Re: DIY "chipping" of your alfa - KWP2000 plus
Dont be daft - would you wipe your PC and load on a pikey CD you got off the web?
You dont know what you are writing to your ECU and what impact it will have, reputable tuners, whether they buy in or develop their own maps, extensively research, test and guarantee their remaps.
If your car is worth £500.00 go ahead!
The JTS is hard to remap because of the way it works, normally aspirated remaps rely on advancing the ignition and altering fuelling to suit pre-detonation.
The JTS' primary way of working though is to increase fuel pressure to a calculation based on air volumes and ignition plays catch up.
Because of this, you can supercharge or turbocharge the JTS without a remap, more air in = more fuel pressure and it just keeps on going.....
