TT Exhausts

Thanks Cobber
I'm having real issues getting my mac to talk with the MEMS3 unit I have tried multiple times and it isn't working. Phil if you are out there i need your help as I'm running out of time (and patience) with this. The port number does not come up! The green light is flashing everything is as it should be but the PSCAN software just isnt engaging. No port name !
