Just curious: could a good mapper work on any car, or is the experience model or marque-specific?

An engine is an engine, anyone worth their salt could work on anything, BUT, someone with particular experience will get to the same result much faster, and hence are likely to be cheaper in the long run...... i'd say it's 75% skill, 25% experience.

Simple answer, no

You need the right software for the type of ecu being remapped.

There are then specific features of the software within the ecu, which you must be familar with in order the map the engine correctly.

Many ecu types have immobiliser and other security features built in, which may need to be removed or bypassed in order to map the engine.
Particularly so with 2010 and future cars, which have features to stop engine mapping, or alert the dealer than its been altered, thus invalidating the warranty.

You can just "buy" all that stuff!! If you buy say a BDM interface kit from one of the aftermarket support people you can just specify what models you want to work on, and they will sell you the "checksum" correction programs and everything you need to be able to modifiy the ROM..... And as most of the world now revolves around 3 or 4 types of EMS, there is plenty of knowelege / info availible for anyone who wants to find out whick maps to change. As mentioned in my first post, it'll just be quicker for someone who already knows what to change and how!

Did say my answer was a simple one wink

Anyone can learn the skills needed, but not on my car thanks !

Bad mapping can kill an engine, so I'd recommend punters finds the most experrienced mapper they can, for the particular engine/ecu combo in question - be it stage 1 generic mapping, or stage 3 custom mapping

Their are some serious cowboys out there who'll claim they can map anything, screw your engine, take your money and run.
