Thomas, when they did the swift, they did use the rolling road loads to get the map right as non of the generic ones as you call them worked for my car, it was superchips that did it and it took them almost a full day to get it right. iv always used superchips and its never give me any hassle hence why id like to stick with a brand i trust ? is that such a issue ?
im no expert unlike you, im not really that bothered about been one either i just want a reliable 250 or HP as the car is a daily hack, not no track car etc
It's not an issue of brand, it's finding a person who will work with whatever the ECU is to put a map together generated from the best parameters to deliver the right balance of power economy and reliability, arguably needed more on a 'daily hack' than a track car, as you can spend a LOT of time mapping the part-throttle areas of the map, to get them right.
Superchips dealers generally deliver remaps for standard engines, not custom-built maps. When did you have the Swift mapped? It's possible that today's Superchips is a lot different to the outfit that spent a day working up a custom map for your Swift. Unless you know the person who's doing the mapping you're in danger of finding yourself sitting next to a bloke with a laptop who doesn't know his AFRs from his exhaust temps, but knows map A goes on engine code B, but is wearing a Superchips sweatshirt.
