Internal map sensor calibration

Postby Screma » Thu Jun 01, 2017 2:30 pm

Hi all. I want to use the internal map sensor for my sprint 500. Everything is hooked up correctly and the engine runs fine but the map is reading incorrectly and not showing any vaccum. Just reads. -0.3 psi whilst idling??? When revved it increases the value further into the negative range??

I am convinced that its a calibration issue but the software will not let me change the map calibration table?? Any ideas?

The calibration is not adjustable. I would be checking where you are sourcing the MAP signal, that it is not from a ported source in a throttle body.
