I am installing the LS2 Silver plate DBW throttle body on my 2001 Yukon XL 2500 in place of the 3 bolt 78mm tb. I have the adapter harness converting to single 6 terminal connector along with the...

Thanks 2xLS1 I will look at that and see if I can reassign it. Recirculation is important in Florida so may have to think a little about that Though. Will try my a/c without recirc. For a few days to...

I have a 2001 Yukon XL with the Red and Blue connector PCM and added electric cooling fans controlled by the PCM. I inserted a wire in terminal 42 of connector C1 (Blue) for the control of one of the...

RonSSnova Thanks made the changes you had and it starts much better. Just need to play a little more to get it where it needs to be. Thanks for the help

I have an issue where the throttle dips from 70% down to 50% in the middle of an acceleration without a peddle position change. It dips and returns quickly. No wheel spin for traction control. Can...

RonSSnova thanks for your reply. it runs really lean and stalls first restart even second restart before it stays running. Then reports 16 to 1 and idles very rough. I just upped the afterstart...

MikeOD thank you that fixed the issue thanks I learned something new and appreciate the help. Now read 40's on the PID where it didn't before. How do I remove the MAF from the tune or is it necessary...

I'm having an issue with the timing it does not follow the main spark tables. I have zeroed out the IAT, AFR and ECT spark correction tables. It seems that something is retarding the timing and...

I need some help with restarting hot. When restarting it goes real lean for about 1 minute or until the fuel trims take over and add a bunch of fuel. It will eventually settle in and the trims stay...

Thanks mowton it did so far. I thought about scaling the tune but was not able to find enough information on exactly which tables to scale so opted for the sd. If you have a link to a post with the...

Thanks for all the help. Changing the MAF failure to 13,500 fixed the issue the only problem was that I now exceeded the 512 g/sec so I Decided on the SD tune as. Removed the extra pids which helped...

I have a 2001 LQ4 in a 2001 Yukon XL, When I start it after setting while still hot it will run lean than rich and continue oscillating until it has run for 4 to 5 minutes where it settles in and...

mowton and ranger6202, Thanks for the replies I really appreciate it. I did tune the MAF in a later log this was an earlier log showing the spike I didn't have one later than this one with WOT as I...

Thanks for the reply, I am using a 4"Aluminum tube assembly with the stock MAF so if i add the LS2 MAF how will it keep the MAF readings from exceeding the 12000 range in the table? When it reaches...

Okay maxed out the MAF table running 12000 Plus with a 2300 supercharger on a 6 liter. It's a 2001 DBW 2500 GMC factory 78mm throttle body and factory ECU with HPTuners 2 bar enhanced OS, does...

gagliano7, Thanks for the information. Will pull that and see how it works. Will be doing that Friday.

Just overhauled my 2001 6.0 and went with the 36lb flex fuel injectors I will be scaling them sometime this week or next when I reinstall the engine. will post the file for you once complete. If...

Got it Thanks for the update can't wait to use it.

Your Second tune is actually running in MAF with STFT and LTFT enabled. The MAF is not failed. You have to set the DTC P0103 to MIL on first error in order for it to fail the MAF. Not sure if your...

Can you post a scan with the issue along with config file.

I have the Innovate MTX-L wideband and the wide band gauge reads .2-.3 different than the reading in HPtuners charts while scanning. I have moved the ground, calibrated the O2 again and still the...

Thanks everyone the MAF adjustment did it. Appreciate the help.

My setup is k&n air cleaner setup, cat back exhaust, lysholm 2300 Supercharger, 12lb boost, everything else is stock. Checked for intake vacuum leaks none, runs great except for idle lean. Trims...

I have been trying to figure out why when it comes to an idle the LTFT and STFT both are at maximum and the mixture is extremely lean until they bring it down to 14.8 to 15.0. I am running a MAF tune...
