    I think I got it now.

    I ALSO tHINK I NEED TO LOG MORE TABLES - when I copy over to the B0101 table its nasty looking dips and jumps in the graph - I think I will try again tomorrow and wait for some responses.

    Does 36 degrees outside affect what im doing or trying to do?

    Log for longer... use smoother progressive throttle, don't yank it open... use brakes to induce more load.

    You have 27 pid channels (which reduces the sampling rate from 10 frames/s to 5 frames/s).

    Is this from doing AutoVE or CALC.MAFT...?

    Yes I noticed that also I will change them to 22 channels to watch.

    Hey, in regards to log 2 I have some observations. At times it looks like your narrow bands diverge from each other. At frames 2108 you can plot and see they follow each other nicely, but then you see at 2198 and 2239 that they completely diverge, one says rich other says lean. I think low mV means low of stoich, and from there you can see that the WB02 agrees mostly with H02S11. frames 2510 to 2726 have good cyclic behavior around stoich and the WB agrees.

    What I don't see is your CALV.VET map or pids. It might be how I download and open your tune but I don't see that you have collected them. can you confirm that you are indeed making the map with the parameter names calc.vet, calc.ven and calc.cl?

    Yes I have the calc.maft pids selected right now. The second sticky down. Should I being different?

    At first I had calc.vet plus some autove pids plus others I accidentally saved as joe car pointed out.

    I must need to setup more maps to log if I need calc.ven and calc.cl I didn't see how to do that part

    Thanks for all the help!!! I'll be looking at the log tomorrow -

    Make sure your transient filter removes those WO2LAM1 excursions above 1.4 or 1.5.

    Post screenshots of you maps.

    With Calc.MAFT you are correcting (paste-multiplying) VE table, and calculating a new MAF (pasting)... ignore the MAF part for now, concentrate on the VE table.

    In the log, look at WO2LAM1 to see if it makes sense... CALC.CL tells you whether LTFT's or WO2BEN are to be used for correction.

    this is my ve table before I paste with multiply - something just doesn't seem right at all
