Here is a MAF table for fully ported MAF with a lid Here is my contribution for today. The Excel file is a MAF table I put together using a Z06 table, some cell shifting, a few percentage changes across the table, and adding a small amount of airflow across the table to put the values slightly negative. I have been testing it out for a week or so. I can't really find any way to improve on the table because it has worked out so well. Since it is supposed to put your trims slightly negative, your trims will need to learn a little. The table was made using a stock MAF with Thunder Racing MAF ends and a SLP lid. You will see some slight variance between cruise and decel (maybe slight positive LTFTs on decel). This can be attributed to the difference in airflow across a screenless MAF with the throttle blade closed. The only way you might be able to correct this is to monkey with the airflow filters and bias it more towards VE, but I doubt it would be worth the effort. If you have been trying to re-calibrate, then please test this out and let me know how it works out for you.

If you only had an automatic so the pressure tables could be adjusted as well. The experts say that the tranny pressure changes with a ported mass air body. At least this takes care of the fuel changes. Thanks...

Will it be ok to up the pressure while spraying thru shifts?

On my 1-2 it took two frames. 2-3 it took 6. I upped the pressure 3% on the 2-3 and the count went to 4. I don't know what is right but two less frames should be less slippage.

But I think I have mine nailed down, everything is between 0 and -4.
