    Can't flash truck back to stock

    Just purchase a stock tuned ECM. We do this every day for your exact circumstances. $425 plus core. Or just google search your ecm service number, you will come up with companies that do this. I don't believe the tech 2 (dealer) will be able to flash over your (now) read protected Bosch...

    Boost

    Are you sure about your PID accuracy? It looks to me like your boost is (28.1-14.4)=13.7 psi

    LMM not responding to rail pressure tuning changes

    Known issue. This was an issue 5 years ago, that never rec'd attention because few ever dig into the refinement aspect of tuning, vs top end performance. Multiple dead threads exist. The feedback never got any traction back then because staffing would prefer not to solve a problem for one...

    Exhaust Brake - trouble, VERY FRUSTRATED

    Log your truck leaving the cruise control disengaged. A gut feeling is that a safe protocol for tuning may be to eliminate chances of traction loss (with slippery conditions), by deactivating or reducing turbo braking with CC. Full driver interface required. It is worth a shot.

    LLY: LBZ intake and mp install

    Look for an idle MAF of about 5.1 lb/min at 680 rpm. That is one check.

    LLY: Low rpm tuning efi live

    You never will. The engine efficiency is gone at these rpms, and you will not change that with tuning, it is a hardware limitation. BUT, if you have a ghetto intake with larger flow area, the MAF will see that as a lower air velocity, and limit fuel over a stock configuration. This can result...

    boost sensor

    help the guy who asked the question, if you think you have something important to say.

    boost sensor

    14psi is atmospheric pressure, aka zero boost.

    EFI Live Tuning Guru's, I need help!

    Does the truck have HID's? This is just a lob, but the noise these emit can be horrendous. We always prefer to deal with ECM's on the bench. You can ship it to us for a free eval if you like.

    Changing idle speed for no DPF

    Using B0701 ECT idle table?

    LB7: Lb7 ECM locked help!

    If you are at a dead end, just ship it to us, we will diagnose it, won't cost you a thing.

    LB7: Tunning Assistance

    Of course it is the deleted glow plugs causing the cold smoke problem. I personally don't see how that can be practical. How will you start it in December, unless you have some 200 degree air to put in the airbox? agree with most thoughts. You will have to increase idle pressure to around...

    LLY: Intake temp

    Stock LLY intake temp will get to around 160-170F (ambient plus 50) in AZ during regular traffic stops in the summer. We have had it as high as 232F when towing hard. A nasty issue, the fan creates the underhood heat increase that exploits the poor airbox design. When this happens there are very...

    Oil cooling

    Oddly reminiscent thread. Plan on 15 gpm at 3200 rpm, Mike. -10 is not enough if expected to handle full flow without excessive restriction.

    Fan help

    so many possibilities. First one (common) to look at with those miles is restricted air movement. Debris can be blown out with an air hose, but partial dismantling of the condenser and intercooler will make the job more effective.

    Question: ECM testing

    No, they have no bench capability. Give me a call.
