Another happy LMS tuned SHO owner

MTaurusSHO · January 17, 2014, 12:40:29 PM

I installed the 91CW tune last night, all I can say is wow! I can't believe how conservative Ford decided to leave these cars.

I have some questions, I still need to install the colder spark plugs and thermostat. Is there a write up somewhere? I've searched but I can't seem to find one. Or if someone could give me some tips, I wanted to start an this today.

Glad you are happy with the tune! There is a brief write up on plugs somewhere. Just in the last month. It's buried in a thread. The T Stat should be easy. Take out the stock intake box or whatever you have and it's right there.

Are any fluids lost during the T-stat change? Are the plugs pregapped from LMS ?

DJE624 · January 17, 2014, 01:22:40 PM

Guys have reported losing minimal amounts of fluid up to maybe a cup. The opening is kind of tilted so you can catch most of it. I don't know if LMS pre gaps the plugs but you could ask them to, I guess. They do recommend .30

Glad you like the tune! congrats!

Here's a couple of threads on the spark plugs
http://www.ecoboostperformanceforum.com/index.php?topic=1404.msg24191#msg24191 (long but a lot of good info)
http://www.ecoboostperformanceforum.com/index.php?topic=1651.msg20729#msg20729 (short and to the point... but limited info)

A few for the T-Stat:

There are snippets in other threads... search from the forum page for best results.

Ecoboost performance parts can get the T-Stat at as good a price as i've seen for a good one:

You really want to change the T-Stat and plugs as soon as you can. I'ts more than performance, but important to prevent knock (predetonation) beyond what the ECM can adjust for with the tune's modified timing... potentially could cause serious engine damage.

Hope this helps! Rock On!!!!

Per Dan at LMS.... LMS uses an expensive and sophisticated tool to gap the plugs..... the standard autoparts house feeler guage doesn't really duplicate it or give the consistency. However there are other brands and you likely can beat the price.

I wasn't aware of this. I don't think LMS tunes beyond what the ECU can handle. I will however be doing these upgrades, 170 T Stat and one step cooler plugs, to prevent detonation and lower the heat sink in the engine compartment for over all better performance.

A lot of the 2013's have the colder plugs installed from the factory, they are the same ones Ford uses for the F150 Ecoboost. All you have to do is regap them which is what I did. Now I have a spare set of plugs because I bought a set before I pulled any only to find out mine already had the colder plugs installed. The gaps were all around .038 on the stock plugs but I only had just over 200 miles on the car when I went to change them.

MTaurusSHO · January 17, 2014, 01:51:26 PM

Thanks guys, I'll get started today.

Here's what knock can do... These are from a Ford TSB on aftermarket tunes

What are a new set of plugs going for these days?

Congrats! Best bang for the buck for these platforms is hands down, a tune!

Enjoy your newly (re)discovered power!

.

3.99 each for SP534's at Oriellys.

Got done with the install, the car already had the colder plugs, but I went ahead and installed the new ones since they are gapped closer. I Took the car to the track and it dropped .5 sec, down to a 13.3@103(4300DA). I'll be close to 12s on some race fuel and the 93 tune. Thanks for the help gentlemen.
