Can CASIS light be disabled?

[dgcate]

My driving habits dictates that that cheesy little "shift for better fuel economy" light/arrow in the tach is always lit. Has anyone found any easy way of disableling it? It's just a minor annoyance at night, but if I could turn it off I would.

Thanks!!

David,

Here's one way to do it:
On the six spade connector on the bottom, center of the back of the tach, the CASIS/upshift light is controlled by the black wire/spade that connects to the upper left corner (Terminal 1) of the connector. Disconnect, tape off and you're done.

Good luck,
Tim

Sounds good to me. Thanks Tim...

It is annoying in it's "shift now for best fuel economy" mode, but Porsche being Porsche
also programed it to work as a " shift now you've hit redline" light under flat out acceleration.

The secret is to drive flat out all the time, and it will never come on except to tell you " shift
now stupid you're about to grenade the engine".

Jim Garfield has it right...it works both ways....keep your foot in it !

I disabled it on mine. It only comes on as a "redline" warning now. That little red light stays on a lot when I'm on the track. (Motor is suitably modified to allow this, don't try this at home, not recommend if you are nursing, etc.)

Ice pick to the light works....fixed my door and seatbelt buzzer....the City frowns on shotguns.

How did you do that?

Hmmmm I guess I am a purist...I like the CAIS light. Very useful when shifting at full disco...who better to tell me the optimal shift points of the engine....than the engine?

Can't just ignore it? I also still have my buzzer installed but I only have 31k on the car and it is an 84.

F1 drivers use a whole bank of 'em, so it can't be all bad.

It's useful at the track. The rest of the time it's a minor annoyance. My old Escort had the same "feature"...when I got the car when I was 19, I figured the light would burn out eventually since it came on all the time.

I think I replaced every single bulb on that car with the exception of that one. It was still working the day the cops towed it away. :\

Optimal for fuel economy, not performance. And if fuel economy is your goal, then you have the wrong car, I'm afraid.

That's just how it works. I didn't do anything special when I disconnected the black wire.

This has been on my punch list for some time - but the way I was going to do this was at the DME box under the seat. Wow - five minutes, one small piece of shrink tubing and that *(^% light is off! I tried to get it to go on at redline, but I keep chickening out at 6250...

This board rocks. Thanks!

You could also just ignore it. After a while I didn't even notice it anymore.

Yes, I ignored it pretty well, but I also found my eyes momentarily distracted by a light on the panel just as I'm winding up through 3 grand. I think that's bad. I have enough problems with the whole shifting, steering, thinking, chewing gum thing that lights going off for no reason must be stopped.

The few times I drive at night it's really annoying. And in five minutes, I could reverse it.

For me, this is an immediate (and reversable) improvement in my cockpit environment. Now if I could just do something about the monkey behind the wheel...
