The innovate mtx take about 30 seconds to wake up when I first start the car (95 turbo miata) I have the car running in open loop for idle and I'm fine with it. My question is for that first 30sec or so my car is running super rich on tuner studios wideband signal like 8.5afr what do I mess with to get the car to run 14.7 upon start up and why is the innovate wideband so sleepy none of my arms act this way?

 

My MTX-L does the same thing. I believe it is not reading until HEA is replaced by a number on the gauge, so it's not really down at 8.5 even though TS shows that.
