Nope MGD... the "pop" I get when I am doing a 0-60 run is a second or two after take off... and the pop physicly is felt in the truck. That ain't no pinging!! The light pinging I hear is just all around driving at light throttle. I am not worried about that. Other than being anoying. But that pop is a lean condition at WOT. I have it set at level 2 with the WOT at 1.6 and no other custom changes.

 

My hex is RXCM4E8 05 FX4 5.4 New Edge with newer plug.

The only problem I seem to be having is that my tire size custom setting does not stick. It reverts back to 2356 no matter what I put in. I checked the speed with GPS and its off by the right amount on both the speedo and Edge. I have 35s and am trying to set 2792mm.

I just downloaded the latest "stable" and no change... so I downloaded the "UNSTABLE" firmware and beta calibrations... no change..

As I said, truck seems to run fine, but I can't change tire size. For the hell of it, I also tried to change the speed limit to 200 and that didn't stick either. I didn't want to mess with any other custom settings.

Any help yould be appreciated before I call Edge on Monday.

Thanks!

 

Ok Chris - BTW, why are you not concerned with light-throttle pinging? Just curious, is all. I know I would be, as I have never had that issue.

The KS system has got to be affecting power when that occurs....

Good luck.

 

nah.. lite throttle pinging is ok. It just means it has the max timing advance. that won't hurt anything. The WOT pop keeps me from ragging on the rig. Not that I need to. but still a concern. Back in the day... the 1970's... a ford mech I new would advance timing to slightly ping on full throttle accel.. and never had a return.. not that it was a good practice. but there were no blown engines from it. and he got the best fuel milage and power that way. I think the knock sensor is doing it's job if it pings slightly on normal accel.

 

i have that shudder at that same speed60 -65 or so. im on level 3 but de-tuned a little bit for better gas mileage.
the other is a "muffled hum" coming from the engine bay at highway speed. not a vibration, nothing that sounds like damage, but just a really low toned mmmmmmmm. just getting ready to get to the bottom of it, so if this forum can save the middleman of going through edge, then lets do it.

 

pKai,

That is pretty stinkin' wierd. Let me ask... are you certain that the values are not sticking because they revert when you go into the custom options? If so, are you selecting the "Reload Custom Options" on the Options menu before you go back into the Tire Size, Gear Ratio or Speed Limit options? If not, they will show the default stock values form the PCM not the values you had previously selected.

Also, when you set Tire Size you MUST set the Gear Ratio. There are instances where the default value in the PCM may be different than what the vehicle actually uses.

Finally, while 35" tires do in fact come out to 2792 mm, I have found that you have to account for some tire squish to improve the accuracy. Ford's diagnostic equipment actually accounts for roughly a 7% squish while I have found that 5% seems to work really well, especially with an All Terrain type tire. This would yield a value of 2652 mm.

Give those a shot and let me know if that works any better. Good Luck.

Chris,

I don't recall reading *ANYWHERE* that a little light pinging is okay. Pinging is pinging and it is not good.

Let's put it this way (and really, I'm not trying to be a wise-apple...)

I hit you once in the head with a 36 oz sledge hammer, you're done.
I hit you thousands of times with a 2 oz hobby or jewelers hammer, it'll take longer but eventually you're still done.

It may take weeks, months or even years but every time you hear detonation there is something bad happening to your engine and eventually you will have a problem, most like in the form of reduced service life of the engine. I highly recommend you engage one of the following options...

• Increase you fuel octane, either buy buying better gas or using an octane booster.
• Changing to a lower performance setting.
• Reduce the timing using the custom options.

As for your pop at full throttle, I am quite interested as to what that is. That's the first I have heard of it (as far as I can recall) and would like to get more detail as to the specifics of it. Any information (RPM, Engine Temp, Air Temp, Power Levels, Tuning Options, etc.) would be appreciated. As always, include you HEX code in any posts as it may be specifically related to particular calibration family.

Take care.

Bill

 

ok... the pop is when I go 0-60 full throttle. It is over 4000 rpm when it does it. air temp around 50-60 deg. engine temp 194 power level 2 with only custom tuning WOT at 1.6

my HEX is RXDG4B2.HEX
Boot loader V1.00b
product E3.22.27
firmware 22
2007 screw with the 5.4, 3.73 gears, 17,000 miles on the truck.
magnaflow SIDO exhaust.


I use shell 87 oct. gas exclusivly from the same busy station every time. I have no other issues that I recognize. I don't have any tranny shudder, or non start issues. Truck runs great and get between 17-18 mpg mixed driving. But then I try to maximize milage by using speed control and energy management.. like using hills to my advantage and keeping the speed up.

I would think the computer would use the KS system to keep the timing in check. So I don't understand why it pings.

thanks for the help.. great to have people like you on the board.

 

It's about time you chimed in on this one, Bill.

Chris wasn't about to listen to me !

lol i listen to all.. The pinging I am talking about isn't the rattle I think you mean. In all my years, I haven't seen a problem with very light pinging. No where near the heavy rattle. Guess you would have to hear it.

 

i have read this thread, i downloaded the update and its in my computer and now im reading the instructions that came with my edge. i am still not clear on what to do next.

could someone give me step by step instructions on what to do next? thanks guys in advance!!!!!!

 

ASEmechanic:

It seems like I was not "reloading previous" excatly like you said. Another check with GPS made the lightbulb come on.... Actual speed was SLOWER by about 6% than what the speedo read.. which is in the wrong direction for having just put on bigger tires, but it IS explained by the "squish factor" which I did not set initially. I then set the size to 2652 as you suggested VS the 2792 the manual calls for and its dead on...

Now my question is -- although I'm not having any problems that I can see so far (after a day)..... should I drop back to the latest "RELEASED" versions of the Edge firmware and calibrations or keep the "UNSTABLE" and "BETA" version I already have? Does the "RELEASED" versions exhibit any of the issues previously described here for my year truck/hex version?

I want something stable that will work on my truck -- I do not feel like experimenting with less-than-well-tested software.

Thanks a million!!!!

 

One more question -- In the lightning software, there is an "Advanced Features" selection in the menu. It asks for a key when I select it....

1. What is it and what can I do with it?
2. How does one get the key

Thanks!

 

It allows you to extract binary files that contain the tunes, among other things, and you need an Edge rep to give you the key.

 

pKai,

When Edge posts updates, they will use the term "BETA" or "UNSTABLE" to indicate that there has been a change to either the firmware or calibration files. This does not mean that they aren't perfectly usable programs. They are not trimmed down or hacked up versions of what would be considered a "RELEASE" version. They simply have a minor change applied and the rest of the file is unchanged. If the the file is working fine, then don't worry about it. Going back to the a stable "RELEASE" version could reintroduce a problem that was resolved in the update. After 30 days, if there are no further issues, the status will change to "RELEASE".

As for the Advanced Features, those are diagnostic features included to help the Tech Support guys download specific files from your unit in order to help troubleshoot any programming or drivability issues. There really aren't any useful functions.

Take care.

Bill
