AEM 30-2310 issue

I'm having an issue with an aem 30-2310 wideband in an 09 CTSV. The wideband reads fine in the datalogger at idle and at cruise, but on a full throttle pull it loses signal at times. For example it will read perfectly if you just make a one gear pull on the street, but on a full 1/4 mile pass it will cut out and just go to full lean after a couple of gears and stay there. The car isn't really lean though.

Has anyone else had this issue with logging a wideband? I'm thinking it may just need a better ground or something (currently grounded to the chassis), but I don't have the car here right now.

my friend, you might make for certain your not going too lean and pump some more fuel in to make sure. also checking for loose connections would be wise aswell

where are you getting your voltage from?

these gauges (sensors) operate at a max of 5v
