    Trying not to sound offensive, but, good luck. Bosch ECU support in the software is limited, and that vehicle didn't really have any other ECU options at that time...

    Its comical that people even ask for this (and expect to get it) anymore. Just today it made headlines that a well known diesel tuner was sent to jail for a year for this kind of stuff. And one of...

    I would recommend fixing all known mechanical issues with the vehicle before trying to diagnose the boost control issue. If you have a P0016, then it sounds like you need to go over your cam swap...

    It's a 2019, so the BARO is on the LIN bus... Does anybody actually have a breakout harness for that?

    Based on the information you've shared, it sounds like your ECM is corrupt, and you'll probably have to get a replacement. Sorry

    Unlike the V8s where you can throw a stone from anywhere and hit five guys that have experience tuning them, the turbo engines are a totally different story.

    You're probably blowing your injection window because your fuel system is being overrun. When the rail pressure drops, the ECM advances the start of injection (SOI) event to compensate. If it...

    GM ECUs have a separate flag that indicates whether the diagnostic itself will run, the DTC settings only control whether the DTC is reported and/or the CEL is illuminated. Remedial actions like...

    Is it trifecta tune? If so, contact them, I've heard they'll loan out a flash cable for people in this situation

    Support could answer for sure, but if I had to wager a guess, you'd have to get it unlocked again. Another question is whether it can even be unlocked again since superchips already did it?

    The companies that produced the charger kits for the LGZ did extensive R&D and testing, and to compare the LGZ to the LCV is like comparing a can opener to a fingernail file. To my knowledge, none...

    Given we can't even get unlocked E90s now, this seems further away than ever unfortunately...

    There is a table that controls that transition point based on oil temperature as well (so you can avoid running high pressure at low temps). If it doesn't exist for this operating systems, maybe ask...

    Interesting idea! Unfortunately, wiring in a manual switch will probably result in random DTCs being set because the ECM performs oil pump control solenoid diagnostics by monitoring the oil pressure...

    Thanks for clarifying.

    Yes, an EVAP system leak could / would certainly skew your trims since it represents unmetered air / vapor getting into your engine. It is important to keep in mind both...

    How have you determined you have a vacuum leak, and more specifically that it's related to the EVAP system?

    U0100 means lost communication with ECM, so, yeah, it sounds like it's toast.

    Not sure off the top of my head. I know there is one, just don't remember what it's called.

    There are two ways GM software can determine which gear a manual transmission is in. The first is as you said, it calculates it based off calibrated gear ratios, transmission output shaft speed, and...

    12674052 is shown as having been superseded by 12704476, and, yes, neither of these appear to be correct for a 2017 LT1/8L90

    There are really only two versions of the E92, one of them is pre-2017...

    Now THAT is interesting, I hadn't heard it was the LT5 blower. At that power level, though, it seems unlikely that they would have needed to upgrade the injectors and HPFP. Once the parts...

    On some applications, the FSCM controls the fuel pressure, on other applications, the ECM controls the fuel pressure indirectly through a FPDCM, but never both.

    According to the service manuals,...

    Another possibility is you could change the VVT angle at idle, like the ghost cam people do. This will lower the cylinder pressures and cause the ECM to compensate by opening the throttle more. If...

    No, but the T93 is gradually replacing the T87A because the T93 can do the secure comms required on the Global B vehicles (T87A cannot). Makes sense to the bean counters to have only one TCM instead...
