Ok so here's the deal. My ethanol% keeps going up and down which makes my AFRs do the same thing. I emailed Jared and he emailed me a license update to enable me to tune my truck. Basically he sent me the $200 upgrade for free for the time being so I can adjust my fuel trims to 100. Anyways enough about that. Like an idiot after I updated my license and flashed the new base tune he sent me I went to Uprev.com and downloaded the Osiris tuner installer. At the very end of the install it did a software update I read on the FAQ's from their site that a software update will over ride a uprev license. So now when I go to cipher it will not communicate with my ECU. I emailed him back so hopefully he can send me another license update. Has anyone else ever done a software upgrade where they lost their license or am the first idiot to do it? Thing is though, it will still let me flash different roms with no problems. cipher even opens up just doesnt communicate while in there.
