Looks (from here) like marketing _and_ tuning.

I'm grateful for for the update, and v2.0 looks to be a blowout; but I think you're over-selling this crowd.

Holy Mother of GOD!!! 100rwhp over stock!!

[CaptOz]

With that sort of power increase, what 0-100kph (0-62mph) times could we expect?

So glad I went the PROcede path.

Hi Shiv

Congratulations to this big step. One more time I am very happy to be part of the PROcede community. Keep on the excellent work !

Cheers

Best of luck Shiv.

Shiv, you are the man. It's hard to imagine getting that much power out of this car since it is such a beast already. :rocks: Shiv, btw where can I get a Vishnu window sticker. I think I saw one on some of the other cars on the forum.

Awesome job shiv... These graphs finaly validate all your "talk" about how the PROcede was supirior with its digital I/O's.... my hats off to ya.

For those who forget... this is what shiv said could be done with the PROcede, that could not be done with the XEDE.

2) Speed limiter defeat. Requires the use of both a digital input and output. The input to read the orginal vehicle speed sensor and the output to generate a modified signal based upon the input.

3) Wastegate control. To drive the wastegate solenoids, a pair of inputs/ouputs will also be needed.

4) Timing control. Need both input and output.

So to control all of the above, you will need 4 digital inputs and 4 digital outputs.

PROcede has 4 digital inputs and 4 digital outputs
Xede has 1 digital input and 2 digital outputs last I checked.

Taken from this flam... er, I mean, post http://www.e90post.com/forums/showpo...&postcount=156

Congrats shiv, and keep up the good work!


My v2 predictions...
VANOS control, raised speed limiters, and gear dependant closed loop boost control... along with encrypted maps and firmware, and new pc software to support all the updating.

All this will require is a few extra wires to pop into your harness, and some updates via the serial port.

What about longevity, and reliability. I want as much power as the next guy, but not so much that it lessens the life of a 50K car.

Again, I am not bashing as PROcede will be on my car, I am just curious at what pont is too much?

Anybody have some BMW insider info on what the 335 can handle without making it un-reliable or losing its longevity?

Well it's common sense that if you add more power and torque...you'll cause more wear and tear on your engine, and trans..but this car is too new for us to study...
but if the N54 is anything like the 2JZGTE, then you've got nothing to worry about...

there's a saying..."If you can't handle the heat, stay out of the kitchen"

You gotta pay to play...

According to Shiv, he's going to dial back the finished product to not induce excessive stress on the drivetrain. Sounds like the threshold of the pain the car can handle may be getting close.

[scottp999]

So will version 2 + exhaust be called stage 2? Great work. I still would like to know your current in-stock levels and/or wait times for the exhaust system.

Thanks.

The gear dependant boost control.
I dont see how this would be possible, without another wire for the PROcede to detect gears

all they have to monitor is speed and RPM, they dont need an input for detecting gears... the PROcede has everything they need to do this

Yeah but still. If a car is putting out more or less power then the PROcede specified, say 100 more horsepower (Just an example) the table the PROcede runs off of would be very off.

Great announcement, but if you think Shiv is doing something BMW has not in their own testing and racing programs...muy loco!

Shiv...

Have you been data logging EGT at each cylinder? Can you shed some public light on the BMW development team's observation of high EGT's under higher boosts, particularly Cylinder 5 and 6?

Terry..

I support your independent research and taking the covers off the Turbo tuner, but this Shiv sniping makes you look like a school aged girl.

not sure what you mean... gear ratio is determined by speed and RPM, no matter how much horsepower you have, the ratio of speed to RPM does not change. for example... 2000rpms in 3rd gear will be ~35mph, while it will only be ~15 mph in 2nd... on a stock car, and on a procede car. gear dependent boost control could be easily done with some basic if..else.. statements pertaining to rpm and speed. The only time this is different is while revving in neutral, or spinning the tires, but who cares about boost control when free-revving?

Sounds like it would be too dependant on too many thing being stock or working correctly

welcome to the world of tuning with a piggyback... its all dependent on stock variables. but its also easily re-mapped for non-stock variables. Speed/Gear dependent boost would be no more difficult than any other PROcede feature.

What makes the v2.0 feel different over v1 is that there is no change in acceleration past the 4000rpm mark. Power keeps rising at the same rate all the way until past 5500rpm.

We could tune it so that peak power is reached at 7000rpm. But that peak power would be 325whp and we would have to severely detune the entire midrange in order to keep power below that

shiv

So to get a faster 1/4 would u still recommend short shifting at 6500, or would it be better to go all the way to 7000 with this new V2.0?

BTW- Great job dealing with terry, you've def won my support.

[DCJAX]

100rwhp over stock is damned impressive for such a "simple" tuning system. Hopefully by the time my car get's here I'll be able to pick up a final version, finely tuned, remote valet/wife switch etc.

One could only hope. Does the n54 use forged internals?

Shiv,

I also would like a window sticker for the front windshield. What do I need to do? I'm gonna call your vonage conglomerate today!

[Corey]

Was how much more boost it's running mentioned yet? I just skimmed through and didn't see it
