It's not a layout file. It's a channels list
Your missing a bunch of PID's in your log for it to be useful. Also MAF only won't run as good as speed density, especially with a cam. Not really sure how your adjusting fueling without being able...
That's much better but your O2's look to be reading about 2-4% lean. If it were me, I would set your Bank1/Bank2 tables to 500mv across the board and go for another log. That should give you some...
The ECT vs IAT table looks good/stock to me so no issues there. Do you have your stock tune? If so post it so I can compare a few things.
Looks like your Bank1/Bank2 mv have been played with to...
It's pre-programed into the scanner? Very simple equation.
HP Tuners language: 100 * ([50119.238] - [50118.238]) / [50118.238]
English: 100 * (Actual EQ - Commanded EQ) / Commanded EQ
Something is wrong there. Post the tune you ran with this log
Make sure your logging all the pids your charting. That should be right graphed right
If you disable them you won't have any fuel trim data to read? Enable both of them and get a log with as many cells as you can filled in without going into PE.
Start by correcting your MAF and VVE. There are multiple walkthroughs on this forum and even YouTube that show/teach you how to do it.
I'll even get you started for with some excellent 6L80...
Posting your tune would have been a lot easier and would give people the opportunity to give you a real answer
You can leave it at 14.1 if you want, or change it to 14.7. It won't have any effect
Stoich for gasoline is 14.7 and you tuned it to 13.8 - 14.2 so that's why it's reading rich. Gotta Start using lambda. O2 sensors read in lambda regardless so 1 lambda is stoich no matter what fuel...
Try this out. Just failed the MAF properly and returned timing tables back to stock. Post a log when/if you decide to try it
I'm confused, are you trying to fail the MAF and run in speed density? The PID in your log says the MAF is failed but it's definitely not failed correctly in the tune. You should probably put your...
Can't tell much about the trans with that log but your fuel trims are still 12-15% rich at low RPM/load. You might want to dial in those areas with STFT+LTFT math on both your MAF and VE.
Post your tune and log.
The VE is wrong because it was previously calibrated with low fuel pressure.
Spark tables are almost stock (according to my compare file)
PE settings seem fine to me
There is a wideband in the log
It might seem like bad new but it's actually good news. Your fuel pump is doing it's job now and your extremely rich starting at around 3000 rpm, to the point of your probably washing down your...
The stock table will absolutely be better than the one that was in there. That was terrible. It's just a starting point anyway
Here's your posted tune with the MAF failed and stock 99' silverado 5.3 High/Low octane tables back in place.
When tuning with the MAF failed remember that you'll be referencing the low octane...
Welcome back. Looks like your posted tune is set up correctly for MAF tuning
Correct... I suppose I should be more specific rather than encompass the details in "runs"
You need to add to your logs dynamic airflow, EQ commanded, vehicle speed, just to name a few. Your MAF and VVE need work and it idles rough because your timing goes from 25 degrees down to 4. As...
You won't hurt anything. It's just a preference as long as it runs/drives well
