Originally posted by ner947 With the exact same MSQ, it ran leaner. I checked everything... Watched the realtime display, recorded a datalog and watched the big picture, probed various voltages with my scope, etc. I was stumped. I had to increase my required fuel from 8.2ms to 9.8ms to get the idle AFR back to normal. My idle PW's went from 2.3ms to 2.7ms. I hooked up spark and fan control, everything works up to peak boost but I didn't expect that I would need to tweak my required fuel like that.
Well in a way that starts to make sense for me, since I now run the 460cc injectors, and my req fuel is like 8.6ms. The msq i got from you Nate, was way too lean for some reason? My idle PW are almost the same as yours too..wierd...The fuel side is running just great now though with a little tweaking 15 psi duty cycles are in the 60-70% range too. One more thing i noticed about your msq Nate, under the codbase options, you have "msnSpark" selected, WITH the "neon/420A" selected also. As far as I know, you are only supposed to have the neon code selected. I have no clue as to what having both of those selected would do either..
