I did a search, but I came up empty..

I am FINALLY getting my act in gear and building my test bench. My questions is with the 7730 ECM which VSS connection on the ECM do I use? I am guessing it is Pin BC6 (bigger black connector C6) instead of BB9 (VSS Low) and BB10 (VSS Hi) I will be running AXCN Code from my 91 Vette ECM.

Mainly to test out Scannor Pro with the 7730 and a Corvette CCM as the older TunerPro ALDL did not work well with shutting up the CCM.

So that was my only main question for the wiring..

THANKS

 

It depends upon your application. The stock AXCN code will use the magnetic VSS inputs (Lo & Hi). However, with an '89 converted to SD you may be using the optical input and flipped the VSS input select bit in AXCN.

Either one will work with the proper input selected in the BIN. Best bet is to match it to the application so the test bench BIN matches the car BIN.

I am running all 91 gear so it will be the OEM, I did not flip the bit.. THANKS!!

Now to get my hands on a 7730 for the bench..
