CEL on during a tune. No faults stored...

While dyno tuning, sporadicly the CEL will come on. Try to check the faults and it has 0 faults stored. I tried checking fualts the old fashion way looping the check conector over by the ecu. Nothing. Continued tuning to 560whp no problems besides this CEL.

as of right now we have 2 things working against us. M&W is about a foot away from the ecu, and we are running a non resistor plug.

Today i will be moving the m&w into the engine bay, and swapping in some iridium resistor plugs. Hopefully this will help.

But normally when CEL/MIL is on and no faults stored, doesnt that mean bad ecu ????

S300 wont datalog with engine running

Didnt get around to moving the ignition box yet, but did swap in iridium resistor plugs. No more CEL, drove the car around for about an hour with 0 issues.


Still can't datalog though. I made a seperate thread for that :(
