I am having a tough time trying to sort out the tune after my MS3 install. It seems like everytime I change something that helps then the next change I make hurts. I have the idle sorted out for the most part(iac down into the 70-80 range at idle), but when I go to drive it and log afr error w\ the wideband it bucks and stutters in low rpm and is way down on power in mid rpm. Any way if anyone has a working tune for hpt please help. I am way off ve wise and any baseline would work. When you search the bin files for ms3 -nothing.

Thanks

ok... what problems are you having?

I have figured out the ve table and the idle is pretty good. Know I need to get the buck worked out @1600rpm. I think I will mess with the throttle cracker for that. Then also I am about 32 degrees advance in he
the idle table to get stable and I don't really know what to do with the rest of the table it looks like crap. Also I am tunig for 14.2 afr at idle and part throttle and am not sure if thats the best thing to do.
