Looking for anyone who has installed the SEPST, loaded a base map, then did their own tuning using the Smart Tune feature w/out a dyno. I've been running the TFI for 2 yrs now and very happy, but curious about the Smart Tune feature where you record for 15 minutes, upload the readings, let the ST feature re-do the map, then flash it back into the ECM. Also, can anyone confirm if the softward/tuner is compatible with Windows 7? I'd assume yes, but just confirming. Thoughts appreciated before I call the dealer to see if they can match LSHD1. Ride safe and have fun.
