wideband not accurate

Post by turbotypeR »

i thought my plx sensor was bad, so i got a new sensor and it is still reading lean. it was reading really lean around 20-25psi(2nd or 3rd gear) and read closer to what it was on the dyno(around 12:0 to 1 at all boost levels) in 4th gear and higher boost. on the next pass, i added 10% fuel and it was so rich it broke up. the datalog read 10.5 then and still broke up really bad. here is the calibration and the datalog from when it read lean and when it was breaking up:
