I can't figure out this weird cruise surge issue. This is on a manual transmission truck and the surging only shows up around 1600-2300 rpm with cruise on. Remove the cruise from service and truck acts normal.
I have tried smoothing the Flow vs current tables, the pedal to fuel tables, and pulse table and I can't get it right. I have searched through this forum and it seems a few others have experienced it.
This is a CSP5 truck but I am only using tune #1.
Thanks for any help!!
