LMS 93 tune problems

[SHOBoat88]

I have been running the 93 LMS tune on my 2013 SHO for a good 3-4 months no problems at all. Car ran great til the weather started getting cold now it has a hesitation starting about 4500 rpms. I have re gapped the stock plugs to .030 that Didn't help. I called LMS they told me to switch to a different plug. Motorcraft sp528. gapped at .030. Still didn't fix it. I can put the stock tune back on it and it runs fine just feels like I am towing a boat. Anyone else had this problem with the 93 octane tune?

Any difference in the hesitation whether the car is cold or warmed up? When you reverted to stock tune, did you revert to the stock plugs as well? How cold of a weather are you talking about? Humidity?

This may or may not be related to similar problems being reported from the Louisiana area. Thought is that the DA may not be properly accounted for in the tune(s).

 

[SHOBoat88]

It does it with the car cold and warmed up. I have tried stock tune with the new plugs Runs fine. Its only in the 40s here now but thats pretty cold for us. Not sure on the da.

I just check drag times da calculator for my local track (Twin city, Monroe, la) I live about 20 minutes away. Today around lunch time it says it was -1200 da.

Do you have Torque or another such app running? Others have noticed significantly rich conditions occurring with tunes, and the possibility of being out of fuel has been mentioned. LMS should be aware of this, so I would contact them pronto.

 

[SHOBoat88]

I have talked Lms a few times about this problem. They are the ones to try the different plugs. He also told to try to run the 91 octane tune. I have the 91 tuned loaded up now. I have tried running torco with the 93 tune also. I dont have the torque app. I am gonna order a bluetooth obdii thing today. So I can actually see whats going on.

I've also started noticing this; there seems to be a bit of sluggishness in the mid-high RPM range. Has anyone else noticed any issues with the traction control being overly aggressive and hitting the rev-limiter instead of shifting from 1st to 2nd under hard acceleration?

 

[aaronjohnson]

Ryan, I've noticed this exact behavior as well. It does seem to not hit the rev limiter as much when traction control is turned off.

 

[ryanunderwood]

How are you turning off your traction control with the Non-PP? (Mine is, like yours, a 2013 non-PP)

I'm also having the same problem as stated above. Hesitation starting at 4500 rpm and on. Seems to only do it above 40 mph. Weird? I pulled my stock plugs and re-gapped to .030 did not help. Talked to LMS still waiting an answer, only thing I got from them was winter gas so far. Went from the 93v7 to 91v7 tune. It did not help. I'm running Shell 93 fuel. Oh my car is 2014 Non PP SHO with Airraid Filter, 170 Stat, and LMS 91 and 93 V7 tunes. They need to find a fix to this. I don't think its Winter gas.

I don't think it's winter gas either. I'm switched to the 91 tune (still running 93 gas) and there's zero difference in how it acts (maybe a tad slower, but same overall issues with sluggish spot(s) and rev limiter vs shifting)

 

[SHOBoat88]

Its not winter gas. I just took my tune off. I was scared to blow up my wifes car lol. I have tried everything they have told me to do. New plugs gapped at .030, 91 tune with 93 octane. I have even ran a bottle of torco and it was still doing it.

 

[ryanunderwood]

I haven't resorted to removing the tune yet. Whatever it is, it doesn't seem to think there's a problem (no codes or lights). I'm not a tuner so I don't know a huge amount about this but I understand this stuff to be lookup tables across a matrix of values and ranges, or at worst, linear algebra... whatever it's doing has to be because certain conditions are met.

Anyone know what I need to do to log this on my laptop?

Has anyone at LMS been able to recreate the problem? I can recreate it deterministically.

On another note, today driving home I experienced, for the first time, a long hesitation on a passing maneuver: I floored it from highway cruising speed in sport mode and it took a solid second to respond--like I hadn't pressed the throttle at all for about a second. Good thing I wasn't cutting anyone off.

Just to be clear: I do like my Taurus

 

[SHOdded]

Hopefully it is not an electronic throttle body problem that has cropped up on other late model Fords like the Edge and Fusion. Something to consider if you start seeing these hesitations under other conditions, can even cause stalling.

 

[SHOBoat88]

We like ours too. I was happy with the performance gains with the tune when it was running right. I did run a 12.84 tune only in decent weather. I called livernois today but I have to call back tomorrow and talk to another guy about it. I will keep yall updated.

Hadn't heard of that yet but will investigate more. I think I'll have to pull the tune to see if anything changes. I also really hope it doesn't feel too much slower...

I ran a 93 Livernois tune (4+) in my 2010 Flex from Naples to IA and back at Christmas a couple years ago (SCT Tuner version) and never had a bit of problems with cold or with fuel. Bought gas in NE Illinois and in ST Louis area where they often have different blends and not a bit of stall or hesitation. Vehicle felt no different than with my Torrie tunes.

The thing with LMS tunes is, you cant datalog them unless you have an SCT device. I dont know about you all, but I wont put in anyones tunes unless I'm able to datalog. I dont care who they are.

BTW, there is a tuner thats working on tunes for the SHO/Flex that will blow LMS tunes out of the water. He did it with the F150 and he's gonna do it with the SHO. These tunes are gonna have way more throttle reasponse, instant boost, and it will hold boost across the board. And he makes you datalog every tune to make sure it is working well with your vehicle, and to see if theres anymore left on the table. Something LMS does not do. These tunes will be true custom tunes. I will start a thread once he is ready to start selling tunes for the SHO. It should be after the 1st of the year.

Contact Brandon at LMS. [email protected] Ask for the CW tune.

Have seen his charm on another website and I wouldn't touch that kind of BS with a 10 foot pole. Foulest mouth I have ever seen in any postings... NO CLASS...
