    VTECH Datalogger Values Definitions

    Anyone able to right up a quick definition for each value on the vtech datalogger? Would be nice to know what your looking at and not think that's what your looking at.

    I see this request never got answered but I am just starting to use the logger and would also like to know the definitions of each measurable value and the differences.

    e.g. what is the difference between 'basic ignition angle' and 'ignition angle'?

    I guess you get one single answer in short time - but only one. BET!!!!

    It would be nice to have since there is no formal instruction on it. over time iv just figured out what they do weather im right or wrong who knows its running!

    On the ignition side of things, I only tend to look at Ignition Timing 1,2,3 I view them in MLVHD with the limits set on all three at say 5min and 45 degrees max. If they are all within a degree or so, most likely you are ok.

    Basic is your intended base ignition map without corrections.

    Actual ignition timing for each cylinder is more useful like whittle did mention.

    Whats the V-Tech value for fuel pressure? Just so I can match it up to what the RRFPR says.

    You need to wire it in.

    The stock ecu doesn't have a sensor for fuel pressure.

    You can add it on and even set an alarm for it if pressure drops.
