Removing my battery and my UpRev tune.
 

Quick question guys. Removing the battery from my Z for a long period of time wont affect my UpRev tune correct? The Z is going into hibernation tomorrow and I want to remove the battery since she wont be started for a few months. I e-mailed UpRev but they never wrote me back. Thanks Guys.

Nope -- won't affect it. It should be flashed to the ECU.

I was pretty sure of that, I just wanted to hear from some of you guys to be sure.

The only thing it will do is clear fuel trims and any other data NOT flashed to ROM, which may affect how it runs at first (not necessarily in a perceptable way, BTW), but so long as major changes were flashed to ROM, it will be right as rain after driving around for a bit.

It's just gonna be like an ECU reset. The new uprev maps will remain but the learned fuel settings will be erased and learned once you drive it again. You won't even feel it.

Yep. My battery was out for an extended period and no issues.
