Fuel usage / economy guage?

[glen_ep Addicted PP Member Find all posts View Profile Close glen_ep]

I'm looking to install guages for several temps and fuel usage, however it seems the fuel may be challenging as a Scanguage isn't compatible with the 90 (perhaps there's no data in our computer for this?).
So how can we actively monitor fuel usage on the 90? I'm currently thinking a flow sensor... thoughts?

Have you had a look at PLX-DM100 or 200 series data reader and display......(hope I got the right one here)

A flow meter can be the most accurate, however as the fuel system has a constant return you will need something like the Flowscan system for diesels which measures the flow to and from the engine, then displays the difference (fuel consumption in other words).

Great system but expensive and you normally only get fuel usage not economy , litres per hour instead of litre per 100 km or whatever.

As I understand it the engine computer has the fuel parameters in it but one cannot (easily) access the Toyota ECU to read it, later engines use the more common OBD11 protocol which devices like Scangauge access for info.

Re: Fuel usage / economy guage?

Thanks guys. All these flow sensors and PLX fuel/air sensors are quite expensive! It's such a shame we can't just tap into the computer with a the usual ODBII connection. Oh well..
