I am thinking of removing the automatic cutoff on the PSE between 30-45 mph. But it's not a job I feel comfortable doing by myself. Is there a shop in So. Cal that can do that or anybody done that willing to spend an afternoon with me.

Thanks,

Peter

 

Al you need is a couple of basic hand tools and about twenty minutes of your time. PM if you need info.

 

You can get info on how to do this on renntech.org

 

I remember reading on one of the boards that the info on renntech is not right for Cabs because it also disables the top mechanism. Anyone here done it on cabs can give me more info?

There is a black and grey valve approx 1.5" in diameter and 1" high with a vacumn line coming out of each end. Just reverse it and you are done. Idid it on my 99 cab. Takes 2 minutes.

 

this is exactly how i did it. it takes no tools and 2 minutes (the first time - 20 seconds every subsequent time). the valve looks kind of like a spinning top. there are two (one near the throttle body and one to the far right). i "think" (it's been almost 3 years) it's the one on the far right.

 

where is this valve??? coming out of each end of what???

Can you still turn the PSE off after you do this??

Thanks,

Peter

 

The valve is plastic and is located on the right side of the compartment. If you do this the PSE will be on all the time. To turn it off you would have to reverse the valve again. It has 1/2" nozzle coming out of the center top and bottom where the vacumn line is attached. Just reverse the vacumn lines. I let it this way for 3 years until I sold my car.

 

If you modify/disable the vacuum system, the dash switch (if you have one) will not function to turn the PSE to quiet. Not an issue in my mind, since I'd never turn it off...

Here's a pic--not mine--can't remember which site I got it from. The "check valve" is the item referred to above. On my last Carrera ('02) I tried reversing the check valve, but it didn't work, so instead I unplugged the orange plug labeled "from speedometer pickup" and wrapped the white and orange pieces with electrical tape to keep the ends from getting dirty in case I wanted to plug them back together (which I never did).

 

thank you guys very very much.

I'll try that tonight.

Peter

 

Forgive my ignorance, but what will this accomplish or change?

 

PSE has an annoying cutoff between 30 to 45 mph where the usually loud muffler sound is muted. this (hopefully) disables that.

I'd like to keep the on/off switch function which I can't find anyone w/ a cab who's done that. So this is the second choice. always on.

Peter

 

I just thought of something, I can't just unplug the speedometer pickup because my cab top also depends on that speedometer pickup. I believe that's why the renntech instruction effects the cabs in a different way.

But I'll try reversing the other thing, hopefully that'll work.

If anybody has done this on a cab before. PLEASE HELP.

Peter

 

You should be able to unplug the Orange/White assembly which is labelled speedo pickup as this is actually the vacuum solenoid whis is DRIVEN FROM the speedometer signal.

The vacuum soleniod only switches the vacuum lines to the PSE on and off and will not affect cab top operation at all.
