Converting an LMM tune to LBZ tune

[wdw012]

Does anyone know how to properly copy and paste an LMM tune to an LBZ tune. Tried copy and pasting, put feel like i have missed something. There are tables in the LMM tune that are not in the LBZ tune, and visa versa. After i copied the tune and loaded it, something was seriously jacked up with the truck even at idle.

Thanks in advance

You can't. LMM have 7 hole injectors vs the LBZ 5 holes.

One of the problems you will run into is the main injection table. The LMM only has the main event in this table and the LBZ has all three events. Try changing the table B0720 back to a lbz map.

is there anyway one of you could take a look at an lmm tune i have and see what i would have to change to make it work with an lbz

I believe you have this backwards, and off. LBZ use 7 holes(like those before), and LMM uses 6 holes. It CAN be done as I have converted LBZ tunes to LMM's, but it is ALOT of work to do it. Like said above, some tables don't match so you can't just script it over. And the LMM uses alot more tables so some have to be condensed down and blended. As for the difference between injector sizing due to the hole difference, it is a SMALL difference as the LMM uses larger openings to offset the fewer holes. It is common to swap in LBZ nozzles in an LMM since the fewer orifices in LMM's makes them not like being oversized and run clean.
