Two units: XEDE and PROcede - both:
Intercept the CAS (Crank Angle Signal) used by the primary (BMW) ECU to determine when engine events occur relative to the "Bang" of combustion that makes the torque and power of petrol combustion. The signal is modified in order to make ignition timing adjustments that are needed to safely accommodate increased cylinder filling (with air) from higher boost pressure.

and Intercept the load measuring analogue signals TMAP etc. to increase the boost pressure (in a similar way to the part the "Turbo Tuner" does);

and drive directly or intercept and modify the PWM (Pulse Wide Modulated) signals supplied to the wastegate control solenoid valves (More important ways to provide a stable increase in boost pressure);

and bias the wide band AFR signals in order to achieve changes to the prescribed AFR (fuel mixture) to sustain stable temperature control on the engine and turbo components exposed to high temperatures with the increased power and torque;

Optionally (for both XEDE and PROcede), a frequency signal like a VSS (vehicle speed sensor) signal can be intercepted to provide a limited output at say 128mph for a car with a 130mph speed limit in order to prevent speed cutout.

And, theoretically, AFAIK from the PROcede, you could drive the Dual VANOS solenoids or intercept the CAM sensors in order to achieve changes in the Cam timing. (I still have never seen any tangible improvement at all, by changing the VANOS on a 335 engine)

Regarding Digital Input/Outputs

1) VANOS control. Lachlan says he has not seen any gains. I have. You take your pick and ask when has VVT not been helpful in tuning a turbo car. You'll need at least 1 pair on digital inputs/outputs to phase change the CAS.

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.

They both do all of that exactly the same. The next bit is more difficult to quantify as I can argue that Vishnu is slowly getting the programmers at Haltech to get the PROcede software to do all the things that the XEDE software already has with conditional and delta-time controls over timing etc. and Shiv at Vishnu can argue that he did it first with the XEDE and that AA and ChipTorque are using his early development to get the software to produce his old results. Sour grapes or BS - unsubstantiated claims - blah blah blah.

I'm not sure why you suggest that we are duplicating the Xede software. Especially the conditional and time-based features that we conceived a long time ago and worked with you in implementing. I think we've all moved on since then. Maybe you'll change your mind soon. Duplication has never been our thing and you should be well aware of that, more than anyone else.

That said, we wish you guys the best of luck in your future endevours. I hope your new partners keep the development wheels turning at the same speed we both enjoyed during the last 5 years.

Regards,
shiv

Keep it up guys, as much is its going back n forth....it is great info for people who dont know about the units and how they opperate.

good info!

[Sparky66]

Shiv,
Will you be having an Australian Distributor who could market the Procede downunder ? Obviously not ChipTorque but what about Haltech. I noticed that they market a "Interceptor" unit which seems identical to the casing shared by both ProCede and Xede. Not to sure who is using whose system ?? I do know however that it has 4 inputs/4 outputs.
Go here for a look at Haltech :http://www.haltech.com.au/interceptor.htm and here for specs: http://www.haltech.com.au/downloads/InterceptorSpec.pdf
It would be good if we could get local support and tuning for the ProCede as it seems to be potentially superior at this stage to all the others out there.
With the potential of major upgrades, I can't see myself using anything else at this stage.

If Shiv hires me, I'll happily fly to Aussie for marketing and installating. I am a tuning whore.

Yes indeed and thanks for the support. We will be setting up 2 distributors in Australia. One in Sidney and one in Brisbane. But not for another 2-4 weeks until we are able to supply them with our production harnesses (currently being made in quantity by hands other than ourselves... finally!). Both shops have in-house dynos and both are very experienced. The Interceptor, PROcede and Xede all use the same off-the-shelf Deutch enclosure. It's really the only readily available enclosure that is small, has enough i/o pins and is water tight. That's why it is so popular. Beyond the enclosure, the Interceptor and PROcede have common origins but differ substantially in terms of functionality and application support. If you check back with us in a couple of weeks, we can refer you to our Aussie dealers.

Cheers,
shiv

PS. Drewko-- wouldn't we be looking for tuning pimps?

Hey finally some decent technical information from Shiv!


Help us make a little sense out of this. Here is what Lok posted in another thread:

So, does the 335 implementation require an analog channel for map, 2 analog channels for o2 sensors/fuel, and a "crank/vanos" channel for CPS?

If so, does that leave an additional digital channel, 2 high current outputs, and a frequency input?

[Sparky66]

Thanks Shiv,
this is very good news for all of us in Oz. Will spread the good news in E90post -Aussie forum.
Thanks again for your support. By the way, is one of these the same tuning shop who prepared the 335 coupes for the WPS 12hr Bathurst Easter Race ??

Drewko,
your welcome anytime to share your services with a fellow tuning whore.
Performance upgrades progress at a slower pace here but we are prepared to catch up.

What i have written in my post is purely my opinion. Take with a grain of salt if you will.

[Jean@ActiveAutowerke]

I am getting confused. I have a question for you Shiv to clear up some of the info on the board.

Are you using a Haltech Interceptor?

I'm confused as well.

Why does that matter?

Seriously... why dont you purchase both and see if they are the same

Vishnu,

Please let me know if you have any plans for Singapore. I have 30 over ppl keen on the procede. I really wish for you to work out something for us. We have a BMW workshop here capable of doing such things. All i need is instructions.

Cheers/END OT.

Just answer the guys question and stop giving the run around.

Easy, big fella. No use getting worked up over something that doesn't affect your life.

[Ryan(e92)]

Yea shiv tell him who makes procede so he can steal it and then talk about how his big company is better.

So, it’s a Haltech Interceptor with special firmware?

I would like to see Shiv answer the question directly. This is interesting.

[OpenFlash]

lol... I did answer it. Please see post #173. If we can reach 6 degrees of separation, I'll be impressed.
