Was reminded about this app I had on my phone this morning.

Been tuning with the PVCX again lately and I've changed my fueling/AFR which caused it to throw a code on startup (3056-2)
Nothing too major...just saying that front O2 sensor had a signal fault.
Has happened before when changed fueling but usually only pops up a couple of times before ECU gets used to new readings and goes back to normal.
Is quite handy for occasions like this to at least be able to search the code and get a little piece of mind as to whether it is minor or major issue.
