      thanks Apex- you said pretty much what I would have.
      truth be told- I don’t really compare the S2 signal with the S1- I just showed that in the video for example.
      there should never be an oscillation in the S2 so whether you have a standard ZiO2 oxygen sensor or an A/F sensor as S1, it makes no difference. the rear sensor either oscillates or not and if it does, it’s because their is no catalyst activity. (Remember even though a A/F sensor doesn’t show oscillation, it still occurs. this is evidenced on the STFT in fact).

        I would definitely start with the secondary air pump code first- and the first check would directly testing the pump itself for operation. seems everyone jumps to replacing the pump but Pretty much half the time I find the pump works fine and the valves or solenoids failed.
        get the AIR working first and then see if you still have the misfire codes.

            If anyone else notices they were billed twice, contact me directly at erwinschrodingersbox@gmail.com and I’ll process the return immediately.
            Again the issue is with STRIPE- the credit card company, not the website so don’t worry- no data breach or anything.

              Sorry about that- it’s an issue with STRIPE which is indeed secure. Some users (about 25 of them) were billed twice.
              I made stripe aware but no security threat.
              I’ll process the refunds for both of you right now.

                First thing I would do is induce lean and rich conditions to see if the O2 sensors respond appropriately.

                  What design is it? Inductive or hall effect?

                    You need to test fuel pressure bopth static and running.

                      AGreed. I am working with the IT team to make some better modifications. I too am unimpressed with the searchability of the site and it will only get worse as it explands. I will work on these and other improvements over the next few weeks.

                        I really like the Launch CRP Touch Pro but for a beginner really any LIVE DATA streaming tool will work as a start
