I have a Katech LT1 mated to a T56 running the E92 using a 2015 Denalli ECM and OS. The engine starts and idles after a 3 wire to 4 wire high side fuel pressure sensor and harness swap, no codes currently present.
Issue I have is the VSS reads 158 all the time.
Question i have is what ECM and OS will work with the T56 running a 2 wire vss? We currently have the 2 wire VSS into pins 6 and 7 in connection 2, per the Denalli wiring diagram. I have tried various input and field changes withing the ECM. The harness appears to be a butchered factory harness, with that said all sensors are working and reading.
I assume that a OS change is needed along with possibly figuring out how to bring in a digital speed based on the camaro or vette wiring diagram.
Any input would be helpful
Thank You
