As for dealers detecting my remap, it's not an issue: when they plug into the port, their computer will just detect an 'anomally' and reset the entire system. The anomally could be an electric window going up and down too slowly or 65hp too much, the computer doesn't analyse the whys & wherefores, it just resets everything.
That's not strictly true...they will know the controller/ECU the fault is thrown up on, and depending on the error, can make a fairl good guess.
For example, you don't get 'Charge pressure limit exceeded' errors up on a std car!
You then reset the errors on an individual controller...not a blanket reset.
If they suspect, all they have to do is drive it...then they'll know...and if they want proof, they log the readings on the MAP sensor...anything above standard and bye-bye warranty.
But, they need to have reason, as most Techs are so pushed for time during servicing/repair work, they aren't looking too hard!
This, is the reason that things like the Superchips Bluefin is a clever idea...you swap the standard map back in for servicing/warranty work...so if they drive it, or log the MAP sensor values, it shows standard.
Not that I would condone this sort of behaviour, of course.
