    Hello folks
    Been messin with this swapped Viper powerplant (Gen4 2008 in a Roadrunner) that is standalone using all the components from the Viper. Tuned with HP Tuners but can?t seem to get it from going into limp mode. P2104 always sets no matter what I do. I?ve done the throttle relearn many times with a Chrysler and hp tuners. Only thing changed is the maf location. I?ve disabled air flow diagnostics and deleted the code but it changes nothing. Anyone with ideas?

    Having exact same issue with my 96 Ram 1500 5.9 pickup with a 5 speed swap. Turned off all auto controls and CEL is now off but still have a couple P07XX codes when reading with the scanner. Would also like some help. Any help appreciated.

    bump for this. I have a 2006 Viper, customer did aftermarket exhaust and need to turn off codes for the rear o2 sensors. I went through and disabled them via HPT but the CEL is still coming on. Can anyone help with this?

    What is needed to read & flash a 2003 Viper? Listed as supported. I can't get anything to work. 2003 supercharged viper that was tuned 20 years ago locked with whatever PVO was using? Guy is begging.
