...i'm going to have to upgrade my brakes...

[retrodrive]

It is all marketing. Simple difference is that this is: "We have been in business for 26+ years..." vs you just got 100hp over stock. It would be interesting to see what the competition is going to do in order to catch up.

In order to get this power out of 2.0, I am sure the boost was raised from 1.45 which was high as is. My question is how long would the turbos last. I come from Supra world and I have seen my fair share of those TTs die with upped boost.

I have had Proceed for over a month and I am very happy that I went with the right company. Thanks for keeping it fresh, exciting and cutting edge for us Shiv.

What are the expected gains for:
- 91 Octane w/o exhaust
- 91 Octane w/ exhaust
- 93 Octane w/o exhaust

The majority will not have an exhaust so please let us know the approximate gains... Thanks

Yes, he may just be changing my mind on purchasing the exhaust.

We've been a bit quiet these last couple of weeks. Perhaps one could consider this to be the quiet before the storm.

First, let's take a few steps back:

We've always fancied ourselves as being innovators, not copy-cats. We've always approached tuning solutions our own way. At first, we're usually met with derision from "established" tuners. Tuners that proudly state that they've been tuning for XX years, have tons of technicians, lots of lifts and so forth. Well, in the end, it's the actions that speak the most loudly. Not talk.

When we first entered the BMW market with our Xede application that we developed, we were met with skepticism and hostility from just about all the established BMW tuners. They claimed that the ECU would "learn" around the Xede. They claimed that an interceptor approach to tuning wasn't a feasible solution. Some (cough cough.. Turner) have even spread rumors that we were blowing up motors during our development period. Since then, more than a few of them have approached us requesting private label deals, reselling, etc,. We turned all of them down.

Late last year, towards the end of our beta period, we discarded the Xede in favor of something more sophisticated and better suited for where we saw the N54 going as a tuning platform. We knew what we wanted to do and we knew we couldn't do it with the Xede for a number of reasons. So, to many peoples' surprise, we abandoned the Xede and developed our own proprietary computer (PROcede). Vastly different hardware. Different software. Different manufacturers. Not one thing is the same other than the off-the-shelf Deutch enclosure.

Once we abandoned the Xede that we used during the initial beta testing period (it never made its way into production), it was quickly adopted by many of the established tuners who initially expressed disapproval of it! Again, actions speak louder than words. After that, more talk ensued. Talk about how the Xede works just like the PROcede. Talk about how we abandoned the Xede for political reasons. Talk about how all the development we did wasn't really that hard and that they could have done it themselves if they wanted to or weren't so busy with other projects.

We just smiled and took the copy-catting as a compliment

And time moved on. While everyone was busy trying to convince customers that they were the real experts in this market and that they were offering something "just as good as" our PROcede, we were steadily developing new PROcede updates, improving both functionality and performance. Because in the end, actions speak louder than words. God, I love that phrase.

And that brings us to our most recent round of developments. Specifically version 2 of the PROcede software. It involves a simple 30 second software update for current PROcede users, using a laptop computer. It makes many functionality changes to the way the PROcede currently works. It has been tested quite thoroughly on our shop car (more on that later). Next, it will be tested on a few dozen customers who are ready and willing beta testers. At this time, we are working on the user software so ensure a smooth and seamless update. It will not be officially released with new PROcede orders for some time. Those who are already running a PROcede will be first to get behind the wheel of v2.

So what does it do?

We're not telling. Just yet, at least. But lets just say that a hunch of ours paid off and that we are taking advantage of some of the potential we engineered into the PROcede.

What we can say is that it vastly improves power output. It also has a postive and noticeable effect on partial throttle driveability and power delivery. It also has a couple of features designed specifically for heat management which is especially useful for those who run their cars at the track and/or don't have the optional Sport Package oil cooler. Also has provisions for managing drivetrain stresses. Again, really nifty stuff. A few of these ideas materialized from the work we are doing on the new Mini Cooper (direct injection turbocharged valvetronic BMW motor) and the Porsche 996tt/997tt (just baddass awd with variable turbo nozzle geometry). I think that goes to show that specializing on 1 kind of car, for a very long time, rarely improves the breed. Sometimes you need to try new approaches, on vastly different platforms, and think along different lines to get the best results.

And the results on 93oct with our exhaust system:
(same day, same dyno, within a 15 minute period)

Stock (just exhaust, no PROcede) 289whp 299lbft
with PROcede v1.45 332whp 380lbft
with PROcede v2.0beta 376whp 406lbft

v2.0beta gains over stock ECU: 87whp 107lbft
v2.0beta gains over v1.45: 42whp 26lbft

v2.0beta gains over a totally stock car (estimated): 100whp 126lbft

So how does it drive?

Geezus. Whereas the standard PROcede map would pull hard up to 5500-5800 and then soften up a bit, v2.0beta just rips towards redline. Power never seems to fall off. Drives just like a proper M-motor in the way that it loves revs. But unlike an M-motor, it makes simply staggering levels of low end and midrange torque. Truly an incredible powerplant. I just went out for another drive while I was writing this post to remind myself what it feels like

So what is next?

There is still quite a bit of mapping to do before the calibration is to be considered complete. Today was more like a maiden voyage on the dyno than anything else. What we'll probably end up doing is dialing torque back to the 380-390lbft range while still keeping power in the 370-380whp range. This should make for a real nice, natural feeling engine that doesn't induce excessive drivetrain stress. We haven't even come close to fully enhancing the 2000-3000rpm torque output yet. We will see that part of the curve fill out nicely. We'll probably get another 2000-3000 miles of hard testing on our car before updating beta customers.

