LMS car with trans issues while still cold

I have a 2013 PP with a LMS 93 tune. It's been pretty cold in NJ lately and I've had an issue with my trans at WOT when the trans is still cold. Besides the hesitation in 3rd gear, last night it felt like I was in my 5.0 and missed a gear. I had to take my foot out of it but it seemed ok after it warmed up. I talked to another(NJ resident also) LMS customer earlier and he's having the same issue. He went back to the stock tune and he said it's fine without the tune. Any thoughts or ideas???
 
Email Brandon at LMS.  blowe@livernoismotorsports.com and ask for the CW-Cold Weather tune.  It is supposed to take care of many of the problems that 13-14 SHO and XSport owners encountered when the weather changed. 
 
One possibility is fuel octane. From what I understand if there is knock being sensed the car will automatically retard itself creating hesitation or miss type issues. Might try 91 tune and see what happens. Just because a gas pump says something it might not be so.

 
I would not recommend going WOT on any car that is not up to operating temperature...?

I've run my 93 Unleashed in everything from 100 degrees down to 18 degrees and it runs perfect every time.  Call your tuner.

Completely agree.

The concept of pressing a car, particularly in colder temps, when operating temps haven't been achieved & fluids flowing properly is beyond me.

I too have had ZERO issues from having operated my SHO in either end of temperature extremes.

Whether that be well into the triple digits, or below zero temps.

Since I am running an LMS tune, just as the OP reports to, the advice of contacting your tuner, is sound.

Just sent Brandon an email.

Guys, I realize WOT when the car is cold is probably not the best idea but if it doesn't happen with the stock tune then it shouldn't happen with the LMS tune. I'm also getting a hesitation at times when I hit 3rd gear so something is up here. We'll see what Brandon says.

Thanks guys
 
I'm in NJ and the other day when the temps were in the 50's, I decided to switch into "sand" mode.
I have the 14 XSport with LMS 93 high boost.
Truck was plenty warmed up as it was running and driving for at least 40 minutes.
I switched to sand at light and went WOT, as I heard people talking about being stronger in sand mode...

For the first two gears(I think only 2) it did feel a lot stronger..... BUT....

Then it abruptly went into neutral and just started revving out....
I immediately let off the gas and pushed it into neutral and then back into drive....

I was shocked and worried....but I had no engine light, no other symptoms of issues or sounds...

I have since not went WOT from a stop but have got on it strong while moving and have had no issues what so ever....

I'm still concerned....
Anyone have this happen before or have any idea what this was and what caused it...


I haven't had any cold weather issues with my tune so I did not request the cold weather tune..

Thx
 
That happened to me once on the 1/4.  Except it was at the top of 1st.  I'm pretty sure it was the "granny" kicking in.  Never happened again.
 
How do you guys monitor trans temp? or do you just mean the coolant temp? I wouldnt ever floor it when its cold I have to cold start my car everyday. we have tempatures as low as -45 with windchill for a few days at a time. the car always started well I always gave it ample time to get the coolant heated up atleast past the first marker on the gauge.
 
Transmissions generally warm up slower than the engine.  Maybe twice the amount of time (or more in colder weather).  So yeah, it would be valuable to monitor transmission temp.

So incredibly true!

I see it all the time on my tranny temp gauge.

Consistently twice as long to warm up as the engine.

Mine did the same when i tried using that mode. I have not used it since. Most people say they get the best 1/4 times running in normal/manual mode anyway.
I've also had it kick out of gear once when i got into it pretty hard and the road got bumpy. It kicked out of second and did a free rev on me. I let off and it was fine after that.
 
As others have stated multiple times, not being fully warmed a big no no. Also I have read that are cars will hold gears longer when cold, also 6th is not available until trans reach operating temperature.

On another note about tunes there seems to be a lot complaints about them. More and people seem to get them expect there car to perform like it did stock, except better. As we all do, but to me at least it like comparing apples to oranges stock vs tuned. Why car behaves this way tuned and don't do that stock under same circumstances.

Now I am not trying to be critical of anyone, as a early adopter of tune myself and with other adopters, we had are own thoughts and ideas about early tunes of refinements to them.

But never did seem like complaints, I loved each and everyone of my tunes even more than last one, as there has much improvement from the 1st to the last one.

I guess what I am saying is work with your tuners provide them with feed back of improvements or bugs you having or would like to see, and be patient.

But if your dissatisfied and feel your complaints need to be aired, maybe tuning isn't for you.

Again I am not trying to be critical of of anyone, and we all have high expectations of anything we purchase. But they should be realistic expectations, I'm mean heck when my car is cold if I get in it to hard it will sputter. Mentioned to Dan the tuner at LMS at the track one day, not even sure why or what we where discussing. But he said "yeah I did that." So not damage engine not being fully warmed.

So what we see as bug, may have purposeful use. Not saying all bugs are purposeful. But make your issues purposefully well placed.

So if someone has a problem keep it between them and the tuner only?
I disagree 100% A tune is no different than any performance upgrade and everyone wants details about a mod.
If mod A performs great and nets more power than mod B people want to know.
If sharing an experience with ANY mod is frowned upon then maybe the internet is not for that person.
Regardless of an issue with any product, tunes included people can and should share with others if they wish to do so.
Knowledge is key and if people don't share it the aftermarket world would suffer.
 
Well maybe point isn't coming across clearly, I don't disagree with you. Was my take upon the many gripes I have read lately and some of them I feel there expectations of there tunes are out of touch. No offense to OP but his gripe is his car hold 3rd @ WOT when cold.
Again no offense to the OP and truly with heart mean that. Maybe he just don't know what he should or shouldn't expect, as I've had fellas over there years on these forums admit to me they don't know how to even change a tire.
And thats ok, and thats what great about modern day tech that you don't have to know anything about working cars to make your car faster.
But we need to have reasonable expectations of how are tunes perform, as ford motor has probably spent 10 of thousands of hours developing the factory tunes for ours cars in all types of climates and conditions. VS a tuner that probably only has a few hundred hours under his belt.
I am not trying to silence anyone, as communication is the answer to everyones issue or desires. And again we all have high expectations as do I as I believe there is plenty more potential in my car in its current configuration. But my take on tuning its not one a one and done deal. Its a on going process, and many factors at play as each car is sorta of unique base location elevation and climate and fuel type availability.
I all was trying to is shed some light on having reasonable expectations, and working with your tuner to resolve issues. As not everyone is effected but some are and they have to figure out what it is and what to do fix. And this usually means dyno time, and track time. To reproduce and figure how to correct.
Its no different then going out and buying the latest version of Windows, to find out it has bugs in it too. And I am sure MS does everything possible they reasonably can with quality control to test, and yet once it hits the masses they all surface.
Heck with assumable 10 of thousands of hours of Fords factory tune isn't without its flaws.
 
I understand what you're saying, i took the OP as asking if others had the same issue more than a gripe. Of course reading more into the thread it seems to have turned to that.
There is a cold weather tune though that LMS has released to address some issues, perhaps it also clears up the hanging up in 3rd issue, i'm not certain on that one though.

Does this 'cold weather tune' apply to 2010 SHO's?  I'm very close to getting a tune from LMS and I live in Chicago, so I'm wondering if this applies to me.
