I have chrome in a obd2 ecu if any good
crome is like the vhs of programmable ecu's. You'd be better with hondata or neptune imo. I only know of one tuner close to me who would map crome and tbh theres a lot of bad press surrounding him and the life span of the cars he maps.
I think most of us north of the border know who I'm talking about mate. But as I've said before I've never used him personally so can't comment from experience.
