    Hi, would it be possible to have someone email me a good 088 xdf file? I am struggling with checksum failures and not sure if it is the XDF file I am trying to use.

    EDIT figured it out, had the checksum plugin in the wrong location.

    Hey, if I used this XDF without moving the plug-in properly at first, will it ruin the file? I realized my mistake and moved the plug-in into the tunerpro folder, and then continued. When I load my file into PCMHammer it shows all checksums being good, should I also download efi live or something to double check?
    I have a 1999 Silverado 4x4 1500 5.3l LM7, with the shitty 4896 PCM, I’m upgrading the OS to the 12212156 OS, doing efan swap, enabling both battery terminals to try and use the GCBM from my 06, and swapped the ac pressure sensor in place of the pressure switch. I’m fairly new to this, but have spent the past several months Obsessively trying to learn/read every drop of info I can find on tuning and changing OS. I don’t want to brick my PCM, as the only other PCM I have is a blue green

    EDIT- I should also mention I’ve purchased an OBDX pro GT GM device to flash this bin onto my pcm

    pcmhammers checksum tests are enough, if it says its ok, its ok.

    Thanks pal, I went ahead and flashed in the 12212156 so, it’s running great! Only issue I’m having is a PO171 and PO174 code. This never showed up prior to the OS swap, could it possibly be a different O2 sensor type/pin out? I swapped this OS into a 99 Silverado 4x4 1500

    In case anyone was curious, the lean code was due to the 1999 fuel injectors being only 19.8lb/hr, but the 12212156 OS being cal’d for 25lb/hr. I swapped in my parts trucks good condition injectors, and Voila! No more code! Now I’m about to start dialing in the tune, I’ve read hundreds of articles about tuning over the past 9 months, I think I’m ready to start! Anyone have any tips/tricks for tuning using tunerpro RT?
    ALSO, if anyone has an ADX/ADS file for data logging in tunerpro with the 12212156 they can send me, I’d much appreciate it!
