I am having an issue with my edge evolution which is installed on my 2007 F150 XLT 5.4L. I programmed it to level 2 (towing) and went to go test it out. Everything seemed to go well until I tried a WOT run. The RPMs just kept climbing until it redlined in 1st and never shifted to 2nd. I immediately backed off the throttle and gently drove it home bc I figured I have some sort of problem. (it drives just fine as long as I dont have the pedal to the floor) The only custom changes I made were tire size and speed limiter followed by variations of WOT shift points mentioned below).

After doing several hours of reading on this and other forums I have found contradicting statements that the shift points should be "at least" 400 rpms below the red line and other say it should be "no more" than 400 rpms below red line. I tried both with no success.

I am brand new to any of this programming so I am hoping it is just a stupid mistake on my part. Regardless, I have returned to the stock code where everything works correctly. If anyone can share some advice I would greatly appreciate it! Merry Christmas.

 

Can you please post up your values that you entered/changed?

 

did you change your shift points up, and when you did that did you set your rev limiter to the same amount? cause it won't shift that way....found out the hard way and thought mine was something serious. change your rev limit up a few 100 rpms and make a run and see if it shifts.

 

you should set the shift point no higher than 5250 for the first 2 shifta and no higher than 4800 for the 3rd shift. The max rpms must be 400 more than your highest shift point. So, if your highest shift point is 5350, set the max rpms at 5650.

 

Please allow me to be blunt.

If you don't know what you're doing, why would you risk destroying your transmission by playing around with shift points, TC lock-up, rev limiters, etc.?

Simply send the device to Power Hungry Performance, get it converted to a Gryphon, and get custom tunes.

A new tranny will cost alot more than the coversion and three tunes.

 

Thanks for all the responses/interest.

I changed the tire size to reflect the circumference of my 26.5/65-R17 tires. I changed the speed limiter to 110mph. My first run had 1-2 and 2-3 shift points at 5200rpm with rev limiter at 5600rpm. This didnt work so I tried 1-2 and 2-3 at 5200rpm and rev limiter at 5500rpm (to try the "at most" and "no more than" theories mentioned above).

Shotgunz: I appreciate the concern and sound advice. I am a mechanical engineer so I am not completely inept when it comes to this stuff, it is more an interest and I want to learn...otherwise, yes, I would absolutely send it in. Also, I am not looking for crazy power and whatnot because I am not racing people...this purely a learning experience.

 

You're welcome and good luck.

IIRC the TC starts to ballon at 5600 RPMs (someone correct me if I'm wrong), so be careful.

Here's a good read: https://www.f150online.com/forums/ch...shift-wot.html

 

Good point about the torque converter ballooning, I have seen several people reference that 5600rpm point now...I am going to try the standard settings for level 2 to make sure they work. If so, I think I will reduce my rev limiter to 5500 then change the shift points to 5100 for 1-2 and 2-3 and keep the 3-4 where it is at 4800rpm. The last thing I would want is my torque converter housing to yeild/fail. I will give that a try and post back. Thanks!

New question: WOT Fuel. In level 2 it is set to 1.3. I have done much reading and found that many people post it way higher (and one person who claimed edge recommends 1.6). I understand that this is the fuel provided to the engine at WOT, but how do I tell when the mixture becomes too rich? I have not messed with this setting yet, so if anyone has any insight, please let me know!

 

I'm going to add a small correction. According to Mike Troyer from several years ago, the TC starts to balloon at 5400 rpm.

A small amount of deformation at infrequent intervals isn't going to hurt anything though. As a mechanical engineer, you can appreciate the difference between "design limit" and "ultimate limit", and, as I understand it, 5400 is a "design limit".

Now, the difference between a WOT shift and Max RPM needs to be at least 400, and I've found it actually needs to be more for the 3-4 upshift, because it seems to me there is an "engine load" component in this upshift. Something Bill Cohron once said seems to verify this too, that the upshift is not ALL predicated on engine RPM. Possibly, for whatever reason, your upshifts need a bigger spread. Since engine HP and torque are starting to fall above 5000 RPM, I don't really see the need to have the upshift points much higher. I'd recommend you LOWER your 1-2 and 2-3 upshifts to 5000-5100 and move the 3-4 down to 4600-4700. I think it's fine to keep the rev limit at 5600 though.

