Thats why I said only one is used. I am just a weirdo and make them all match.

To OP like edcmat said you're not even at proper engine temp. Should not even start logging till you're at normal...

Like they said its there to suit flex so if not on flex just set the entire table to 14.7 or some do 14.1 for e10.

I always do even if I know it's dod or not but that might not be your issue.

There are 4 different VVE tables. 1 usually used. I always make same changes to all of them. Are you doing this?

Like alvin said above people add boost to higher compression stock N/A engines all the time. You will be limited on pump gas and especially if you dont up the injectors probably before you have a...

Like edcmat has said have you tried to pull say 4-5* timing out around the 3600rpm and up just to see if it helps with the knock. Might be a bit spicey at max tq even with the octane.

Looking at your high-octane timing map its matching pretty good to your logs. At 5600rpm your tune is commanding 10.50* and your hitting 10* in the log. At 6000rpm your commanding 7* timing in the...

I think the newer e38 dont need scaled but if yours maxes at 63.5 then yes. Double stoich, half the flow rate and IVT tables.

That sucks they have such low octane at 1k feet. Kind of surprising actually.

If you get good injectors like ID's the data is pretty spot on. You might need to slighly adjust VVE and MAF for...

The old seafoam trick. I remember when I was young and tuning peoples DSM's I would do this all the time. My neighbor used to get so mad saying I was destroying the environment. HAHA. Another reason...

I think your overthinking the octane a bit. At high altitude that 91 will be fine. I am guessing you will be in a high-altitude part of AZ if you only will have 91. I've been tuning on 91 all my...

Disable LTFT.

If your fuel trims are way off, you can use the wbo2 error to get them close. Then use fuel trims to dial it in that uses the narrowbands. IMO the best way is just disable LTFT's and use only...

Depends on if the cats are still installed also. IMO on a dyno you should tune closed loop, idle, cruise with narrowbands and then when it comes time to do WOT tuning you remove a narrowband and pop...

The goal is to log via HPtuners so you can setup logging MAF vs AFR error. This way you can just copy past into the MAF table to get the PE dialed in to whatever you set it too. Running the wires...

When you add modifications that adds airflow you need to adjust your VVE and MAF tables. If you change the intake size the MAF needs tuned. I highly recommend learning the basics of how fuel...

Being a novice tuner like yourself I would work off the current tune since most of the drivability stuff is probably pretty good.

Living in high altitude I have seen stock cars swing 10-15% going from 5k altitude to 12k+. Dont chase your tail on the trims. Within 5% is perfectly fine.

Oh, that's not good. Didn't know you could hear the ping. Definingly need to look into fuel delivery. If pump, fuel pressure is good I would think about trying to swap some other injectors over...

Make sure you install GM original sensors. Not aftermarket.

I see your fuel pressure falling off but its still above 50psi which should be okay. Might need more tuning with the AUX pump, I would think that you have enough pump to keep pressure up. I believe...

Thats what they call false or phantom knock like everyone is saying. Do you get knock at WOT? Make sure the exhaust is not hitting anything like frame rails, should be completely suspended by the...

So I noticed this same issue when I adjusted the OL tables when I was having a super rich startup when cold on e85. When I leaned up the OL table I got the lean tip in issue. I richened it backup and...

Why dont you post your exact vehicle, year, mods, log, tune. You literally just posted this with just a download file, no info of what its from and what your issue is.

Race Proven Motorsports posted a new 5th gen ZL1 video. Same issue. So it looks like this is pretty much happening to all these motors. I reached out to Fran the tuner/owner and he said he doesnt...
