I didn't say that. This next update is not idrive related. To tell the truth, we haven't even looked into it. Not to say that it isn't possible. But we currently have other fish to fry.

Great concept. I'd def still prefer an actual boost gauge though for the response time & easier visibility.

Our boost display will be user configurable to display a number of parameters. You will be able to scroll through the different options to see what you want to see. In the case of the boost gauge, I will probably be most useful in peak-hold mode. So that it records max boost (to the nearest .145psi) and displays max boost after your run (displayed in bar). Same goes for IAT, active ignition correction (what what?), active use torque (what what what?) and a number of other parameters. It will also become the interface for conventional (non-automatic) user-adjustable tuning so that no laptop (or dyno for that matter) will be necessary to dial in max power (if that is your goal). You basically dial in your values using + and - buttons on the dash.

along with the WG duty cycle learning feature already implemented... for all the many people with upgraded turbos, the procede will pretty much automatically tune itself?

[alextremo]

Please tell me meth activation/flow is one parameter we can see (if using your kit)!!!

Looking foward to the updates!

Wasn't really interested in anything until the last section.

That's hot shit.

I'm pretty happy with it. I should have some more video/info to post towards the end of the week. The reality, as others have pointed out, is that the upper power limits of these cars is largely established regardless of tune. The game has, in my eyes, changed from what tune makes the most power to what tune can make the most power, with the best drivability, with least customer fuss, and with the most flexibility/feature set.

The extra features don't hurt either

[AltecBX]

Shiv, are you saying that the In Dash will display how much torque your're using in real time? What about HP?

[AltecBX]

Ohh, ok. I thought that's what he meant because he said no need to go to dyno.
So this mean that will probably won't need laptop unless for map uploads.

Basically, what we've done is mapped out the DME's ignition advance table (rpm vs. load). And by comparing actual CAN DME ignition advance (from CANbus) to the value in this table, we know the amount of reactive knock retard. And a running average of this value taken during heavy load operation, tells us how aggressive the tune is for the given conditions (fuel quality, ambient tmep, FMIC performance, etc,). By reading this value, we can target a given "aggression" value by having the procede automatically adjust ignition correction. If we reach 0% ignition correction (by running race gas, for instance), the Procede can then start gradually raising boost (user torque) until the desired aggression level is reached. On the other hand, if ignition correction starts to creep upwards and reaches 100% (inadequate fuel/harsh conditions), the Procede will then start to reduce boost until it reaches its desired tune aggression. And these values can be displayed on the screen along with the max boost you want the procede to run during best case (cool conditions, race gas, etc.) scenario.

Basically, the idea is to eliminate the need to datalog and custom tune your Procede for max safe power. It will basically do what you do when you follow the custom tuning guide (looking for ignition advance drop-outs) under boost. Except it will do this 100% of the time and automaticaly adjust the tune accordingly as conditions change. And it will do this better than you ever could do yourself.

And duiring all this time, the DME should never see conditions where it is routinely pulling back timing. Just as it should be and like it was when you were running the stock tune on premium fuel. As far as I know, this is the fist time that boost and ignition advance will be autotuned by any aftermarket tuning system. And it means that you can just plug in your tune and simply forget about it and ALWAYS make the maximum power that your mods/conditions will support if you so choose. It's a pretty big deal.

Damn shiv once again you have outdone yourself this sounds amazing, cant wait to try her out.

[RBC]

Now this is impressive!!!

Not even on my wildest dreams I ever thought we could get this far!

I am simply amazed with V4 capabilities...

IMHO V4 is pulling hard from the competition by adding tremendous useful features day after day that simply make a huge difference by the end of the day.

Congratulations!

Shiv thats amazing I my self find it hard to keep up with you and all these new features
Will it ajust rightaway to different fuel or an extra mod. or will it need some runnig in period ?

The speed of autotuning will depend on how long the knock retard running average period is and the "step" size of the resultant ignition correction/user torque adjustment. We want to keep things slow enough to keep the system stable. But fast enoough to keep the auto tune responsive to changes in fuel, condition, use, etc. Interesting enough, the logic here is nearly identical to closed loop boost control. But now we can call it closed loop Tune control I guess. I'll have some more data and test results (dyno) to post next week illustrating how this works.

It's similar to what goes on in the DME in that it applies long term timing trims. But dissimiliar in that it will also apply long-term boost trims when timing adjustment range is maxed out in either direction.

Im really excited for this stuff coming out. The procede is really the perfect tune for me now. Id much rather have this the way its going to be than a flash. so many different and useful things that come with it. No upgrade fee too is amazing. great job guys

[AltecBX]

Shiv so let me get this right.
With the addition of this feature coming to the PROcede, the Procede will basically tune each car automatically to its maximum power?

Will this eliminate the upload of new maps in the future? Just maybe firmware update for new features?

After the logic is applied, the car will auto-learn on how to adjust each setting automatically and run correctly & 100% maximum power at any given load and condition?

Will this feature work exactly how BMW designed their DME to adapt to better fuel for better performance? Will the Procede make the car act & feel like is naturally making that amount of power from the n54?
I know it feels that way now, but all this sounds like it was designed for commercial use straight out the factory.

On another note, for the technical car guys; Can you come up with a diagram that can illustrate what Shiv wrote here. I want to visualize his description of how it's working.
Here's an example:

But seriously, I'll like to visualize how all this is working.

[stressdoc]

Can other goals, say fuel economy, also be included in the algorithms? This would be especially useful for situations such as cruise control set.

On a different topic, can boost be displayed in the lower/larger display window? Where the average MPH is displayed in the video? I have the active mpg displayed there. That would be easier to see while driving.
