R33 Auto Ecu

[dangerman4]

Yea yea we have heard it all before, however... just a simple question...

I have been led to believe that when setting up any aftermarket ecu eg wolf, power fc, etc they will give you grief with gear changes..

But has any one tried leaving the standard computer in control of the auto and other car functions and wiring in the aftermarket ecu to control timing, fuel and boost etc.. basically running the engine from the wolf and the trans and car from the standard ecu.. i believe this can be done just by getting another ecu loom plug from the wreckers and cutting out the wires not needed... any thoughts?

Yes, a heap of people have tryed wiring over the top of the original harness. The problem is that in order for a proper change the ignition must be cut back a certain degree as a sort of torque reduction operation. Now if you could use the output of any one of the torque solenoids as input into a computer that was able to retard timing a certain amont then it would be able to be done. How well it would work is unknown and I only now of one computer that could do it.
