There is no MAF priority mode on these like the older GM ECMs. On some applications even attempting to tune the MAF translation table causes random weird behaviors, but I've tuned a Whipple setup...

I see you edited out that comment, but I caught it on a screenshot beforehand (happy to post it if you try to deny that you said that). That's remarkable though, you're saying they actually...

That is incorrect sir. When I had my V Sport with their tune, I sniffed the CAN bus, they are definitely flashing the TCM. I don't know enough about it to know what they're changing, but they are...

Short answer: No

Long answer: No, unless you know someone that can write you a custom OS modification that can somehow detect a shift is in progress and either pull timing or otherwise impose...

On this application, the BARO sensor is in the MAF assembly. If it reads vacuum, yes, that means your intake system is restrictive.

These engines, compared to the rest of the GM DOHC VVT engines use a unique phasing strategy. Both cams are mechanically fully advanced when in their parked (0*) position. From a mechanical timing...

Ah, that would explain it. Newer OE calibrations will inhibit cruise control operation when traction control system faults exist (stabilitrak light on).

If your truck is 2WD but the transmission...

It could be a software incompatibility between model years, as was suggested above.

I'll also point out that on the newer OE calibrations, they are more sensitive to having correct gear / tire...

On Global A ECMs (like this one), unless you modify the OS, once the MEC is set to zero (which generally happens the first time it gets flashed), you cannot change the VIN in the ECM.

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...

Not only it has the dreaded E90, but it's the Global B version which isn't supported at all...

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...
