I have an 07 f150 with 35" tires, 40 series flowmaster true duals. I wana know what settings I should put my edge evolution on to get better gas mileage n performance. Heck I dnt even know what to put on tire size

depending on what brand your tire is the exact number will vary for example my trail grapplers are 34.8" not exactly 35" so I calculated it out to 2780mm i believe. Make sure you change your gear ratio to correspond with your rear end. I run premium Texaco in my truck so I have my timing bumped up 2 degrees that will help your gas milleage. Be careful with timing though if you get pinging you need to lower it down some or you will damage your engine (when i filled up with premium at the RaceTrac gas station I got pinging so I went down to 1.5 degrees) use the display the instant mpg it will help you to drive better its not an exact number but you'll see when you're being a little heavy on the gas

Ok thanks n they are mudgrapplers. N how do I make the gears go with my rearend?

same thing i need to no how to ajust gear for tire size

schissler

adjusting the gear/tire size is only to correct your speedometer.

if you have stock gears you either have 355 or 373 and thatll probably be set in the programmer already


dont even touch your timing. "pinging" is detonation aka pre ignition. your basically taking hammer to your piston and bearings when this happens.

Adjusting the tire size and gears also helps your transmission

My speedometer is bad off. But Idk what gears to put in w/my 35 mudgrapplers

schissler

yeah...when you PHYSICALLY change them in the differential.

the settings on the edge will do nothing but adjust your speedometer.

only thing they do to your transmission is change the shift points because they will be off a tad.

What size should I put in for tire,size n gear? N shifting points?

I also had a question about the settings. When my truck shifts from 1-2 it shifts hard but not in any other gears. Is there any shifts points or conv lock/unlock or anything I can do to help this
