Not sure What version I have. its for a Subaru wrx 2.0 with coil on plug in a sand rail that I bought. having an issue with starting. computer has power and ground with key on but fuel pump wont run for the 2 seconds and wont start. If I turn the key on then off and back on fast it will run the fuel pump and start. checked fuel pump activation wire from computer same result dosent turn on unless key is turned on off and back on multiple times to work. is there internal relay or something on the circuit board that could go bad. I'm a ase certified technician and diagnose these kind of problems every day. This is my First aftermarket style computer. I don't have the cable for laptop yet. I have replace the ignition switch cleaned ground wires. jumped the fuel pump to run all time still wont start. will only start when the computer turns the fuel pump on and runs fine. the guy I got the Sand rail from sent the computer and ignition box out to have checked and said they were fine.  Also with the coil on plug setup and the ignition box what wire can I use for a Tachometer Thanks For any input or things to try
