I bought a LMM a few months ago. I was planning to put efi live on my truck. I have a MotorOps auto cal from my last truck. I did a data record on my LMM. When I put it on the computer the data log shows DSP5 (LBZ-LMM). I assume this means somebody has already put efi live on my truck. Is there a way to find out who did the tuning on my truck? I would hate to use it and find out it is crappy tuning.21495

A better way to check is look to see what OS number the ECM is running, on an LMM if it starts with a 5 then it is a DSP5 tune (eg 52628594).

I just checked. I have the factory operating system on it, so I'll start from scratch! Thanks for the swift and accurate answer! It is confusing that the data log shows dsp5 Lbz LMM
