Datamaster Question
I am new to datamaster and have a question...
What is the Datamster "Fuel-Air Value"? I thought it should be 14.7:1 or something close. It shows a value of 446 and briefly 547. Does this value make sense? I'm :confused:

Re: Datamaster Question (capkwk)
you are thinking of Air/Fuel Ratio. but to answer your question, I dont know. I have heard of Fuel/Air ratio, but the number that you quoted does not seem to be a real one, in that context. What app?

Re: Datamaster Question (capkwk)
I've just started using DataMaster myself and noticed the same thing. The doc seems to indicate that it's the air/fuel ratio. But the cell description says "Total Fuel-Air Value, Units=Ratio". Mine sits at 445 most of the time except when you go WOT, then it jumps up into the 550-560 range. Similar to what you see. I think we can guess that 445-6 is 14.7:1 but I have no idea why it reads the way it does or why their documentation does not explain it.
The cell is described in help text as -
Target AFR (Air-Fuel Ratio)
Target AFR indicates the Air/Fuel ratio that the PCM is trying to control to. Generally, this is only different from 14.7 during warm-up, full throttle operation, and highway economizer mode. Not available for all PCMs.
