Hondata

are there any identifying marks on the serial number that would tell someone if they have a stage 2 or 3??

my friend has a system he got from tom payn, but wasn't too inquisitive when he got everything installed (he had an engine built and tom just talked him into a hondata as well at the same time.)

so we know that he doesn't have datalogging, but it is possible that he has a stage 3... any hints?

Look at the serial number. s2nn-xxx s3nn-xxx

cool. thank you
