173 vs. 524 ECU

[Kondour]

If E30's had their own computer for the trannies, don't you think places like Dinan would sell tranny chips like they do for E36's?

My point exactley.

It will have a seperate control unit for the tranny. The 524 ECU will run any 325i just fine.

Dinan and other companies don't make a tranny chip for it because there is no market for it. Of all automatic E30s, how many had the electronic transmission? Less than 10%; whereas all E36 autos are electronic control.
