I searched around for a few days looking for this info but havnt found it. When i see peoples settings thet say they set there WOT shift points to 5100, 4800, etc.

When i look to set up my Edge CS i dont, or cant find, these settings. I do have a shift point changer but its not for WOT or at least doesnt specify it, and it is edited via -MPH. so i can change the shift point from 1 -> 2 as -2 MPH.

Is this equivalent to what others see? do i need to chang something? and does this effect WOT, normal DD, or both?

Thanks guys and gals!

 

You don't have a WOT shift point change option in the CS or CTS. It's something that Edge decided you were better off not having. You CAN increase/decrease the Max RPM point, but that's about it. I would not set it above 5600, since the torque converter starts to balloon above 5400.

The WOT shift option was available in the older, monochrome Edge Evolutions. I suspect Edge decided people would set these values too high, and damage the transmission.

You can still change the part throttle shift and torque lock/unlock points. That is something you might want to do to improve normal driving (more power or increased fuel economy).

Jack,

Thanks that clears some things up. Sounds like the Evo would of been a better bet. Are you aware if the shift speed change is for WOT or juts in general? Also does anyone know how to correctly get the Torque converter set to lock in? i was playing with it last night and regardless of where i set it i feel like it always locked around 40 MPH, and it was a little jumpy around 35-39 mph.

any info would be great!

Thanks,

Max

 

The shift points you CAN adjust, and the torque converter lock/unlock points are called "part throttle" settings. This means they are dependent on vehicle speed AND the throttle opening. Actually, they really depend on engine load, so the speed thing is kind of "fake".

Setting the upshift points (when the transmission goes into a higher gear during acceleration) to positive values (+2, +3, and +5 are the limits) delays the upshift until you reach a somewhat higher speed, keeping you in a lower gear longer and supplying more power. But, if you ease off on the throttle, the upshift will occur sooner, since the engine load is less. Setting these values to negative ones causes an earlier upshift, which CAN improve gas mileage.

Setting the downshift points causes downshifts to occur sooner if they are positive and delays them if they are negative. So, if you start climbing a hill and have to add gas, you should get an earlier downshift if the settings are positive, and it should be delayed if the settings are negative.

Personally, I feel the transmission downshifts too soon, so I set all those values to the maximum negative settings. Similarly, during acceleration, I want the transmission in the highest gear as soon as possible for economy, so I set all the upshift points to the limiting negative values too.

The Torque Converter (TC) works in a similar manner, except there are four settings each for unlock and lock. Unlocking the TC provides more power to the wheels. Locking it reduces engine RPM, which can improve economy. I want mine to lock up as soon as possible during acceleration, so I've set all the lock points to the maximum negative values. And, I don't want it to unlock too quickly during small engine load increases so I set all the unlock points to the maximum negative values too.

Overall, I have reduced transmission activity when cruising using these settings.

If I "floor" the accelerator (that's WOT), the part throttle settings are no longer in play. I still have the factory downshift and TC unlock behavior, so I have full power for passing on the highway. If the WOT shift points are set too close to the max RPM, you can hit the rev limit if you keep the accelerator floored, which causes an abrupt loss of power when the engine "cuts out" (ignition and gas supply are killed). You can ease off the accelerator a bit to allow the upshift to complete if this happens.

I think you get flaky TC behavior if the unlock/lock points don't match. For example, if you set, say, the lock point for 4th gear to +10 for more power and the unlock point to -10 it seems to cause "confusion", for lack of a better term. I think they should all "match up" and, I think the "direction" (positive or negative) should match the shift point direction.

Hope this helps, Max.
