2018 Mustang GT Redline - 7400 or 7500?

[ihc95]

There. 7500 confirmed. Now please close this God forsaken thread.

lol. Regardless......it’s not 7500, it’s 7400.

There’s a 7400rpm limit on the transmission

Thats a shift point. Not an engine limit.

And wheres the proof? You said there was proof of the engine limit but thats been proven to be onlypartially correct...

It’s not a shift point....and there are a lot of assumptions being made about the data Nuked posted. Read the whole thread, mate.

What assumptions? he posted data pulled from the oem tune. It clearly shows a limiter at 7500.

Id love to see the limiter on the trans file.

Again, you climbed a hill, and you're ready to die on it. But it's a shitty hill.

Why so angry bro?

Why so angry bro?

Im not. Im trying to digfig out how the trans acts as a red line. Especially on the six speeds...

That is the WOT shift points. I am not an auto guy, so not sure what the modes refer to. I would assume the different "modes" shown to the right, but I only see 17 not 19 as the chart references. I don't believe there is a "transmission rev limit", as you can see at WOT the shift point is pretty close to the rev limit as is. What happens if you manually use the paddles to hold a gear, does it hit a limiter?

As for the other screenshot, I can assure you that you will hit the Temp based cutoff before you hit the rev limit cutoff atleast while accelerating (not neutral). I learned this tuning my 16 and kept hitting a wall at 6850 even though I changed the rev limit to 8000. Once I changed the temp based to 8000 problem solved. Below is a 16 stock tune from my car. Notice that the difference between the rev limit and temp based is 150rpm, just like the 18. Stock 2018 is 7350, stock 15-17 is 6850 so yes Ford did raise it 500rpm.

See below.

Cheers Team Nuked, thanks for clarifying.

So, back to the question of whether the redline is 7400 or 7500rpm? You found the "hard" limit is 7350rpm. I suggest Ford selected a 7400rpm "redline" (clearly defined on the digital dash), and not 7350rpm as the increments on that display are in 100rpm steps. Hivel found his ECU had a Transmission Protection limit of 7400rpm so it gels that the redline is 7400.

My absolutely stock, including tune, 18 GTPP with 10 speed auto has reached 7530 rpm in 2nd gear in an autocross when I didn't manually shift in time. :-) A quick check of data files where I remember screwing up and hitting the limiter shows at least one more where it reached 7513 rpm.

OBD2 data recorded using a Race Technology DL1 data logger.

Momentum. Put the car in fifth and roll it down a steep hill with no throttle and you'll log 9500rpm. Redline is still 7400rpm.

If you hold it in gear, it smacks right into a rev limiter. I've done it a few times.

See below.

The difference being a hard limiter, 7500, and a situational limiter of 7350 based on temps.
An auto shifting at 7400 isn't a redline, its a shift point. In manual mode I have hit higher than 7400 rpm. The trans has no ability, when held in a certain gear to stop the engine from over revving, down shift a manual, see what happens.
And again, the manuals don't have said protection. Point is the redline is 7500 rpm. Period.

down shift a manual, see what happens.

That would be an interesting experiment, especially with rev matching... I don't plan on testing it with my Bullitt, but any other brave souls out there, for the good of the community........

I've downshifted from 6th to third in mine a couple times, about a 4k RPM difference, IIRC.
