I'm trying to e tune my k swapped k20z3 into my civic si 2000 but I am running into problems with my o2. Basically what happens is kpro will read the sensor off hand, it seems fine. but it will flat line on the graph and stop cycling As the car datalogs(dataloging from the ecu) And when I review the datalog it's super laggy as well. The o2 sensor is being read by kpro and it shows that it's there. It's a denso OEM sensor, tried 2 same problem. One thing I noticed is that the k tuned harness I have in the car has the primary o2 sensor plug and wire is longer than the secondary o2 sensor wire? Weird any ideas?
