i installed my egde on the other day and started messing with the custom tuned part right now its set with> 1-2 5500 with 18 shift firmness 2-3 5600 15 shift firmness. rev limiter at 6000. WOT fuel 1.71 and 1.25 timing advance so far its been pretty good best 0-60 is a 8.18 with 4.10 gear and 305/55/20

mods: banks exhaust and the tuner.

 

I'd really back off on those settings some. Try about 5000-5100 for the WOT 1-2 and 2-3 upshifts. Use around 4500-4600 for the 3-4 upshift and 5400-5500 for max RPM. Your HP and torque are BOTH dropping beyond 5000 RPM and your Torque Converter starts to balloon at about 5400 RPM.

I really wouldn't bump the shift firmness much above +12, +12 and +9 for the three shift points either. The "firmness" settings reduce the time between clutch release and clutch engagement. If you make it too quick, you put pretty severe strain on the drivetrain.

Unless you are burning higher octane gas than the tune is set up for, I'd leave the timing at 0. You may be getting detonation, even if you don't hear it.

And, I doubt you need 1.71 WOT fuel. You'd probably do just as well or better with 1.3 or 1.4.

okay thanks for you advice. i dont really understand the wot fuel. what is that?

and for timing advance, according to edge the extreme canned tune is set up for 91 octane and u can advance the timing all the way to 1.5 for 93 octane. so thats why i did 1.25

 

You only need to go +1.0 for the 93 oct.

For your WOT I would only go 1.5.

 

The +1.25 on timing is probably safe. That is what I ran on mine before I got custom tunes. Edge was pretty conservative, so I think it is safe. I ran the WOT Fuel at 1.5, this was per Edge's recommendation.

One thing to keep in mind, the 3-4 shift is the weakest point in these trannys, I would not go over 4800 rpms with that shift and I would keep the shift pressure on that one at about +9.

Plus, I agree with Jack in that you are pushing all of it a little too much for my comfort, and you get diminishing returns. I would try 5200 rpms shift points for 1-2 and 2-3, plus I would try a shift pressure of about +12.

You are correct in keeping the Max rpms at least 400 above your highest shift point. That is important.

 

thanks

 

No one really answered this part of your question, did they? Hear's what Bill Cohron at PHP told me: "The WOT multiplier controls how far the fuel adjustment can go in order to achieve desired AFR for peak torque. This is more of a limiter in the sense that it won't allow any fuel adjustment beyond a certain point. Outside of that, the main fuel tables are what offer final adjustment of open loop fuel while the MAF sensor provides the air mass values to the PCM so the PCM can have a base to maintain the target AFR of 14.64:1 in closed loop. Short and long term fuel trims take care of everything else."

So, WOT fuel is just an upper limit on fuel input in open loop - and you get peak torque at a lower A/F ratio than stoich.

The 1.5 advance in timing in the Edge manual is probably a typo. In another place they say to advance 0.5 degrees for each octane number. Since 93 -91 is 2, I'd think they meant to say advance by 1.0. I was worried you were burning 87 octane gas in an 87 octane tune and advancing the timing on that.

thank you for answering my question. i have another question though. what would happen if u put a aftermarket MAF sensor. would u raise or lower it?


Also i found this gas station by me that has 96 octane for sale, so i filled up with that today.

 

im a little confused and have a question as well. i have a 2004 (lean running) f150 with a cold air intake. people have told me i need a custom tune to fix the issue. but is it the WOT fuel adjustments that needs to be tuned? if it is, then cant i just customize the edge to fix my problem?

 

No, you cannot change the ratios in the program by changing settings. A new ratio table has to be installed in the programs.

 

ok thank you very much! im probably just going to go back to stock then and throw on the edge

 

No one answered this did they? Probably, because none of us has the slightest idea what to say. I'll hazard a guess, though. I don't think it would change the WOT multiplier at all.

If you have filled with 96 octane gas, you should be able to advance the spark 0.5 degrees for every octane number that gas is above your current tune. So, if you are running Level 3 (91 octane), you should be able to add 2.5 degrees to the timing.
