Dude, only tip I got for the fass is mount it as close to the tank as possible and below it if you can (not always easy
). Then eliminate the lift pump on the side of the block. On a side note, I've had issues with fass motors not working but everybody else raves about them so....
I know in 1999, the cummins ecm communicated on the same ccd bus that the pcm, bcm, radio, cluster, etc. all communicated on. So you do have a port to the ecm through the obd connector. Now, I'm going to assume that the ecm would use the same j1962 protocol that the other modules use to communicate on that bus. That's how all of you're tuners connect to the ecm. To use the j1939/cummins insite, you'll have to use the cummins bus connector. Or figure out a way for insite to communicate on 1962 channel.
You'll have to talk to a brain/engineer at edge, not some tech support clown.
Family wagon, The ecm cummins used(number of ports 1,2,or even 3) depends on the number of pinout options the application required. The dodge truck ecm has just about all the pinouts on the ecm used. Your dodge trucks run a ccd data bus to the gauge cluster, while your busses run individual gagues. Those extra wires right there would have necessitated the upgrade to the 2 connector ecm on the busses and were not even counting all the other accessories that are on busses.
Dude, the power levels are primarily dictated by the pcm calibaration. Now each different power level may require different parts(pistons, injectors, injection pumps, manifolds, etc) to reach the rated rating. You can load the 275 horse tune into your 210 engine, and you will achieve a gain in hp. But how much more you'll gain I'm unsure of(I don't think it will be all 65hp). They also change those parts to increase durability too, so I would change the hard parts and the tune.
That comp box doesn't change anything in the ecm, It just fools the sensor inputs into the ecm, leading the ecm to believe it's operating in a different environment then what it actually is. I'm not a fan of them, but they do work.
