Based on what I've read,I suspected this would happen. Now I get to fill my engine and exhaust with fuel. The car ran strong and perfectly before the install. It's a unit from the first batch Bob made so I tried to update before starting and was unsuccessful.It farts in the exhaust so I moved the cam sensor and was able to get a full blown backfire in the exhaust or no fire at all. In Bob's update instructions he says you can turn mode switch 2 on while the ignition switch is in the run position and it will blink the version of software,but all that happens is the Trig/Error LED blinks once. This is the message I get when I try to update.
