I'm using an Innovate LC-2 Controller and gauge.
It's my understanding that when I KEYON, the sensor is heated and the controller goes through some form of startup and will not report an accurate reading until the sensor heats up. It seems to take ~20 seconds for the gauge to display the actual AFR.
If my engine reaches operating temperature (~180), then KEYOFF, and immediately KEYON, it takes another ~15 seconds for the Gauge and TunerStudio to report the actual AFR.
So, from my perspective, the sensor should already be at a sufficient operating temperature. Which leaves me to believe that the controller is taking ~15 seconds to "boot" up, which seems like an eternity.
When I called Innovate Tech Support and articulated this observation, they said that this is the expected behavior. I attempted to glean out more details, but the Tech could or would not provide any details and audibly became agitated, so I thanked them and moved on.
If anyone can help me understand "WHY" this delay exists, I sure would appreciate it.
I'm new to MS and while it's Cold here in Texas, I'd like to work on my WUE.
Thanks in advance,
-D
P.S. If it seems that I'm splitting hairs and/or this delay is insignificant, please shoot straight and tell me to drop the ball. I will let it go.

Re: LC-2 Controller Delay in restart
I would not expect any wideband O2 controller to report accurate AFR data immediately after power on no matter when it was shut down. A 15 second delay seems reasonable to me.

Re: LC-2 Controller Delay in restart
Hi,
based on Bosch recommendation the ramp up rate for the heater voltage must be maxiumum 0.4V/s.
If the heater control meet the sensor manufacturer requirements, we need at least min. 10s to arrive to approx. 90 -95% heater power for fastest heat up stage, but this does not mean the sensor is at operating temperature yet.
I agree with Jean and the 15s is realistic.
Attached the corresponding part from the sensor datasheet.
