So, my idea about shifting based on RPM doesn't seem to work. I've tried the trick of setting the WOT shift speed to 0 and it still ignores the shift RPM table and looks at the normal throttle shift curves. So, I had to run a scan and use tap shift to find my WOT shift speeds, then play with them a bit.
Another thing that is interesting is the interaction between DOD and the TCC lockup points. When I set my TCC lockup points at a lower speed, I actually lost a bit of mileage when in DOD. DOD likes a little more RPM in 3rd, and by upping my TCC lockup point a bit I get better mileage. Since I made my TCC lockup more aggresive, you can feel the TCC lock and unlock when going in and out of DOD. This doesn't bother me, because when getting out of DOD I usually want to accelerate a couple MPH and letting the TCC slip a bit helps.
By the way, don't disable COT (Cat Overtemperature Protection) if you keep DOD. You have to tune sometimes cause it will dump a lot of fuel when the CAT gets hot and mess up your readings, but don't forget to turn it back on! Once the cat gets warm, it won't go into DOD. I forgot to turn it on before going to visit some family (3.5 hour drive), and I was wondering why I was burning so much fuel. On the way there, I burned between about 5/8ths of a tank. I reflashed, and on the way back I burned less than 1/2 a tank, close to 3/8ths. There wasn't a big change in elevation.
Finally, I think I picked some mileage back up from the LS6 intake swap. It seems to help a lot when DOD is active. I got maybe 1/2 mpg from the swap once I dialed in the MAF curve. When it was running really rich I lost quite a bit (1-2 mpg).
Sorry, no 0-60 times or anything yet. I'll run in the spring for sure. After giving in and springing for those group buy headers, I definately don't have any more hot rodding money for a while either.
