Doesn't matter - you have to use old software thanks to epa bs to disable that kind of stuff now. There's a post O2 test and cat test both that will cause fueling to get stuck if sensors missing. If your able to disable those test then your good to go.
2010 Vette Stock Bottom LS3 - LS2 APS Twin Turbo Kit, Trick Flow Heads and Custom Cam - 12psi - 714rwhp and 820rwtq / 100hp Nitrous Shot starting at 3000 rpms - 948rwhp and 1044rwtq still on 93
2011 Vette Cam Only Internal Mod in stock LS3 -- YSI @ 18psi - 811rwhp on 93 / 926rwhp on E60 & 1008rwhp with a 50 shot of nitrous all through a 6L80

Post-cat O2's don't control fueling like the fronts do, but during the cat test it makes it go rich and looks for a response from the post-cat sensors.
It looks the same but its not...
Here is a drive log. Hjtrbo i did not add in the flex fuel spark changes you have given me yet because i have pulled timing from the whole table until i can verify fueling with a wideband. i know on the dyno my car did not like more than 19 degreee timing on gas so i will adjust that accordingly. So this is just a log with the same settings as last time but just a quick drive and not just idle.
Three things bug me.
1. IFR is still pretty high and for some reason. I double checked all the injector data and it seems to be correct for the id1050x injectors. Maybe i am missing something easy.
2. Fuel pump duty cycle command is 99 percent. The tune looks like it should be 90% until 5000rpms and then ramp up and not hit 99percent until 7000rpms. Can anyone see why it is doing this
3. LTFT Min ECT is set to 172 stock is like 95. Is this a big deal?
quick drive with some changes.hpl
as found with iat multiplier fixed plus rev changes minus timing.hpt
Our setups are slightly different. I've added a better scanner list for you. Load that up next time you go for a run.
IFR is fine. What you see there is you have an injector delta pressure of 400kpa. If we look that up on your IFR table with the multiplier that's right at 14.5ish g/s.
The fuel pump duty cycle. We need to see the FPCM tune for that. You'll have to license it and read it out. Now on that, I'm not sure if its a virtual read (used to be in the past) or if HP does an actual read now. When you read it we should be able work out if its actual vs virtual by doing a stock compare and / or analysing the log.
LTFT min ECT. Up to you really. What's happening there is that the original tuner doesn't want the long terms updated until the engine has settled at operating temp. Everyone will have different takes on this. Would need to see a log of a freezing cold to hot long ass idle. Can look at the trims over the 10minutes and see what they're doing. If a little off then can use ITT table to add / remove fuel when injectors are cold.
Your idle spark is hovering around 0 deg. Should be up at 15 as per your idle table. Min air flow looks ok. You standard throttle body?
6 x 12hr shifts yuck! Hope they give you plenty of time off. Pretty common 12hr shift here in Oz is 4 days on 4 off. Some of the really lucky ones get 4 on 6 off!
yeah definitely do that. I remember when i was in my early 20s (fresh out of school) i had one goal...to make as MUCH money as possible..lmao. Over the years and now having a family my views have definitely changed on that. Well, I'm hoping for your sake that time comes sooner than later for ya
Be random and move to Australia mate. A good Mech or Elec trade can pull easy $140k/yr base + overtime (at double time) + 10.5% superannuation working in a manufacturing / production facility doing 4 on 4 off shifts, not even breaking a sweat or the relationship. Free healthcare over here too. And you can trade your ZL1 in to buy a Holden . Gas is a bit more expensive though, and so is beer, god damn it. E85 is USD$5.18/gallon. Beer is USD$32 for a 24 pack of your local favourite brew. 2 bits of nice porterhouse from the supermarket runs around USD$11/lb.
Finally got my wideband installed. I was able to do a quick drive. Man this was lean under power enrichment.
Here is the first drive with i didnt load your list yet i will do that tomorrow. I just wanted to get a quick log real fast.
step 1 maf wb.hpl
this is the tune that goes with it.
15zl1 maf tuning trims only step2.hpt
these are the adjustments i made.. I know i am a long way off just wanted to get started and see how it reacts. tomorrow i will do some more logging and maybe start putting the timing set up you gave me in.
15zl1 maf tuning trims only step3.hpt
Latest data log and tune changes after data log.
step 3.hpl
15zl1 maf tuning trims only step5.hpt
Still pretty lean up top
Changed where i had injector tip temp set to add. i noticed the stock set up i was already in the adder just driving around normal. few changes to maf and I am getting closer.
15zl1 maf tuning trims only step6.hpt
step4.hpl
hjtrbo I would love it if you looked over this stuff to see if it is set up properly.
Quick run. I am pretty sure it should be in blended air mode. I have two logs but for some reason one of them will not upload
15zl1 maf tuning trims only step16 w dynamic air.hpt
vve and maf1.5.hpl
Also two graphs i am using to fill out my VVE one with fuel trims and one with WB
VVE wb.Table.xml
VVE ft.Table.xml
Lastly the math I am using thanks to this thread. https://forum.hptuners.com/showthrea...ation-for-gen4
gmve ft.MathParameter.xml
gmve from wb.MathParameter.xml
Just need to set min max ECT for maf fail to stock and also P066 airflow correlation.

Your filters didn't work. Use these
Fuel trim
[6215.241]<60 and [2517.161.avg(500)]=0 and [2517.161.avg(-500)]=0 and (abs([50090.156.slope(1500)])+abs([50090.156.slope(-500)]))<2 and ([6310]=7 OR [6310]=9 OR [6310]=14 OR [6310]=15)=0
Open loop WOT
[6215.241]<60 and [2517.161.avg(200)]=0 and [2517.161.avg(-200)]=0 and[6310.avg(1000)]=9 and [50090.156]>98
Maths is fine for closed loop. Didn't check open loop as you had not WOT runs in there.
