The user-adjustable boost level at various RPM is very very interesting. My complaint with previous Procede versions was that it had too much torque (for me) at low revs, thus altering the character of the engine in a way that I didn't personally care for.

Presumably there is a direct relationship between the boost level and torque output, so the user can specify a milder torque curve at lower RPMs, and perhaps a higher boost at higher RPMs, especially if he has access to 93 octane gas.

I'm also thinking that boost settings for RPMs below 1500 and over 7000 are largely irrelevant?

Now to wait for the user reviews...

shiv i dont know if you'll read this or even care, but manas gowd sent me an important email and i replied asap but he hasnt responded back yet

Actually, what I would like to see is when I press the traction control switch, the system is FULL on I always activate level one of the traction control anyway when I want to play.

I think this would work well also.

As mentioned earlier, here are screen shots of the beta v2 software (inaccurately named v1.02 for now). It offers the following user-tunable features:

-User adjustable valet RPM switch
-User definable boost/torque curve

The RPM switch dictates the engine speed, that must be reached within 2 seconds of engine start-up, to active the performance map. Unless this engine speed is reached (through a simple throttle blip), the PROcede will induce a stock map. This feature can effectively be removed by setting the RPM switch to 0RPM.

Previously, and I apoligizes if I incorrectly read it, I thought you mentioned the user settable RPM switch wouldn't be out until V2.1. Has this changed or was I incorrect in what I previously read?

And no torque reduction for me, 93 octane, no valet ever and a wife who can easily handle a manual transmission 350+ RWHP vehicle.

I never thought people would have so many issues with revving their engines to 1800 to flip the thing on...

So far everything sounds good, keep the updates rolling.

[badass335]

Another little thing to throw in the mix... Running the boost at 100% all the time.. Is this going to give us higher oil temperatures as well. I know a few of us don't have the second oil cooler. Just curious if this is going to throw us into limp mode more and should we bite it and get it installed even at our cost....

[OpenFlash]

There is a boost decay feature that drops max boost target the longer you stay on boost. It constantly monitors the average boost during the last 5 minutes to determine if sustained thermal loading is too high. If it is, it will decay boost until it gets back in check. We designed this feature primarily for road racers and those without oil coolers.

Shiv

so the procede v2 default tune is too agressive to be run hard for a long duration, like on the track... and it had to dial itself back to keep things "in check" ?

correct me if I am wrong

[Serjames]

Shiv, would this mean constant autobahn top speeds will induce a boost reduction .i.e reduction in power, or does the boost issue only really arise on hard aceleration ?

[Dascamel]

On the track a "stock" car with 2nd oil cooler has temperature issues also so don't get too excited.

IDEA: Integrate Proceed functions into IDRIVE

Boost is only generated during acceleration. So cruising at say 120mph wont induce any boost target reduction. Cruising at 150, however, does require sustained boost. And as such, peak boost target will fall over time. Fortunately, you only need 5-6psi to cruise at 150mph.

Shiv

[Serjames]

Thanks for the clarification Shiv, I had a hunch boost wasn't such a factor once you're up to speed.

iDrive, that would be superb...

OT: I assume then that no-one has managed to hack the Nav software ?

Otherwise this would be the perfect way to interface with the Procede.

I love it all... Max boost para me

[badass335]

Well appreciated, my brown brother!

Thank you sir. I needed that.

Shiv

And where, may I ask, is such a thing possible?

[Cadence]

Shiv,

Can you give V1.47 users an idea of where the user-tuneable power level would need to be set to exceed the V1.47 power map?

As an example, if one was to set all RPM points to 85% would this equal a V1.47 map or would it be more like 95%, or...?

Since most of us won't do back-to-back dynos of the V1.47 vs the V2 upgrade it would be nice to know what settings we need to at least equal the power we had pre-V2 upgrade without having to rely on a butt dyno

Thanks for all your efforts

[DrDomer]

Would in your opinion V2 be a "superior" tune for reliability purposes than previous versions, or is it just a performance upgrade?

[Driver32503]

Hey Shiv,

Have you done any extensive tests with the V2 on XI platforms? Can the drivetrain, in the most reliable sense, take all the power available in the user defined boost settings? Also, just some brain candy - manual/electronic override for AWD, and user defined torque split.

Have you experienced any bad things with this product at all?
Especially with XI, since I have a E92 335xi on order.

I had a VW R32 with a tune from APR/Revo. How different will reliability issues be with this different system technology?

-Thanks

Shiv

Shiv, does your decay logic for the above factor in actual temp? i.e. will the decay be less for a car with a factory oil cooler than for a car without the oil cooler?


Thanks.
