I already have UT = 90% for first gear & UT = 92% for second gear.

...there's just no sense in spraying meth & adding more power in 1st and 2nd gears unless you've got an Xi or an LSD, the latter of which would still probably not hook up w/o power reduction in 1st & 2nd.

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.

OK, and what is the answer to the first question "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? "

[OpenFlash]

New firmware (#16) is posted here: http://vishnutuningforum.com/viewtop...&t=21&p=23#p23

No new maps

Enjoy!

That's basically right. Keep in mind that progressive meth mapping still works the same way that is has always. ie, the more meth flow, the more aggressive the tune gets. When meth flow is at max, the tune will run map2 UT, IC and max boost limit settings. When meth flow is zero, the tune will run map1 UT, IC and max boots limit settings. All the Autotuning does is adjust map2's UT and IC settings to achieve the aggression target. So when there is no meth flow, the tune does not "slide" up towards the clever adaptive map2 settings. Instead, it just stays firmly planted at the static map1 settings.

FWIW, on my fully modded car running an m7 jet at 200psi and on 91oct gas, I'm running the following starting default settings:

Map1
UT=14.5psi (45%)
IC=50%
Max Boost=16psi

Map2
UT=16.5psi (65%)
IC=0%
Max Boost=17.5psi

When driving, map2 settings autotune to around 17-17.5psi. It would probably go higher if I raised by max boost setting. But I'm not too comfortable running much more boost for daily driving purposes. Especially when i'm running 91oct under my meth.

[ericsmc83]

Got a chance to drive the new firmware a little bit tonight. Did a few WOT in 3rd. Had one weird small stutter/hiccup on the 2nd WOT at about 5k RPM (no codes), but feels very strong other than that. Didn't have my laptop with me, but according to the boost gauge, the autotune on meth maxed out boost-wise at least.

Current "daily driver" settings:
Map 1 - Max 15, UT 45, IC 75, AT 2
Map 2 - Max 17, UT 65, IC 25, AT 2

Gonna take the laptop with me tomorrow (might have to hold off til Saturday cuz forecast shows rain next two days) to really see autotune in action.

Thanks for clarifying.

Control question: If injection mode is set to 0, is the functuonality the same as with the previous firmware, where autotune can be active for both maps?

Yes indeed. No changes from previous firmware if running in standard injection mode. All we did in this newest firmware update is activate full autotuning in progressive meth mode.

Let er rip. But once fully learned, there should be absolutely no hiccups or any type of performance aberration. If you do feel any hiccups, make sure it's not your traction control system intervening. When running autotuned meth maps, that often happens in 3rd gear. At the very least, I always drive with my DTC button pushed one (DTC light ON). Allows for a little bit of wheelspin when the foot goes down

[335iPSI]

As a previous 335i owner, I regret selling my car now due to these bada** tunes! I'm in the market for a 335xi coupe which I think would be AWESOME to run this progressive autotune meth map on in 1st gear .

[enrita]

so lets say i have map 2 and meth on.
I switch off meth completely because i dont need it at that specific time. the procede will switch automatically to map 1.
I than swith meth on. Will the procede go back to map 2 without having to switch map with DCT button ?

Shiv if you run 93 would you still recommed the same settings.

Yes, that's pretty much it but think of it as the switch being progressive between both maps depending on the meth flow..........you would only switch maps with DCT button if you wanted to reset the autotuning's learning from scratch.

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

What I would like to see.......
If you set injection to Progressive Meth mode (Future Use = 1-99 meth flow range) it changes the DTC map button to a Meth Injection On/Off button rather than a map switch button..........since in this mode, map switching becomes irrelevant since "Meth Autotune" progressively adjusts the tune depending on meth flow. Basically the DTC button switches between Meth On / Meth Off / Valet Mode.

By Switching to Meth On, a signal is sent through the CANbus line that then outputs 12v via the aux port on the Procede, to a relay. It enables the meth controller, automatically sets Injection mode to Progressive Meth Mode (future use 1= 1-99) and progressively moves between Map1 and 2 with the learned Autotuned meth settings.
Switching it Off, disables the meth controller, reverts to Map1 and to a Normal Injection Mode state(future use 1= 0).

This way, Autotune should be enabled in both injection modes regardless on how it's set.

For those without Meth, they leave Injection Mode set to Standard (Future Use=0) and switch between Map1 / Map2 and Valet........as usual.

Also in the future, once the DTC button switching remains "Autotune" persistant there should be a setting to reset Autotune via the User software so we still have the option to allow our tune to re-learn from scratch if necessary.

This will be great. No additional line for a switch. I recommend this to be used with the hazard button but this method is just as good. The sterring wheel buttons are even better if Shiv can program those in.

-If what you suggested with the dtc button is implemented and not the hazard, then you can use the hazard button to reset the values on the desire maps. So if I'm in map 1 all I have to do is double click on the hazard button to reset the value back to default instead of connecting a laptop.
-Another suggestion, if this can be implemented in the DTC button sequence, is to triple click the DTC button to clear the values.
* One DTC click to engage DTC or disengage the system
* Two DTC click to change maps
* Three DTC click to clear map currently selected (back to desire input values)
* Hold DTC to turn off DSC completely

[ridin135]

shiv since this is tunning map2 should we put map 2 on in the user adjustable and turn map1 autotunning off or does it matter anymore?

It doesn't matter in progressive meth mode. Just leave them both ON at this time.

I'm currently in Germany and the car runs absolutely great on V4 Autotune Vishnu has done an excellent work with the tune.

[AltecBX]

I still haven't installed the Vishnu meth kit. I'll prob get around to it next week now that I know auto tune supports methanol.
Questions
How do I know if I have a solenoid or check valve?
If I leave injection mode to 0, will it operate exactly the same as if I didn't have meth?
Does injection mode have a higher precedence than autotune map1 and 2? (so if a value is entered in injection mode then autotune values are disabled.)
Will you have an on & off meth button so we won't need a laptop as the non meth users have?

[Ferre86]

auto tuning just works perfect when meth is enabled
debugbyte3 gets active = 1
Future use 1 set to = 1
UT = %70
IC = %0
maxboost = 18psi
car is able to push 17.8-17.9psi..
when i switch off meth from the remote control, the car is not auto tuning on map1, 14.2-14.3psi and debugbyte3 does not get active..

map1
UT = %45
IC = %50
maxboost = 16psi

any steps that i would be missing here ..

Thanks,

You break traction in 2nd gear? Interesting. I can't get my car to break traction in 2nd, 1st happens all the time, but not 2nd.

-Vishnu kit has a solenoid
-injection mode 0 = no progressive meth, the meth itself is still active.
-if injection is below your set threshold autotune will not be learning.
-I don't understand this question. Pull the fuse or cut the pump power if you want to disable methanol. Honestly I have no idea why you would want to though.

If you are talking about Vishnu meth kit mine came with a remote key fob which you can use to cut the power from the pump.
