Overdrive comes in to soon Just got my car re-tuned. the tune was tweeked slighly and added another 20 HP, so no big changes were made. One change was I went from 26" tall tire to 28. now my car shifts to overdrive at about 40 MPH which is to early in my opinion. if your just easing into it on the interstate not much of a problem, but if your under half throttle acceleration the car really bogs when it goes into overdrive, and if your cruising round 45ish the car lugs like a manual in to high a gear. Above 50 runs fine. All other shifts are great. I had this problem when I switched gear ratio and had it tuned out. I now have HP tuners so I was wondering if I could tune it out. Keep in mind I am new to HP tuners.

Take a look at the part throttle shift speed table under the transmission menu. You can set the shift speed to whatever you want versus throttle percentage using those.

Why would you go to a toggle switch that you have to constantly turn on and off every time you stop and go, when you can take a few minutes with a laptop to tailor the shift point throughout the throttle range to do it automatically? Do you have to use the button to shift your Mazda into overdrive every time? No... it is there to disable the overdrive in conditions when you don't want it, such as slippery roads or hills... but when you do want it, the computer shifts it at the proper point.

Good god 
OP, the tables will allow you to custom tailor your automatics shifting parameters. Or just drop it in D during lower speed driving where it is posing a problem.

ha that is backwards since it takes 30 seconds to change the TCC table and 25 seconds to rewrite it in the pcm.and if i dont want my Converter to lock i hit the Tow/haul button/Performance button that was also tailored to my liking Via the TCC tables.

The write up from Coolaid was very good, best article I've read on this subject and I thought I had it figured out. But like I said, I just got the HPTuners and am not that proficient with it yet. I understand what he did but, when I tried to copy my data from the WOT shift speed 100 boxes into the Shift speed vs TPS vs Shift normal 100 boxes the only boxes that changed were the 100. how do you figure out what the others would be (94,87,75, etc). I kinda see that he subtracted the same amount of change to some of the lower boxes, but how do you figure that out? Could I just play with the 3 to 4 shift , because that's the only problem I'm having.
