Reinstalling a tune vs disconnecting the battery
Is there a difference between re-installing a tune you already have vs. disconnecting the battery to reset the ECU? Are there benefits to resetting the ECU by disconnecting the battery vs reinstalling an existing tune.
For ex. If my RPMs are a little erratic and I reinstall my tune and the problem still exists can resetting the ECU by disconnecting the battery correct the issue?
The tune has been in use for a while with no issues but the RPM issue began after switching back from an 87 tune to a 93 tune.
