LMS tune updated v6 = less power?

So I picked up another set of plugs from my local dealer, and weird that these were already at 0.030. The other set that I got were allover the place. Some at 0.040, 0.035. I will take it for a drive later today and do some logging and see what happens. I'll let you guys know. Also you may want to have an extra plug boot handy, as I found out when one of mine decided to stay on the plug and I had to use needle nose pliers to get it off the plug lol. 
 
Remember when you could use a spark plug boot puller to assist in removal?  Well, I do :D  Hopefully this new set of plugs will do the trick :thumb:
 
^^Yes I do! ;). Is there any software that will show which cylinder the misfire occurred? The program I have only shows when it occurred not which cylinder.
 
If you can pull the codes, you should see p0300 for random misfire, or p030x for specific cylinder misfire, I believe.

I pulled the codes and the only codes I got was the mirror and the sd card being ejected. Nothing about the misfire,

There is a allowable amount of miss fires before it will throw a code.

Chris... does that means that no cylinder is identified unless it individually reaches the threshold for a code and otherwise it's a generic P0300 code if multiple cylinders combined exceed the threshold?
 
If the threshold is broken it will generate a code, and can generate a code indicating which cylinder is miss firing. Its all relative to the cause, where a random miss fire could have a cause unrelated to a ignition component. And merely a result of another problem. Where a single cylinder code would indicate a bad plug or coil. But as to miss fires all cars do it and miss fires occur about 10% of the time. But that great compared to the old days miss fires occurred a lot more often.
 
Interesting, well I have taken it out and it seems to be lots better, I also filled up the tank with 94 (again) and took it for a drive on the local toll road. And no misfires! (Stock tune) At least not yet and under heavy load. The guys at LMS were good enough to send over the v8 tune. I'm going to give that a try and see what happens.
 
My guess is that there was nothing wrong with the earlier  " bad " tune .
Somewhere in the file transfer or burn / rewrite  process it somehow got corrupted .
It's one of those things that occasionally just happens ..... gremlins maybe.
 
Great to hear!  Still would like to know the technical details of why the older tune was so prone to issues.  My guess is it is related to the Ford's ECU programming changes for 2013+ SHO's, and finer points still being ironed out by aftermarket tuners.  Everyone running the v6 version, at least on 2013+, should probably get the v8 version instead.

Let us know how you feel about the tune over time :D  Many, many happy miles of WOT'ing!
 
No, it doesn't do it with advance trac off. And it only does it from dead stop wot pulls. Not thrilled about it but I guess I'm ok with it, one other member has the same issue and LMS said that's about it for me, they said only solution would be to down tune it. And I'm only running 91 meth tune not 93, because 92 is the best they have at the pumps in Oregon.

Still wondering if there is another tune for me though?
