Plus download the tutorial that appears in an earlier post in this thread. All details in there. Not difficult at all.
On terminals, where are you?
No gas. No FI. 08 Corvette powertrain.
Have used the COS to switch E85 in and out, plus select a different timing map and/or different fueling. So yes good for running some gas or FI.
Cheers.
