REVELTRONICS

Hello, I just purchased a UTCOMP PRO.

For turbo boost I have the Bosch 5V 3 Bar MAP sensor.

For oil pressure I have 150 PSI/10 Bar 5V pressure sensor.

For oil temp I have Oil and Water temp sensor NTC analog.

I would like to confirm wiring for these.

For MAP SENSOR:
Positive to VCC (A6 or A18 or B6 or B12)
Ground to GND (A4 or A16 or B4 or B10)
Signal to Adc1-4 (A8 or A9 or B2 or B3)

For 5V OIL PRESSURE SENSOR:
Positive to VCC (A6 or A18 or B6 or B12)
Ground to GND (A4 or A16 or B4 or B10)
Signal to Adc1-4 (A8 or A9 or B2 or B3)

For NTC ANALOG OIL TEMP SENSOR:
Positive to AdcVcc1-2 (A20 or B8)
Ground to BODY GROUND

Are these correct?

Yes it is correct

For MAP and Oil pressue sensors you can also use vehicle ground if you have good connection point next to sensors.

Thank you, I appreciate the very quick reply.

Additionally, I would like to display coolant temperature on UTCOMP PRO, taking data from existing coolant temp sensor.

I understand I can tap positive line of existing sensor and attach to Adc1-4, but I must scale for output to be correct.

Would you happen to have data already on my existing sensor to scale it properly?

This is for a 2010 Subaru Legacy 2.5 GT 5EAT, but the sensor is probably the same as all Subaru 2.5 EJ255 turbo models.

If you have diagnostic interface then the best method is to make readings (voltage on sensor + temperature) and then you can use these readings to scale it with utcomp. Please take a look for excel calculator in first post: viewtopic.php?f=28&t=58

If you do not have diagnostic interface then you can read temperature from dash and voltage from voltmeter. It will be less accurate (because you can not read temperature below 50-60C) but it will work too.

ps. voltage on sensor is also visible in UTCOMP app (readings tab)

I will review the link and give it a try, again, thank you.
