TEMS firm tied to Auto trans shift points

[Amontgomery]

I was watching Top Gear videos on Youtube. When the Enzo(F60) one came up I noticed that the transmission shifts were accompanied by stiffening of the rear suspension to prevent dipping under load, keeping the car stable under hard acceleration.

So I am thinking TEMS cars have suspension that stiffens under hard braking, turning and acceleration, Would it be possible to set the controller up to where it would send only the rear shocks to firm at the shift points of the automatic transmission?

you are correct.
for the rear, you could disconnect the front actuators or get tems adjustable struts from tokico for the rear and not for the front.

But would it be possible to add shifting to the things that make them go from sport to firm? Or do the Firm mod for just the back shocks and have upshifts be the trigger.

Your question was already answered. Aftermarket. But I am missing your question on the shift points. Shifting to sport, or having all lights on has no bearing on shift points. TPS does, and at WOT, all three lights will light up.

 

[Amontgomery]

Is it only at WOT? Or are there points before that it stiffens up?

We have a ECT too......................................

Braking, vehicle speed, steering angle, and throttle position determine which setting the shock is on.

 

[Amontgomery]

And it applies changes to all four shocks at the same time, provided the hardware is in operational condition? It doesn't meter to fore/aft based on acceleration(needing more to the rear), or braking(needing more to the front).

What I am talking about is a way to still keep the entire system operating as stock while adding the function of metering firmness to front or rear varying on needs. And at shift points under anything more than half throttle would be a need to have only the rear suspension to go to firm, just as braking would be a need to meter firmness primarily to the front suspension.

You know, your whole suspsension and IRS was designed as a unit. Keep that in mind.

Not a good idea monkeying with front and rear dampening rates separately while on the role. I think the engineers that designed tems would pass-out if they thought anyone would try this.

The mechanical system is far too slow to react to try and make it "active"

By the time it's reacted the "event" has passed.

It wasn't meant for events you describe. Mr slice and dice. :biglaugh:

Sweet idea, but have to agree with most all of the other replies. The main concern would be as Ian said the speed at which it could make the adjustments. Liken it to trying to get a Commodore 64 to run Vista ^^

If you want a canyon carver, start with a non TEMS car. It is just some extra weight anyway.

http://www.youtube.com/watch?v=aOwP02sNzyI is what he's talking about. That's Nick Mason's Enzo, if you're wondering why he keeps quoting Pink Floyd songs.

I bet it would be possible with some custom logic, since I can't imagine the TEMS reaction speed and the auto tranny shift speeds are all that different from each other. Somehow I don't think it would be all that impressive, though.

I've never been in an auto Supra. Do they have traction problems during shifts?

 

[Amontgomery]

I definitely agree about the hardware not being able to keep up with the idea. If the TEMS couldn't do it what about an aftermarket equivalent? Say Tein EDC or equivalent.

I don't know if auto cars will have traction problems in shifts as I don't have enough power in mine, however I can see how it would as an auto stays in boost under hard acceleration when the car shifts. But this isn't the reason I was thinking about this. The reason I was thinking about it is for higher speed stability during a shift with a high powered vehicle. I am sure you have seen the rear end of an auto car dip when it engages the next gear under hard acceleration. When the back end goes down the angle of the front end comes up letting air under the nose. Not a good thing.
