EDIT June 10th - See post #13 for preliminary performance results. Woo Hoo. EDIT June 11th - See post #28 for OBDII Emissions Monitor Readiness - Before tune and after tune EDIT June 11th - See post #29 for The Tune Workflow Ok, here's the disclaimer. This is how it went for me. There's no guarentee that your results will be the same. Making any mod to your vehicle is at your own risk. If you make any mods, your vehicle could be damaged, and it may never pass emissions testing again. I hope this thread will be of interest to those thinking of doing a tune, but who have no experience with this type of mod. I'll post updates to this thread as events unfold. I ordered from LMS on Monday, received my LMS MyCalibrator unit Thursday evening. The XSport was at the dealer (I bent the left front strut - another story for another time) until Friday afternoon, so I was only able to send my strat code and SWID late yesterday afternoon. Great, proactive communication from LMS to date (thanks Jaimie). First step was easy, retrieve the strat code and SWID from the XSport and email them back to LMS. 1) Being the **** person that I am, I followed the LMS instruction sheet for a tune upgrade even to retrieve the codes (turned off a/c, radio, auto-mode for lights, etc). With ignition in acc mode, I plugged the tuner in following the instructions to place the tuner in engineering mode. Then I followed the menu as displayed by the tuner and emailed the info to LMS. Nothing to it : Here's a typical 0-60 time for my Sport before the tune. Don't know why it says 2014 in the heading, it's a 2015, I'll check the settings in Dash Command. Ignore the quarter mile, reaction stats, etc., I was only going for the 0-60 time. No power braking, normal drive mode : More to come as soon as I receive the PC tuner program and the tunes. So far, so smooth.
