The nice thing about AutuTuning is that it automatically compensates for such changes in conditions/driving characteristics. It will also automatically compensate for changes in:
-meth/water ratio
-nozzle size
-fuel quality
-nozzle designs
-nozzle location
-FMIC efficiency
-etc,.

And it will help prevent those nasty over-aggression conditions that, when coupled with high boost, can crank piston ring lands and require a 10k-15k motor rebuild

I noticed something so weird in this post, looking at the methanol flow it almost looks like that graph is indicating that the methanol flow is going DOWN toward redline. That can't be true though...

Between 6500 and 7000rpm, i've mapped boost to drop to around 13psi. Meth flow will fall accordingly since the max psi setting is 15psi.

And at the onset of meth, there is always a spike in the meth flow signal.

I so totally don't want the meth to work in 1st and 2nd gears (and maybe at 1/2 pressure in 3rd gear)...the main reason why I haven't bought the kit yet.

I guess an LSD would help, but that's out of my budget for now.

Dang, just when I felt I was able to escape this meth habit...

0 - 5 DC flow signal is needed? What engineering unit range BTW? Maybe I'll have an accurate turbine flow meter available and use it.

Shiv - quick question: The prog meth autotune does not REQUIRE a progressive pump controller right? I am assuming autotune only engages when meth = >failsafe point TPS = 100?

with the proceed you can lower the boost in 1st and 2nd to prevent wheel spin ;-)

[creaminz]

this is great...i just need to figure out how to wire my AA meth kit to compensate PROceed Progressive Meth. Once again...PROceed users should buy Vishnu Meth kit for ease of operation

Shiv, what were your min boost on your meth controller? I take it you're running 15 for max..

8psi min, 15psi max. Although I'm probably going to reduce them to 7psi and 13psi accordingly.

Single M7 nozzle at 150psi?

M7 at 200psi with a solenoid (not check valve).

nice, hope I can test this out tommorow

Shiv do you reccomend a larger nozzle than an M7, with upgraded turbos?

Why not?

Eitherway on the procede you can set you power for first and 2nd gear.

For instance my first gear is set at 60% power while 2nd gear is 100%.

I plan to release it either tomorrow or the day after.

Here's how it works:
....

Am I right in understanding the meth Autotune is exactly the same as the 6-16 Autotune except for having an automatic swich to a non-Autotuned map 1 when there is no meth flow?

Can map 1 be defined for Autotune as well?

It seems quite important that the initial boost is set as near the max expected boost as possible since it takes almost 20 WOT pulls to climb from 14 to 17+ PSI.

[Ferre86]

Just pure great! Please gif!

[ericsmc83]

Been waiting for this! Hope we get lucky and it's released today. Lots of freeway driving for me later! *fingers crossed*

[dzenno]

Track tomorrow, please have this out today

Please let us know how that goes wondering if boging might accure. Also is there a fast way to switch auto tune on for map1 and stop progressive auto tune? Well I guess I can just stop being lazy and auto tune map 1 now before the release.

[mwahlert]

what benefit, specifically in our application, does the solenoid provide?

On progressive meth mode, it's more accurate to not think that there are two maps. Just 2 independent settings that define the aggression ranges between no-meth and full-meth flow conditions. So since autotuning only works under load (when meth is flowing), it should only update the settings that apply under those conditions (map2).

But I know what you are saying. ie, if meth runs out (or is purposely disabled), you still want map1 to be able to autotune. We will work that about by allowing the user to change injection modes (future use 1 settings) without the need of a laptop.

So if you just want to run on pump gas, you will be able to effectively set injection mode to standard (future use 1=0) and be one your autotunin' way. I think that works out better than have both map1 and map2 autotune itself simultaneously which could lead to issues/unnecessary complexities.

Got some testing to do today. Hopefully I will be able to release the new firmware tonight. If not, it will be tomorrow.

Cheers,
Shiv

Using a solenoid (instead of check valve) improves max flow rate as well provides more control when turning on/off the meth. The latter being especialy important since want minimal over-run at throttle lift. Otherwise misfire occurs.

Yep, for the sake of demonstration, I set my meth map initial boost setting to just 13.5psi. Which is ridiculously low for on-meth and required autotuning to raise boost a whopping 4psi. Setting it to a more reasonable setting of say, 16.5psi would have required 1/4th the number of autotuning runs to reach the aggression target. But after after point, the autotuned corrections are persistent (ie, don't reset when you turn off/on your car). To reset them, all u need to do is a dtc mapswitch.
