Digital Speed View

[Hilux2400]

My 2003 996 Carrera 2 has a trip computer in the bottom of the central rev counter. The speed is displayed digitally at the bottom of the speedometer on the left. The trip computer is controlled from a stalk on the steering column. The trip computer displays various stuff such as: mpg, av speed, temperature, remaining fuel.

Is it possible to set the trip computer to show current speed? It shows most other things, but whatever I try I cannot get current speed. It would be useful to display current speed here as it is easily viewed.

I remember driving a Carrera 996 in about 1999 and then there was a digital speed readout at the bottom of the rev counter. However, I can't remember if this car had a trip computer.

Thanks

I have never heard of anyone successfully hacking the OBC to display anything it doesn't already display. There are hacks to add an OBC control to cars without one, but that does not apply here. You're wanting the OBC firmware to display something it doesn't currently know how to display. Clearly, it has internal (software) access to the speed, but you'd need to do some clever firmware hacks to make it show it.

If your car didn't ship with the OBC stalk, you may find this useful http://www.renntech.org/forums/topic/22602-yousiefs-obc-hack/

The clusters changed in MY2001 and again in My2002 (USA version shown).

Thank you for your reply Loren. The layout that is shown for the 2001 car is the one I remember and the later 2003 layout matches my car. I thought at first my memory was playing tricks.

With my OBC there is a type of speed warning that allows a max peed to be selected and when that speed is exceeded the OBC shows just the max speed reading with an accompanying bleep. It would be great if the OBC could show a continually variable form to match the current speed of the vehicle and then bleep at the appropriate time. However, if that facility is not there I am not going to get it.

Thanks for your help and good wishes to you all.

That feature is not available for your model year, and you wouldn't want to attempt to retrofit an older model binnacle into yours.
