    Default Newbie looking for advise with first tune

    Hello all,

    I am new to this tuning game and would just like to run everything past you guys before I make to many changes. My car is a VE Holden Calais with a L98 and A6

    I have started by following Swingtan's tutorial on VVE setup.

    I did some logging to set up the IAT injector flow modifier table. The first log is factory and the second one is a modified tune. The final tune is running a lot flatter but is still a tad rich, Should I keep trying to get it closer to commanded or will it be OK???

    Any help greatly appreciated

    Ben

    Running rich is not a big issue, at least not when setting the IAT correction. All you are trying to do is get the WB signal to indicate a constant combustion AFR over a wide range of IAT readings. You are pretty close looking at the second log, though there is a bit of a step at 66' IAT, but over all it's quite good. You can get the correction closer if you want, then go on to work on the VVE its self. This will bring the WB AFR back towards the commanded.

    Thanks Simon

    I didn't know if the AFR had to match commanded or just be flat all the way though the temp range.

    The step was when the Hi speed fans cut in

    Yeah, I noticed that, as the MAP and air flow changed. But the AFR line before that was on a steady richening up slope, not a lot though.

    Is there anyway to adjust between segments ie in increments of 5 degrees instead of 10???

    Nope. I just did the settings at each 10 degree increment and the ECM will blend between them.

    The BEN data is there. You want "BEN Factor Bank 1, Serial Wideband, E38 style". Make sure it's selected in the PID list and then you should be able to put it on a chart / map.

    I should also add...

    • Try to keep a steady throttle when logging for tuning the VVE.
    • If you need to add / remove throttle, do so in a gentle fashion. No fast movements!
    • Get as much varying data as you can, hold it in first and take it up to 6000 RPM with very little throttle. Hold it in a higher gear and load it up. change up / down gears when cruising to mix up the data a bit.
    • Don't forget to filter the transient states out!
    • Get lots of data and apply, then log lots of data again.
