I probably am just missing something. However, When I use the 7.4 version of the scan tool, I can see the FTC information under the tab. When I used the 7.5 version, it is grayed out, and...

I have a V1. I just went and checked it out again. It hovers in the 14.4-14.5 range at most engine speeds in closed loop on the LM1 screen. However, the reading in Efilive is around 14.0. Thanks.

I have a couple of questions that hopefully someone can help me sort out. I have an LM1 hooked up to log with Efilive. I added an additional bung right next to the front stock 02 sensor. When I...

Thanks for the help. Now I know what to look for. MoT

Will the EFI live software/hardware work with a tablet computer running Windows mobile? Thanks.

If I understand some earlier posts, the LTFT's are added to the PE fueling, if they are positive. Wouldn't lowering your switch points also lower the LTFT for that same range? Does this affect the...

You can zero the b6614. The results on the 2006 models is inverse of the previous ones, as best I can tell. I maxed out the b6612 a couple of days ago. It doesn't appear to have any issues. I...

Do you usually adjust B6612, ETC Pedal torque Limit Reduction? I have made a small adjustment, but wonder If I could max it out, if I don't want any reduction. By the way, if you go to low on the...

I have done the same thing to my 2006 2500hd. I have never pin pointed it to the exact table changed. However, the last time I did it, I made some changes to the torque management, traction...

I tried flashing back to the 2005 OS. I ended up with the same problem. I kept getting a lost communications with the TAC code. There must be something somewhat different on the TAC system on...

Do you think it was a boost related problem? I am not running any forced induction yet. I am just trying to learn as much tuning stuff as I can, before taking the boosted leap. Thanks.

After researching it a little more, I bet your ETC problem was in the tables. The 2006 tables I have are 25%-35% lower than the 2005 tables. Both tables apply to a 6.0 2500hd. I bet this much...

Thanks for the reply. I did notice that the tune file is slightly smaller on the 2005 vs. 2006 OS, 753kb vs 773kb. I am not sure what is missing.

I have a 2006 2500hd 6.0 with 12587811 OS. I know that there is not a COS for this number. However, there is a COS for a 2005 OS 12592618. This operating system was used on the same configuration...

Thank you for the help. I am looking forward to them. Mo

Any idea on when the DMA pids and/or custom operating system will be supported? Thanks, Mo

What effect do b3334, b3335, and b3336 have on DFCO, when it is enabled? Can you play with these to gain a little more DFCO active time? Thanks, Mo.

I follow what you are saying. How do you bring your actual vs displayed voltages in line? Thanks, Mo

I have searched and am still not sure how I need to go about bringing my LM1 reading and EFI readings in line. I have checked the voltage at the 3 prong EFI live connector. With the sensor loose,...

Thanks for the thoughts. I did not ever tune it in speed density. I added a couple of degrees of timing down low, and tried to remove the torque management. Could it be something in torque...

I have been doing some basic tuning on a 8.1L with the Allison. I have only worked on the the PCM side. Basically, I played with the timing and burst knock. I also tried to eliminate torque...

I was starting to think maybe I was crazy. I have survived the auto ve and maf tuning. I am now trying to master the timing. I was wanting to log the burst knock pid. Custom operating support...

I tried to log the GM.EST pids for spark today. For some reason they show as not-supported on my 2006 2500hd. It has the 12587811 operating system. I can not swear to it, but I think they were...

If I understand correctly, I need to do the following to accomplish the MAF tuning.

1. Disable the LTFT's and STFT's
2. Remove a NB to place the WB in it's place.
3. Disable the DTC (MIL) for...

So, once you disable the NB, you just pull it out and leave it plugged in to the harness while you use the bung for the WB? Thanks.
