This is a GMPP LS376/480 controller (E67). The cam, heads, and intake have been upgraded since the the original LS376/480 went in the car (a Miata).
I'm trying to get the DFCO to work. This is mostly a street car, so I want the best mileage out of it I can get.
I think the best place to look at the attached log is 42.3 seconds in ... according to what I think I have in my tune file, the DFCO should be active. What I suspect is that maybe my understanding of where to set the TPS thresholds is wrong. There are a lot of ways to read the TPS, I'm not sure which is supposed to be used in the DFCO control tables. I did try setting the DFCO enable value to 100 (of 200 max), and even that didn't work. Maybe the throttle has to transition from 101->99 for this to work, not sure. But I'm not using anywhere near that much throttle around here that time of year on mostly wet pavement with a grossly overpowered Miata.
I attached the log and the tune. I have a screenshot of the most obvious area of the log where DFCO isn't activating... 42.3 seconds in.