WOT fuel is a bit of a puzzle to me. It's supposed to be a added amount (1.6 would be 60% as I understand things) that's available IF NEEDED above the normal fueling at a given RPM/throttle position. The engine rarely actually uses that much - as I understand it. I don't know that 1.6 is a particularly good figure though. Bill Cohron set mine lower (at 1.25 for the tow tune) and I've never seemed to need more. In fact, there have been a few posts where people got crappy performance by trying to add to the WOT fuel setting. I'd personally set it no higher than 1.3, which I think is Edge's "stock setting".

Hope all this makes just a little bit of sense.

JackandJanet: Thanks for the advice! Also, very good point about the WOT fuel. I was under the impression that the computer would force that fuel setting rather than utilize it more as a maximum benchmark (and this makes much more sense).

Unfortunately it snowed all day here so I will have to wait until tomorrow to work on the truck.

 

Jack: If Bill adjusted yours by 0.25 it may be 2.5 %?? Just guestimating out loud. I'd like to hear a better explanation from Bill, should the chance arise.

If you are making tuning modifications based on your sense of feel, smell or whatever there is little to be gained other than some misguided sense of accomplishment. Without proper data acquisition making changes is a crap shoot.....shift firmness may be an exception. A Pro tuner is familiar with your vehicles characteristics and knows where to optimize.

 

Good question (what I've bolded). But I think it's a "multiplier" from Ford's setting. So 1.0 would be bone stock and 1.25 would provide a 0.25 increase potential over bone stock. However, I'm just making WAGs here too and you're right, we need input from a tuner like Bill or Mike.

I agree that users should be able to make adjustments in shift firmness by "feel". But, as I've posted elsewhere, I think many overdo this and can be putting stress on the mechanical components of their transmission. One of our members, Longshot270, once said he didn't want the shift to fell like a kid was sitting in the back seat and kicking his seatback every time the transmission shifted. I think that is a very good analogy - when there is a "hard" kick, it means something is being put under a lot of stress.

There's a setting on the Edge/Gryphon though that I think is totally safe and that is the part throttle shift and torque converter lock/unlock points. Increasing them keeps the RPMs higher in part throttle giving more instant power, and reducing them gets you in a higher gear sooner, which might save a bit of gas. Since it's a part throttle setting, there's very little strain on anything and it does not effect WOT shifting. I don't know if you can change these settings in the other programmers.

Otherwise, ONELOWF, I totally agree with your post! You pay a tuner big bucks to make changes that will improve things and you alter those settings at your own risk. It seems kind of silly to do so.

Well this is starting to irritate me. I ran the canned level two and it DID shift at WOT but hesitated and was a very rough shift. So I tried again with 1-2 and 2-3 at 5025, and 3-4 at 4600. Rev limiter at 5500. I did not shift...(by this I mean I didnt give it a chance to, as soon as it was on its way past the shift point and to the rev limiter I let off the gas - this was all by watching the tach which could be inaccurate so maybe I shouldnt do that). Could this be my edge unit malfunctioning?

I bought this unit to keep an eye on temperatures and the tuning is just a bonus feature that I was hoping to learn how to use. But I do not like all this unsuccessful WOT testing I have been doing, its just not worth the risk. Any thoughts? And thanks so much for the interest and responses so far!

 

I'd recommend you contact Bill at PHP and get your Edge converted to a Gryphon with custom tunes.

I see shotgunz already suggested that!

 

glc: I briefly checked out their website. Do I have to pay for a whole new unit? Or is it just $30 for them to customize it?...if this is the case its almost just worth it for peace of mind. I have not done any research on this so please hold back the "do a search" rock throwing, but how do they tune my device without my truck? You said "send the device to Power Hungry Performance, get it converted to a Gryphon, and get custom tunes". I gues I should give them a call directly and they can help me out.

But one last time, does anyone think this could be a problem with my unit? Because I definitely dont want to spend money to get custom gryphon stuff if the unit is malfunctioning.

Thanks!
