shiv

from 0 to 100%, what will the procede default be set at?

90%? 80%?

and if we get 94 octane here, what type of gains do you see over 91 octane running the default you will have in place

Shiv

Is average boost used as a proxy for thermal loading? Or is thermal loading measured somehow?

I can imagine in a 20-30 minute hot lap session, one would have such high average boost that you can pretty much expect boost to tail off. This might be a good thing in 100+ degree weather but I can't imagine it'd be necessary in 45 degree weather.

nice work Shiv I asked for a linier torque map and you gave us the ability to make are own curves,with this one can tune his car to progressivly make more power as the rpms rise to make it feel more like a V8 or supercharged car.

Now a few ?'s

what if some one ran race gas,would setting to 100 in all cells take adv?
Say we throw on DP will there be any issues like some people have been having?Have you tuned V2 with Dps in mind.

Also if some one adds an intecooler and dp will the v2 compensate for the boost loss and add enough boost to make more power.

Tell us more about the over boost and is there a way to have the car make a few more psi at the users will?Say like someone is running a bigger intercooler and water/methy injection and wanted to run 17psi across the board.

For a drag strip tune you could lower the boost from 2000-3000rpms to help
launch. After 1st gear the engine never drips below 3500.

Not sure if this was asked yet, but what is the peak boost coming at now with V2? Right now with v1.45 Im getting 13.7-9 peak PSI. Id like to have a reference point with my gauge to know if Im getting all I should be and to fine tune it.

Peak boost seems to be 15psi:

It been real hot and we have been swamped with development work here lately. Peak boost has always been limited to 15psi, even with the overboost feature active

Shiv

For v1.47 ~14psi:

I thought there was another post Shiv made with some extra specifics for v2 but I can't find it, or maybe it was the one I posted above and wasn't really for v2.

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

+1 on that.

I would also be very excited to see a gear/speed dependant adjustability too, being able to adjust output lower for just 1st and 2nd gears only and be full tilt in 3rd-6th would be fantastic.
Shiv do you have any idea as to when you expect the gear/speed dependant adjustability to be available?

With the current rpm based percentage adjustability, we all seem to keep saying "torque adjustability" but won't it also directly affect hp as well? (ie: dropping a setting from 100% down to 80% would not only reduce the torque but hp would it not?

[ThomasMartin]

Its all good and well knowing all these cooooool features and i know SHIV just pops them up every now and again to get everyone excited all over again "PS brilliant marketing" but when the hell are we getting V2?

It doesnt help teasing us with all these cool features and you havnt told us up to what order number the V2 is shipping out to????

Now we love V2 even more but we going to have to wait 6 months

GRRRRRRR:mad:

[cn555ic]

great marketing skills but the delivery of the V2 is in fact very poor...The demand for this product i assume he knew was high...He should of planned ahead of time before releasing the V2...Made all his inventory enough to supply the demand...Customers dont want to hear that their orders are backordered or have to wait 3 to 4 months for something that they knew the demand was so high...I own my own business and sometimes dishing out more money to have a huge inventory is risky, but in this case the returns of the cash will be immediate as shown on Monday with all those orders...It seems it was just bad management....I am one of those unfortunate customer that probably have to wait in excess of two months maybe more, for something that if planned right should have recieved delivery within a week!!! Customers don't like to wait SHivs, but if they do as least give them some kind of information as to what the waiting times are!!! You are quick to chime in on things like people bashing your products, but questions about timeframe you ignore...Why??? We are you customer base and would like to know when our product will be delivered...JUst an answer will be enough!

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.

The user definable boost/torque curve allows the user to dictate the shape of their torque curve based upon their preference. 100% in all the cells represents a full tilt boogie tune (great for drag racing on race gas, for instance). While numbers in the 85-95% induce a safe and strong pump gas map for daily driving. This table will already be configured by us.

We'll be releasing more user adjustable parameters as time goes on, and as necessary for other upgrades (downpipes, intercoolers, etc,.)

Cheers,
Shiv

I have to hand it to you guys...you are taking the BMW TT to the next level.

Looking for the same with the 135i...then I will ditch my M3 and come to the dark side...

Shiv is saying it will probably be one of the next features, no confirmation on release dates though.

I believe the torque limiting was implemented for people with reliability concerns (drivetrain, etc), so I would have to agree that by limiting torque, you will also be limiting hp.

Product availability is not the issue, Shiv already stated that they are limiting the number of shipped v2 harnesses to mitigate support issues that may arise.

My opinion is that you aren't going to hit max boost between 2-3k and you are only gonna be there instantanesouly anyway, I say max that sucker out at 100% and work the throttle

A ton of great questions here and it all boils down to this:
How many sensors (input parameters) can be measured and how many are reasonable for END USERS to tweak given Vishnu has produced a plug-n-play product that seems to kick serious ass.

In this thread alone I've seen people asking for map/parameter edits for - Octane, Oil Temp, Gear, Boost level, exhaust mods, RPM
PLUS derived variables - boost over time, speed/rpm over time, etc

Having lived in the "full control of your engine - be careful what you ask for" world, its daunting to build an engine control system from the ground up EVEN with base maps ...
trust me, you don't want a full EMS interface - it gets UGLY FAST when you compound the variables.

From what I've seen so far, Shiv has been advancing this product in an extremely pragmatic USER-FRIENDLY way! Keep up the good work!

p.s. someone want to give me a ride in a proceeded 335 in NJ area while I await my car?

Shiv,

Still eagerly awaiting the answer to the following question by Cadence:

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...?

It would be extremely helpful to have this info.
Even if you don't exactly know, but if you know the range (ie: "somewhere in the 80-85% range would equal v1.47") would be helpful.

Thank you.
