Hey guys. I was in the market for the best "all around" OBD Sensor. I need it to set the tire size on my 09 Jeep Wrangler JK and possible gear ratio in the near future. I was also hoping for it to work on my other vehicles as well, when needed. Don't want it limited to the Jeep. I have been looking into the AEV Porcal and Superchips, but those seem limited to Jeep. Any suggestions? Thanks.
