I recently purchased a sc400 1uzfe pcm and attempted to put it in my 1993 sc300 both are the same years every pin matched the only thing that was different was the ignition signal from the cams sensors / distributors on the 1uz uses pins 5,6,7. 5 is for left bank 6 is for the right bank 7 is rpm signal after i installed it got a code 15 ignition signal and a code 78 fuel pump ecu which is disabled in my car with 12v mod my stock pcm never gave me code 78 which along with the failed injector drivers is why im changing out the pcm plus a nice little burn spot on the board so back on topic in theory you should be able to splice into pin 7 on the e10 connector on the pcm and jump it to pin 6 and 5 . from there the ignitor should take over and it should run ........ should not for the faint at heart and i dont know if im going to attempt this or not but we will see how desperate I get to drive my car pimp the ruckus till it rains

SO, can you use ECM #2 to repair ECM #1 since they are pretty much identical, or at least follow the trace and try it one more time with the jumper in place?
