Yep, I've tried that. Also tried starting the procedure while in drive. Went back and re-read posts and stickies here just to make sure I wasn't losing my mind.

I believe the parking brake is...

Having the same issue on my 2018 2500hd (6l90e). I also can?t access it through ACDelco SPS / GDS using my mongoose interface, it's just not even listed as an option where it should be, so I?m...

I like the Mongoosepro. I haven't had any issues with it.
Getting the right version of java installed do make SPS happy, especially on windows 10, it's a pita, but that's not the mongoose's...

I use a bcm in my setup ('15 6.2l&8l90 in a square body k10). Using it for everything you said, except backup lights. Wire it in like factory using the factory sensors (brake pedal position,...

Got a chance to look at the Advance adapters piece a little more. It looks like from their installation instructions that it is a slip fit, so not sure how you'd keep it in place. Wouldn't be hard...

Sorry for the poor quality

I don't see why that wouldn't work, I wish I'd seen it before. You might have to shave a little off the 205's input for that, but I think it'd be worth it. I wonder how the reluctor wheel attaches...

No, I didn't modify the output shaft. GM doesn't seem to over-engineer anything anymore, so I wanted to keep all the splines and get as much engagement to the transfer case as possible. Output of...

One more thing to be aware of... In mid model year 2015, chevy changed the VSS to a digital sensor. There is a bulletin about it floating around the internet. Mine was made in May of 15, so I...

For the 4x4 guys swapping a 8l90 to an old style passenger drop transfer case.

Had a few pm's asking about this, so I'm just putting this out here. Sorry for the jumbled post, it's just a coy...

Jason, replied to your pm.

Yeah, didn't know if you incorporated a bcm or not.

Try it with the park brake set.

Kinda hard to make a guess without knowing what speedometer gears you are running. I was out in the shop and came across the stuff I took out of my 205. The "driver" (plastic gear on the output...

Have you seen this?

Why not just machine the speedo housing of the 205 for the correct 40ppr setup?
...

I would think that would work for the fuel system.

The third wire for the fans is the PWM control. It originates at X1-59 at the pcm, then goes to X105. X105 connects to the forward light...

I'm gonna guess that's where that 84psi relief valve comes into play.

Not sure, I changed directions on my fuel system when the old standby walbro 255 and vette fpr didn't look like it was gonna...

Google 19303139. This is for the LT1 controller kit, below is the exert that talks about fuel pressure. I ended up just running the fpcm.

This control system is intended for use with a...

If not using the fuel pump control module, GM says 72psi.

DTC's provide any clue (disable any U codes in your tune)?

Are you building high pressure fuel pressure? (log fuel rail pressure (sae) while cranking)

OS/ VATS Patch 1 & System/ general tab.
These are the two places VATS resides on my 2015 OS, no problems using HPT to disable them.

Make sure you have the latest HPT.

Does anybody have a log file with this being scanned? Does it show pretty close to the actual trans gear ratios?

I've got about a 10% error in first gear (calculated = 3.984). Curious what a...

Is there a way to determine the PID? It seems the oil pressure has changed in the Gen V stuff, can bus gage no worky...

Well crap, was kind of afraid of that, I have bigger issues then if that's the case. I was really hoping I had created a mis-match between some tables I can't see and the driver demand. First gear,...

Has anybody swapped gears yet? What effect does it have on the driver demand tables (which are in axle torque)? I assume it is not just a linear relationship otherwise the gear tire wizard would...
