    938M Regen data

    I thought the same, he did not show it but possibly did reflash with latest calibration, being a dealer I will assume they did that first. I did recalibrate to latest with same results, I also reset soot load twice I think with same results....ordered new ECM....we will see!

    938M Regen data

    It is common practice on some other engines to use post injection( open injectors when ex valve is open) instead of using a down stream injector. I was talking to a cat tech that confirmed c7.1 does. I may have read it somewhere else also, if I find it I will post it.

    938M Regen data

    You are correct that no fuel is injector like a 7th injector however it does use post injection to introduce fuel into the exhaust that reaches the DOC to create heat in addition to the back pressure(at least thats how I understand it). Another way to monitor all data during a regen is to start...

    938M Regen data

    No thoughts of delete.....yet. I really want to figure out why its not burning off. As far as replacing, it sure seems like DOC is not reacting to the added fuel and creating enough heat. During a regen it only gets to around 650 deg. performing Aft, sys function test went up over 700Deg pretty...

    Cat 304 isn’t charging

    You say 15.5v at alternator, what about at battery? Possibly broken wire or circuit breaker between alt and bat. Does this machine have a intake heater or glow plugs? If those are stuck on will suck all the power from alt.
