Cruise control unit

[rficalora]

Anyone know if the AudioVox CCS100 is a good choice for cruise control?  I know several people have used the AudioVox units & like them, but don't know if there's more than one version/model so don't know if that one is a good one.

There's a guy on the MGB Experience board who bought some from an auto parts store that's shutting down & he's selling them for $80 including shipping.

Rob,

That is the standard universal model. It is a good unit. Do a search on the main MG forum over there. I remember that the stock 4 banger MG guys have been using the CCS-100 for years. I see them going for $60-$95 on Ebay.  I believe there is a model with a smaller actuator now. Some have an electric actuator. Sometime a vacuum reservoir can is needed for cars with big cams,  just like for power brake boosters.

I paid $25 for my NOS "antique" Sears cruise control.  It was made by Rostra. I tucked the actuator can mostly into the fenderwell hole over near the washer fluid reservoir.

I installed the AudioVox CCS100 several years ago and it has worked great.  I have the control switches mounted in the ash tray and raised them up about a 1/2 inch using a small block of wood.   At the time (~2002) the AudioVox unit was the smallest, easy to hide and install.  

I did discover that the AudioVox cruise control needs to detect a light bulb in the brake light circuit or it won't work.  LED brake lights will not allow the cruise control to engage unless you add a resistor in parallel.


Here is my web page on the installation

How does this unit measure the MPH does it have a magnet/weight on the driveshaft?

MPH is measured using engine RPM with a connection to the ignition coil.  The cruise control kit also comes with a magnet and sensor for the drive shaft.  I an using the tach/ignition coil method and it works great, fewer wires to deal with.

I presume that measuring actual speed (at the driveshaft) is only advantageous on a car with an auto transmission. If you use the clutch to change gears the cruise control will automatically kick out anyway, right?

Yes the only time you would want to use the drive shaft sensor is with an automatic trans.

When the clutch is disengaged the control senses a sudden increase in enging RPM and releases the throttle.

I'm guessing that if you had an automatic with a lock-up torque converter (like Steve's 700r4) then you might get by with the tach sensor? It might act a little flaky if you didn't have the lock-up engaged though.

The AudioVox CCS100 can also be connected to the VSS.

Mine is an older model cruise packaged for Sears.  I used the driveshaft magnet. The clutch does not affect it since I didn't put a switch on it.

If the only input came from the coil then it would only hold RPMs not mph and I assume you would only use it in a set gear example how would you go up a steep hill with an auto trans?

 The VSS sensor is what I was hoping to hear.
