Another small update but nothing much to report, last night I had intended to swap over my coils and plugs before logging the car both before and after removing the WMI connection to the MAP sensor but I'm still waiting on the seals for the bolt-down coils from TPS. Hopefully these will arrive today.
In the mean time I tarted up my lights with some LED replacements for the rear number plate and sidelights which are a definite improvement.
I also ran some logging on blocks 118 and 020 as before (with everything still connected) and found some really strange behaviour. It seems there are intermittent communication issues causing errors; at one point all readings for block 118 were in red and read ERROR for Absolute pressure, then I had a warning dialog for "Too many communication errors" and on one occasion Absolute pressure read "Cold"
CFs also gave some intermittent weird outputs, and I'm not sure how much of this is down to the flavour of VAG COM I'm running... When these errors appeared on-screen the subsequent logs that I'd saved show time gaps where nothing was recorded.
Aside from this I did see Absolute pressure register more than 1000 mbar but while it's still misfiring under load there's not much I can really take away from these latest logs. I guess a broken MAP sensor could attribute to weird readings and communication issues in VAG COM, but then so could the WMI controller tapped into the same wiring.
Once I've changed the coils and plugs to hopefully eliminate the misfires I'll try logging again with the WMI connected and then disconnected by cutting the wire to see if there's any difference. If not it's going to be a painful exercise of checking all the wiring to the WMI controller...
