Last week I took my car for some work and I mentioned to my SA said that my car runs heavy. After few days of working on the car, I got a call that my car is ready. While at the dealer, my SA that there was an update to the ecu which they performed on my car. Now while driving, the car seems like it's lag free with an acception of little lag while the tranny is learning.
what I noticed in the loaner when braking hard and then accelerate, the car would go in rev matching like it would in DS. I tried on my car after the update and it did the same which before it did not.

Over all I have driven about 30 miles with minimal lag and hoping that it'll get better as it adapts to my driving habits.

bear in mind that i did have the tranny TSB performed when it came out long ago. I had no idea there was another update.

Anybody else know of this update?

 

its prob the update the 2012's got which is what Ive been saying for a while Glad to see someone else experience it

 

Is there a specific TSB # for this upgrade? I had the 75TSB Reflash done in June but it's still having some of the AT issues, better but not quite right yet.

 

all it said in my service receipt was that ECU update performed.

 

What year is your car?

 

My car is 2010. Today I took it out for a ride and man its so much better. The lag is to min.

 

Good luck. Let us know how you like it after a couple of weeks driving in different traffic conditions.

 

Ditto. The upgrade is great until it goes into the learning mode and reverts to some old, bad habits.

 

subscribing to this. maybe they finally fixed it... from what I've heard as well the 2012s, despite being exactly the same, is like a different car.

 

This lag that you're talking about, what kind of lag is it? I'm new at this car (I previously had a 2000 Mustang) but ever since I got it I notice a bit of lag when I punch the gas pedal to the floor... Is this normal because the car is readying up to go full throttle? Just wanna clear up to know if my car needs this as well... Thanks

 

It seems the TSB # may not be useful unless there actually is a new one. Maybe we can start documenting the actual characteristics of the ECM and TRANSMISSION updates. Surely there is something about them that we can use to uniquely identify them: file size, software version number, file date, release date, etc. Does anyone have a good enough relationship with their service department to investigate?

 

Guys,

Had my 2010 sedan ECM & Trans flashed yesterday and it made a big difference, the car accelerates much better.

Technician's notes were??

 

I'm a little confused about the AT/ECU flash I've got a 10 G and have been debating getting it done. But on the other hand I think my AT shifts just fine don't notice any lag unless RPM's are at 1000k and I Romp on it, But that's almost to be expected if I'm getting ready to floor it I'll grab a paddle and downshift a few until my RPM's go up then put the hammer to it guarantee no lag. Also I've heard several OP's on here say that after the flash the AT actually performed worse than before. I think those of you boasting about a miracle cure for your AT are suffering from the placebo effect!

 

Reseting the ECU, my car drives great. But then slowly the lag and hesitation comes back after a while.

Keep us updated on how your cars are driving after a week or so.
