ABS Is it possible to add?

[tyoneal]

Hello:

Is ABS something that someone can add to their car? If so, how, and who sells the parts for it?

Thanks,

It is possible; I know a certain vendor out there is working on a retrofit setup using a Bosch 8.X box as the centerpiece.

You'll need wheel speed sensors, etc. You could also try retrofitting a setup out of a 4th gen F-body (Bosch system) but I'm not sure about the lines of communications between the PCM and the ABS units. If you swap the complete powertrain it shouldn't be an issue, but I'm not sure about nor have I investigated the ability to use just the ABS box without the native PCM.

If you feel like digging and doing a lot of reading, search over at corner-carvers.com. Its been done, albeit on a Fox-body Mustang. Very good tech as usual on corner-carvers and if I remember right pretty much a step-by-step install with pictures.

Mungo retrofitted a Vette ABS system into his RSE winning AMX. From what I understand it is COMPLICATED.

Thanks for the feedback guys.

I think if you put certain Corvette parts on the car, wheel sensors would come with them, right?

I'm old tech (unfortunitly) and trying to get up to speed, so I ask:

EFI needs a computer to work, Computer controlling a 4l80e is the hot set up, ABS also need a computer. This being said, Is there a primary computer that communicates with all of these or, is there one computer that will control all of these, or does it just depend on the car?

What computer technology is available for the 1st Gen Camaro's?

Sorry about these being so elementary.

Thanks,

If you leave it to just the ABS and not use the TCS/AH it can be done without any interaction with the PCM/ECU.

So far, the challenge has been wheel speed sensors. The front are a piece of cake..... and the rear will soon be as well.

We know why the front WS sensor is easy now. Sooooo whats coming
around to help the rear be easy as well.

Could you tell us little bit more? I am really intrested. Would be easy for me because i have C4 bearings with abs rings all corners.

The physics behind ABS and ASR is simple, retrofitting it is another story. At the wheel there is a tone ring (ring with teeth) and sensor (permanent magnet and coil). As the teeth of the ring pass by the magnet, the magnetic field expands and collapses, generating an ac voltage in the coil. The coil sends the ac voltage to the EBCM which converts it to a digital signal from which it determines the wheel speed.

If the wheels lock up, the EBCM sense an abrupt change in the voltage and interferes with the braking. on the other hand if you loose traction, the computer sense an abrupt increase in voltage and interferes.

what makes it hard to retrofit ABS is getting the right tone ring and sensor that produce voltage within the range of the EBCM. Its also sucks that the parameters of most ABS computers cannot be changed.

Well, that is the easy part. 97 Y-body, Bosch 8.x EBCM with the 97-2006 wheel bearing cartridges.

Now there is lies the challenge. But it is possible..... especially if you have a Bosch Algorithm Engineer in your pocket.
