will this also automatically adjust other things like WG duty cycle/fuel and such for folks with upgraded turbos? Or will there just be a "turbo upgrade" version of the autotune enabled map?

Damn Shiv...keep it coming!!! I can't wait! Hopefully within the next few weeks most all of the new PROcede goodies (launch control, in dash boost display, etc., to compliment the autotuning...which will be one of the best features ever for PROcede users) come out, just in time for this awesome weather we are having!

Cheers

Hi Folks,

I want to make sure this isn't lost in all the noise ... what Shiv just demo'd was a dramatic change to the environment. Going from 91-octane piss to effectively 100-octane and back to 91-octane in a matter of a few seconds and the Proceed adapting its tune 3 times in a matter of a few seconds of WOT.

That should be seen as incredibly impressive!!

Most environmental changes are more slight and over longer periods of time.

Most hardware changes to the car are dramatic and over an instant period of time (its installed or not installed). 7 seconds of WOT and you're done? Amazing.

It would be nice to see the old firmware, old maps and tweaked user settings logged for a particular stretch of road. Then compare those results of the new auto-tune over the same stretch of road. If its get to the same point with no user interaction, that's proof that it knows (and most likely knows better than the human).

Just my thoughts,

Junk

Very very cool...would be nice if there was a way to "reset" aggressiveness back to default at user's demand (hit some button somewhere) so that we could on-demand reset it to default aggressiveness when we run out of race gas (fill up at the pump) and don't want procede to take 3-4 runs with knock (ensure as knock-free as possible)...yes?

Hi Dzenno,

Not to answer for Shiv, but it will not take any "runs" with knock to adjust. If it pings even once, adjustments are made ... the Proceed have been doing that from the beginning. The recent v4 does it even better. The auto-tune I think builds on top of the base v4 enhancements.

Not to put words in his mouth, but I think he asked if it will have to learn each time to adjust up or will it "remember" what it has already learned before as a baseline adjusting only if conditions allow, so you are not starting at zero each time you restart the car and having to pull 7 sec WOTs for it to learn. Think of it as an enhansed AT behavior where it learns your style, and remembers it, but now it allows you to say what you wish for so it will target your wishes. Your Wish, my command Jinnie.

I just talked to Shiv and know the answer to vase330, but will it will be better if Shiv answers (but you will be happy with what he'll say).

I had the same concerns too.

Here is a scenario:

1) Get in the car, 91 octane in the car, proceed auto-tuned to 6, head for track
2) At the track, turn car off, load up with MS109 and/or meth
3) After 3-4 WOT runs proceed learns and auto-tunes for 0 but this doesn't induce any knock as we're adding higher octane (maybe proceed hits a ceiling, notices knock, and says ok i'm good here, probably at 0 aggresiveness know).
4) Have fun at the track with race gas
5) Leave track and head to the gas station to get some pump gas to get home. At this point in time procede's autotune is still at ZERO. I fill up with 91, restart the car.

NOW: What I think will happen if I WOT after fill up is that aggresiveness will still be 0 but due to knock it will start ramping up again to 6-7 and once no knock it will stop. If this is the case, I'd like to be able to just reset using a dashboard/steering wheel button/gas pedal/whatever, after I fill up with 91 so that auto-tune is back to 6-7 right away so there's no need to have the engine KNOCK ITSELF BACK to 6-7 through a series of WOT runs. Let me know if I misunderstood....

Remember that the demo log on the first page showed a tune with 0% ignition correction. This is basically a race gas only tune. I just ran it on 91oct just to demonstrate the Procede's ability to determine tune aggression. This has NOTHING to do with knocking a few times during the learning process. Although it is easy to mistake the two concepts.

In reality, the tune will start off with the standard ignition correct you chose. That will either the be the default value (100%) or a reduced value if you want to start off with a more aggressive tune for those. As you drive the car hard, the Procede will then determine if the tune can be made more aggressive by recognizing the absence of knock retard. And will gradually make the tune more aggressive until it achieves the desired level of aggression. This will only take several seconds of WOT. And as the day gets warmer or the harder you drive, it will further adjust the tune to stay at the aggression target.

The only time you will run into serious and consistent knock retard is if your starting point is 0% ignition correction (as set in the user adjustables). Then the Procede will have to gradually increase that value until it hits the desired aggression level. But even that is not the end of the world as there are tunes that run at 0% ignition correction all the time. And all they seem to sacrifice is consistency and response.

See above.

Chances are that you will turn off your car when you are filling back up with 91oct. If so, the learned ignition and boost offsets will zero out and you will be back to your standard ignition correction and user torque values.

How does the meth flow signal figure into the equation? Will it need to be used at all any more?

I would still like to be able to switch between 3 maps/ aggressive levels.

Map 0 Stock - my winter and snow map.
Map 1 Summer Daily driving - set less aggressive and takes longer to learn but is more stable.
Map 2 Track/Autocrossing - I don't always have time to do WOT before autocrossing for the PROcede to learn. It would be nice to start at a more aggressive level just by using the DTC button like I do now. I would find this useful when I wanted to switch between meth and no meth on the fly. Instead of having to WOT a few times before getting the max benefit out of the meth.

Good work, Shiv. Glad to see the PROcede come all this way.

No problem. You will be able to set aggression target individually between map1 and map2. Same goes for starting ignition correction and starting UT. Of course, you can always toggle back to valet as usual.

Oh yes, it's still used. When in progressive methanol mode, the auto-tuning system will only apply to map 2. Hard to explain but if you think about it, it will make sense

Debug Byte 6 is just the reading of how aggressive the active tune is at any given time in any given condition. You don't want this to be persistent because it's only a reading, not a setting.

The Procede reads this value and then adjusts boost and ignition correction to keep this aggression value at the target level (not too aggressive, not too conservative, but just right). It would be easy to make these learned boost/timing offsets persistent. But I don't think you'd want that given the speed at which the Procede learns.

Sounds good. In truth, I don't think fuel trims are persistent either as they adapt rather quickly.

Just thinking of my situation now as my new office building is only five miles from my house and mostly over 35 MPH roads. No time to adapt as I rarely have the option to get on it.
