View Full Version : Load Percentage PID/Calculated Value

OK so does anyone know how to make the Load Pct PID actually work on a P10? Every P10 Ive tuned starts at like 30% load at IDLE and goes to 100% by the time you're at 25% throttle position.

How does the load PID use MAP, as in what is the equation behind the scenes so I can try and figure out a solution?

Having a commanded AFR would be nice too, last I checked SAE.LAMBDA, GM.EQUIVRATIO and GM.AFR didnt work...

Bumpity bump, Id be happy just knowing what parameters are used to calculate the Load % axis in the VE tables so I can make a calc pid...

Have you figured anything out with this?

Shawn posted (or at least I thought he did) about the formula for the standard LS1 Load % PID. Unfortunately that uses GM.MAF, which we obviously dont have because we're SD/alpha-n.

Ive heard that TunerCats has the VE tables in a normal format, not sure but I believe g*K/kPa so I know thats part of the equation.

Yes, I had it posted for awhile, but figured it was not applicable...:).

I have TunerCats, I would be happy to take a look at a cal if you happen to have one in .bin or .cal format. Let me know...

Ah dang Mike, I dont have a P10 file in anything but .tun/.ctd. Probably could get one in HPT format too.

Anyone got a .bin of a P10?

I will check on the Monodax website, I think I seen one there a while back. Can't look at the cal tonight anywho as all my Windows PC's are down at home and all I have up and running is a Mac (go figure) and our tuning softwares and Mac do not play well together!!! I will see what I can do for ya!!!

Edit: Got one.....says it is for a '04 Envoy 2wd with a LL8. I will take a peek tomorrow. What table are you looking for again???

The VE tables, what are the units? RPM vs. ??? In EFILive its RPM vs. Load %.

I attached two screenshots of what fuel tables are avaliable, pick out which ones you want to see and I will get you the appropiate screenshots!!!
Hope this helps

Wow, there are definitely a few more params available in there.

What does A.E. stand for? Like Delta MAP A.E. Multiplier Vs. TPS.

I would like to see some of the first 9 in the second image (starts with % Vol Eff Vs. RPM vs. Load, only the single fire tables). Would like to see what the Mountain mode references are, never heard a reference to that before.

Thanks Mike, appreciate it!

Wish TC was like EFILive and you could look at tables without buying it. Plus I think you have to buy it through JET now anyway.

I bought my TC through Moates, but I am a Roadrunner owner, so I am elegible for the program. If you don't want a Roadrunner, your only options are Jet (customer service sucks from what I hear) or Wester's Garage (not sure of them, mainly 6.5 diesel, but does cars too). Mainly went for TC because it is more cost effective for my shop when doing gear changes, tire size changes or the occasional 'farm or off road' cal for a 250,000 mile farm truck. I still use EFI Live for any serious tuning, as TC has no scanner or RTACS or anything of the sort! I am guessing AE is acceleration enrichment, cant tell for sure as there is no help file for this cal. . Looks as if mountain mode is off, I included it. but doesn't look as if it is on!!
If you need more screenshots, let me know!!!
