The Eurocharged map is specifically designed and written for the car in question.
The MSL map is very similar, though generic for all the M156 engines. It can however be tweaked for a specific application or modification.
Agree..... And Disagree.....
The Eurocharged map in not necessarily written for the car in question, as most are downloaded with a generic map based on the specification of the car and through experience gained from previously identically modified cars, it is not necessarily live mapped to tweek it to your specific car.
The MSL Map appears to be the same, based on previous experience with identically modified cars.
They are only specific to your car if they are live mapped.
Having said that, for most peoples cars having something like a secondary decat, aftermarket filters, the map (Eurocharged or MSL) is going to be pretty much spot on, without venturing into any areas of risk to the engine (Too much advanced timing, running close to a lean AFR).
At MSL for instance, after the map is downloaded it is ran up on the rolling road where items such as the AFR (Air to fuel ratio) are checked, make sure it is within the safe parameters, but not necessarily adjusted.
Feel free to correct me if I'm wrong.
