I've never heard of someone having an extra ECU for tunes and it actually seems like a great idea. This seems like the best move. Not sure what an ECU costs but I know it's less than an engine |
I have been tuning 911 Turbos since 2001, always had the original ECU copied to spare, the tune the spare. I have a 22 on order and plan on doing the same. |
Why doesn't everyone do this? The other guy said it won't stop the logging in other components though like the transmission. Is that accurate?
