Ive finally got to run my car with the WB in it using the hitmans map 4 720s 3bar map. At idle and light crusing the AFR was 11.3:1. When hiting the gas as soon as I get into boost it goes to 13-14:1 and I let off right away. I leaned out the idle AFR to 13.3:1 and it idles very well. Then I richend the maps from right before the secondaries come on to about 15psi (im only running 8psi now). I went out and drove the car this way and its at about 11:1 right before coming on boost then as soon as I get on boost it goes to about 12:1 then bucks and starts to go leaner. What could be causing this? The secondaries are set to come on at the first sign of boost. It only goes lean as soon as I hit boost 0-1psi and up. I was thinking that it could be 1 the secondaries are not coming on or 2 when they come on the fuel pump can not keep up and there is a big dip in the fuel pressure causing it to buck and go lean. What do you guys think? I am having one more problem with the car https://www.rx7club.com/forum/showth...hreadid=116616 but I dont think this would affect the tuning.
