A couple of months ago, the truck seemed to have died during a reading of the ECM. OK, that's not supposed to be possible but . . . it did restart but only after sitting for a few hours.
Erik (ScarabEpic22) came over last Friday and flashed it with a tow tune from SoCal Diesel along with an economy tune and the OEM stock tune. When we roadtested it, the truck flew on tow tune but the transmission coughed up a P0735 code at WOT during the 4 > 5 shift.
So, I reflashed to the OEM tune the following day in preparation to take it to the dealer, but then we couldn't get the transmission to act up. So today, I reflashed back to the tow/combo and took it for a spin pulling our 5th wheel. The transmission spit out P0735 again while we were pulling a moderate grade at 1600 in 5th.
So we came back home to flash it back to OEM, but during that flash the EFILive hung on a blocking shortly after clearing the ECM. It repeated the attempts to unblock about 30 times before I told it to stop.
Started over again. Same thing.
Stated over again, but now it says it can't communicate with the ECM. http://forum.efilive.com/images/smilies/new/bad.gif
