At 1min DFCO works and at at 2min40 the TPS not being 0 prevents it. Could be a setting, a mechanical thing or your foot ever so slightly on the pedal. This is at 1min and shows DFCO working.... DFCO.png Weird. With the stock memcal my fuel usage goes to extremel lean and my instant fuel says 0. On...

When completely off throttle my wideband sits in the 14s with instant fuel using 2.6l an hor. On stock tune the revs go to 1k and says 0.0l per hour

I posted the log. Was just wondering if you can get decel enleanment on a VT aswell? Cruising without throttle at 80km uses about 2.6L per 100. LGBT throttle isnt bad using about 6-8l per 100. This is on the instant fuel usage

Good idea.

You need a VSS for DFCO to work.

Just looked at one of my logs and yes it shows VSS and TP

I've tried uploading a new bin but it still doesnt work. Any ideas?

Is there any benefit to using the timing map from a VY l67 in a VT? Thanks

The 15 range will improve economy by 1-2% as 17-18 is a bit too lean and torque starts to fall away. I set my road speed somewhere around 30 or 40, temp was about 60 iirc, what ever the min temp where all the spark and fueling tables/scalars were at normal operating range. In some tunes I disable l...

yes for the temp, also there is a time out setting before it engages after steady state cruising, default I recall was around 1 min, I set it to about 5 sec. about 15.6-16 is ideal, v6 can operate around 17 with no issues but generally gain slightly from a mid to high 15 range. Can i lower the road...

Just wondering if it's safe to set lean cruise to a road speed of 55 rather than the stock 70? In doing so is it also best to have the afr set to 15.4 rather than the stock 18? Will I gain fuel economy if I do this? Thanks
