Default removing asr?

hey guys, im looking to remove the asr one my 94 6 speed. i want to remove it to open space up under the hood and dont need it. iv looked into it a bit but couldnt get all my info. obviously i need a new throttle cable, i saw that i can use one from a 94 f-body without asr. i can remove the lights from the dash. my question is, is this gonna mess with my abs, and is it going to retard my timing? anybody have any experience with this? thanks!

All that is required is to turn it off permanently and switch out the throttle cable.

The devil is in the details.

what exactly do you mean by turning it off permanantly? will removing it affect my abs or engine?

The following 3 photo's were taken a few hours ago. Just finished removeing the ASR box on my '92 but the car's not up and running yet.

You'll be needing the throttle cable from a 4th gen LT1 Camaro/Firebird which did NOT come with trackion control. Traction control was "standard" on our C4's, but was "optional" on the Fbody's.

The part number for a "non TCS" Fbody cable is GM-12550676.

They've been discontinued, but there are plenty of used ones still out there for a reasonable price.

I picked mine up for about $45 from Hawks Third gen.

http://www.hawksthirdgenparts.com/94...ttcsnewgm.aspx


First disconnect the cable from the throttle linkage, then make your way inside the car and remove the gas pedal assembly by removing the two small bolt that secure it to the firewall.

With the pedal assembly removed, you'll be able to access the small, round plastic clip that holds the throttle cable onto the pedal assembly itself. You'll never be able to access this plastic retainer clip on the back of the pedal if the pedal is still attached to the firewall on the car (ask me how I know) -


From what I gather, the traction control system will still work, in terms of timing retard, should any wheel spin be detected, you just won't have the gas pedal kicking back up on you anymore now that the ASR box has been removed. ABS apparently, still works as well. Again, this is from what I've read.

You'll have to disconnect the ASR fuse and "possibly" have to remove the bulb behind the DIC if you get the ASR light come on. Seems to be hit or miss as to whether the warning light comes on or not...

Because it's so hot outside right now, I haven't attached the new cable to the gas pedal just yet, only to the throttle body itself, but as you can see from the pictures, ditching the ASR box sure does clean up the engine bay considerably.

I've read of at least one person having to trim the "throttle stop" on the back of the gas pedal in order to get the throttle blades to open up 100% but that was just one person. At least, it was just one person who actually reported having to do so anyway. Maybe everyone has had to do the same and just left that part out of the details.

I'll know for myself as soon as I attach the cable...

Again, the part no. is 12550676 for a non-TCS 4th gen fbody throttle cable.

Hope that helps.

man, you are always a huge help. i used your opti walkthrough about a year ago and i have been following your suspension threads because i did my suspension this year. so it should just be remove the asr, and change the cable and im good to go? im sure ill get the lights on the DIC but i can just take the bulbs out. as long as it doesnt affect abs or engine, then im good to go! thanks, and god damn your engine is clean!

Glad I can help.

Again, the car's not on the road just yet and the new throttle cable hasn't been hooked up to the gas pedal just yet, so I'll only be able to give a full report once everythings back together - BUT, from all the info I've gathered, an Fbody cable is all you'll need to get up and running.


Forum member "RUKWKR" deleted his ASR box and claims that his ABS still worked, though he did mention having to remove the bulb in the DIC and disconecting the ASR fuse.

The plastic clip on the throttlebody side of the cable (which secures the cable to the bracket located on the side of the intake manifold) was slightly different then my stock clip, but popped into place and secured the cable to the bracket just as well.

Aside from that, all I can add at this point, is that pulling the cable through the firewall was a bit of a chore. The throttle cable slides into the car via a small square opening in the firewall. Once the cable passes a certain point, a pair of small plastic clips "pop out" and basically keep the throttle cable firmly attached to the firewall.

Before you can slide the throttle cable back out towards the engine bay area, you'll have to go into your car with a set of pliers and try and reach up and "pinch" these two clips together, in order to push the cable back out through the firewall. It sounds easy, but it's a bit of a pain to reach these two clips because the foot-well area is so cramped.

By the way, you'll need to remove the hush panel under the dash in order to gain access to everything, but that's just a few small screws. No big deal. I'll let you know how I fared once everythings together again.

Abs will still work. I took it out for a rare ride in the snow this year. LOL. You need to pull the ASR bulb out of the dtc panel. The throttle will not open all the way without adjustment. I used a 1 inch piece of plastic cable off the asr throttle cable, split it, and attach it to the pedal side cable with zipties. This effectively shortens the cable.

I have a holley throttle body so it had all the right fittings to bolt right up. I used a 90-91 cruise cable and it works but I had to do some cutting to make it work on the throttle body end. Cruise control still needs adjustment as it is not as smooth as stock. Engine bay is much cleaner and easier to work on.

The f body cable sounds like a good fix, but you can easily make a cable yourself. I used a bike brake cable...but it's probably easier to cut the appropriate length from the factory cable.

Get some garage door stops (little crimp on metal slugs), check that you get full wide open throttle, and set the length. Crimp a stop on the end of the cable at the pedal and test it.

To answer the other part of your question, removing ASR will not change ABS. It is a stand-alone mechanical system vs an electrical control system which controls ABS.

Will not work for OP, his is an electronic tranny, 92 is not.
It can be done, but it is not easy. I guy did it in digitalcorvettes, but as I remember, he rigged his car.
Personally, I hate the thing, but it is a pain to get rid of.

i ordered the 93 camaro throttle cable off of hawksthirdgen. removed the asr and all cables, then installed the camaro throttle cable. had to shorten the cable slightly, or else i would not get full throttle. was very easy

Cool, how much did you have to shorten the cable? I have no asr so I was just trying to figure away around it. So theoretically all I should have to do is pull the fuse remove the bulb right? My car was a theft recovery and im just trying to build it back up and get it on the road.

Just curious what the ASR actualy does other than push the pedal back at you like the car is telling me TIME OUT!
If you don't need it for ABS or traction control then why did they put this worthless thing under the hood. It took me about two days to figure this thing out when I put my engine/trans back in the car and had to adjust the TV cable, throttle (new throttle body) and cruise control
