If you're rewiring your car or at least wanting to do a major update here's what I did and it's been very nice.
1. IQ3 logger dash
2. Smartwire with programable switch panel
3. MSD Grid with CAN bus for O2
The IQ3 logger is more money upfront than the other options but I removed all my gauges to clean the car up and you don't have to run a separate data recorder so it simplifies the setup. The MSD Grid has a VNET to link it with the IQ3 so you can log everything the ignition is doing along with the typical Racepak VNET transducers. The Smart wire and switch panel is programable so no setting up relays and running a bunch of wires everywhere.
To save a few $ I used MSD's O2 package vs Racepacks and bought my sensors from lowdollar motorsports.
