General Discussion / explanation of basic gauges ! importand
« on: May 10, 2012, 01:56:59 PM »
dear all hello,
i have my ug a couple of weeks now but i have the following questions about gauges:

1. the ug has the ability to show Air/Fuel ratio but it has 3 (!) options for doing so
a. AFR commanded ratio (value of λ requested by EngineControlModule)
b. Mass Airflow 1 (raw output from MAF sensor)
c. Mass Airflow 2 (calibrated version)

SO WHICH OF THE ABOVE SHOULD WE MONITOR ?? I'M TOTALLY CONFUSED
-------------------------------------

2. the ug has the ability to show throttle position as % but with 3 (again) gauges to do so
a. commanded throttle position (throttle position requested by EngineControlModule)
b. relative throttle position (relative ?)
c. throttle position (absolute output of throttle position sensor)

SO WHICH OF THE ABOVE SHOULD WE MONITOR ?? AGAIN TOTALLY CONFUSED
--------------------------------------

3. last but not least load in engine with 2 (this time) gauges
a. Load absolute (comments make no sense in manual)
b. Engine load (percent of engine load !!?? ...too simple)

SO WHICH OF THE ABOVE SHOULD WE MONITOR ??


P.S if someone knows what is the values of Ignition Timing Advance in a mazdaspeed 3 (turbocharged car) please explain , as in my car it is around 10 when engin starts and goes to 20 , 30, 38 when reving....
??
