Eprom chip for 276 284

[Dave @nz]

Hi,
I am after an eprom chip for a 2.3 M3 bored to 94mm with Schruck 276-284 and running stock plenum and AFM.
Is there such a thing and where would I buy one from?

Trying to avoid going down the tuner route, not sure where I live if there is anyone with the know how to do it properly.

Thanks in advance.
Dave

Hi Dave,
As an alternative, you can change the stock DME ignition timing and air/fuel ratios both over a small range. There is access to the adjustment through a rubber plugged access hole at the back of the DME. The schedule is: full counter clockwise position, called 0 = stock; position 1= fuel + 3.9%; 2=+10%; 3=-3.9%; 4=0%,-3.1 degrees spark; 5=+3.9%,-3.1 degrees; 6=+10%,-3.1 degrees; 7= -3.9%,-3.1 degrees. So there are 8 settings in all; not the same as a custom chip program but it might be worth a try.

You need a triangular shaped tool to change the position, and I filed the end of a nail down to make one. You can see what it should look like in the rubber covered access hole at the back of the DME.

Dave:

Call Doug at Turner Motorsport. I'm quite sure they have a chip for that combination that would not require a dyno tweak.

Hi Ron & Larry,
Thanks for the ideas I have a few months until I am ready to turn the key, I will contact Turners first and then depending on how that goes adjust the fuel/ignition switch position.
I was thinking the camshafts are a common thing but don't see on web sites chips to go along with it other than full hog carbon inlet.

I accessed the computer and checked there is no Blue and Black plugs, looks like a US harness was installed and I will install these plugs soon just to add to the options.

Aren't chips from Luis still considered the "best" from what I'd heard?

[Dave @nz]

Do you have any more details on Lewis

PM me, I have Luis' contact info (IIgomotiv). He burned a chip for my 2.5L with A/N and it runs great. His track car is also pretty dang sweet.

Thanks Evan,
Pmd and now have two good leads, many thanks.
