ECM non bird or cat info.

Trying to make a 90 F150 with a modified 5.0 and a standard trans mass air. Using a newer truck auto ecm with a auto trans. I pretty much got the harness part figured out, I keep reading about putting resistors inputs to the ecm to trick the computer to think it has an auto trans. I can't seem to find more info on it. So if anybody has info or where to look can  you let me know.    The ecm is a "HUG2"  5.0, 4R70W trans.

You may be able to have a tuning shop do that for you. If they have the software for that ECU they can change the value of TRLOAD and TSTRAT and burn a chip for you. Im not to well versed in ECU crossovers but Im wondering if one of the mustang ones would work I believe the cbaza strategy with the T4M0 ECU is 94-95 Mustang 5.0 with manual trans.

Good info here in the "write ups" tab
