Okay, well, Not sure where you are getting that info from, but of course the devices are going to be vin locked per car, that's pretty standard business practice or they wouldn't make any money.
1. The reset files for the EK devices are around 75 dollars to Unlock the device to be used with another vehicle, not 200. The process can be found on the old site here, as I cant find it on the new site yet -
ek1.sxthnk.com
2. The EK1 Pro/EK1Lite are the only devices on the market that can flash tunes to our cars. Sxth and SXThink Literally built the device themselves and Can charge whatever they want as they have the monopoly.
3. Even after purchasing an EK1Lite (599USD), a ECU (500USD) & TCU (300USD) tune is still less then a single Lap3 ECU, Just barely more than a Lozic ECU, and comes with support from the Sxth team so you can get revisions done, as well as if they put out an updated for the tune, you can download the updated version for free right from their site.
4. The devices Not only can do logging as well, but it can hit more sensors than the JB4/Lap3 pro tuners can, allowing for more data to be tracked and used to modify said tunes accordingly.
5. Even after all of this stuff, if you want to use it to flash a friends vehicle, it would only cost 75ish dollars to get the device to read their vehicle, then another 75ish to get it back to your car.
All of this from the comfort of your Drivers seat. So you can not buy one if you want, but that just means more for the rest of us. Gotta Pay to Play.
