Where did you get the injector data? I would confirm this is correct first

I can't see the log as I have the old software, but on a different note noticed torque management is completely turned off. Probably want to turn that back on to keep the trans happy if its stock.
...

Where did you get the injector parameters? If from a stock hellcat tune, the parameters will be different due to different fuel pressure (Hellcat runs much higher pressure than the RT 58psi)

Change the units to Celsius and it will make sense. 32F is 0C, each degree C in hysteresis is about 2 deg F.

A 180 thermostat and a proper tune. A stock SRT8 intake is also probably better for the track, as most aftermarket intakes have High IAT's from pulling underhood air.

People on here will ask that...

Can you post a screenshot of the log? I can't view the newer log files

From just looking at the tune it could be Fuel Shutoff:
-Try disabling "Use FSO" in trans tq mgmt and esp tq mgmt. This...

Post the tune and a log so we can review. What fuel are you running? What are the IAT's after intercooler at full boost?

I'd first check for if the exhaust is hitting something under wot or if...

You probably want a rev limiter on there haha. 200-300 rpm above the shift point is good.

For shift firmness changes go to Shift Pressures then Ramp Torque, and try multiplying the 2 far right...

That is good news, you could try shoving a cut piece of leftover intercooler pipe into the bends to support them from collapsing to test it (not the bend in front of the TB of course, don't want it...

I put together a modified version of your engine/trans CAL that should make it a bit better. Review the changes before running of course, and make sure AFR's are still good at WOT (Since sensed MAP...

A couple of things:
-Engine rev limiter should be at least 200rpm above the TCM RPM Limit. Your Engine rev limiter is at 5800rpm, and TCM RPM limit is 6000rpm.
-Raise Torque limits under Trans...

Try this one - be sure to flash both engine and trans cal. If it still shifts at 6k, then I'm not sure what the issue is.

Trans shift points are set at 6800rpm.
Changed torque converter lockup...

I can't see the log file as I have the old software, but yea the tune shouldn't have fast shifts as it's basically stock, but it should shift higher.

It still shifts at 6k? Strange

The downshifting is one gear offset from what you are thinking. For example the 1-2 and the 2-1 are both based on the 1st gear ratio. 2-3 and 3-2 are based on the 2nd gear ratio, etc.

I checked further and your down shift scheduling was wonky as well. Downshifts higher than upshifts. I fixed this as well as the converter unlock rpms. You changed the max shift time value, but it is...

Noticing some things that may fix your issues:

Engine Side:
-Engine rpm limiter is at 6850rpm, you want this ~400rpm above the TCM limit (Currently TCM limit is 7500rpm). Raise the engine rpm...

Whats the quickest anyone has gone on a tune only nag1 in the 1/4? Just Curious how far it can go without a valve body upgrade before it roasts clutches.

Who did the trans tune? All the Ramp torque values are the same for each shift. Strange.

Also torque reduction time is set to 0 seconds, So it's turned off?

Check the changes and try this one

I think your tune needs higher ramp torque values. Thats the main thing that improved mine (I doubled the high end values from the srt cal). Also you have the torque converter locking up in 1st,...

Just ran a 10.7@128mph with a stock NAG1. The 2-3 shift isn't flaring but it takes a bit to complete now. Other shifts are good.

Now the transmission has stopped flaring like you showed. Must have needed to just relearn through daily driving.

Funny enough, my stock transmission turbo 300 has a similar 2-3 and 3-4 slight rpm flare (not audible in the video below though). I just assumed I'm on the edge of what the transmission can handle,...

Yea, I'm only have spark a enabled. Still has the issue sometimes I pictured above. Not sure what causes it.

I have seen similar things before where it pulls way more timing (as pictured in the 1-2) than normal.
It's usually a little blip where timing goes negative during the shift, like the 2-3 and 3-4 a...
