On a warmed-up engine, if the ECU goes open-loop during no-accelerator coasting above a given RPM, does that imply fuel cutoff?
I didn't believe my VW Cabrio implemented fuel cutoff, but I've been watching loop status lately and now I'm thinking I was mistaken. It seems to go open-loop any time the accelerator isn't depressed and the engine is spinning faster than about 1400RPM. (Interestingly, this happens whether the A/T is in drive or neutral.)
Just wondering if that's a sure sign fuel cutoff is happening. If so, I need to tweak my driving style slightly.
Thanks,
Rick
