Hello everyone I just got my 08 G37s tuned a few weeks back and I just had a few questions if I were to get a check engine light and clear the code with my OBD fusion app or have to disconnect the battery for a while to work on my car I won't lose my tune right? Thanks everyone hope it's not a stupid question I just don't want to flush money down the toilet!

Should be fine. The maps are programmed into the ECU it's not a piggyback type of product.

 

Thank you!
