    2.8 Babymax "Continue Driving" after delete

    Have a 2016 Colorado with the 2.8 Duramax. Did EGR/Cooler and DPF delete. Runs perfect. No codes. But after a week or so of driving the "Continue Driving, Cleaning Exhaust Filter" message was displayed in the dash. It went away after shutting the truck off, but has come back on one other time. What am I missing in the tune to keep that message from coming up?

    That doesn't sound like it's a proper delete tune, did you do it yourself? Do you have any post injection events actually happening while this message is being displayed?

    I did it myself. I haven't watched for PI events. If the ECM isnt seeing soot load anymore, what is commanding it to try to initiate a regen?

    The sensor all way in the back of your exhaust with the two rubber hoses needs to stay plugged in with the hose looped back to itself. Clear the codes (even if you don't have any). This fixed my problem

    I thought hp tuner did not support delete tuning. Would anyone like to explain how to get around the SCR/DEF fluid. I understand other tuners support this put I already have the HP unit.

    Looped the hose. Still have the message appearing on the dash. I'm at a loss- How can the PCM think it needs to go into regen if the delta sensor is reading 0 delta (hoses looped should show a net zero reading)? I've gone through the tune file several times- I don't see anything else to 'turn off'. Is HP Tuners incapable of doing a delete on this model?

    once it asks to do a regen you're screwed. you need to put all the equipment back in to clear the condition.

    So before you removed the exhaust you needed to do a forced regen so the ecm was set back to zero.

    Regeneration isn't only based on pre and post DPF pressure. It will command a regeneration After X amount of miles or X amount of run time, even if it doesn't show any pressure difference. In order to do a true delete tune you'll need to use "User defined parameters" and add them using either WinOls or Tuner Pro. If you don't know how to work in Either of those programs and have never messed with Hex and Binary data, unfortunately it's a long road ahead....

    Makes sense on the mileage based regen. I assumed it had such a strategy, but wasn't sure. Its been decades since I've done any hex work. Does anyone here have the ability to create the file needed to add using User Defined Parameters?

    You can't do this with HPT, without knowing where the SCR switches, etc...are located--and they definitely don't give you that info.
