a few weeks ago i was at the track and my ecu blew (still trying to figure it out) and I replaced it with an ecu from a 98 gsx (my car is a 97gst). Since then my settings are completely different. With the orginal ecu my lo settings were around -9 across and now they start at -16 at 1000rpm and going into -18 by 3000 and back into -16 by 4000. Why would the car be so rich that i would have to lean it out that much? Also its been acting weird since the new ecu. I keep on getting error code for P1400 with is the manifold pressure something and vent emissions control. Is there a difference between 97 and 98 emissions? The car drove great until the mishap at the track. Plus the car feels sluggish. I havn't tried to tune the hi settings yet, but when i get on it has like no power. I tried the other day to tune it- started with -10 across and the egts reached 900c by like 4000 rpm so i guess i'm running really rich at the moment and this is only at 13psi. The only info i've found on differences in the awd and fwd ecu is gearing. Will that make a difference in my afc settings? Thanks
