Hey everyone I'm curious about the ignition timing on my base 93 940. I'm interested if the ignition timing can be independently altered or if it is altered by the MAP sensor.

Additionally, does the MAP sensor for the 93 940 Regina system function off of frequency or the 5volt system such that when the engine is revved the voltage from the sensor increases or decreases.

Thank you for your answers in advance

Hi. I have the Volvo Greenbook for the 940 Regina system on .pdf. If you pm me your email address, I can email it to you.
