Hello,

I have not been on this site for a really long time and am looking for your help on how to set the shifts point for my Superchips 1714 tuner.

I have a 2004 F-150 4.6L and have it programmed for 91 octane.

How would I change the shift points?
Do I need to change the shifts points?

Please let me know.

Thanks

Chris

 

Hi & welcome.

While waiting for MT, check out these threads discussing shift points.... all of this has been covered before , so it's easy to pull up stuff like this at any time using the Search feature...

General consensus is, leave them @ the Superchips default settings unless otherwise noted....

Hope this helps.

Thanks,

I read through a few threads and people state to change just the 2-3 shifts to +2. Has anyone done that and notices a difference.

I would like to acheive the best performance for the 4.6L because as you already know there is a lag in response.

let me know if i should change any other shift points?

Hi Chris,

Here's the deal:

What you want is for the full-throttle 1-2 upshift point to hit at about 5400 rpm, and the 2-3 full-throttle upshift point to hit at about 5300 rpm. (Don't worry about the 3-4)

Now that is usually about 200 rpm above where Superchips sets the 1-2, and about 100 rpm higher than they set the 2-3 in that tuner, for that vehicle.

Just remember the numbers in my first sentence, and you'll be fine for your performance tunes.

Now for towing-compatible tunes, you do not want the full-throttle 1-2 or 2-3 to be any higher than 5200 rpm.

And on the off chance that you bought a truck without a factory tech, invest in an aftermarket tach so you will know your rpms, OK?

Now for those using the Superchips *1715* tuner in the *1997-2003* trucks with either V8 engine, just bump the 2-3 shift point up 2 "notches" and leave everything else alone, and you'll be set for those vehicles.

Thanks for your post & good luck!!

 

Thanks Mike T,

Your information is very informative and helpful. And it also makes sense.

Sorry to keep asking questions, but when i have the truck set to performance tune, when im in 4th gear and want to accelerate a little bit to pass a big rig, the truck downshifts to quick.

Is this normal? I barely touch the gas pedal and it is downshifting. WTH....

 

Well, that is a matter of two very simple things - the throttle position and the vehicle speed - that is what determines your part-throttle upshift & downshifts points, is the throttle position you are at and how fast the vehicle is going.

You need to remember that even when cruising at 70 mph in Overdrive, you are still only turning barely 2000 rpm, and on part-throttle at that low an rpm the motor just isn't making serious power, thus it has to downshift (well, first it will unlock the torque converter, and then if it needs to, actually shift back down into 3rd or 2nd) pretty quick when you command additional power, which is as it should be - the vehicle is going to do what it needs based on how it is calibrated to try to respond to driver demand.

Now this *can* be improved, but it has to be done via our Troyer Performance *custom* tuning. We add easily double the power that the 1714 unit does with our custom tunes (and they come in a different tuner), and we also have a much better transmission shift schedule, as well as a better torque converter lock/unlock schedule - but that is because we specialize in these trucks, whereas the major chipmakers do not, they put out applications for hundreds of different vehicles - so while they do improve performance, they simply don't have the amount of R&D into these trucks that we do, that's all, and that is to be expected. the 1714 is fine for what it does, but to get better tuning, if that is desired, that's when it's time for our custom tuning.

Anyway, that's the scoop on your downshifting, is your throttle position and vehicle speed, along with the fact that the engine cannot make much power at low rpms on part-throttle - between that and the sheer weight of the vehicle, that dictates your results with the tuning you have.

I hope that info helps, & have fun!
