Can the mph that raises the rear spoiler be changed?

For safety reasons raising the speed at which it goes up is risky. My thought is that instead the speed at which it drops back down be changed. Instead of 50 let's say 65 or maybe even 70. I always thought the 25 gap was a bit much.

That is probably a better idea. To change the speed at which it drops. Installing that button would probably be the easiest way to drop it back down.

I was really hoping a tool like the Durametric could change the spoiler operation speeds. I have not had enough time to explore what all the Durametric can do.

Fwiw, I picked up 1-2 mpg by going to an underdrive pulley.

That's already on my to do list, didn't know it helped mpg though, thanks.

I need to change out the metal impeller water pump I installed when in a pinch last summer. So I'm going to do the UDP and Low Temp Stat at the same time.

Hey don't mess with the 'active aero' man. That's right folks our cars were SO ahead of their time- so be proud of that sweet little, variable flap!
Kram- just think about what those huge GT2 air suckers are going to do to your aero...How about rigging up some slides that limit airflow through them above say, 50 MPH?

The bumper replacement is on hold. http://986forum.com/forums/general-discussions/55530-goy-my-new-front-rear-bumpers-wheels-way.html#post433870

You do make a valid point on that, but the cooling benefit would be worth it, plus it looks sweeeeeeet! The rear spoiler sticking up doesn't look sweet to me, but yes it's a nice and needed feature. I believe the slots in the upper portion of that front bumper would allow the air to escape and give front down force too. So that would probably reduce mpg too, not sure at what speed that would come into play though.

Like I said, this is a DD mostly, but I do take her out to some nasty fun twisties now and then. Hence the lager wheel and tire upgrade and ROW M030 suspension.

The rear spoiler isn't just about mpg, I think it looks tacky when up and I only want it up when needed. Seems the dash button control would be my best option.

Yaaa, I kinda like the function of the spoiler even if it is unattractive. It "spoils" both lift and drag in the rear which keeps the car planted at speed and also improves mileage. If it ain't broke, don't fix it. I can't even see mine while driving so it doesn't bother me at all.

You need some kind of an airfoil to get down-force. Again, it's aerodynamics/physics. I don't think air flowing through those vents will give you down-force.

Was that using your butt dyno?

You don't need a dyno to figure out mpg.

I couldn't find anything the aerodynamic of racing link showing that having the spoiler up would increase mpg. It did mention drafting would cause the car in front to have less drag.
