Hi guys i'm knew to efi live forum. i've got a 2001 4x4 p/u truck with a custom operating sys. 2 bar in it and have been working with it for a couple
of month now when i'm not at work. It's been alot of work starting from scratch. the truck was a 496 allison to begin with and has evolved into a twin turbo 604 cu truck. my problem is that something in the programming is pulling 4-6 deg of timing that is not on any of the timing maps that i can tell.
right now i have zeroed out all the timing maps for everything, the only timing maps i'm using are the high and low octain maps (which are the same) and the optomal timing map and the boost retard map. i log the truck and it seams that at wot it is pulling 4-6 degrees from somewhere. it's a drive by wire throttle and i'v increased the maps for them to not set a 1514 code. All the torque management is zeroed out and it has no traction control. i'm wondering if increasing the expected torque maps has some effect on the end timing tables? any input would be appreciated. thanks
