Hi Guys,

Up untill now I have never tuned a car myself, just used the flashscan V2 and efi live software to do data logging etc, and send those files over to a tuner who did the tuning for me.

I do however get the question very often if I cant turn of the check engine light in cars that have only had an exhaust upgrade. To me that sounds like a simple adjustment, but I don't know.

How would I be able to do this myself?

Thanks in advance
