Joecar, please email your sae_generic file with that calculated PID.

Rick,
It's on my other laptop which has V5 on it...
I have to get it back so give me a few days...

Successfully added my first custom PID tonight. Thanks Joecar! 8)

Here's the data logged from today: supercharged LS6 - 800+ IRHP.

Played around with the dx constant but it didn't change it by very much. It's high by about 2x the actual I'd say. Got the right weight in there so I'm pretty much scratching my head at this point. :?:

Rick,
You're welcome (I still have to get my other laptop back though...);

Your GVWLB may have gotten converted to kg and is now being interpreted as lb...
If the GVWLB is getting smaller each time you view it, try this...
Multiply your actual GVWLB by by 2.2 and enter in this number;
(Once you enter this, do NOT view the GVW since this will cause it to be divided by 2.2 again (...2.2 is lb per kg...).)

Also check that VSS is in MPH and not km/h.
Also use the "densest" logging mode (most frames per second).

Also, V7 and V6 have a "builtin" pid for RWHP which uses this equation.

I am also having questions about the values of GM.TRQENG mine is peaking at 319Nm at about the right place but the value is wrong by about a factor of 2 or more. Maybe its 2.205 the kg to lb problem.

Can anyone throw some light on this.

Got caught out with this one as well
On a cammed LS1 VY Ute going lean during a FULL THROTTLE TUNING session. read this post reflashed with it set on 100% and it went pig rich to 10:1
On a non cammed ute of which I'd done several I just tuned around it without knowing I had a problem as such but with the cammed ute the fuel flow just wasn't enough!
Ended up with 250rwkw on 94% D/C at 6500rpm.
Interestingly enough all my non full throttle VE and MAF tuning was still spot on and required no changes whatsoever so this obviously only affects full throttle pump voltage.

Cheers,

Mike

DaveB,

You don't happen to be driving a Ute do you??.
You can pretty much ignore that value on Utes, GMH screwed the cals to use that Torque figure for other things (like slowing the F.Pump down at WOT).
Using the navigator in the tuner take a look at parameter number 'B1904'.

Cheers,
Ross

Its effects below 135Nm or whatever the torque value at the top is set to. The higher thats set - the further it extends in torque - being at a low pump output.

ahhhhh thanks for that Steve
