My SG did something really weird today. I DFCO'ed down to a stoplight. Once I came to a stop (SG did not report DFCO when I was actually in cutoff) SG reported 9999 MPG and 0.0 GPM fuel rate until the light turned green and I hit the accelerator to go.
For those of you unfamiliar with my SG calibration problems I can't seem to get SG to report DFCO.
There are problems with the SG when it comes to dealing with FAS and EOC. Even with "hybrid mode" selected, it doesn't always work right and from what I've read, there is no immediate solution other than not to do FAS/EOC.
