C43 engine light with Jb4
Twice this week I've thrown engine code 2177- which looks to be " system too lean off idle bank 1"
I have a 2018 c43 stock except for jb4 tune usually running map 2 with a 25% e85 mix. Any ideas what could cause this. I do have the jb4 green wire under the airbox connected also.
Anything in the logs I should look for?

the two times it happened thus far were seemingly random. once while under normal driving/low rpm and once after a quick blip of the the throttle . I'll see if I'm able to grab a log if it happens again.
