Vern, their website has little info at present so can you tell us how much $$'s, are all function sensors included and what is the accuracy of the data it provides, please?
Here you go.
https://www.madman.co.za/index.phpMadman is made in Africa initially for Landrovers by a landy tragic.
I am running a EMS1 in my Disco 2.
Monitoring Egt's' coolant temp, gearbox temp, voltage, hours, and oil pressure. These can be all brought up on one display or you can toggle through and monitor them all individually. It is also monitoring low coolant as an alarm.
The alert alarms for over or under range and is quite loud and the display will default to what is running out of range.
I bought mine from this sight in Africa approx 4 years ago with all the sensors included. Cost around $ 500 including postage from memory.
Highly recommend the unit. If you get one ensure you follow the installation instructions otherwise you will have issues with false alerts from bad earthing issues Don't ask how I know.
I am considering swapping my oil pressure to boost . Unfortunately the unit can't monitor both at the same time. Still deciding on that one or whether I should run a seperate boost gauge.
Cheers Chris
