2016 Hellcat tune and data log

[TURBOSILVERADO11]

I need some advice and opinions on a hellcat. It's a 2016 with a 2.85 pulley, Jlt intake, blower spacers, gutted cats. It still has stock injectors, I know it's stupid it has stock injectors with a 2.85 pulley, but it already had the pulley when it was bought. We have id1300 injectors but they have not been put in yet. I'm trying to figure out why when you leave the line at the track it pulls all of the timing down low in first gear. There's not any knock in first gear, so I don't know why its pulling all of the timing. Is it not getting enough fuel down low in 1st?

Here's a data log from the other night, it did get some short term knock in second. I know the injector duty cycle is very high in some parts of the run.

Here's the engine tune. Thanks for the help, I'm use to gm stuff, seems like it's much easier then this dodge stuff

You need to log aircharge so you know where you are in the timing table. But based on the MAP pressure you should be in this area of the table highlighted in the screen shot. So what you're seeing in the log looks like what's being commanded.

I'll have to check im on my phone right now, but I'm pretty sure I logged aircharge. That data log was the first time I used the mpvi 3 to standalone data log instead of data logging with my mpvi pro hooked up to the computer, so maybe I didn't have all my channels on on the mpvi3. Do you think it would be fine to add maybe 5 or 6 degrees of timing in that area where it hits zero? I don't want to throw to much to quick and make it knock.

I was thinking the last time Iast time I looked at the aircharge in a data log it was showing in the timing table it should be getting 7 degrees of timing where it had zero.

Only thing you're logging for aircharge is aircharge temp. That's not what you want.

As for how much you can add at that point, that's a lot of load down low. There's a reason the timing is pulled down that low. If you add any, proceed with caution. At that RPM, load, etc. too much cyl. pressure will cause real damage. Not just knock but bearings, wrist pins, bent connecting rods, etc.

I added aircharge to the list, but cylinder air mass reads identical to aircharge.

I meant to say in the original post I didn't tune it, and I haven't changed anything in the tune. Is there anything that looks out of whack in the tune? I'll post the trans tune later tonight. Transmission tune is supposed to be stock, I just want to make sure because the tcm already unlocked when the car was bought
