How come meth is not 100?
 
How come meth is not 100?

With his flash map his trims were running negative as I recall, so he lowered meth flow to compensate.
 
______________________________
All FSB since the Stinger has existed are V2 models. :) Yes he's using the custom tuning option to tailer his meth flow based on his unique needs.
 
I have dual nozzle 755 cc combined and pump is cranked to 300psi I've been playing with different wmi duties. At 100% duty the trims drop to about 5 (-25+)% with 90/10 wmi. Ran 80% for a while. It was going a little rich at times so 60% seems like a good balance for now. I'll try to increase here shortly.
40% ran slower, 50% faster and settled on 60%.
Using fsb and pwm.

Ooooh that tune is working. If only he'd put a price tag on it. Congrats! Make me wanna take mine out, I just dont wanna have to clean her back up.
People who support us and have bought a previous tune funded the development of stage 2. Free for all of them.

Those who have remained silent and waited patiently $1495.

For those who ran their mouth, didn't believe in us, thought they knew more, $2495 :)

How about those that supported real tuning from the start but didn't have a stinger yet and now they do? ;)

John always assumes people are his enemy.
 
Looks good. More boost didn't help it further? You've got plenty of room to add more meth flow too when you're ready for it.
I was running way more boost a few weeks back but we dialed that back in the tune. I tried to add a little up top with the jb but didn't seem to add any. I didn't try it much and running good as is so left with just the tunes boost. I should test again.

It works, but the snips vary greatly. Many get 1.75 60s and a few get 1.60 60 foots. Mine is a 1.75 60 foot which is about the same as my enhanced LC. Brake snip almost always whacks out my timing so launches good then lose out later.
My snip is 2800 rpm 8 psi.
A 1.60 60 foot has 15 psi brake snip

My lc is 3.5 psi and 2500 rpm and opens throttle faster than snip, thats how it maches the 60 foot with less rpm and boost.
So that’s all a result of your Tork Tune?

I think it is... there may have been some IAT spoofing, but a previous run of no JB4 spoof was 11.46 I think, but we think that was all in the 60 ft time also because the 11.46 has a slower 60 ft time.

Here is the log for the 11.39 1/4 mile.
Mostly 20-21.7 PSI, hit 22 PSI briefly beginning of 3rd. Holding 21 PSI up to 6k RPM in 3rd, 4th and 5th. I think that is where the increased trap speed is coming from. No added Jb4 boost. Ign 2-6 almost perfect single line.
PSI is Jb4 V13, so 18-19.7 PSI equivalent for pre V13 firmware.

I want to step up the ignition and start running E40 :)

That is still very conservative ignition we are running, dial up another 2.5 degrees and another lb of boost up top, and we might have 11.1 - 11.0 in your car. Now process this... we are still running through the factory primary cat converters!!!

The biggest question being... can we run 10's on the stock turbos?

If you are asking about the launch part, yes, 2500 RPM, 3.5 PSI and 1.75 60 foot is all in the tune.

The snip part is cutting the ECU brake wire but the switch is left connected when using LC. The switch prevents normal LC.

So, I stand corrected (thank you tonka) the 11.39 draggy is all tune, no JB4 intervention or help. Also, no brake snip or assistance for LC either. This was all 100% Tork Tune!

No just effect on launch from the tune is what I’m interested in. Personally I’m intrigued with the snip but on the other hand not interested. I’m sure now that we are startling to see more tuners getting into the “Stinger Game” we will see launch times improve with out having to snip. And I think that as soon as the PNW tracks open you’re going to prove it:)
