Hey guys this is my first coyote to tune it's a 2016 auto 5.0 stang and so far it's going good car running fine except for the delay in down shift I hate it it take way to long....
I have looked threw tune but can't seem to find anything that would affect the down shift speed can any one point me in the right direction thanks in advance
This is a calibration from murfie I found in the repository. This tune has aggressive shifting. Do a compare with your tune. If you have questions, post your tune with your questions. Check out the repository when you need a comparison tune. Murfie also modded other parts of this tune as well. It would also help if you could share the mods on your car.

The car is stock besides mufflers I am at work right now can't post tune not much done to it beside adjusting the pedal sensitivity car had the delay in down shifting even bone stock no tune cruising nail the gas and there is a pause before it drops the gear it's annoying will post tune later today
And will check out that tune for comparison
here is the stock tune if any one can see what needs to be done to quicken the part throttle to wot down shift
Just make the shift happen faster? start with Reducing down shift Overall slip times by 33%... multiply them by .67. compare your RPM curve in chart v time of a stock down shift to modified down shift. You want it to look the same, no flaring of RPM, no plateaus, or drops after the next gear engages these indicate transmission wear. You are comparing the time taken from first RPM drop( on coming engagement) to RPM rise(off going release).

i am going to give a few things a change and try it out thanks for the advice will post up letting u know how it went
Murfie, i have a 2016 f150 5.0. What would you adjust to get the up shift to have less time for the actual 1-2 wot shift? It seems to take too long. Not very crisp. I can make it shift firm but there seems to be a delay in how quickly it can achive the 1-2 @ wot.
same thing with f150 6v shifts very slow 1 to 2
I dont know, but I think f150s had diffrant converters
The 2016 f150 5.0 has a ramp rate that falls off when torque for the 1>2 shift is high. start by increasing that Increase that.Originally Posted by kaineoutlaw

I also have a lot more info in this post.
