[lemers]

A warrantied COMPLETE package is what I hoping for.

To all I am highly disgusted and someone upset at Ford and my dealership for each pointing fingers at each other on numerous counts. I however have different issues and mechanically my car has been very very good for whatever reason.

First off I have a personal friend that knows Ford's inside and out and tunes a lot of cars from Ford and FCA for each respectively. Their services are offered through their own brand. Since this cooler issue scares me a bit and my car has gone into limp mode twice with me at the wheel while in Chicago stop and go traffic it bothers me and NEVER on the track! Really weird scenario? My car also had Reduced Power mode and wrench on dash when I picked up my car 10 weeks ago for warranty work which is why I know someone at the dealership joy rides my car. My car has pretty much sat in the garage with no movement for over 9 weeks til last weekend to take it to super car saturdays near me. Ford and my dealer have been very stern about me taking my car out since we have been going over all the warranty work fiascos, fit and finish etc. They want little if NO mileage put on it and yet I do not have any resolution of any kind in sight or a hint. Just dumb? really not. Problems with the car so don't drive it and make it worse? Actually very smart. No car to drive, no problems? No resolution, no more cars getting used?

Reason I am writing in this category is I decided to take the car to the autobahn race track in Joliet, IL with my buddy who is a Roush employee. He brought his laptop to gather some info and see where the parameters are set on my car and he actually was able to go into the old saved eprom triggers and pull data on when my limp modes popped up. Everything is starting to make sense with these gt350's. Whomever programmed the PCM's did a crappy job and there is NO quality control on data control parameters. That is why you are not seeing ALL cars in tech and base package go into limp modes on the track all the time. I ran with 2 R's and a Roush RS3 and a couple of Vipers, a new vette and a camaro and other misc hardware.

Stock 2016 GT 5.0 with Performance Pack is set as the following:
Trans Temp is 250 at 30 seconds and 265 at 5 seconds
Coolant temp is set for 220 for 30 seconds and 240 for 5 seconds
Diff temp is set at 250 for 30 seconds and 265 for 5 seconds

Roush RS3 with 670+ hp kit is as follows for manual
Trans Temp is 245 at 30 seconds and 260 at 5 seconds
Coolant temp is set for 215 at 30 seconds and 230 for 5 seconds
Diff set at 240 at 30 seconds and 260 at 5 seconds

R parameter for reduced power is: Trans Temp threshold is
260 at 30 seconds and 280 at 5 then limp is applied
Coolant temp is set at 220 at 30 seconds and 240 at 5 then limp. You cannot see these temps. Only head temps which is approx 15 degrees lower.
Rear diff is set at 250 for 30 seconds and 265 for 5 then limp

Gt350 w Track Pack is very similar than R except coolant is set at 215 at 30 seconds and 240 at 5 seconds.

My Base set as Trans Temp at 260 at 30 seconds and 275 at 5 seconds
Coolant is set for 215 at 30 seconds and 240 at 5 seconds
Rear diff is 0. So no data input.

What is Tech, do not know had no car to read or judge against. We assume it is the same as the base but I was told it is probably less than that. Also I was told the decrease in ground clearance on the magnet ride can create less airflow under the car which creates another variable?
If any 2 of the 3 parameters come in at threshold 1 together you go into limp mode. So if car is running a bit hot on both trans and coolant. Car is in limp mode. If car is in extreme in 1 mode you go into limp mode.

That is the easiest way to put it in layman's terms.

So yesterday at the track the highest trans temp record on my car per eprom in PCM was 261 at 2.03 seconds at 13:14 military time and my coolant at that time was 226-228. So that is as high as I can get.

However a track pack car with 500ish miles race red hit limp mode!!!!!! Trans readings at 267-268 at 36 seconds at 13:33 military time and the coolant temp was at 239-240 for 16-18 seconds together. Limp mode
Diff was running at 237-239 for most of time
What made it do it? We checked parameter were set as what I posted per what I was given. My buddy Mark thinks the data is not accurate somewhere? Whether reading it through sensors or input of software to read data may have confused parameters. No way to reset or reflash.
Also track pack car was running track in gears 2-3 revving to 8200 all the time while I was running track in 3-4 and short shifting at about 7800. I still had a faster running as well.

