Yeah I've had a go with alpha-n and hybrid alpha-n, found it good at higher throttle but at low speed low throttle i find it a bit problematic as ever so slight difference in TPS meant quite large changes in air. This is cos the throttle bodies are pertty big. MAP was ok when I'd sorted a stable signal, although had almost opposite problems with resolution at higher throttle positions - difference in MAP was very slight for big difference in amount of air going in. So eventually I settled for MAF, which is working ok for me. Its been a while since I've tried with alpha-n, so maybe I should have another go, seeing as I feel a bit more competent now.
You're probably right about EGT and some det cans, I haven't used either so far, just mapped fuel off the wideband, and sparks referenced from a standard S50B32 map and the standard M42 map, and obviously knocking the timing back off a few degrees from where det occurs. Any information on what exactly you ran and tips on mapping and how to map would be gratefully received, I'm still a newbie to this and hungry for advice. Are you a megasquirt user?