But so far, we're really happy with the initial results. As far as hp gains go, it's like putting another PROcede on top of a car that already has a PROcede Still have some more work to do. But hopefully this update brings to light what we do. And more importantly, what we don't do.

Things are looking very bright for all you current and future PROcede users

We'd like to thank ALL of you for your ongoing support. If it wasn't for all the positive feedback and business, we would never have been able to invest this much development time into our product. Thanks for sticking by us through all the silly flame wars, posturing and e-shananegans. Hats off to you guys more than anyone else.

Best Regards,
All the nerds at Vishnu Performance Systems

This is why i have the PROcede!! Thanks Shiv and Vishnu Keep up the great work!

[musc]

Great work, Shiv

[DLSJ5]

Very impressive.

[bnj]

Shiv, I would consider myself being a pretty demanding customer expecting the words to turn into actions sooner rather than later. I have been a bit disappointed with the delays in Stage 1 & octane specific maps and custom tuning interface. But now... things have changed. The power will not only meet, but it will Xede - sorry i meant exceed the advertised one. Actions speak louder than words. I'm happy you have been concentrated on the actions. Actions that now have been surprised me very positively. Congratulations. Now it is totally acceptable that there is no V1 stage 1 map since there will be V2 stage 1 map.

Hope you are able to grow your business, acquire more resources and implement the necessary actions to launch 2.0 soon. Since actions speak even louder than dyno graphs in the forum Great work! Thanks for that.

PS. I need to call you soon in an urgent matter

[bronco]

Can someone else see the Corvette territory??? Good job Shiv and team

[Pele96]

Great job Shiv!

[ZBMW]

Shiv, I'm really impressed with the numbers and graphs. What concerns me is that the stock torque curve, while looking pretty anemic against the Vishnu upgrade, comes on faster and maintains itself well on up to 5000 rpm or so. This is what BMW wanted, in order to give it it tractability and, probably to put less strain on the engine components. Or so I understood from the article in Eurotuner.
You did mention that you had more work to do in this area, i.e. smoothing the curve more in the lower rpm range. The torque curve would be perfect if you could get it up near peak faster and at lower rpm's and hold it there through 5000.
Is this feasible or is it one of those parameters that requires compromises?

- 91 Octane w/o exhaust
- 91 Octane w/ exhaust

Very important to me.

I noticed the correction being = to 5 instead of 1 (as mentioned by someone else in a recent post)

If I had to make an educated guess at this point though I really wouldn't worry too much about it since there are a good # of procede/AA cars running around without any tranny/clutch/differential problems. It also depends how you drive your car. If you maintain your car well and drive it hard every once and a while that is much different then if you beat the piss out of it every time you hop in the driver's seat.

[WAYNEBO]

All hail Shiv... our grass-roots, Vishnu God of the 335i!!!!!

I have only one question to Shiv... when are you gonna start selling PROcede to Hamman, Hartge, Dinan, and even BMW stealerships? Imitation is the finest form of flattery!

[Terry335]

Interesting VANOS reading:

http://www.bmwworld.com/technology/vanos.htm

From what I gather the 335 is a double-VANOS system, meaning exhaust and intake cams can be controlled separately. It seems to work off oil pressure solenoids so it's probably an analog signal, but if it is digital, it's going to be hard for Xede to catch up. I gather the concept is to hold the intake valve open longer to allow the cylinder more time to fill, but I don't have any experience with this kind of variable cam control.

Looking forward to more information such as boost curve like everyone else.

That 5 indicates the level of graph smoothening. Not correction. The correction method we used (and have always used) is STD (see top right of graph). Due to atmos conditions, it was a 1.02 (or 2% over uncorrected). Nothing funny going on here.

There is always gotta be a Hater in the bunch. Terry, your negative presense on this thread is proof enough that you are too drawn to Shiv's front-running. If you don't like it, then why are you posting here? Go make your own and go away. Meanwhile we will all enjoy the dedication, experience, and most importantly R&D Vishnu puts behind a product continually pushing the envelope.

[gonzo]

Uh.....I almost sold mine. Company car and all. Uh.....how much do those beggers make a day? I think I am now going to think some more about thinking this over. Excuse me, I have to go buy my boss a bottle of something.....................Damn you Vishnu!

Thanks Shiv

As for concerns about boost, there aren't any. We're not going to explain everything right now because that will just lead to more Terry-induced confusion. But, rest assured, we will never tune anything to an unsafe level. Regardless of whether the car belongs to a manufacturer, a customer or us.

Also, keep in mind that the v2.0 calibration is not close to being done. This was just a first shot at the dyno. We still haven't touched the sub 2500rpm range. Expect this area to be boosted substantially. Ultimately, we may limit max torque to 375lbft of so. Unless some people want the full whallup of course. Power, however, will not be limited as this has little direct bearing on drivetrain stress.

cheers,
shiv

[bnj]

V2 will be safe - why not, since AFR is ok. Especially if the torque is kept a bit lower as Shiv has planned. High torque would be an unnecessary stress to drivetrain.

[retrodrive]

I am not concearned about the engine or tranny not holding up. I am more concearned with stock turbos dying too soon on me.

Well, it is too early to speculate about that unless more info is supplied. This is not the time to talk about it. So far I am very happy about all this new found power.
