Just a FYI for the newer members.
The base tune numbers on what CAN BE SEEN by TuneEcu or TuneBoy shows no difference's between them.
Insider information says there is stuff that can't be seen. True, tunes are not happy going between some Tiger and Speed Triple ECU's.
Have a early ECU I did load a S3 tune and proved the gent's ecu was the issue. He fried it, tried it on a newer ECU and it would not allow the offending tune to be loaded.
For most of us, it's the detonation or pinging that's the issue damaging piston's. That sucks.
So for peace of mind, back up your tune. Then play, do suggest notes with set conditions or it will be a WAG.
