tips:

When you fill it up, make sure it's around 1/4 of the tank (or less). The first few tanks may be wonky for tank calculations -- for me it overestimated my MPG by a massive degree which is why my fillup adjustment was +12.2%. My last refill the SG was off by +0.1gal so now my adjustment is +13.3%.

If you intend to do any forced autostops or engine-off-coasting, use HYBRID mode but that may not work all the time. The SG prefers the engine running than not to function properly.

Deceleration fuel cutoff (DFCO) is calculated when your engine loop is OPEN, the rpm's are above the cutoff limit plus above the idle throttle position selector*. You know if you have DFCO when your MPG = 9999 or the GPH = 0.00 and most modern fuel-injected vehicles do have it

*idle throttle position selector = when car is idle, the current TPS value

I followed the manual's recommendation and set the "FUEL CUTOFF" value to 14, which is 4 above my idle TPS (10). I note this because I've seen a lot of people confused by this over on CleanMPG so I figure I'd kill the beast before it got loose.

You can make your own customized gauges called Xgauges.
