map sensor scaling/readings
« en: Enero 12, 2018, 01:52:27 am »

when the engine is off I'm reading about 102/103 kpa which id say is correct, however when the engine is started the engine hunting and I'm getting a reading of 102/103 kpa again
ecu isn't seeing any negative vacuum, however I have a standalone 4wd controller which uses a vacuum feed direct from the engine and its reading -35 to -20 kpa on idle whilst engines hunting
does this suggest incorrect wiring?

I didn't find the right solution from the internet.
