Trying to troubleshoot this ecu swap. I’ve done the pin swaps and car will start but won’t hold an idle. I can pedal it and keep it running but once I stop it dies. It is giving mil for camshaft/crankshaft (sorry I don’t remember them off head). I’ve swapped back to the Evo IV ecu with wiring back to stock and it fine. Everything I’ve seen shows both sensors are the same and the picks ups are also. I’ve connected pin 40 to 92 (sensor grounds) and 40 to a direct ground on the ecu side. I’ve also grounded 91 directly to chassis. Immo is disabled.
Thanks

Update. We’ve tested the wiring. The cam is getting 5v and crank is getting 12v. They both have ground thru harness to ecu pins and chassis ground. The signal will have to be probed unless evo scan will cover it (that’s a Monday job).
is the Evo 8 ecu more sensitive then the 4? If disconnect the cam sensor it doesn’t affect it a bit. Like I said the 4 ecu doesn’t have any cel and runs fine. The 8 has cam/crank faults. Wiring per fsm on evo 8 is correct and like said checked all 6 wires directly from sensor to ecu.

 

Move Evo 4 pin 6 to Evo 8 pin 53
Move Evo 4 pin 8 to Evo 8 pin 22
Move Evo 4 pin 20 to Evo 8 pin 32
Move Evo 4 pin 21 to Evo 8 pin 34
Move Evo 4 pin 22 to Evo 8 pin 8
Disconnect pin 40 cut and attach to pin 92 ecu side
Disconnect pin 87

 

Ok so it was the camshaft cylinder. Modified the evo 4 to look close enough to 7-9 and it starts with no mil. No on to maf scaling issues.
