Ported TB pics and tune adjustments
#22
Here is what the table looked like stock, vs Stock TB tuned, vs Ported TB tuned. I fudged the values in the extremely High and Low temperatue settings based off of average % error. There was no way for me to get my engine coolant down to -30* or up to 284*....
Kinda interesting when you look at the results... BTW this is the same procedure you use when tuning a cam with low LSA.... Very small changes to this table make BIG changes in the way the truck idles....

I will be removing the MAF completely today and installing a fast reacting IAT sensor like the FI guys use and a Hump coupler where the MAF was.... I will probably have to repeat this entire process again after that, from what I have read on EFI Live forum. Then I am going to retune my VE table. I will post up some before and after VE tables when I retune this weekend too.... Then off to the track to see if I gained anything from the UDP, Ported TB and MAF delete....
