Replacement for Sport Chrono clock

What is it and why do I want one?

Anyone who has the SportChrono option in their 997 or 987 is probably wondering what to do with it. I found it 100% useless. So, I decided to make it useful.

It is an instrument that replaces the SC clock. Because the analog instruments for oil temp and water temp in the dashboard are less than accurate - and sometimes hard to see (oil pressure) - or not present at all (987.2) - its main purpose is to give you accurate readings on coolant temp, oil temp and oil pressure.

How does it work?

The device has 5 modes (see pictures) and here is a short video where you see the device in action.

• Mode 1: analog clock
  the clock is reading the time from the Porsche ECU via the CAN bus and will always be in sync with the clock in your Porsche

• Mode 2: analog clock but with two additional dots at the top and bottom, that indicate the oil temperature (top) and coolant temperature (bottom)
  The dots move along the dial and change color (blue/green/yellow/red) based on temperature
  I am now offering an add-on which allows you to see the car’s voltage in “Mode 2”. If the voltage is in normal range, it’s displayed in green. If it’s outside normal range it’s red.

• Mode 3: temperature display (simple)

• Mode 4: temperature display with bars, which change color based on actual temperature

• Mode 5: oil temperature on top and oil pressure on the bottom (you can finally observe your car’s oil pressure without having your view blocked by the rim of the steering wheel!) - or if you have a 987.2, you finally have access to these two vital pieces of information about your car’s health right in your SportChrono wart.

You have the option to configure the display so that it does only show the modes you want to see.

You are also be able to switch the temperature between Celsius or Fahrenheit.

The module also has “memory”, meaning whatever mode you had on when you turned the ignition off, will come on when the ignition is back on.

All data is read directly from the ECU via the CAN bus, that means if you adjust the clock in your dashboard you also adjust the clock in this device.

I like to keep things simple and decided against additional buttons to control the device. The different modes are either auto-selected (for example when you select "Sport mode") and can also be switched by "double clicking" the PASM button. In case your car doesn’t have PASM, you can control it via an external push button.

Of course the device will dim it's backlight when the headlights are on and it’s dark outside.

How difficult is it to install?

The difficulty in installing this is 3.5/10, please read the installation / user manual (in the Documentation section of this site), to understand what needs to be done and then decide if you feel that you can do that. Owners of the device have reported back that it took them 1 - 3 hours to install it.

Any caveats or gotchas?

• Your car needs to have the SportChrono option (duh). But there is also a version of the device available in the store for cars without SportChrono.

• The following models are supported:

  • 997.2 Base

  • 997.2 S / 4S

  • 997.2 GTS

  • 997.2 Turbo and Turbo S

  • 997.1 Turbo

  • 997.1 Base

  • 997.1 S / 4S

  • 987.2 (all models)

  • 987.1 (all models) supported with limitations (see below)

• You need to physically tap into the CAN bus (please refer to the manual for details)

• I am now offering an add-on which allows you to see the car’s voltage in “Mode 2”. If the voltage is in normal range, it’s displayed in green. If it’s outside normal range it’s red. This add-on can not be retrofitted.

• Limitation for the 987.1: Oil pressure (for the 987.1 a modification on the car is needed, either read the instructions here and/or refer to this video, start at 8:19 in the video)
