Anybody ever figure out how too? My truck hazes and stinks at idle but if I use the DVT to turn it up it is completely gone. Rob has it commanding 45mpa but it won't budge past 30mpa. I am on the newest version of EFI too.

Can't do it, tables do not work properly. Same goes for MAX rail pressure, put whatever you want in the tune but desired WILL NOT go above 180MPA.

Sucks too.cause it completely goes away if it is raised. Timing helps it too. Guess I will be shelling out some cash for new injectors. I just can't hardly deal with it anymore

Are you still running 40% over?.......I have a complete set of 100% overs from Exergy that I'm going to try and get installed this week if I have time.

I'm in the same boat, about to make the move to LA too. Can't get RP to stay above 5k at idle. Hazes slightly.

Since the fuel pressure base tables do not raise rail pressure at idle, you have to add rail pressure another way. Go to {B1076} "Fuel Pressure, ECT multiplier, Low Altitude" and set it to 1 in all cells. Now you can go to {B1056} "Fuel Pressure ECT, Low Altitude" and add or subtract rail pressure. The rest of the table will need to be modified or you will pull rail pressure when not desired, and have other problems.
