Attaching log and tune files. Why no PE with the settings I Have? Look at frames 6000-6100. I am exceeding all settings for enabling PE yet 14.68 is still being commanded. What do I have wrong?...

I have a 2012 V8 Colorado with E67. No OS upgrades available for my truck either. When I sent HPT an email asking why, the response was "too much time and money." I don't see why custom OS for E67...
I suppose it could, if you put a VVT cam, phaser and sensor in it. All the tables are there, just needs to be enabled.

When I disabled my MAF without unplugging it, I could see in my logs that MAF was still influencing AFRs, lean during part throttle acceleration and rich at full throttle. When I unplugged...
Took nine months for my "emergency save" stock tune to get uploaded. Good thing I never needed to access it!
Yeah, they only made around 700 a year, 2009-12. Most people who see my truck for the first time are surprised when I tell them it's a factory V8. Then they really flip when I tell them I turbo'd it!...
Here are a couple tunes from before my turbo days. The later one may have a few tweaks to original TM mods, but not sure cuz I didn't look at them before posting.

Looking at this while on lunch break. Once I get home tonight I will post my tune. @AWEBB it is not a I-5 tune, it is a 5.3 tune E67 pcm.
I set dynamic airflow disable to 6500rpm, re-enable to 6400rpm and MAF frequency fail to 0. Also set P0101, P0102, P0103 to 0.
MAF still has influence over AFRs for some reason, even with these...
I banged my head against the wall with this issue also. Finally realized that the MAF sensor was the culprit. Just really difficult to tune blowing thru the MAF. I disabled MAF and now run solely on...
Today I regapped all my plugs to .028-.030. All the plugs looked good, white insulators. clean ground strap and tip. Misfire is still bad as ever. So I have removed the exhaust pipe from Bank 1 side...
So I logged both current and history misfire and neither seems to correspond with the spikes I see in my Bank 1 O2. Are the misfires not being detected? Spark blowout? Last log with misfire history...
Got it. I loaded the table with current misfire for each cylinder but that was difficult to follow. So I loaded history misfire tonight. Will log tomorrow and see what it shows.
It did show some...
I have the stock coils on the truck. I've read the stock truck coils are plenty strong so I never upgraded.
I guess I'll pull the Bank 1 plugs first and regap them to .030. Is there a way to log...
Hey Sultan! Trying to get the tune on my turbo straightened out! I logged after swapping coils from side to side. Still acting strange on bank 1. My plugs are Weapon X heat range 6 gapped .035. Plug...
Around frame 11800 in the enclosed log, my bank 1 O2 sensor goes crazy while bank 2 stays static. Can someone guess at what is happening here? Misfire? Exhaust leak? Weak coil? I swapped coils from...
I've modified my VVT tables based on some old school dyno graphs. The graphs showed power with a 4* advanced cam vs a 4* retarded cam. The graphs crossed around 4000rpm with the advanced cam stronger...
The bluecat tool really isn't very difficult to use. It was intimidating at first, but once you get the hang of it it's pretty straightforward. And it works really well!
Can someone explain the cause of this? Frames 2900-2950 left bank O2 sensor spikes down several times and AFRs go up. I'm thinking it might be an exhaust leak near the sensor. Sounds like I have a...
Thanks for the response. I figured I was on the right track based on what my wideband was telling me. My PE is pretty much activated by kpa rather than by rpm now. Looks like it's working just how I...
So I put delay RPM at 0 and enable RPM at 2000. Enable MAP at 75. Seems to be working well.
Still don't understand why most of the tunes I've looked at are doing this in reverse. Can someone...
I'm trying to figure out which of these settings to use to enable PE. I have looked at some tunes in the repository and most have PE Enable RPM set very low and PE Delay RPM set to where they want PE...
I have the same problem as RichJ. Part throttle has very erratic trims with turbo. Is Dynamic Airflow>High RPM Disable set above 6000 RPM the way to use VE exclusively? Or do I set VE Correction...
This has probably been asked a thousand times, but I couldn't find any firm answers when I searched. Why are VCM Enhancements not available for my 2012 V8 Colorado E67?
I'm struggling with all the...
I was attempting to get my VE dialed in a couple days ago using Bluecat's tool. I disabled MAF and went for a drive to log data. I soon noticed that there was no PE kicking in. Do I have to adjust VE...
