When I did an auto tune, one entire row in the VE table was left blank. This row is somewhere around 50% in a 16x16 table. The screen that shows which cells have been changed has a blank line right across the center. Of course I went back in and changed them manually to create a smooth transition from one cell to the next. The question is: WHY? Is there something deffective in the hardware or software? Does this row of cells get ignored by the map when running in closed loop? I did the session in 45 degree weather, and was surprised that it made everything so much richer. I thought the IAT compensated better than that.things were increased by as much as 20% in some cases. The engine did not operate in all cells, so some are clearly still wrong. I wonder if it would be smart to increase entire matrix by 10% to start a "Fall" auto tune? Sam |

No idea on the row drop. I am still using stone age MS1 software (megatune 2.25) and have never used autotune. My experience is that IAT sucks for our application. I recall there is a way to change the slope of the correction factor, but I've never bothered. I think it's easier in the later versions of the software. Lou |

The 3.3.0 and later MS2/Extra codes have the IAT correction editable directly; you'll want to upgrade if you don't have this already. Get a good VE table at your current temperature, then tune the IAT correction when the weather changes. Can you post the data log of what was going on when it missed a row, or email it to me? |

I think mine is 3.47. So it should be editable, but would not have a clue which way to change things. I think you just told me, but i would not know the details of that process. The correction apparently needs to be more aggressive. Do I start the autotune before the data-log? I have always been vague about the sequence of button clicks to start and save a data log. Sometimes I luck out and get it right.  Sam |

Start the log first. |
