Alright, we installed an apexi turbo timer on my friends wrx this morning. Everything went well and it was a perfect install and everythign works perfectly except for one small fucntion. The air/fuel ratio part of it only works when you turn on the headlights. We spliced the wires into b17 and b19 in the ecu, which is what it said to do. Everythign else works, but if his lights are off, it reads 20.0. any ideas on what is wrong?

 

no.

ask on www.i-club.com

and let me know what you find b/c I install mine next week ! haha

 

well if iwere u jsut remove the wire and wire it directtly in to the signal wire before it connectes to the ecu...

 

Ok, tell me this. He called me a bit ago and told me that he turned on his high beams and the check engine light came on and now won't go off. lol.

 

lol
u fucked something up idd u rad the wiring diagrams upside down and mirrored the wiring diagrams for the ecu.....

 

Just splice them onto a constant 12v source. Headlights are only running the volts through when turned on.

 

Someone read the diagram wrong...

tapped into the wrong wire/wires...


It happens, Just check everything over.
