DTC in Datamaster, CPO2 < 54ms ? what is this?
I did a search and only found 3 threads with COP2 in them, non had an answer for the problem and they were in 2001.
305TPI with 730 ECM $8d
So, This DTC is toggeling back and forth every sample that datamaster gets and it make the laptop beep each time. Even at one sample a second this is happening? anyone have any ideas?

That is the watchdog timer in the software to confirm the ECM is processing the code properly.
I think you have a bad burn.
