GTP091 Posted June 12, 2018 Report Share Posted June 12, 2018 Im certainly not a pro with TunerPRO. Was taking a look at the datalog last night just for shits and giggles. After getting to temp TunerPRO showed the ECM was still in open loop with a status of the cat 'not ready' ? After a bit more time I shut the car off, disconnected the ALDL, reconnected, started a new session, restarted the car (it was to temp) and it went into closed loop right away. Not sure if this is an issue with TunerPRO, this was just an anomaly or if my car is getting grumpy. Nothing was amiss other than this, all values seemed to be good. The O2 sensor has always made me wonder if it's bad. The only sensor that hasn't been replaced is the O2 sensor. I have a new Bosch o2 sensor but couldn't budge the original so let it alone, will change when I pull the engine for 5speed swap. The o2 sensor value was around 320-450 of whatever that value means.
