Hondata

I am interested in purchasing a IQ3 dash for my EM1 hondata s300v3 .
which parts do I need to make it work?
do I have to buy all these expensive sensors to be able to see oil pressure, oil temperature, actual water temperatures, fuel presssure, fuel level?
or is this dash compatible to atleast display what the ECU display when using a laptop?

very urgent and important question.

See http://www.hondata.com/help/kmanager/ra ... output.htm

The IQ3 can only display the channels that the ECU reads and that are also converted by the 230-VM-EFIHOND. This oil pressure, oil temperature, fuel pressure, fuel level are handled by the IQ3 and whatever interface you choose for it. The water temperature is a 230-VM-EFIHOND channel and will be present in the IQ3.
