2000 Holden Commodore, PCM running 2002 Holden only program, MAFless. I hope to get a chance today to log the new spark PID's.Originally Posted by Drake

O.K, tested the 3 new Spark PID's on the car today.
It looks like the Transmission Torque reduction is the problem.
At least now I know. I'll go hunting thtough the Trans Torque reduction code to see why.
Scan Spark is what the engine see's.
Trans Spark is the amount of timing 'subtracted' via the Transmission Torque Reduction algorithim from the Base Spark value which is derived from the main timing maps.
I hope to get these 3 new spark PID's in the next update, all of the 2002+ O.S's have been added already.

Ross,
This is pretty fascinating information you've come across! 8) I'm very impressed, as it gets down to the root cause or at least points at the likely suspect. Once you've picked apart the code, let us know what you find.
All my best,
Steve
Steve,
I spent some more time on this today but in the end I've decided just to get around the problem by disabling the TCS and Torque Control spark systems.
Instead I plan on finishing off adding the 3 new spark PID's into EFILive before the next update.
Cheers,
Ross
UPDATE:
4 new spark PID's will be in the next EFILive update due any day now.
1 - Trans Torque Reduction Spark
2 - Traction Control Spark
3 - Brake Torque Management Spark
4 - A/C Compensation Spark
EFILive now has a total of 18!! spark PID's, no other scantool comes close to that number.
We have already had many complements on how great these special PID's are (even though apparently they have never been seen before :roll: ).
At least you guys won't be left guessing where your timing figures are coming from.
Here's the list -
1 - Base Spark
2 - Coolant Temperature Spark
3 - EGR Spark
4 - Induction Air Temp Spark
5 - Cat Lightoff Spark
6 - Equivalence Ratio Spark
7 - Driveline Smoothing Spark
8 - Idle Control Spark
9 - Total Torque Control Spark
10 - Burst Knock Retard
11 - Run Spark
12 - Flex Fuel Spark
13 - Cold Engine Noise Reduction Spark
14 - Trans Torque Reduction Spark
15 - Traction Control Spark
16 - Brake Torque Management Spark
17 - A/C Compensation Spark
18 - Cranking Spark
Unless the next update is delayed one day the 1999,2000 & 2001 cars/trucks will not be able to see the four new PID's, sorry guys, if they don't make it in this update, the next update for sure.
Cheers,

Just an update, it looks like they are indeed offering some more PIDs in the upgrade that just came out.Originally Posted by AllCammedUp
At first you lost me there, but then I figured it out.Originally Posted by GMPX
"...tapped into the heart of the PCM to deliver never before seem parameters in the area of Spark Advance and Idle Airflow. Trying to find that mystery spark retard? Unsure if torque management is causing you problems? Idle tuning got you running in circles? These new tools will help troubleshoot those issues and more!"
:lol:
We're not really worried about that sort of thing, it's bound to happen.

EFILive rules the world, he he he (...powertripping...) :twisted:Originally Posted by GMPX
My outlook on the whole thing is "turnabout is fair play", if you know what I mean. 8)
If I'm not mistaken, it's possible to run 2 bar S.D. on the current software, w/o the need for an expensive upgrade... why don't you folks push that a little more, or maybe make some advertisements highlighting the differences between this software and other packages?