Just some input. I am with everyone with a gt350 with ANY issue whether mechanical or fit and finish. Like I said my car is mechanically sound while fit is very iffy for now.

Hope this helps a bit.

I am trying to figure out a real tune that over rides the whole GT350 parmaters with custom add ins for other items. Lots a work for 1 car. Yes I looked at the thread on the OBD2 with for scan and thats where this data and testing was going for under true software that Ford runs.

We will see where it goes. I will show my support with you guys. I really think the dealers as a whole don't care and I really think Ford doesn't care because some of the items I have been told is utter ridiculousness especially last week from a ford rep "What do you expect it is a Ford" There will always be issues! This is not our high line car. If you wanted a better put together car I suggest you look at the Lincoln! This is our premium line. Imperfections are expected and considered fine on the Ford run of the mill lines including the Shelby and GT!!!!!! Look at the Lincoln.

Very upsetting and just ridiculous. I am with all of you!!! Give us what we paid for and what the Shelby moniker is known for! Performance!

Oh by the way my temp for coolant in what looked like both of my driving limp modes on highway were 273 and 276 respectively. Car basically overheating!!!

Dealer limp mode! Car revved attempt over 8000rpm with oil temp at 177 degrees. Threw limp mode

I guess good?

Good information thanks.

As my delicate little flower sits at the dealership with brass pouring out of the transmission I find myself reminiscing about the good ole days when I had the Boss. I could beat the crap out that thing and never had to worry about it. The Boss was bullet proof! I may trade my delicate little flower for something that will handle some abuse. I was planning on lots of mods but now I'm afraid something else will break as soon as I do. I Don't want a car I have to worry about all the time.[/





I'm back in a boss after owning a 350 tech......no regrets. I sold the 350 tech for $57K. The dealer that bought it has it for two months and now has it for $58K and still no buyers. Tech cars are dropping because of the 17 350 with all the coolers.

I don't have a transmission temp gauge.

Yes you do, read through the Forscan thread sticky in this forum.... If you have access to laptop w Bluetooth & Obdlink MX scanner, you can turn it on.

I too am waiting for a fix with a warranty. I have only hit limp once at a HPDE event but it sure seems to heat up in traffic. I can't monitor my trans temp yet but I can feel the heat coming from the tunnel in heavy traffic situations. On a side note, I am really enjoying my new Chevy 3500 HD. New Fords in my future? Only time will tell.

 

[VOODOO 6G]

Great info Crazyfish.

On a side note, I've bought 200k in new Fords this year. I would hope this means something to them. Hell I haven't owned anything but a Ford in years after terrible experiences with Chevy and Dodge. I really like my Fords and have yet to have an issue. I am disappointed that my GT350 is a lesser car than I thought I was buying. That being said I love the car and am going to keep it. If I need to I'll do a cooler mod myself while the car is put away for winter.

I don't spend lots on cars like you, but I feel similarly about how special the GT350 is. I will most likely keep mine as well, and do what I have to in order to keep the transmission and rear diff cool. I've been waiting hoping that Ford Performance's solution would keep the warranties completely intact. Too bad with making such a great car the last few details were missed. It doesn't change how much I love the car, but it changes my feelings about some other things.

This is a very detailed post and I thank you for that.

I'm not sure about the diff temps. I registered 315 on the cluster for diff at my last track event, a little bit in the red but it didn't limp. I pulled off as I didn't want to test if that were a thing. I just checked for DTCs but didn't have any temperature-related. :shrug:

Was it over the temps for the allotted time as well. It takes both the temp and the time to set it into limp.

It takes minutes to go from 265 to 315.

Really? I would have thought that could happen pretty quickly under track conditions. I'm also surprised that your car, with coolers would get that hot. I have no real reason to be, I guess I just am.

8. It sucks that my dream of driving this beast on the Autobahn and the Ring may be hindered by heat issues.

10. I believe my $57k investment gives me the right to be bitter about the heat situation.

Unfortunately, there is no "may be hindered," it will be hindered, as is mine...and yes, every right...

Ford...a symbol of America?:ford:

Well, it does have a cooler but it was just on this particular track conditions were right enough that the cooler couldn't keep up and the temperature kept climbing. That particular session it probably started from near 200 degrees anyway from prior sessions.
