Paul's 330i

Petrol mate, in terms of actual HP 0 because I've only touched the throttle (pedal) map as its really easy to change but does make a huge difference, so far.. Can change literally any map on the ECU, but need a wideband ideally, logging data at the minimum. Can all be done diy though. Can even change it so the ECU only reads lambda of bank 1, then you can put a wideband in bank 2 in the spare hole. Not huge gains to be made power wise up top, but can gain up to 15hp across the midrange by tweaking vanos, disa and timing and fueling to match. If you dont mind losing the immo/ews then you can even have launch control. Only need a laptop, inpa cable, tuner pro (free)
