200 series landcruiser trip computer

Yep, Just buy a Scangauge II.
About $160 and plugs simply into the diagnostic port under the dash. The gauge is mounted with Velcro on the steering column or dash. As well as all the fuel consumption stats I use it to measure coolant temp, transmission temp, voltage, air intake temp, boost, etc etc

You can do anything but it comes down to value for money and I don't think a dash upgrade would be cheap.

I haven't heard anyone doing it as yet, try the Lcool forum under 200 series.

Not sure if it's as good as a scangauge but if you buy an obd2 blue tooth unit $12 on eBay and down load torque pro app to android phone . This will read and do many functions from the obd port info..

Will also read and reset all fault codes which can help diagnose problems.

Cheers
