 Re: ecu remap
It's unlikely that Vauxhall will bother looking for a remap. Once there's a switch in place then it becomes blindingly obvious. Some tuners are careless, too and overwrite the entire code block with a generic one. This will stand out. A good tuner will download the std map for your car, modify the necessary parameters and then upload again, thereby preserving all serial numbers and vehicle specific data etc.
Some ECUs have a non-resetable flash counter which is incremental and could give things away. Also if the dealer overwrites with new code as the commonly do to rectify known bugs then your remap will be lost.
Most dealers will not grass you up however - what's the benefit to them in stopping the manufacturer paying for warranty work?
Stranger still - some makers, notably Skoda, endorse remapped cars and allow dealers to sell new vehicles with a custom map in place! |
