Calc.MAFT: correcting VE and calculating MAF (in single log) --> reverse of Calc.VET

[WeathermanShawn]

In-Memory-of-Shawn-Sankey

This is the reverse of Calc.VET

This requires the OS to support the pid GM.VETABLE_DMA (unless you're SD/MAF-less in which case you're only correcting the VE).


AIMS:

Tune MAF/VE tables from idle to redline RPM in a single log session:

1. Tune both CL and PE/WOT,
2. Correct VE,
3. Calculated new MAF from corrected VE,
4. Eliminate Trims.


PROCEDURE:

1. Disable MAF: CALC MAFT can be performed Open or Closed-Loop

A. C2901: MAF High Frequency Fail 1: Change to 1 Hz
B. C2903: MAF High Frequency Fail Limit: Change to 1
C. Copy B5913 High-Octane Spark to B5914 Low-Octane Spark
D. Insure MAF Sensor Circuit is displayed as a current DTC


2. Setup Calculated PIDS:

calc_pids.txt <--- updated calc_pids.txt file

Copy that calc_pids.txt file to this folder, or copy/paste its contents to the calc_pids.txt file at this folder on your PC:
My Documents\EFILive\V7.5\User Configuration\


3. Select the following CALC.VET pids and record a suitable log:



Note: Keep Channel Count at 24 or less for Fastest Scanning.

Note: CALC.PE has been replaced by CALC.CL.


4. Apply CALC.VET/MAFT Filter:




5. Paste-with-labels the new CALC.MAFT map into Table B5001 in your tune file:

( ignore this step if you're running SD, i.e. ignoring MAF and doing VE table only )



(to limit the cell display width to something sensible, in the map properties goto the Cell tab and look at Constrain Cell Size)


6. Paste-multiply-with-labels the new CALC.SELBEN map into Table B0101 into your tune file:



To display units on a map: go to map properties, on each of the Data, Row, Col tabs, checkmark Show Units.
