it's solid Cel once key is on, as a fried ecu.. not datalogging working of course.. relay is going crazy  , i was thinking about wiring (stock) but once i plugged oem ecu everything sounds good... it's a EF OBD0 to OBD1.

Do you have an Ostrich? If so, try with a chip to see if you still have the problem.

Yes, right now im runing with D16z6 OBD1, i made my own distributor wiring harness, i think that's not the problem because as i said , tested with stock obd1 ecu and not cel...
