Hi there,

I'm looking for the operating instructions for the JCW DSC/DTC/eDLC system. All I could find on the DSC/DTC from the 2009 Coupe owners manual was:

One button push puts DSC into DTC.

Next button push puts DTC back into DSC.

A 3+ second push turns off both DTC and DSC.

Is this the same for the eDLC system? Is there a way to turn everything off?

I'm looking for this to finish the programming on the Auto Sportplus module that FES is finishing up.

Thanks for your help!

Matt

 

edlc is always on .

 

no , it´s not..

One button push puts DSC into DTC.

Next button push puts DTC back into DSC.

A 3+ second push turns off both DTC and DSC and puts EDLC on

 

This is more correct.

I think it's a bit more like this though (according to BMW)

Stage 1 (no pushes): DSC + DTC is on.
Stage 2 (one second push): DTC is on and the DSC is off
Stage 3 (3+ second push): DTC and DSC is off, and E-DLC is on.


stage 1 can go to stage 2 only (one second push)

stage 2 can go to stage 1 and stage 3 (one second push and 3+ second push respectively)

stage 3 can go to stage 1 only. (one second push)

 

Not sure if stage 1 is DSC + DTC, without going to my car and looking at the owners manual I can't say for sure. I always thought it was:

Stage 1 (no pushes): DSC is on
Stage 2 (one second push): DTC is on and the DSC is off
Stage 3 (3+ second push): DTC and DSC is off, and E-DLC is on.

Not that it really matters though, as DSC seems to intervene much sooner than DTC would (DSC seems like zero tire slip, while DTC allows a little before it jumps in). Same with EDLC, who knows if it's "on" all the time or not, as DSC and DTC would intervene before ELSD had a chance to do anything. This is all from what I notice when I drive, not anything technical.

Otherwise the above is correct, and you cannot turn off the ELSD

 

Now, who wants to test out one of my gizmos with the automatic DSC/DTC/eDLC stuff?

PM me if interested....

OK, so this is not about its activation and pressing of buttons. This is about the manner in which it operates, i.e. is it intrusive or not. I am not talking so much about everyday highway driving, but about tracking the car.

I understand that what it does is it briefly applies brake pressure to the wheel which spins excessively, effectively slowing it down and allowing the other wheel on the axle to catch up. This is of course quite different from what mechanical LSD on say R56 MCS does (the LSD which MINI/BMW decided to discontinue) I am not overly concerned about wearing out the brakes too much. I am more interested in your impression on how intrusive this system really is, especially if you owned/have driven a JCW stage 1 with mechanical LSD or R53 car and can make a comparison.

I am very worried that this may be too much of an electronic nanny type of thing that makes the car safer and tamer, and at the same time deprives the driver of some of the control/decision over what occurs for example when rapidly darting out of corners. Folks at Motoringfile claim it is better than the mechanical system, but they are rather vague about what this better means. My suspicion is fueled mostly by what I saw on D Motor (German car show), where Factory JCW Hatch was pitted against ABT tuned VW Scirocco. The driver (Tim Schrick) was very disappointed in MINI.

Check out exactly what I am talking about starting at about 1:55 and onward.... Please let me know you experiences/thoughts. Thanks

 

Beware: the translation in subs is pretty horrible...

 

but for example, Porsche is going to these types of electronic controls as are many, many performance cars and here's why: These types of systems can be predictive, instead of just reactive. The car knows about where the steering is pointing relative to direction of motion, throttle position and the like and can send the torque to where it can best be used before any wheel slippage occurs. Some companies call this torque vectoring. This can be combined with a reactive algorithm. So, the details are in the programming. But the bottom line is that the predictive nature of these types of systems have the potential to make a faster car through turns than reactive mechanical ones.

If we now turn the clock back to the first DSC systems on the Mini that were poorly programmed from an enthusiast point of view. the DTC and eDLC systems seem to be an effort to get the software biased a bit more enthusiast, I fear that the programming will still be a bit conservative for the performance driver.

You can't turn limited slip off, electric or mechanical.

 

I HATE my E-DLC.

If I don't launch with more than 2500rpm and full throttle, the brakes will lock me down and I don't move. Also, if I hit a bump with the throttle, it locks down as well.

I just drive around with DTC

 

Any updates on this issue?

 

i have a friend that is racing porsches and is very much into the electronics

i was talking to him about the mini DSC/DTC/eLSD programs

he called a friend at BMW racing and what he said was that there is no DSC or DTC or eLSD, there is only 1 stability program, just as in the porsches

DSC/DTC/eLSD are terms invented by the marketing department

what is happening when we go from [DSC] to [DTC] to [DSC and DTC off] is we are changing the threshold that the stability program operates at but that there is only one program operating and it can not be turned off completely

this has been my guess all along

let the flaming begin!

so is the consensus that the EDLC does hold back the car a bit - it doesn't seem to hurt it's performance when I watch it running DS in autox

 

Road and Track reported that edlc on the JCW caused the front brakes to fade in less than a lap. More than one JCW track day enthusiast has reported wearing out the front pads in a single day.

There are times in autocrossing when edlc annoys me no end by physically retarding forward progress coming out of a corner. Turning off DTC does not turn off edlc just as MINIUSA says.

Edlc is a poor man's limited slip. Porsche's torque vectoring system on the Boxster applies the brake on the inside wheel on turn in and electronically locks the mechanical lsd on corner exit. Since March 2010 new D stock MINIs have been uncompetitive in autocross due to the lack of a mechanical lsd.

 

Same here... My car did great locally and it was my first year.

 

i thought this started in 2009?
