Hey everyone, I'm trying to put this 2003 evo8 ecu into my 2g dsm..

I've got all the pins swapped around, but I can't get ecuflash to read from the ecu. The first thing I noticed is that the check engine light DOES NOT come on when I put the key to on. Is it supposed to?

When I go to read the ROM off the ECU, this is what happens.

sending init sequence 1 (0001)
sending init sequence 1 (0003)
sending init sequence 1 (FFFF)
sending init sequence 1 (F0F0)
no response to any known code

As you can see I tried the unlocker to no avail. I cut the connector off the reflash wire, and put a pin on it then plugged it into pin 79 on the ecu. I checked it for continuity, it's good, jumps to 12.4-12.5 volts on each init attempt, then falls to 4.5v.

I need to get into the ECU to disable the imobilizer so I can start the car atleast, but I can't even talk to the ECU. Does anyone have any idea what the problem might be? Or can at least tell me if the CEL is supposed to come on in the EVO8 when the key is in the on position (with the engine off)? Thanks for any help...

-will

check obd plug wiring ,and yes eng light is supposed to come on ,stay on for a few secs then go off .

try this
relocate pin1 on obd to pin 9 on obd port
obd pin 4+5 to gnd
obd pin 7 to pin 62 ecu
obd pin 9 to pin 56 ecu
obd pin16 to pin 25 ecu 12v sw supply

Thanks for that...you wouldn't happen to have a diagram for which pin is which on the obd2 connector, would you? I can't seem to find one.

viewed from pin side

Thank you so much for the diagram...I haven't gotten around to rewiring it yet, or testing the ecu for that matter, but I'll let you know how it goes..

do please
