Yes, psi = (27.809 x Volts - 20.717) + (baro - MAP)
And the excerpt from GMW 8774. I can't attach the whole doc here, DMCA and all.

In the video the fp dropped a psi or 2 which my screen shot shows. Boost drops off a little to pull the delta back in my favour.
You'll need to dig into this when you have time. You should see what...
Delta fuel pressure from sensor volts in yellow. How it should be, flat(ish).
Delta fuel pressure reported from fpcm in white. Taking a dive and not accurate to the gauge. 7 psi out at the end of...
Beware! The reported fuel pressure bit me in the ass once. Reading the sensor volts with a math transform is the most reliable.
...
Give this math parameter a whirl. Set unit as percent
100 * ([40001] - [50118.238]) / [50118.238]
The only way that could of happened is the ecm torque figure transmitted to the tcm changed between the 2 modes. I would be surprised to see that should both airmass models be aligned.
Why not use the right tools to diagnose? If you haven't got 'em, buy 'em. They're cheaper than a visit to the Snap-On truck on payday.
Actual torque (aka engine torque or trans torque etc.) is your x axis. It has 2 break points which define 3 zones. The y axis is a constant torque 'number' the trans will use as it's lookup value to...
Was meaning if you needed an explanation on how it worked.
ns158sl are you all over discrete shift torque? Happy to go over it if needed.
There is a few knobs to be turned. It appears from all my internet searching the fix is not public. I have a significant dis-taste for people hiding information, just small cock bull shit if you ask...
What's the go with the oscillating at the start, no way that was on it's own...?
Back out my throttle follower changes next time you're out. Your engine torque is a smidge on the high side but not...
What is the gist of what needs to happen? Might be able to work it out between us.
Just thinking for your testing, perhaps keeping discrete enabled might help as its giving a repeatable pressure for you to judge other adjustments against. Saying that it gets worse in that mode,...
Try this
Good quality log, can you re-do it with engine torque and idle adapt added. +1 for putting all throttle settings back to stock as Ed said. For me, usually min air and airmass A will fix this up and...
Yes that's right. Your air is high to start with which it holds then it slowly bleeds off. In the mean time you're pulling a heap of spark. All of that will be contributing. Get that part closer then...
To start with take 0.5g out of your start up air at the hot temperature. Get this bit right then look again to see if it's still out. Add IVT, Minimum airflow, Engine runtime and Engine off time to...
Generally they only lock it in their last gear once the multiplication has gone.
This guy loves to lock up at the big end

Wideband is definitely leaner on the 30min restart vs the 16sec.
Don't hit me. Back to basics, in the old days they used to say 3 things...
Looking forward to seeing what the wideband reads as it's cranking and running up.

The downshift lock out tables are hidden. The vss settings must be correct. Try it out, do 4000rpm in 3rd and initiate a downshift to 2nd. It won't do it.

You mean a tap shift switch box?
If yes, the protection is built in. The mph down shift inhibit values are in the background tables.
Don't be a dick.
The cunt needs to warm up and be sending data before cranking ya fuck stain.
Love you Ed :chug::cheers:
Good call,
cringer are you able to get the wideband ready for logging prior to crank? Would be interesting to see what it's doing
