Limp Mode on the Track

[EF300]

Not a chance

^ RE the possibility of a class action sutie if they dont address the problem

That is a bold statement. In America people sue over coffee being to hot. You thing someone wouldn't sue ford over a 60K car the overheats on the track ? I bet they would.

So far, I haven't seen a credible analysis of the problem - just a bunch of guessing. At this point, no one really knows if it's a problem. Maybe it's a sensor or wiring problems on the early cars. Maybe it's drivers who use the transmission to brake. Maybe it's the bean counters and market research people at Ford who guessed wrong on how buyers would view (and ultimately use) the Tech Package, which accounts for more than 60% of the build so far.

Dude, I don't know what more you want. It's just coincidence that at precisely the same transmission temperature power gets cut? Really? I repeated this at least 6 times. There's no doubt in my mind. I guess it's a good thing you don't trust everything on the internet but at some point, you're just being skeptical for the sake of it.

Don't confuse my skepticism with not believing there may be a real issue here. Look what happened with the paint boogers and transportation damage issues - a few reports, and then a whole bunch of photos proved these are significant issues. That got Ford's attention.

A car (or two or three cars) with an unidentified limping problem does not create a trend. You've reported a repeatable symptom that I have no doubt exists in your car, but I want to know the source of the problem. Is it the lack of coolers, a short in the wiring harness, a run of faulty sensors from a supplier, driving style or just people being pissed because their cars don't meet their expectations? Before everyone goes nuts, Ford should have an opportunity to look into the problem. :doh:

Matt I think your analysis is pretty spot on. On my car the digital tranny temp gauge turns red 300F so having the power cut come in at 280 seems right in line with what Ford deems dangerous.

Hopefully more folks will get the ngauge and do their own logs. Hopefully a track pack owner can help out as well with logging their temps at the track

How can two 1500 degree infernos not heat the transmission?

Which one are you using to slow down? The brakes or the transmission? Sounds like a driver flaw to me.

When I referred to the transmission I was referring to transferring power, which is what a transmission is designed to do. I was not referring to slowing down. Sounds like a reader flaw to me.

Yes it will be fine. Sustained road course track use is an entirely different beast - that's where the Tech pack is having some difficulty. If you want to hit some tracks retrofit some extra cooling like the Track Pack and it will be solved.

I'm worried about the "sustained high speeds" line in the manual. What is considered "sustained high speeds"? With that verbiage ford can claim any limp mode on lack of track pack.

Spot on comment! I've had GTIs, Golf Rs, S4s and the CLA 45 AMG I just sold to get the GT350 do 20 minute sessions no problem. If the Mustang GT PP, or any other newer Mustang for that matter can do a 20 minute session and not have the transmission overheat, then it's definitely a design flaw.

Us Tech guys are not talking 24hr Le Mans sessions, is 20 mins too much to ask for?

Thanks, I feel that ford owes us an improvement over the GT with PP. and should be looking for a solution.

I understand now. I read good. ;) You did say stopping...and transferring that power.. Seemed like you were referring to decelerating.

I'm just speculating here, but since the engine limits to 5k RPM once the transmission heats to 280F, then it's fair to say it'd have a hard time with whatever speed you're at in excess of 5k+ RPM. I don't have the gear ratio chart handy, but that'd be mighty fast. You'd be getting a bunch of extra cooling from the air going that fast as well, so :shrug:

Well until July 2018 I'll be driving on the autobahn. So, it may be possible since I'll be driving plenty fast.

Finally we got Jeff to agree with us !

Would be really cool if the Track Key could help to make a difference here, presuming that Ford is going to make that option a reality and if it is a sensor issue (or something like a sensor issue) I think it would be awesome for Ford to integrate a fix in the Track Key.

My guess is that it's not a sensor issue and it is an actual cooling issue, in which case I hope Ford provides a "Ford Approved" fix for track guys. I will likely never make it to the track, but I certainly want the option to.

 

[Katastrophe]

I'm pretty sure they already know about the issue as that's probably why they're
offerering the coolers as standard equipment on the '17.

Why else would they offer coolers on tech cars, just to bump the base price. :shrug:
Just doesn't add up to me.

We're actually waiting on member SVTDSM to check back with us what he found out with talking to Mike from FP.

That is what really got my attention with this...MY17 standard equipment. I mean, it makes sense to revise the packaging for 2017...it works for everyone now. You can finally get any (nearly) option(s) combination you want...

I'm sure we can all guess on why FP would do this...but it would nice to hear it from the "horse's mouth"...

So what are you planning to do with your car? Is it possible for you to get into a MY17? Or are you just going to go aftermarket for possible cooling solutions, etc?

I can see this being an issue for even the track pack in the summer. Just did Barber this weekend (has a few decent straights, but not a super high speed track - mostly 3rd gear). OAT was 60F and engine oil topped 250 as well as the rear diff. So if OAT was 90F you'd be bumping that 280 mark on both. Trans never got that hot though.
