Default Open Loop on Deceleration
Have a small problem on a motor recently installed. I notice on my scan gauge a shift to open loop when decelerating at highway speed.

Any ideas? I was thinking maybe a vacuum leak or something.

Nope, open-loop on deceleration is perfectly normal and expected. Open loop also kicks in under full acceleration.

Agreed, it's shutting off fuel injectors on deceleration. No worries.

That's what I read on a Toyota forum but the odd thing is that my other 3 discos don't do it. Are you guys running Ultra Gauges and show this?

I am running an UG. Had one on a 2008 Jeep as well, did the exact same thing on deceleration.
