Just got a link G4X yesterday, powered on and could connect to it
Tried to use it today and it wont connect
With key off and acc light on ecu comes on, key on and light turns off
Only thing that changed is I had it on trickle charge overnight (Yes had positive and negative the right way)
Engine isn't currently in the car but was working fine yesterday
Have tried reinstalling pclink and yes its the right version, have also tried unplugging ecu and battery to reset it but no luck
