I have a turbo back exhaust and recently put on a header and a week or two later my check engine light came on. So I put on a wire CEL fix device. It has been about four days since I installed it. I was just wondering how long I should expect for my check engine light to turn off? Or is there something else I should use?

 

Have you diconnect the negative at the battery after you installed the CEL fix? You have to disconnect the negative side of the battery for at least 15 to 30 minutes to reset the ECU. The check engine light should go out. Make sure that after you have disconnedt the NEG. turn on everything headlight, radio, ignition and etc., the reason is that you want to drain the power completely gone so that the ECU can be reset.

 

so should i disconnect both the positive and negitive posts or just the negitive?

 

i disconnected only the positive post right after i installed it and a few days after, and it is still on, but that was only the positive

 

I know this is a little expensive, but you might want to look into the AccessPort from COBB tuning. With this and the street tuner software that you can get for it, you can pretty much set anything you want, including any CEL fix you may need. Check out the instructions for this on the COBB website. Expensive, but worth it! Once it's out for the 2.5RS, I'm getting one. Until then, I can only imagine the potential.
