Fuel injected 2 step?

Tim Lisson · 02-28-2012, 02:55 PM

I'm going to try a 2 step with my car this year. One thing with my set up, the O2 sensor reads nothing at my preferred starting line RPM due to its location and with my crossmember, I can not add a collector extesion to help the situation. I did try 2 stepping one time and it was so overfueled it barely stayed running, then left like a slug. For foot braking it likes more fuel in those cells. I will pull a bunch of fuel out of those cells when I try it this spring.

Ed, you posted sometime ago regarding percentage of AFR change, equaled? What was that again?
