DET ECU & MAF PART NUMBERS
BRUJACK I believe your first set of numbers maybee incorrect.

These are the part numbers for the BLUEBIRD ECU.
(NOTE: REMEMBER THERE IS A DIFFERENCE BETWEEN AT & MT)

U12 SR20DET AT 4WD/AWD 23710-79E10
U12 SR20DET MT 4WD/AWD 23710-79E01

Here is the part number for the Pulsar GTI-R ECU.
(NOTE: PULSAR GTI-R ONLY CAME 4WD/AWD NO WORRIES HERE)

RNN14 SR20DET MT 4WD/AWD 23710-54C00

Here is the part number for Pulsar GTI-R MAF SENSOR

RNN14 SR20DET M/T 4WD/AWD 22680-54C00

I talked to Ben at JWT and the following numbers are for a Bluebird DET ECU:

23710 79E00
A11-000 E50

There is also a large IO at the top of the sticker. The other numbers that I posted were for a GTi-R ECU.

BRUJACK try this site it list a whole bunch of ECU part numbers.

Well either Ben at JWT is wrong or the info in the spreadsheet is not complete, or there is another part number. The engine had a 4 wheel drive manual tranny attached to it. I am guessing that there is another part number.

The spreadsheet has good info on it though. Thanks for the link.

Can I use a AT ECU with an MT ?

I don't believe that you can. I had JWT reprogram a DE ECU for my car. I will send them my ECU and the DET ECU. Call JWT to verify that a AT will work for a MT car.

Is that the number for an AT or MT ???

I believe that it came out of a MT car, but I am not sure, as the importer was confused as to which ECU went with which engine. That is why I called JWT to verify.
