I've already created a topic about how I will use the analog inputs to build a complete data aquisition system and fail safe using a Hondata S300 V3.
It can be found in here: https://www.hondata.com/forum/viewtopic ... 19&t=18419
We are currently making all the wiring for the sensors.
We are using a relay conected to a 12v switched source wich powers:
4 channel EGT Amplifier - 5A fuse
Innovate LC2 - 5A fuse
Boost Solenoid - 10A fuse
12v-5v Converter - 5A fuse - The converter powers: Oil Pressure Sensor, Oil Temp Sensor, Fuel Pressure Sensor, Pre Cooler Boost Pressure.
Proper Grounding everywhere.
All the sensors including the EGT's were bench measured and proper calibration/voltage tables where constructed to compare against the manufacturers data.
Now the problem lies that the sensors output the correct voltage, it comes to the pins in the analog input conector but I cannot get any voltage reading in the software, not even when configured for raw voltage instead of a conversion tables.
All the inputs if made trough the ECU funtion properly (by the ELD, O2 or 2 Extra Inputs) but trough the 8 Analog Inputs we have nothing.
We have tried send 2.5v directly to the analog input using a external configurable power suply and no voltage shows in the software.
I can send you a diagram of all the wiring if necessary.
