finally installed my SD2 chip today, figured i'd post some thoughts after about 75 miles of use. i'm an absolute tuning-rookie, i've done some tuning on sportbikes using the dynojet powercommander, but nothing on my car. i was using an as-delivered turbotweak alky chip with a 85mm maf and translator previously.
setup was very easy, only took about 2 hours to install (including welding a bung for my ats in my intercooler pipe and wiring my map 5 volt reference to the tps feed from the ecm) and 2 brief test drives to get a good baseline where it would run and idle well. had to add to the AE enrichment a couple times to clean up a tip in stumble, throttle response is great now! midrange fueling is incredibly smooth now, car pulls great from all boost and rpm. false knock ignore parameter is awesome, and i always wondered what my intake temps were post-intercooler... now i know- about 2 degrees above ambient at speed. no question i have a lot left to learn but i really dig the ability to adjust so much via my laptop. i still need to trim some WOT fuel so it blends better when the alky starts spraying, but so far i'm extremely satisfied and can't wait to make some hard pulls with it! also, the security function is brilliant too, kudos eric/bob!
