    Other then the idle problem I was asking why my calc vet table looks so crazy when i apply filters and input the data to my ve table. Im just trying to make sure i get it right. I have read almost all of the idle links. Hardest part about having all those links is one can get confused bout what was changed in there tune and what we should change back to default after tune is tuned. Also why am i geting a MAP performance code? Thank you for your help.

    No; the calc.vet procedure gets your MAF and VE nailed in one attempt.


    Can you post a screenshot of the CALC.VET map you used...

    did you do a paste of this into the VE table...?


    I'll take a closer look at your log files later tonite.

    Thanks for the help. I completed a longer fuller log and have attached everything. The air mass is definately different then the stock one. How do i fix all the cells I didnt hit in the log? I am trying to keep with 87 octane if it matters. Thanks again.

    Hey whackem04,

    Your tune is not really very safe; you are commanding ERQ= 1.0 at upto 90% TPS - this is very offen >95kPa MAP (effectively WOT)

    I'd suggest following the notes in the CALC VET Summary thread.

    Eliminates any Airflow Correction from the VE Table

    3. B3308: Disable DFCO: Change B3308 (M6) to 140C Change B3313 to 140C
    Accurate fueling computations

    4. B4105: O2 Switch-points to 450 Millivolts
    Smoother MAF & VE Table

    5. B3618: PE Modifier Based on Rpm (EQ): 1.16
    Safe adequate Fueling regardless of Fuel Type

    6. B3616: PE Enable: make sure PE enables as load becomes significant
    (e.g. below 60% TP below 3200 rpm, 35% TP above 3200 rpm).

    7. B3608 and B3609: PE Delay: set these to zeros.
    cheers

    So change the above run calc vet again and everything should be fine? I found Weatherman's base tune, should i start with that as a base and go from there?

    I'm running way behind... it will be another day or two before I can look at your files...


    +1 on what darcy said.


    Do not run 87 unless your compression ratio is 9.0 or less.

    B3608, B3609: set these to zeros.

    B3616: set this to 60% below 3200, and 35% above 3200.
