I have been driving the car on the stock tune for the second day and it feels healthier. Throughout the RPM band its obviously slower but it has like a harmony to it, I can feel there is no monkey business going on with it even though from the logs, you can see its heavily closing the throttle.

There was also sometimes a drop in rpm on the LMS tune when i would be coming to a complete stop which would cause a bit of a vibration (rpm dropped) and the rpm would then jump a bit past idle and calm down to a regular steady idle. I can't reproduce that on the stock tune.
Mine does that goofy idle drop as well.

Mine used too until I had my strategy updated... no longer does it do that.

Mind if I ask what strategy you have now, and how/what did you tell the Dealer to get them to do the update for you?
I am on KHDK4, and one tuner had mentioned it might be nice to make sure I am on the latest strategy. When I asked the dealer they pushed back saying no reason to do it.

I know mine idles low and bounces around a bit at idle.

Tell them unless they would like to make your car payment then doing what you ask is all the reason they need.

The original strategy for my 2010 SHO was DMJK1AB and then after several updates it is now at DMJKBLA. Livernois had to "build" a new tune for my strategy since I was the first one with that strategy to get a tune.

The first dealer I went too flat out refused to perform a strategy update. The dealership a bit further down the road didn't even question, they were more than happy to take my $100....

Thanks!! And Is that what you asked for "strategy update"? With my goofy Idle I can probably use that as a reason to get my local shop to do it.. "I was told the latest strategy fixes some random idle issues I have been having..."

:-p

StealBlueSho · April 11, 2017, 05:27:23 PM

Exactly... the Ford dealership I eventually went too understood completely what I meant when I asked for a strategy update...

The service advisor wanted me to come back once I got the tune put back on so he could ride in it lol...

They also sourced me a new HPFP when I was trouble shooting a fueling issue AND price matched it from an online dealerships site...

I planned to throw a usb cable in there but it didn't physicaly make it inside the box lol. Can't thank you enough for aiding in that discovery, I hope you don't miss that one vin allowance!

I would like to thank everyone with their 18 pages (so far) of support. Take a minute to get to know my car tinkering roots a little better as I see many of you as friends.

Had a little business with my brother Dave designing and fabricating a replacement part for one that Trd/Vortec failed on.

Looks like a completely normal stock log to me.... geeze...
Can you post a log of your latest LMS tune? It's crazy that our cars are so similar all the way down to the transmission.

This is the latest one I have from a LMS standpoint.. 4+X... the only difference with the newer tune is a softer shift... which honestly... isn't exactly soft, just not bone crunching and feeling the the tranny is going bang itself into oblivion...

Sorry bud :-/ Any word from LMS?

polskifacet · April 12, 2017, 04:29:27 PM

Nope calling LMS on a daily basis at this point and not getting anywhere.

SHOdded · April 12, 2017, 05:16:38 PM

With everyone thinking engine, the transmission is the wild card here. Or may be a flaw in the PCM strategy. Any way to get LME to get an engineer from Ford to look at it?
