The MAP also looks a bit high to me... Have found the latest logged run I did, yours is at 89, mine for similar RPM was in the 50-60s. Unless you were under load then it shouldn't be that high.. The higher the MAP, the more fuel it will inject, which kind of explains the sooted up plugs.. but why is it that high?
Duty cycle of zero is not right, however I'm having trouble finding a more recent log with the bigger injectors. Have you reloaded a good map? I'll send you some screenshots and one of my more recent logs directly, and in the mean time fire up my laptop to see if I can find anything saved there (however did have a hard drive crash not sure if there is anything on it.)

The ignition timing map was fairly constant at low engine speeds and loads so it's possible that would stay at 13.9 for the run you did for the log. Hmm, Gve (Gamma volumetric efficiency) seems to be stuck at 255, this is looked up from a table for the fuelling. It doesn't sound right. Can you download the current map and send it to me ? And it would be worth trying to reprogram it with the last map you have saved on the PC Jim On 08/11/2015 12:18, Robert Craig wrote: > Lots of info there to be looking at.
