Good Afternoon
I have a H22 EJ9 and iam wondering how I can get fuel and oil pressure feedback on the s300.
Kind Regards
Chris

From my online research it seems that this can be achieved via either the analogue or digital interface on the s300v3.
Analogue

Digital

So..... Any advise on which path to take.........

Analog would probably be cheaper and easier.

So I have my 2 analogue pressure sensors for fuel and oil which im going to run into A0 and A1 of the s300 and take the +5V and GND from the TPS or MAP sensor supplies to power the senders.
Do I need todo any mods to the ECU for this to work i.e. resistors/capacitors/jumpers
Thanks in advance

No you do not.
I have been trying to run the analogue sensors into the s300 but with no luck.
I have tried inputting a 1.5V reference voltage from a small battery.
The analogue gnd was connected to the 0v of the 1.5V battery.
I have set the conversion to raw data and tried inputting on Analog 0,1 and 2.
