Shift points under moderate load???

[twintips_17]

I have had an edge for about 3 years now in a 5spd f150. About 3 months ago I sold that truck and purchased a screw with the 5.4 and auto. My biggest complaint is that is seems to shift prematurely.

I have been doing some moderate towing in Montana and a lot of highway driving there and what i notice is that it will downshift at about %70 of a load on the engine. I feel that it should hold out a bit longer before downshifting.

I was goign to wait to have it tuned by PHP when i do my head swap but would send it in today if they could make it shift at %80 load.

What is everyones take on this?

Hi again -

You should be able to reduce the downshift speed and torque converter unlock points in the Custom Options menu. Or, maybe on an Edge you don't have these options. I have them on my Gryphon.

Like you, I thought the truck was downshifting too soon while towing. The Custom Options can correct this to an extent and Bill's tuning can do the rest.

I know on my edge that i can mess with the WOT shift points and the shift pressure. But i have never done this yet. Im so used to having a stick and giving up a few MPH to allow the engines torque to pull me through. The auto doesnt do this and so i find my self leaving it at %69-%70 so that i can force it not to shift. But i know i have more power and that if i would be allowed to raise it up to say %80 then it wouldn't lose any speed.

I don't think this has anything to do with WOT shift points. It has to do with 4-3 downshift, 3-2 downshift, etc. And, these are options on the Gryphon.

Like you, I'd rather be driving a stick shift. In a gasser, a little bit of "lugging" never seemed to hurt anything and I'd rather be there than downshift to a suddenly "too high" rev point - Unless I was passing, then, I want all the power I can get.

Maybe Bill can jump in here. We've talked about this before, but you've expressed the problem better than I did, I think.

I hope bill does jump in. I have heared nothing but great tings about him but have yet to talk to him.

I would have to look but i would take a bet that my edge doesn't have those settings.

Check the Model Number and Version Number on the sticker. If it's Model Number EEF2400 and Version E3.xx.xx then it's an older model that is not upgradeable and doesn't support torque converter adjustments or downshift adjustments. In those cases, Custom Tuning is the only solution to achieve the desired shift strategy.

The WOT Shifting adjustment won't do you any good except at wide open throttle. (In know, kooky huh? ) However, you should be able to raise the standard shifting to something a bit more suitable for your needs. The Evo should provide enough adjustment to give you a reasonable shift.

Hope this helps.
