Will it be delimited with the 2.0?

[enrita]

No. You need a separate box bms is developping now.

[Mike@N54Tuning.com]

It won't be part of JB3 2.0. From BMS' FAQ:

"Why doesn't the JB3 include a 155mph speed limiter removal?

While "clamping" the hardwired speed signal to the ECU as other piggybacks do will allow the vehicle to exceed 155mph, the true vehicle speed is recorded by the stability control module and other modules using sensors at each of the four wheels. These modules will always contain the true vehicle speed regardless of the ECU clamp, and in the event of a warranty claim may reveal the car has been modified. For those customers who are out of warranty and fully aware of the extreme risks and danger in operating their vehicle in excess of 155mph on race tracks, BMS offers a stand alone speed delimiter. Email us for details."

Everything Mike said is true,and was backed up by my service tech. If you do this mod with the Procede or the stand alone that BMS and all of the vendors like Mike and I offer then you have to be aware of the warranty issue. My tech said they are not dumb and when their is a big warranty claim it is one of the first things they check for sinc ethey know it can not be hidden or erased. It is a use at your own risk mod, and I guess Terry just never wanted to make it too easy for people to bypass and get into trouble without thinking twice about it. I personally think that was a good decision on his part. He is trying to save you from yourself.lol I know I would lack the self control to not turn it off

As Mike said you can email him or any BMS vendor about the stand alone delimiter.

With the chip burner that was needed prior to 2.0 and the BT tool (clear codes) and also the stand alone speed delimiter and BMS V3 o2 sims, its almost the same price as a Procede, but not like Procede which comes in one neat little silver box!!

BTW.....Great job though Mike, as I have heard nothing but good things from JB users using the JB3 2.0..

So BT doesn't clear speed delimit? it still leaves traces?

No the Bt can not do anything about the traces left by it. There is no way around it. As Mike mentioned the four sensors in each tire and the stability control modual still will show a different value than the ECU value which has a clamped value. That is how they know at the dealer. No way to clear that.

Right.

[FotiosF90M5]

what if the car gets a new software update? would that clear it. I buried the needle a while back and the car has been updated after that when they replaced a turbo. I have a dealer that "looks the other way" but now Im worried.

It is stored in the stability control module so an ECU update won't overwrite it. The good news is the dealer may never check unless they do a PUMA case. Just hope you luck out!

Mike, how did you determine that the Stability control module even stores unlimited historical max/min data? Because I have info that suggests otherwise.

...so am I in trouble? It had to have been close to 170. damn that procede....

170mph is certainly potential trouble in many ways (public safety and potential jail time being just two). But not in terms of mythical "stored" data in the traction control module. That's pure FUD spread by those who can't offer a native speed delimiter option because a) They don't have a 12v power source in their PnP harness and b) lacking the processing power to accurately replicate a high speed square wave (yes, just like the crank angle sensor wave).

The on board electronics store historical data that could be useful in case of an accident. Vehicle speed being one. But this is only the last several seconds of drive time. Just enough to see what happened prior to the accident. Not what happened four days ago when you took your car to the race track and pinned the speedometer down the front straight.

cool. thanks for the explanation.

[wonsungnabi]

you people are crazy! why would u ever want to go over 155mph?

I have no idea . happens pretty quickly though. brain synapses possibly.

[Digital.James]

how about for the guys who dont have 155mph, why not raise their speed limits to 155...

[Mike@N54Tuning.com]

The data is passed via the from stability control module via the CANbus to all the other modules including the ECU. VMAX is stored in more than one location just like maximum RPM. The airbag black box being only one of them. Just ask your dealer. If anyone wants to believe otherwise then whatever helps you sleep at night. This is just the information I received, so if anybody is doubtful please check for yourselves.

On the SLD box, it uses a PIC12F processor and a 12v fuse tap. It's a pretty light weight processor compared to the JB3. It's very similar to the Active SLD which has been on the market for some time. As long as you know the risks its easy to add on.

Question regarding the stored value. So, if a car was driven over 155 mph and encountered a major problem as a result of it. Would the data still be stored to prove it was over 155, assuming it went in to service right after?

And the VMAX comes from the speed signal that goes into the DME. Which is clamped to 130mph

You'll also notice that the vehicle speed data floating around in the CAN network is also clamped. See for yourself. You have a BT tool and a PROcede for testing I'm guessing. Rev.1 would be fine.

If you are using a PROcede to get around your speed limiter, the logged vmax will be approx 130mph since that is the point at which we limit the value.

There is always some degree of risk when going beyond the vmax limit. Usually cars are limited for a reason (non Z rated tires, aerodynamic instability, inadequate brakes, etc). Which is why we made the speed limiter defeat a user adjustable. It only works if you turn it ON. Default value is OFF.

FWIW, I leave it OFF. If I pick up another 30mph in trap speed, I might have to turn it ON

And Mike, when a processors only job is to clamp a square wave signal, you don't need anything heavyweight. But when you are (or aren't) simultaneously controlling timing, running multiple PID logic for boost control, adjusting fuel, reading rpm, dc%, tps, iat, datalogging, and everything else the tune is doing, things get a little more taxing. And as with the crank angle sensor, the DME isn't tolerant of missing teeth/errors in reproduction.
