How many times can I tune?

[13blacksho]

I've searched a bit on the forum with no luck...

My car has been to the dealer a few times this month with the PTU and RDU situation.
So my tune has been loaded and back to stock what feels like a LOT!
Is there any problem with changing the tune often? If so what would be safe?

No problem, the PCM might not finish relearning in between, or behave as awesomely as you expect if intervals are short. So it requires forgiveness/understanding on your part.

I'd definitely avoid multiple rewrites best I could, but should be fairly sturdy. Worst comes to worst, you can have the PCM repaired at CircuitMedic.

It depends on the tuner. For example, the SCT devices typically are locked after 100 writes.

Thank you!
I has been six times in the last 7 days... Not sure if that is too many but it feels like it.
