your drivers seat you will see the DME control unit and at very front on the top of the case there should be a purple (color could be different?) sticker with the Porsche part number. You don't need to remove the control unit from under the seat to see the sticker.

I have a 91 with a 964 part number. I'd be more than happy to help you out, Jason.

At present I don't have a stock chip; if that matters (except yours, of course).

Cheers,
Dave

Mine shows a green sticker and reads the following

Bosch
0 261 200 450

911.618.124.01

TYP 911 MW-DZ-01

All 964 DMEs are basically the same except for the EPROM, i.e. some have the
fuel quality switch & others don't but not an issue. Thus, most/all 964 owners
with a LWF should be able to help Jason do the evaluation.

Check here for the typical 964 Bosch DME part numbers which
can be used for the evaluation:

Loren, the voice of P-car knowledge has arrived! Jason, are you in NW CT or in MA? I'm 45 minutes away and other than 8/17 on (3 days at Summit point) i'll be around.. The 964 will be at Limerock on 8/26 for some "cleaning out" but will be a street car for a month afterwards..

Re: our conversation via PM my part # is 911.618.124.01. According to 'the good book' that's from an 89.

This will be a great contribution by Jason in solving the LWF idle undershoot
problem (stalling) by either re-writing the u-P code for the dynamic 964 idle
system or by increasing the injector turn-on point, i.e. > ~ 1100 - 1300 RPMs.

My sill plate shows a manufacture date of January 9th, 1990...

Jason,
My 90 C2 has the 911.618.124.01 DME with the LWF + Andial "weight". I don't have a stalling problem, but if you want to try a chip in it, it's okay with me. (oh yeah, and it has AC)

I'm Aug. 92.
