Hey David,
I have been running my Livewire for nearly 5 years. I dig it. I have a 40hp Tow tune from Innovative Diesel and a 60hp Daily from DP Tuner.
Dp Tuner said it was formulated for a van that was in The Cannonball Run a while back. I like them, but will like them better once I go to 4:88's. Which should also get my speedo dialed back in.
I actually, I like the SCT Tow Tune the best, but it doesn't lock the converter at low speeds. I will probably see if Dusty at 1023 Diesel can help me out after the gears. I want to get a trailer similar to yours, and they have more experience at working with tunes for people that deal with climbing/towing extreme grades out in Alaska.
One caveat about the Livewire, is that if it goes without power for too long, it will take a ********. I have twice had to send it in for them to reload it. $100 each time..... Other than that, I love all of the many features. I refuse to use sandpaper on my PCM for a live feed through a chip, so no Hydra for me.... I prefer flash tuning though the OBDII.
Love the bumper!
If it gets powdercoated your got that right, ain't going back! lol
I'm not rushing on this project, not really a priority at this point but black it will be! I'll finish it in between other projects. Talking about other projects I opted to do my poptop in aluminum. Goal would be to have it done by end of July as I'm taking off for all of August throughout BC in the van...
I also installed a SCT Livewire+, love it and hate it! Love 'cause it's really awesome, all the guages and wakes up the 6.0! But hate it as even though they say it's compatible and pre-loaded with tunes well... not really. You have to pay extra to have a tuner send you tunes at extra cost (and that SCT isn't cheap to start with!). They also say it will adjust your speedo for new tire size. Again, maybe on a truck but no go on the Econoline! My rant...
Cheers
David
