Ive driven a powerfc, hondata, autronic, uberdata and piggybacked turbo honda. All have driven basically the same. My best advice, pick a tuner and then grab whatever ecu he is comfortable with. Dont take shortcuts..

re launch, antilag (2-3step etc): i find these features very handy for a street driven fwd car. allows for presicse launches and safe, fast shifts. Datalogging, well is an advanced fault/tuneing feature to allow precise mapping and power delivery. When DynoDave tuned my car with hondata s200, we used the auto-tuning features and my wideband o2 to get all partial throttle maps spot on during street tuning. The result was a precise lambda in cruise, allowing 4-500km's a tank with 170kw atw. Oh, and this was fulltime open loop!
