So my I have been driving my 4.6 since Febuary and was hoping to decrease the shift points, as now it shifts at 2300rpm and since I like to drive like a grandpa I would like to decrease these shift points to about 2000 or below.

If I installed an edge programmer, would I be able to adjust this?
Is there any type of chip that lowers the shift points?

My truck only has 33's on it so its not like it needs the power.
Thanks in advanced for your help,
Carl

 

Yup, you can do that. But the Edge lets you change "normal" shift points according to speed, not rpm as I recall (which seems a bit weird).

You could do the same with a Gryphon, and Bill could write a special "Grandpa" tune for you.

It isn't weird at all, it works best that way, as that is the way FORD designed it.

 

Okey Dokey - I'm not being a smartass here, just asking a simple question: "Why"?

Somehow, engine RPM, which relates to torque output and efficient engine operation, seems a better choice.

Back when I could still get manual shift vehicles, I shifted on engine sound (RPM), not speed. More simply put, if I sensed the engine was getting near where it was starting to "lug", I shifted down. If the engine seemed to be "racing" and it felt like it was approaching a "no pull" state, I shifted up.

The net effect was that I kept the engine in a rather narrow RPM band where it seemed most "happy". Speed had nothng to do with it.

Wish I could still find manual shift transmissions in the vehicles I want to drive. (You could even push start them with a nearly dead battery, and you could "rock" them easily if you got stuck in the mud).

So anyway, why choose speed instead of RPM for normal shift points?
