Is it possible to log or monitor things like transmission slippage, transmission input torque, excreta? If so, how do you do it.

I'm not sure about the 6speed allison PID's but the 5speed PID's you can ceate a calc PID that uses the trans speed sensors to make a slippage PID. I haven't done it and do not plan to since my trans isn't complaining about anything I've thrown at it.

Kind of off the subject, but how do you create a calc PID? I was trying to make one for boost pressure. I can monitor the boost sensor voltage output, but would like it to read in psi.

X2 :think:

Did you read the instruction maunal? Not to be a smart ass or anything:)

It does go over it. It can be a lil tricky to follow at first so if you run into any specific problems let us know :) Its a pretty lenghty process to type out but once you do it a bit it starts to make sense

What model Duramax do you have? If it's an LB7 or LLY, EFILive already supplied a calculated PID for boost named CALC.ACTBOOST. Calculated PID's are located in named Calc_Pids. txt located here, \MyDocuments\EFILive\V7\User Configuration.

More info is available for calculated pid's by opending the scan tool, press F8 to view selected Pid's, then right click on the Pid in question and select more info.

Thanks for all the help everybody.

Yah thanks, I have not read the manual in over a year and don't remember seeing it. I guess I wil have to look again :o:

"Calculated PIDs

Calculated PIDs are derived from existing PIDs by evaluating user supplied mathematical equations."

I guess the manual did mention calc PIDs.

I been working on a boost pid for the LBZ and it's kicking my a$$. I'm a retard but if I get it to work I will share it :D

If you know how to create a PID then you can right click on the "Actual boost Pressure" PID and select "info". This gives you the formula for calculating the actual boost. All you need to do is create a new PID and substitute the "GM.BOOST_DMA" PID with the LBZ/LMM PID "GM.BOOST2_DMA" and I'm not sure but there might be a new PID for the BARO reading on the LBZ's and LMM's which if so needs to be in the Calc PID also.

You cant figure out the equation to use or you are having trouble writing it in the correct file?

I got it to show up in the cal. pids with everything that I want but the value is way off for some reason. I have not messed with it lately I spent 2 hours on it the other day but I will keep trying. I got to learn this myself so I can make more. :D I will beg for assistance if I can't figure it out. :D

if the value is all fubar then your equation is jacked some how. Post it up and what you want to do :)

Its the two bottom ones if anybody that wants it. I finaly got it to work Phillip I was trying to use sae.baro and sae.map and it would not work. I just used the inHg to psi conversion formula from efi's tuning section so it is off like a 2 tenths of a psi I think.

Sorry I did not realize that I hosed this thread and threw it off topic, move if needed.
Thanks
