    The software should be covering non-us vehicles. The ecu are the same with the only exception that if access is not available when you try to initially read the computer then the vin number would have to be submitted to HPT Tech and added to the system so you can continue access.

    as for available features i have not personally seen ecu file to list of features it has but i can say that "generally" vehicles equipped with factory boost normally receive these features:
    Injection Window Control
    Boost Solenoid Control
    Rev Limiter Control
    Torque Management Control (to a degree, depends on ecu how much control you get)
    Transmission Control (some of the newer vehicles are receiving this but from experience its not normally released right away with the ecu features. Again depends on vehicle ecu if that will be available to you)
    and last but not least
    DTC Code priority control (this would shut a DPF code off permanently but that doesnt mean the computer stops controlling that system or excludes it from the ecu testing the system and registering the system as fail/pass)

    To say for sure each feature is offered with 100% confidence i would have to fish through a tune repository file and i am not currently on a device that would allow me to go check.
    I will look some time today when i am back at the shop but i suspect HPT Staff will eventually roll around and cough up a more reliable and definite answer that will trump anything i mentioned here.

    Everyone seems to have gone quiet on the 2.8 diesel. How is everyone going with these? Anyone upgraded their turbo yet?

    I'm at a bit over 220 hp at the wheels, but pretty much hit peak airflow at 2800 rpm with the stock turbo kept at 30psi. Not sure how far anyone has pushed the stock turbo as far as boost goes. I tried the boost a bit higher 33psi, but only gained a few g/s of air. Ten percent extra boost for another couple percent airflow. From info I can find on the net, these units lose their efficiency after 26 psi. Might be wrong, but real world evidence and logging does seem to back this up.

    Anyone else had a play with these lately?

    Hey guys. Any updates on the above? I have a 2017 Holden Colorado without a DPF. I?m looking at an ECU reflash but have no knowledge of tuning. Would anyone be able to point me in the right direction of where to start/who can help with tuning?
