LB7 Lope Tune

[Hoytmax Diesel]

I got an LB7 duramax and wanna make a lope tune for it. but i dont know where exactly to start anyone with any advice

[LB72004]

there are several ways to do it but an easy way is to increase the mm3 in the idle area of the main fuel table.

[dansdieselp]

Throttle based injection quantity. Go to 0% at 600rpm and put 50mm3 in that cell.

^^ thats a better way. try that first

where exactly is the idle portion in the main fuel table

i would start with the throttle based one first.

if you do some logging then you can find out how much mm3s and MPa your truck uses at idle and change only the corresponding cells. i hi-lighted the average area but it may be more or less depending on temp, altitude, age, fuel, etc. logging will show you where you are at. the idle table for temp and the throttle table are the easiest ones to modify as no logging should be needed and is easy to revert back when you get tired of it
