Hi
I was looking around for best engine monitoring system for landcruiser.
The issues I am having with my HDJ80 from 1997 (with manual transmission) are

  1. Gauge readings in dashboard are no longer precise, esp. oil pressure meter is always showing low (although there is no issue when checking it manually).
  2. Voltmeter is working, but I would like to see the exact value instead of just a visual indication. Also I want to see warning when it’s time to charge the batteries.
  3. Preferably only *one* unit which can make all the required measurements incl. associated alarms and warnings.

So instead of spending time & money on diagnosing issue and possibly fixing dashboard, I am raising this issue in forum.
Any suggestion is welcome.

Peter

That's interesting as I have madman too and the issues I had were poor earthing for the sensors by the installer and if the earth points are not completely fantastic, it can give some erroneous readings e.g. I found the power windows were changing the boost pressure and I was testing it a lot with my old rubbers and managed to pull the window out of its actuator - doh. Madman are very approachable via email though (Brian Cotton). I do have an installation guide and a fault-finding diagram if you want them [PM]. Charlie which sensors proved to be duds with you? Brian told me the sensors can fail but by far the largest issue was bad earths.

Does anyone have the diagram showing the proper position for those sensors of HDJ81? Oil pressure, oil temperature, ...

also, did you install the air fuel ration sensor?

Thx

Hi All!
Now my concern is the setup/ installation of those sensors! Would it be replaced the original sensors and connect to the non-factory monitoring system for HDJ81V? I don't think that it would be! Thanks.

Currently making my own temperature monitor for mine, just a fun project at the moment to measure engine, A/T, and diff temps. So much stuff out there is for OBD2 cars only, and the Prado 90 series at least here in Australia is not an OBD2 compliant car - only became mandatory here in 2006 or similar.
