^^^Somehow, Ruf found a way to do it, so it must be do-able. Can't imagine that it's a huge deal for someone who knows how the module works.

Allow me to rephrase...I wish there was a cheap, easy DIY way

Jon93

If you press the spoiler down button BEFORE you reach 80km/h, does it prevent it raising for the remainder of the journey?

Edgy01

Does the 993 spoiler deploy when the engine bay temp reaches a certain figure? I know that the 997 spoilers are also affected by that. (The 997 spoilers go up at 75 mph (actual--not necessarily indicated) and then go down around 51 mph.

Im pretty sure an erect spoiler does produce enhanced cooling. Every aspect of the 993 design has a purpose.

As per the speed on the P system tester, open trigger on mine is at 84 km/h and close is at 12 km/h, with half worn wheels. It is not heat related.

I think we need to get a vote on how effective it is on cooling.

Personally, I doubt there can be that much difference. Especially that the engine bay is not really exposed anyway, nor should it be.

Anyone else not a fan of how the 993 looks with spoiler up?

jimbo3

That's what I was thinking, too. Seems that the value of some component in the circuitry simply needs to be changed proportionately. I'd take a swing at it, but I'm completely clueless when it comes to electronics.

It may well be just a case of changing a resistor in the control unit like with the VW corrado electric spoiler.

anyone good with electrics?

if you look at the spoiler when it is up there's a plastic acordian barrier that gets pulled up.. so that's what shoves air into the engine... not sure how effective it is at cooling (i trust the porsche engineers), but also creats some downforce AND gets rid of the light on the dash

Think it goes up at 50mph and this DIY to dissable the light says so too - http://p-car.com/diy/tail/tailwarninglights.htm

Not a fan either. I'm going to try the disconnect DIY and maybe go back to stock during the really hot summer months.

Wouldn't finding the fuse for the spoiler, and taking it out solve this issue?

Falcondrivr

pulling the fuse will result in a warning light as the car will see it as a spoiler failure. Disconnecting the control unit will stop the activation, and diable the warning circuit. Plus, it's easier than pulling a fuse. Really.
This is what you are looking for under the pax side dash, with the plug pulled.

So what I suggested (post #9) doesn't work on a 993? Just curious...it is such an easy way to control the spoiler.
Pull two pins, cover with electical tape and you are good to go. Spoiler moves only via the ****, and raises by default at 76 MPH (and must be manually lowered).

I'm interested in seeing if it works for you guys? It's worked great for me these past couple of years.

I'm right there will all of you, I prefer the spoiler down. I installed a RUF spoiler module after following a 993 in stop and go traffic. I was struck with how stupid it was to see the spoiler keep going up and down. I talked to a number of "experts" before I bought the module and the concensus was that the spoiler really doesn't do anything until 80+ mph. At that speed the shape of the car starts to create a low pressure area over the rear deck which can limit air to the engine and at even higher speeds will produce lift. The rear wing corrects that but at sub 100 mph speeds it's really more about cooling than stability. I have NEVER had a cooling issue with the RUF module and they assured me deployment at 70 was well before it was really needed. As long as you're not driving 80+ for sustained periods in hot weather I think it's pretty safe to unplug the spoiler but if you cruise the autobahn you probably still want it to work.
