flash counters
gentlemen you are indeed correct and also incorrect
the citroen ds3 1.6 thp uses a Bosche MED17.4 ECU
this ecu has a flash counter that will count the number of times that data has been written to the ecu
if your remapper has decent eqipment and has paid the full licence agreement with the equipment company then it will automatically reset the flash counter to teh previously stored count number once the file has been written
this is certainly the case with a KESS V2 which is my favoured tool of choice at present primarily because of vehicle coverage and
because of the flash counter resetter
I also have cmd - which is a very expensive option to have the flash reset software added to it - mine does not have this option
this has been tested as a ds3 1.6 thp that i have remapped had to go back to citroen on an unrelated warantee issue
so to be on the safe side we wrote the ecu back to standard
citroen did indeed interrogate the ecu as is now standard for them on any warantee claim and they came back with no reason to believe the car had been mapped previously - they attended to the problem and added some software upgrades and then once back I mapped it again (free of charge to the customer)
The conclusion can only be - use a reputable company - ask if their tool has a flash counter reset option ( automatic like kess or manual like cmd s on certain models) if you use a tuner that charges £200 for a remap my guess is that they will not have that option
Flashremapping are a Viezu approved dealer - 23 years experience of tuning cars - underwritten insurance - 7 day money back guarantee - lifetime warantee on tuning maps - we always use the latest TUV approved tools - advice is free - remaps from £299
