As previously mentioned - the only time when you REALLY NEED  the EDL to 
kick in is when you are trying to accelerate out of some crappy surfaces - 
in this case you can just switch the ABS back on :)  It's a "nice to have" 
putting the power down exiting a tight corner, but not that big of a deal 
(no different than a pre EDL car at speed where the locker isn't going to lock)

If you've installed a torsen rear, then you're really not missing much by 
shutting off EDL - again unless you're stuck in the mud/snow/gook/stuff and 
trying to get moving...

To me the real problem with shutting off the ABS in a EDL (4 channel) car 
is that you're disabling the rear proportioning, which will lead to a 
tail-happy rear end.. that's the biggest problem. (Especially if you've got 
BR's in the back!)

If you really wanted to go there, someone would have to spend enough time 
to figure out how to "fault" the system so the ABS goes off, while the 
"Proportioning" (sometimes called Electronic Brake Distribution "EBD" or 
Dynamic Rear Proportioning "DRP") stays on.

Whether that disables EDL too really isn't something to worry about at that 
point.

Just IMHO of course :)


Cheers,
Keith
