I went drag racing this last weekend with my 2005 hemi 2wd. I tried turning off the overdrive with the button on the shift selector but the overdrive kept coming on at 5200-5300 rpm. Does anyone know how to keep overdrive from kicking in until at least 6,000 rpm? I have a Diablo Trinity and the only shift points I can see that you can change are the 1-2 and 2-3 and not the overdrive. By the way I ran 14.02 but I think I can get into the 13.80's if I can keep it from going into overdrive. Any helpful tips would be appreciated. Thanks.
I am running 4.86 gears with a 28x10 slick on a 17" wheel. I was trying to figure this out last week racing and I never considered shifting back down like that. I will have to try that this next weekend. So I am assuming then that there is no way to set that shift point of over-drive by the trinity I have?
Yes, but it shouldn't have shifted up. I was no-where near out of the power band. If I can do 4200 rpm at the finish with 3.92 gears, there should be no reason I cannot be at 5500 in 3rd gear at the finish without going into over-drive. Now if I was at 6400 at the finish line I could see hitting over-drive!
1.96 on the 60' and 8.93 in 1/8.
You have 213k on the odo? WOW! Maybe I will keep mine for a long time.....
