Possumlink v1/2 wrx Technical drawings / diagrams

Recommended Posts

Hi I’m wondering if anyone could help me with a diagram / the technical drawings for a possumlink for v1/2 wrx please, ecu has been repaired before so not wanting to tip more money into it but rather have a go at making it keep running the car for awhile. 

 

ecu has constant power out on ignition drives and seems to have a pulse with a noid light but not actually fire the coils or injectors but has its normal one click fire that possumlink does when key comes on.

 

even if anyone on the picture could point to what runs the ignition on them on the board.

If you have no injection or spark then it sounds more like you have a trigger issue.  Do you have valid RPM in the software or on the hand controller when you are cranking?

Yep, it shows 1-200rpm cranking, tps voltage works etc. 

And pulses a noid light just not the injectors or coils.

 

coils and injectors both had power, car was running on a g4 plugin previously. 
 

 

it’s like it’s keeping signal to the coils open cause the coils get hot and the signal shows a constant 12v

The biggest issue these suffered from was bad earths. Check for any burnt tracks on the PCB or solder joint issues.

Often fresh earths were run from the ECU to the block to sort issues back in the day.
