Just got my kpro and trying to learn on it without messing it up. My car is an ep3, cai/rh/e with the hi octane tune. A/F when floored is 13-14 to 1. When letting off to 0% throttle it jumps up to 32.67 and is red. Wasnt sure if this is normal. Hopefully i can learn some more on here before further messing with it, just a lot to take it at once.

it is normal. nothing to worry about.

if you let the throttle off you will only get air through the engine without any fuel. so you will have, for the wideband, a very very lean mixture.

there is, for sure, nothing to worry about. just let it be ;)

best regards Luke
