    123gr, the Tuning School book is a very good way to get the trans dialed in. They are also very helpful if you need to call them after you get the book. They can help you tweak it to your liking....

    Hello I am sorry, didn't get back to this. I was out for a bit. Lost a family member to COVID-19.

    I have this in the wrong area. Should have posted this in the scanner section.

    Thanks, I will give it a try. I am sure the converter isn't chugging. It sets a temp engine misfire. I have the converter locked up pretty good right there and it is a 6 speed. It is something that...

    c20, I have a similar issue with a 2016 L83 in a GMC Sierra. I am pretty sure I have a bad coil pack. Though mine only has 44,000 miles on it, there have been a few intermittent failures of coil...

    Thanks James! I appreciate your not giving up on me. I will get the vehicle in here ASAP and load it in.

    Update: It is acting differently now that is for sure. It was running good. Suddenly at full throttle second gear, it went into REP at 4000 rpm. It seems to be getting random. Full throttle may or...

    OK I have a positive update. I made the changes below. It runs great good power, trims are right on. It will only give me 96.5% throttle however. I am not to sure that is a problem! It is strong. The...

    You went after that stray voltage that's for sure! Usually it is the Dashboard information system of some sort. Glad you got it going!

    This can be due to stray voltage from accessories hooked up to the wrong spots or, just voltage drops in general like an open door or anything that might draw current while the write process is...

    Awesome! Hope it turns into a long term fix for you.

    Frost, it is a Nick Williams 102. I am pretty sure it was silver. Are you thinking of the LSIII Throttle Body? It would be great to get this thing to run in WOT. It runs so well every where else....

    I also noticed I did not have these settings modified.

    LSxpwrdZ James, I put the tune in last night and sent it out for a run. It is improved but still going into REP. It was able to make a few good pulls at WOT but goes into REP at 5800 to 6000 at WOT....

    Your Idle Base Spark should more closely match your main spark table. I have heard that if your timing tables don't somewhat match, it can cause the corrections to fluctuate. I always try to make...

    When you look at the O2 sensors and the timing, you can see it flatten out once and a while. It is almost acting like a loose connection.105648

    Take a look at ECM] 12621 - IAT Spark Advance Correction. When I look at your scan you are idling in the area where it is adding Neg timing. That only accounts for a few degrees of the timing retard...

    Leva, that is really odd the way the timing and consequently the O2 voltage is sea sawing. I took a hard look at your tune and the only thing I could see is you may want to turn off the [ECM] 270 -...

    I am expecting to get the changes by James loaded in the next couple days. I will definitely stay on it. The vehicle is coming back to the garage shortly. I will say if not for the REP "bug", the...

    Your front O2 sensors are always running the show. Without them working properly the fueling will be wrong and a few other things. The timing is one thing the computer is using to try to control the...

    Leva, you may want to start by matching the Start up Idle more closely to the target idle. You are asking for 700 rpm on a warm engine but your start up grid is 650. {[ECM] 33601 - Startup Idle Speed...

    Thanks a ton for looking it over LSxpwrdz! I am hoping to get back on it in the next few days. I noticed the changes you made on the parameters I have control of. I was afraid to set the values on...

    It looks like a fairly stock tune. With a cam I would expect more changes to the idle air. Also if the injectors were changed, no changes seem to have been made to the injector data.
