[Diy_efi] Diesel ECM Programming

[Rick McLeod]

I do know that there are some folks tuning the cummins (I think) packages that are used in class A motorhomes, as when I was shopping for one comparing one to another, the salesman had names of some folks that would turn up the heat on one I was looking at, as the package was hardware wise identical to a different brand, but about 75#/ft shy on torque, which he said was the way they charge more, everything is identical except the tune. Some of the marine engines are the same way (or at least used to be) that the engines are identical across a couple power levels, and the lower one is simply detuned, seems to be an expensive way to go until one includes the setup costs and it really makes sense then. reduces the castings/parts/assembly by 1/2 for every time they make a new model by detuning one slightly larger.
 
Short answer, make friends w/ a RV shop, as their is a big market there, especiallly in the high end ClassA lines, the $250K and up ones!

Has anyone on this list done (or know of someone who has) hacking of big diesel engines, Cat, Cummins, or Detroit?  What kind of hardware and software is available to do these engines?  Myself as well as some other people want to crank up some trucks.  

Thank you,
Arby
