Does anyone know how to dampen the effect of fuel trims so my car does not hunt (surge) from fuel trims adjusting. I have no problem in open loop. Thanks in advance..
The trims are oscillating like they should but are over shooting there mark (I think). Have a look at my log A/F are fine. The surge goes away when I put it in open loop. I was thinking of adjusting the closed loop proportional or closed loop integrator delay. I think the position of my 02's may be causing this. Im running difilippo headers.
