Even after the parameter access all the diesel emissions stuff is still locked out! Not tuning Diesels anytime soon. How do you get around this? Anyone have an older version?
Of course I can make user defined parameters. I don’t do any of that in HP Tuners, everything I do is in hex. What I said was HP Tuners does not allow access to the DTC’s through user defined parameters, they fall outside of the allowed address range. That is how it is with the Cummins calibrations.
