iX Random Thoughts/ Questions

[Chrisbike]

Why the heck does the iX have two clutch switches?

[TimeMachinE30]

Can we just ask questions or does an answer actually need provided?

I think one is for the ECU and one for cruise control? I only have one, but i dont have cruise control..

Mine has a switch but it will still start without the clutch pressed in

Just ask questions if you have one; I didn't want to make a useless thread but was curious if anyone knew this.

That might make sense. Maybe it's some sort of signal sent to the ecu and it effects the "traction abs system"

No e30 has the clutch start interlock keeping you from starting it until you depress the clutch; it wasn't introduced until the e36.

upgrading the rear sway bar to 16mm? I found a eibach rear bar on another e30 at the yard. And I figured it wouldn't hurt it. But I also don't want the car to feel too neutral.

One is for the abs, the other is for cruise control.

Easily deciphered by looking at the ETM. ;)

Yeah the one on the bottom is cruise control, top is abs

What does depressing the clutch while the ABS is active do?

it's for engine braking control.

if you lift the throttle without putting in the clutch on an icy surface and the wheels slip, the mercury switch on the driver's side will stay open (open = you're not slowing down) and it will open the ICV (by sending an on/off signal to the DME on C101 pin 19), which should reduce engine braking and stop you from slipping.

Basically, it's a really crude, early version of ASC/DSC.

I am 100% sure that I can start my '91 IX without depressing the clutch...

Sending unit

Will an e36 fuel gage sending unit fit my e30 325i??

[nando]

no.

Wow, learn something new everyday. So in dry conditions, driving along in 4th gear I let off the throttle and the car slows down.

If icy conditions, I let off the throttle and something different happens?

I never noticed it in all my time in the mountains, but then again I've never had trouble in the iX in snow/ice. ;)

It detects if the wheels locks up during engine braking, and if they do the ECU raise the engine rpm to let the wheels get rolling again :)
Its like a ABS system for engine braking!
