Do 89s have the speed compensated steering?

Sorry its a dumb question and i tried searching but found nothing. I remember long ago hearing that it wasnt an option until 90 but i wanted to ask to make sure. Thanks everyone

VAPS, and no.

VAPS (Variable Assisted Power Steering), wasn't around untill '93.

Thanks guys, i thought thats what it was but i couldnt remember for sure. I can say i miss the steering in the bean though. Oh well, hopefully i will be happy once i rip that soggy stock garbage off the suspension on this thing.

Ive got a 101 fever right now so i couldnt remember what that it was called vaps Lame excuse i know but i promise thats what it was

With a fresh, tight suspension, the non-vaps SHO is a blast to drive. Tons of feedback, and so predictable.

Ive driven one SHO with vaps.... freaked me out

Stupid question... What the **** is VAPS? I have heard of it but i never knew what it is.

As mentioned a couple of posts above, Variable-Assist Power Steering. The steering assist ratio changes dependent upon your speed.

Personally, I have no issues with either, except for when you own both Gen 1 & Gen 2 SHOs concurrently - then it's a trip to bounce between the cars.

I prefer the non-VAPS now, as my other car doesn't even have power steering.

Variable Assist Power Steering. Basically the steering is overboosted at low speeds making the steering easier to turn while parking.

then how come the 89 has a pressure switch on the rack....mine has one...if im not mistaken it measures the prssure of the fluid in the p/s system...if the switch is faulty it will throw a soft code..

The ECU uses it to evaluate the load the PS pump has on the motor so it is able to compensate the idle speed as to not put too much load on the motor.

Its just a simple on/off pressure switch. It signals EEC to raise the engine idle speed if the power steering system pressure exceeds Xpsi, (can't recall the pressure trip point) which could stall the engine due to the load from the PS pump.

What speed does the VAPS come on at?

If the engine is running the VAPS is on.

Here is an article concerning it:

Acually, i should of said when does it boost the least (making the steering harder to turn). According to that link, its 60 mph. That works for me.

GenI SHOs did not have VAPS, though it was available on the 3.8L.

Just a bit of info I discovered when trying to find a rack for my Plus.

I got my reinforced motor mount and alsfb's in today and woah what a difference! I like the non vaps now! You were right. I cant wait to see how it is with the tokicos and intrax!
