Re: CAN template for AIM data system

UPDATE from Gen3 testing: Got the AIM system connected to the Gen3 in time for the open test day at Thunderhill this weekend. Note that I did have to ask Enterprises to send the other end of the ECU CAN-BUS plug as it's not provided by default in the Gen3 kit (male side). Need to add a 100-120 ohm resistor between the CAN+ and CAN- wires when you wire up the CAN-BUS plug (don't trim it too much as I nearly did as the pins need to be pushed in a quite a ways.) Thanks, Dave Ferguson, for the assist.
I immediately had all the CAN settings available from the PE3 once it powered up. I did have to fiddle with the default ranges on some of the setting provided as some of the defaults were out of range (e.g. Oil pressure maxed out at 14 psi, and Lambda was configured as psi but actually returned Lambda values (decimal value with 1.00 being equal to 14.7/1 A/F ratio). Data was captured correctly so it's only in the display that it mattered. Easy enough to set up a math channel to convert to A/F ratio if desired.
Now, if I can only figure out how to get the PE3 software to connect to the ECU!
