Hey all, I recently installed the Labree Resonated Test Pipes on my 08 Nismo and while it was a pain in the *** to do just by myself, I got it all done in about 2.5 hours. As soon as I started the car, my CEL light was on. Nonetheless, the pipes came with 2 CEL bung extenders to fool the cel. The cel still came on. What can I do for this? I have the UPREV osiris tune, from when I had my kinetix hfc's--if I reset the ECU will this erase my UPREV data? Would NOT want this to happen. Should I add another 02 extender to each test pipe? (I have 2 extras.) The sound is great. If no solution is given, should I get my car retuned, so that the codes can be turned off? Would appreciate any input!

 

I would say 1. try resetting the ecu 2. contact uprev sense they probably take out the string of code for the cel light to go on.

 

You disconnected the battery before messing with the sensors correct?

 

I thought labree test pipes weren't suppose to throw CEL's. Weren't these one of the better test pipes.

 

No I didnt because I had been told a few times not to disconnect the battery when the ecu has been tuned. Should I disconnect the battery overnight? I will do this, as long as I don't jeopardize my UPREV software

 

lol its a test pipe, get used to it and get over it
