air fuel is about impossible to get right at idle. Idle your egt's will be low, probably wont even hardly register. I saw 1350 once for a split second on a climb, let off and checked my piston. Some people run it at 1275 or so but keep in mind that 1350 and your almost guaranteed meltage. These sleds run hot midrange, well mine does with speedwerks, but keep your egts around 1150 to 1220. make sure the map you are trying out is from a sled that has the same color injectors and ecu (ecu will have a O or a Triangle etc.) I played with base maps from and found that with their air fuel targets they were pulling like 25 and 30 precent fuel from my bottom end which scared me so i fattened her up. It knew where to add and take fuel from a few places that I would have never figured out such as right before power valve opening at 62 rpm.īottom line is there should be some good maps coming out since pcv been out a while. Same result.Īutotune was good though for modifying midrange. You could adjust fuel map yourself but a/f gives a little more consistency. I end up modifying my air fuel ratio map (im using autotune) and that gets my egt's down automatically. Not to say that the a/f is not a valuable secondary tuning instrument, The problem I have with the air fuel guage is that I have no idea what my targets should be? Idle seems to be like 13.8, 2% throttle 14.5 or so. I bought a air fuel guage for my m1000 as well as egt's and i find the egt's WAY more useful.
