I know live tuning would have expedited the testing of the MTW turbo's, but for anyone doing just your normal tune, intake and exhaust it would be a waste of money. Once you start getting into relatively uncharted territory though, like a new turbo ( MTW, RCD, Non-VGT) it can be an asset. While adding injectors and a turbo seem like a minor addition, with all the new options that havn't really been in the hands of tuners yet, live tuning would be great. Anything above say 205's would probably benefit as well as compounds. JMO
This was along the lines I'm thinking, useless for the electronics only builds, could have accelerated the tuning of the MTW's.
for the sake of this thread maybe someone would like to explain want is involved in "Live tuning" for those who do not know what it is.... JAT
kdogg85, explains it pretty well. Basically, the tuner with a dyno and your truck, fine tuning everything in a particular file.
I believe this is possible or is at least theoretically possible anyways. I know tuners with a loaded dyno can simulate almost whatever load they want provided that the load can go that high. I'm sure Matt knows how Bill operates his dyno and he adjusts the load on the dyno to account for the weight of the truck so I would presume he could just keep jacking it up to the "weight" of a trailer.
I am interested in seeing if this can be done, and if anyone has had a tow file written this way. If I could get a tune dialed in for 26K gross, it would go along way for my build.
First off, for considering live tuning, you need to know everything about the tuner him/herself. You don't want some joe blow tuning your vehicle.
Now, it is basically the same thing as the tunes you get through email. Except, you can have the truck dialed into what you exactly want(within the capacities of your mechanical parts of course.)
It's mainly recommended for folks who have wild or very large capacity combinations(ie, large turbo, compounds, big injectors, etc..) The basic 155/stage 1-2, or pmax would benefit some from this but nothing like what the big sticks(190's plus) and chargers(non vgt's, stage 2's and up) can do. And you get the tranny dialed in exactly as well, that is a nightmare of parameters from what I have seen on the 5r110.
Compare that to custom tunes from canned tunes. The tuners do an excellent job for what they do, but they cannot possibly know the details of every truck and subsequent quirks that every truck has.
Hte best I can tell you is have all the hard parts on the trucks before you get it tuned, then you can really see what the truck will do vs tuning it and then getting some result.
Thanks for your input. I intend to get all the hardware installed before moving toward getting my truck live tuned.
