Default comp driving mode retro fit?

Is there a way to retro fit the comp driving mode onto a 99 frc without the option?

Anything is possible but that would be a big job. Sensors on all the wheels and steering wheel. Plus the computer and interface with ABS unit. I'm sure someone else knows more about it than me though.

Competition mode is not what you'd need to install ... you'd need to install "Active Handling" (AH).

Once AH is installed, then you have the choice of three modes ...

All On (default at engine start) ... both Traction Control (TC) and AH are ON

All Off - push the button once and both TC and AH are OFF

Competition Mode (Hold button for 5 seconds) AH is ON and TC is OFF.

Now, to install AH, you'd need to install the accelerometer and yaw sensor in the cabin, plus wiring to power them and allow them to communicate with the EBCM (though the wiring harness may already have the wires in place). The EBCM would need to be upgraded (yours is probably part #09367071, and I believe you need 09376711), and the BPMV would also need to be upgraded. I'm not sure if the BCM would need to be changed or re-programmed too. You'd also need to install the steering wheel angle sensor (and possibly wiring), and I'm not sure without a wiring diagream if any relays and/or fuses need to be added to make this work.

The parts alone would probably run in the neighborhood of $1,500.00

The steering sensor is in the car already since the ABS needs inputs from the steering sensor.

Bill,

Help me learn, why does the ABS care what the steering wheel angle is ?? I thought it only looked at the wheel speed sensors for its operation.

That's Traction Control. Active Handling helps control the direction of the car by applying the brakes to one wheel at a time. AH needs to know what direction you want the car to go by knowing the steering wheel position and accelerometers tell the computer whether or not the car is facing the direction the steering wheel is pointed.

Read Bill's post .... he specifically said that ABS uses the steering wheel angle sensor .... which I don't understand.

The ABS and TC systems use the wheel speed sensors to look for wheels that are locking or are over accelerating. The AH system uses the steering wheel position sensor along with the yaw sensor and accelerometer to determine over/understeer. All of that I understand.

Bill's comment intrigued me as it implies that the ABS is more sophisticated than I had thought.

Sorry, I didn't notice that. Bill may know something that I don't then. It is my understanding that the steering wheel angle sensor is for AH only.

the more-accurate question would be:

Is there a way to retro fit Active Handling onto a 99 frc without the option?

I would think anything is possible.

You would need to gather a lot of parts like wheel speed sensors, tranny wire harness (speed sensor wiring on tranny harness), other sensors and re-program PCM.

I have not heard of it. If you're seriously considering this, start by checking to see if the wiring harness has he wires to supportt this. If it doesn't, then this would be a real pain to do ... if the harness supports it, then it would then "just" be a matter of getting the right parts to install.

Take a look at the connector to your EBCM ... going into the connector there should be the following wires in a row ...

Pin2 TAN/BLACK
Pin3 LIGHT GREEN
Pin4 Not Used
Pin 5 LIGHT GREEN/BLACK
Pin 6 LIGHT BLUE
Pin 7 Not Used

The key is Pin 5 ... if there is no wire there then the wiring harness does not support AH

Another place to look on the connector ...

Pin 16 Not Used
Pin 17 BLACK
Pin 18 LIGHT BLUE
Pin 19 DARK BLUE
Pin 20 Not used

Pins 17 and 19 are the keys here ... no wires and this will be a tough project.
