Hi, been slowly trying to finish my 7MGE/auto to 1JZ/R154 swap in my supra but i ran into a problem, I dont know what my ecu is. I have been told it may be a chaser ECU or maybe a auto JZA70 ECU. I had my harness converted for a 5spd ecu by tweakd performance and it does plug into the harness but the ecu is missing the flying lead. Someone spray painted the cover so i cant read the part number. Just wondering if anyone might know what it is and if I can use it. Heres some pics

No you can not use it. Start looking for another ECU (OEM or Standalone).

That's not a soarer or chaser ECU. This is a soarer/chaser ecu.

thanks guys i appreciate the help. so consensus seems to be its an auto JZA70 ecu and it should work. still dont understand how it will run without the tps though

I'd say GE ecu. The flying lead has a small hump in the case which yours doesn't have. It will not work.
