i can't re-program my 2001 8.1l tcm allison 5 speed
I can't re-program my tcm the bootloader keeps getting rejected and the new licence wasn't used on my v2 efi live with ver 7.5.5. I once had an allison tech try to re-program the tcm but was told the tcm was the very first controler that was put out and wasn't re-programmable. I copyed the program and attached it. Any help would be appreciated.
thanks

hitting reduced engine power now and can't shut it off
Thanks for answering my thread, for some reason if i open my allison file after opening the pcm file not all 3 (read, part flash, full flash icons) will be lit up. when i close down efi live tune and than re-open it up than all the icons are lit up and i was able to re-program the TCM. now for some reason i keep hitting the reduce engine power when i do a full throttle pass. i have changed the process enablers to not reported for 1514 (i maxed the gragh out to the max efi live value and still trigger it) than hit the DTC 1781 and turned it off. When i hit the reduce power mode and the TDC that now comes up is tdc102 which is set to C non emitions. i'm running a costom 2 bar operating system for my 2001 4x4 gcm p/u truck. the engine is a 604 cu twin turboed engine and is starting to make some real power now, i've only been running about 5 psi of boost. Am I at the airflow limit of the program or have i just not shut something off? The transmission is fully built with all the good guy parts and i'm running a ATS co-pilot as well, the transmission seams to be shifting well, but maybe it is telling my ecm to reduce power, i will post my tunes.
thanks for your help.

reduced power mode and no tdc codes
I tried to max out c6101 and it didn't stop the reduced power problem. When i retreve the tdc codes but there aren't any that explain why the reduced power mode is being triggered. All the transmission process enablers are turned off from the factory in the ecm and in the allison program there aren't any process enablers to turn off. I get the feeling the problem lies in the tcm telling the ecm to reduce power. I turned 1514 code off and 1781 off but still the reduced power comes up on the display next to the tach. any help would be great.
thanks
