Dunno if it's good or not... but I doubt the fluid is my issue...I suspect tune related...

Update: it's been several days since I told Anthony at LMS what was going on...
Got an email yesterday confirming again that the sputtering happens only with the 4+X tune AFTER the transmisson learns the new parameters...
Still no new adjusted tune... Apparently my strategy is not exactly a copy and paste...
Shocked!!!!!! LOL...

My transmission misses shifts constantly, not only 1-2. Has happened in pretty much every gear, very intermittent.

Honestly, for 95% of the SHOs out there, their tunes work just fine. So in reality it's just that small percentage that don't, the odds are in their favor.
I'm not bashingLMS, just making an observation, and hoping that if someone else has issues, these threads can help!
My car has been anything but a copy and paste for ANY tuner that has worked on it. The only tuner thus far that has taken the time to dig through it, make adjustments outside the norm, and help me understand what is going on is Brad.
Granted, now that I am keeping the car, I will run with Brads E20 tune (which my car had different preset in the tables than any other 2010 he had worked on)however, I paid LMS for a tune, and expect them to provide a working tune.
That said, Anthony has been great to work with at LMS, and with their reputation along with Brad letting me know that my car is an oddity, I don't mind LMS taking the time to double check and make adjustments to my tune.

For me, no issue on stock tune. Something just has to be different with strategy/hardware combo that doesn't work as expected with the LMS tune. A custom tune can massage those anomalies away whether it be LMS or any other tuner.SHOdded said:
Update... LMS FINALLY got me an updated tune... Anthony said my 4+X tune was already modified for the issue they were experiencing before. However, they did modify the 4+x tune to soften the shift, however, the modification is such that I will not or should not notice a difference...
ANYWAY... I haven't tested it.. I am in the middle of dialing in an E20 tune with AJP... I will update once I get time to test...

Update for my issue as well, seems like traction control is the culprit even at WOT on the 3rd gear to 4th gear shift.
polskifacet said:
Really?! How did you verify this? Seems an odd place for traction control to kick in..
1-2nd I can understand, MAYBR 2-3 if you are in a turn or something... 3-4th? Nah...
I will caveat this with I have seen/read the electronics in these cars do strange things...

I had a bit of road to test this. 3 out of 3 with traction on, it would try to do the 3rd to 4th switch, kind of pause for a half a second, blow off some boost and then shift and proceeded to haul ass. 3 out of 3 with traction off, shifts normally. Only other "difference" I can think of is I have 18" winter wheels on but since they are all the same wheels and tires, should be fine.

No an inch smaller od. spedo is ~5 mph over actual
polskifacet said:
I dont know for fact...but an inch is alot in my book...i try to stay within.25" when switching tires without a tune change....the speed sensors will be reporting something different than what the ecu is expecting for gear and rpm so i could see it messing with stability control

Eventually once I get LMS to schedule an appointment for me, I'll ask them to provide a winter tune to account for tire size and we will know for sure. Annoying it bugs out, should be better code.
