haven't made any changes to the tune but all of a sudden my MTX-l WB is reading richer then it use to and giving somewhat more erractic readings. ive had it in the car for maybe 6 months and only free air calibrated it when first installed. heres a datalog and my tune.
Thanks yeah cause from the datalog everything else seems normal my Pw and dutycycle at idle is inline with my normal readings just the wideband seems off I’ll re-cal it tmmrw when it’s not raining here and report back
So I had a really hard time re-calibrating the sensor it kept reading error E2 and I checked the resistance of the pins 3-4 on the sensor it read right around 3.5 and the heater circuit had voltage. I finally got it to calibrate but it still seems a bit off on readings from what it use to be. Next step is to order a brand new sensor to see if that fixes it.
Update , I changed out the sensor with a new one and all is back to normal reading wise. Here’s an alternative sensor that I’m using https://www.amazon.com/gp/aw/d/B07K1SMQYH?psc=1&ref=ppx_pop_mob_b_asin_title it’s a little cheaper then the Bosch and they will replace of defective and seems to be working perfectly.
