I have pro sport gauges/senders for my drive and boost gauges. They use an electronic sender that is 3-160 ohms. I would like to be able to log the boost and drive pressures with the scan tool.
Would it work if I made a voltage divider circuit with the sender being one of the resistors and a 20 ohm resistor being the other resistor? I would use the +5V regulated supply from the ECM and then use the V2's analog 0-5V input to measure the voltage across the 20 ohm resistor. From my calculations, that should give me a range of .55V - 4.0 V.
Anyone got any thoughts on this? Is there a way to correlate the 0-5V that is sent to the V2 into some other value in the scan tool? (i.e. .55V = 60 psi)
Thanks
Chris
