Another one for Pecky... or anyone else who may be able to help.


Trying to flash a UHP4 which contains an unknown PIN code.. Read the ECU data via tech2, hooked up to laptop, old firmware is 1.91 (i think) and new firmware is 3.something. Hook backup to car.. Go to hit F1 to flash download.. attempts to start and then fails spectacularly

Says something similar to SPS uhp4_util failed and then three lines below it

###-0000 ####-0000 Line-0000

Cant remember what the other #'s are...

I've tried reading/writing in more than one car... also tried downgrading my version of tech2 software as well.. Any known issues or have you run into this problem?

I flashed a UHP from 1.91 to latest version a few weeks ago no probs, its one i had installed and was all coded correctly and flashed with no issues.... confused.....
