I plan on doing the same. Thinking about the OZ Omega tune, just for the flexibility. Though I use 87 octane 90% of the time.

But I also plan on swapping a 5.0L Coyote and 6spd manual into my old truck to have fun with.

Great "take" sixshooter. You said "automatic rev match". This is as good a time as any to bring this up . . .

Is it "safe" to use the shift button on the console? I've always thought it was bad to downshift automatics. Upshift, NP. Hold in a gear, NP. Nowadays, many cars have paddle shifters. I assume the function is there to be used. I mean, there's no warning in the manual. My service manager was like "duh, well keep it under 4k", but I think he had no idea. So what's the skinny? How can we get a Ford Rep in on this?

I've been downshifting mine, but try to keep it under 2500.

I'm just sitting here waiting for someone to come out with tunes for the 2017 3.5EB and 10 speed.....anyone? lol

SixShooter14

It's only been out for what 6 months? That's only 400,000-ish vehicles. You can't expect tunes already LMAO

typically if it isn't safe to shift, the computer won't let it. Much like putting it in "M-mode" in 6th and coming to a stop. It will downshift on it's own.

4k rpm? If I wanted to stay under 4k rpm, I drive a tractor.

Oh and about paddle shifters... YUCK, I hate them. Just my opinion.

I talked with 5-Star yesterday. They are working on their "Clunkmaster" 2017 F150 and have about 80% improvement in the clunking. I suspect it will still be a while before it's available in a downloadable handheld from what I was told.

They have some dyno charts for the 17 3.5EB w10spd on their website.

Regarding shifting an automatic:


"
Dual-Clutch Performance
The proliferation of dual-clutch “automated manual” transmissions give you another reason to learn how to downshift. These gearboxes feature a pair of internal clutches instead of a traditional torque converter automatic, which allows them to pre-select the next gear and offer lightning-quick changes at speed. Downshifting one of these transmissions — usually with a steering wheel-mounted paddle — is very similar to using a standard manual transmission, only without a clutch pedal, and often with automatic throttle-blipping to smooth everything out. Think of it as a high-performance manual box that will also shift itself when you don’t want to get involved, like when you’re sitting in rush hour traffic.
Downshifting an automatic transmission can be a practical skill, if you also learn when and where to use it. Low-traction situations, towing or just having fun in a dual-clutch sports car are all scenarios where you might want to manually intervene in the shifting process, giving you more control over power delivery and letting you get that much more involved in the task at hand.

Interesting stuff. At least there's a reason. I don't know what we have under the hood.

It's not a dual clutch trans.

That's exactly how "sport" mode is supposed to work.

That's true, but the wiki description is pretty bad. It is more efficient at heavy loads, but also using more total fuel. Remember, efficiency is power made/fuel used, so high power will still use more fuel even if the efficiency is high. "Lugging" the engine *is* putting it under a heavy load (high efficiency) but also keeping the power down (less fuel).
