EFILive's first VGT "Software Wastegate Tune"
From what I have scanned, the truck commands between 10-15 mm3 of fuel during idle. By changing the fuel to 25 mm3, it will "idle" higher.
As to what to exactly change, I am not sure, would have to play with it, or have Josh post a screen shot (...wink wink ...)
Josh, you have the right idea. What I have found to work is to set all cells in the zero pedal position row in "pedal position to desired torque" to 185 from the left side up to desired rpm then in "torque based fuel" the upper left corner must be filled in down to 185 and over to desired rpm with about 27 for it to work in colder temperatures. If it works when warm but not when cold raise the torque number our the fuel quantity. Remember in the lmm to do all pedal position to desired torque tables. Maybe bballer can chime in if I'm making this more difficult than it needs to be, this scenario works for me but I call him the lbz guru as he has an excellent understanding of how this ecm uses the data we input
Also I have had NO stalling issues and have done this on dozens of trucks
I set the vanes to all the way closed to help put a load on the engine so that it will warm up faster this will also make it whistle more however the increased idle speed is enough for it to warm up
Can't wait to try this on mine, have to wait until Thanksgiving when I finally get my LBZ! Wouldn't mind a warm up tune. What RPM is safe to high idle on? With a remote start, is it bad to have it high idle right away to say 1200 rpm?
