How is this supposed to work
I loaded ID's SCT Tow tune with Brake (poor man's Jake Brake) and nothing happens on deceleration... Go up to 60mph take my foot off the gas depress the brake and the RPMs drop down under 1000 and no compression braking occurs all the way down to stop.
If I press the Tow-Haul button then it acts like it did with the stock tune. The tranny comes out of OD. The TC stays locked up and the VGT enabled compression brake comes on. How is this supposed to be different than the stock program as far as the turbo-brake goes? It did that much with the the stock program. I'm confused.
When it's out of Tow-Haul mode it acts pretty much like the Economy tune except the shift points are much higher... not as much as with the stock tow-haul button pressed... maybe 2200 to 2300 rpm shift points. It also doesn't seem to go into lockup any differently than Economy. Another thing that surprised me is that the shifts are really soft. I thought they'd be firmer for Tow mode.
I thought I might have the wrong program so I emailed Eric and he sent me another. Did the same thing.
I'm towing the camper on a trip tomorrow and admittedly I should have tried the tow mode sooner but I'd just like to hear how it's worked for others.
2005 F250 XLT crew cab used for camper towing, kid hauling and commuting:
Banks Monster Exhaust, Banks Ram Air Intake, SCT with tunes from Innovative Diesel, Zoodad mod, High Idle Mod, Reverse light floods, ARE Shell, HAM Radio Antennas (80m-10m screwdriver, 2m, 440, 6m whip)
First 25k was run on Biodiesel but it's too much trouble so I'm dino-diesel only now > 50k
