question.. You tuned my car on the dyno last summer. I recently put in a test pipe and was delayed in getting the non fouler in so i got a check engine light.

I bought this http://www.actron.com/product_detail.php?pid=16350 product. I just want to make sure that if i use this to clear any codes that i will not in anyway effect the tune on my car.

 

you are right that will just check the code and clear them it will not have anything to do with your tune on the ecu.

 

thanks!
