I have a tune that I run where the "Limp Home Fuel Limit" (B0732) is set to 120 mm3 for anything above 2000 RPM. My question is, my fuel pressure table doesn't go to 120mm3, so what happens? Also when the truck goes into "Limp Home" mode, what does the ECM use to determine fuel pressure?

Thanks

Thanks Nick.

Any idea of why the desired fuel pressure would go from 175 MPA to about 140MPA when the limp home fuel mode is turned on? I can't see anywhere in EFILIVE that is commanding the desired to drop from 175 to 140.

Thanks
