Just wondering what your rpm's are both stock and in tuned mode at 70 mph (highway speeds) right now my truck at 70 mph runs at 1800 rpm's, just wondering if the Edge Evo would lower the rpm's at 70 mph.
Thanks for any of your expert inputs...

 

No they don't change. The only way you'll see a change in RPM's is through different gearing of your transmission and/or differential.

 

...or by entering the wrong tire size or gear ratio in the Edge program?

 

I never checked my rpms before I started running the Edge, but mine is 75 mph aat 2000 rpms.

 

no. that will change the speedometer not rpms. only way to change rpms is by gearing or tire size

 

I wasn't sure if by some form of electronic magic it could/would lower the rpm's at hwy speeds.

 

If I'm not mistaken 1800rpm at 75 is really good!!!
lower RPM equals good gas milage.

as far as altering the rpm, I'm almost positive theres only two methods that will alter the RPM's:
1.) RPM's at idle
2.) and what RPM's your transmission shifts at?
This could affect highway speeds and RPM's.... ???RIGHT???
Correct me if I'm wrong!

 

What I meant was that if the gearing or tire size are not entered correctly in the program that the rpms would "look" to be different at any speed. Of course, the real issue would be that the speed readout (speedometer) would be incorrect. I was trying to indicate that if bshipley78 was seeing a change in the rpm/speed relationship with the Edge, that he might have the wrong gear ratio or tire size programmed?

 

You are mistaken, he said 1800rpms at 70mph and the other one was 2000rpms at 75mph

 

ooops your right!
1800rpm's @ 70mph
and
2000rpm's @ 75mph
ideally thats still respectable RPMs vs MPH resulting in excellent gas milage..

 

At 70 mph i am at 1800 rpms and at 75 I am at 2000 rpms but on the hwy I only get like 13 mpg, I am looking into buying the edge evo, i haven't gotten one yet. I was just wondering like I had said before, that if by some form of electronic magic it could lower the rpms at hwy speeds. I am trying to improve the fuel eco for my truck. I know it is a truck and that she's built for towing power but with todays technology you would think the fuel eco would be a little better. I may look into replacing the gears, I originally bought my truck with the intent of buying a travel trailer for camping, so I thought I would need the extra umph when towing but the trailer plans have been thrown out the window.
Thanks again you guys, for all of your input's

 

most of the tuners/programmers available will allow for better gas milage and better performance!
thats if you can resist laying into the throttle with the newly added throttle response and power!

 

There is no way a tuner can change the rpm at a given speed. This is a mechanical function. When your torque converter is locked, the gear ratio of the tranny and the axle determine the rpm at any given speed. The only way to lower your rpm at 70 mph is to go to a lower ratio gear set, or get larger diameter tires. It is not always true that lower rpms give you better milage either. some engines have more efficiancy at relitively higher rpms and give better fuel milage.

 

^^^also very true. your engine may need to work harder to keep the truck moving at lower RPMs

 

Thanks for explaining on a level I can understand!
I didn't dispute the mechanical function of RPM vs MPH!
I was stating the functions available via the programmer/tuner.
