Glad you see the value in the FIC... It really is perfect for a low boost / boosted daily driver application. Just so you know, I also have an automatic so those base tunes should be even better. Of course there's a huge list of variable that will throw off its accuracy, but it's a hell of a lot better than starting from scratch.

Things you NEED to monitor: Oil pressure, water temperature, AFRs. You also need a code reader. Boost/vac is also important, but not required. As for the tach - you don't need one but I'd recommend getting one. When you're tuning the FIC learns the signal relationship between the cam and crank sensors to determine RPMs. So while you're datalogging you'll still be retrieving accurate RPM data.

As for the tC since you asked - that's running a Motec ECU. It's great and the tunability is awesome, but it's a PITA when it's giving me issues because I don't have direct access to the tune.
