Karthik, that's what I meant!! I know u guys build the maps from scratch, buuut, don't u think it would be beneficial if u could read the map and THEN alter the values? (rather than trial & error from the start) I'm asking because I know a division in my company that uses these map scanners. Do u think they would help u?
what are Piggy Back Chips ?? how much do they cost ??
SD, piggy back chips are chips/modules that latch onto your existing ECU (hence the name) to read and alter the existing maps for ignition, fuel timings, etc. The problem with them is, you have to get ones that are compatible with your car's ECU or are at least retunable, otherwise it's a big waste of money. Expect to pay between Rs. 20k and 40k for a basic to mid-range solution, in India as well as imported. Pete's Performance has a few in stock for a few cars here....
