Near my house is a 2-3 mile straight stretch of 4 lane road, speed limit 45 and it has nothing on either side but grass and retention ponds. I made multiple passes at different speeds to try and get the fuel injection to self learn, and it did pretty well. Made a few passes at 35, another at 45, another at 55 and a couple winding through the gears with high shift points.
The only issue I have to adjust is the Decelerate Fuel Cutout, as I am still getting some popping in the exhaust when I decelerate. It is not nearly as bad as before, and only does it when I wind the engine up to 3500 - 4000 rpm then immediately decerate by closing the throttles while still in gear or downshifting at high rpms. The DFCO was factory set at 30 and when it was popping a little, I set it to 50. Looks like I went the wrong direction because the popping got far worse. I dropped it back down to 30 to see how it worked after driving it a bit. Still popped, but not nearly as bad. I plan to try to drop it down to 20 today and try again.
FiTech wasn't very helpful with this, as the tech rep told me that my engine with side exhaust should expect the popping due to the short exhaust pipe length, and that I should just deal with it. I essentially told him to shove it and that he should get out of the Customer Service business as I didn't think FiTech or any other manufacturer would make a system that did this while everyone else's did not, including factory equipment.
I got the info I needed on Youtube (you can pretty much find anything on Youtube!).
Well, gotta go to work now, but more after today's run after work.
