I've just started working on a VZ Clubsport LS2, T42. Just got thrown by this error message which I've never seen before tuning with Flashscan. Going through the normal procedures > IGINTION ON > click READ CALIBRATION DATA > select T42 CONTROLLER > click CHECK STATUS (result OK) > click START.
Once Flashscan has completed reading the T42 and after the 15 seconds countdown has finished, this message appears:
Looking in EFILive tune screen you can see the checksum errors:
So I click on the UPDATE CHECKSUMS and get this lovely message:
I've read the PLEASE NOTE and sounds exactly right for my situation but not seeing this error before and not seeing any mention on the forum I thought I would post to ensure it's fine for me to UPDATE CHECKSUMS.
Cheers,
Brett
