You may also be able to figure out what connections need to be made to fool the ECU into thinking it's getting a shift signal from an automatic transmission. Then install a rotary switch on the dash to set to whatever gear you're using 
.
I guess that could work except you would have to change the rotary switch every time you shifted. Haha. Maybe use that just to troubleshoot my issue?
I have read using the 3rz auto engine/ecm with a manual trans is impossible to fool, per the 3rz post on here. And with that logic, I assumed it was impossible to fool a 5vzfe ecm. I could be wrong though. I haven’t spliced a ecm loom myself yet.
