No, re-mapping only really works with Turbo charged engines. It is no rocket science, the added power comes almost entirely from higher boost pressure so not likely to make much difference to your N/A Rex.
What makes me laugh are the claims of earlier boost (lower boost threshold- a function of physical turbo matching), and the wild % increase that you hear for power and torque and fuel economy. And just when I thought I had heard everything, I now hear that mapping can drop your revs by 2-300rpm at a steady speed. Wow, I think the bosses of messrs Alonso, Hamilton, Button, etc would be very keen to get in touch with these engine management geniuses.
Re-mapping works well, and a ECU re-flash is the best way to do it, much better than those plug in boxes that intercept and fool the ECU into doing something different, plus as a business it is the most lucrative, as once you have cracked the manufacturers coded maps cells, you can map one vehicle and forever more cut and paste that map into hundreds of same engine vehicles. Charge £400-600 a pop for 30 minutes work, which involving no replacing of parts. A proverbial gold mine.
I say crack the code, but most of the goons out there buy the cracked code from a 3rd parties in the first place, as they aren't bright enough to figure it out themselves.
Once you have the capability to do all this, all you have to do is convince potential customers that it is not detectable (absolutely incorrect on any ECU that I know of), and that you don't have to worry about the warranty being void.
The added bonus is you can re-charge the same customers when MB (for example) re-flash the ECU with their latest maps, which happens from time to time during regular servicing, which wipes the re-map.
Now, where is my OBD cable and my laptop
