[s-cars] RS2 ECU for sale

[Keith Maddock]

So it sounds like the only difference is probably just a resistor in the circuit between the micro and the output pin?
Does anyone have the details on what circuit modifications are necessary?

Also, do we know if the software logic/algorithm is essentially the same?
(Other than what I assume would be a "constant" or "trim" or "calibration" to match the MAF circuitry resistor)

Or does the RS2 software contain enhanced control algorithms?

95 968CS (Frankfurt DE nur bis 26.09!!)  mit 968 MAF

ADU Rs2 and AAN ecu's will work in either car, but you need native software
in either ECU, or the car won't run correctly.
Assuming matched hardware ( MAF/Injectors/FPR, etc):
>>>rs2 native software in AAN ecu== runs too rich
>>>AAN native software in ADU ecu == runs too lean.

ECU modifications in MAF circuit are necessary to run native rs2 software in
AAN and vica versa to  achieve proper A/F ratio.

I have heard from a couple of people off list that these are plug and play
interchangeable.
