M3 is just better ian...like it or not, proven time and time again...I mean 3.8 vs stock M3 and still no give.
Lance, you don't know Cape Town very well do you… My GTV is still a 3.2 and will hold it's own against an E46 SMG M3. And Rush's brother's car (3.7L GTV) rips M3's apart at the seams. Even e90 M3's…
Sorry for jacking my own thread!
I'd say chip is less safe than a (good) remap, as the chip can only work with the information it is given from the sensors that it plugs into which are very limited - in fact not sure what one would use on a n/a car? - throttle position +...?
Phil, a remap is as good as the guy installing the map. What it does is essentially the same as a chip, but just digitally. A chip will alter readings from MAP, MAF, O2, etc. sensors to allow the ECU to calculate new values for ignition timing, fuelling and throttle position. The fact that it runs on the stock ECU means it still incorporates all safety features built in, like limp modes, power restrictions for cold engines, reactions to knock sensors, lean mixtures and overfueling etc. Modern day "chips" in SA are more like additional ECU's (SA engineered Dastek Uni-Q for example) and they can interrogate any signal and feed it to the car's ECU and even make a signal up to feed the ECU, and even rpm sensor signals to alter timing, variable valve timing to alter operation for greater power instead of economy, etc.
When someone remaps your engine, they wipe the original map clean and train your car to do stuff that it's not designed to. So the management system may not react the way it's supposed to when things go wrong. This could lead to engine damage over the long run as your car very often gets taught what the dyno operator thinks are the right figures for fuel mixture, knock reaction, etc.
For that reason I would prefer to have a chip fitted than a remap.
