Ran my personal best recorded 100-200 (~8.6sec) in the 4th gear log, we were 2 people in the car and had secondaries welded back, usually I'm alone for my 100-200, but in the otherhand ambient temperature was cold, so it's a big help (3-5°C)

(And still exact same flat road)

3rd-4th gear log : https://datazap.me/u/studio54/log-16...=0&data=3-5-22
(100-200 ~8.8sec)

only 4rd gear log : https://datazap.me/u/studio54/log-16...=0&data=3-5-22
(100-200 ~8.6sec)

I had some timing corrections (more in the 3rd-4th), other values seems fine (?), but I have some lacks of understanding about "Timing Cyl Crk".

Concerning my blend, I don't recommend anyone doing this, I don't know exactly what are the 4% left in those bioethanol for fireplace bottles and if it's harmful, but it was one shot to reduce my CO at the tailpipe test.
Very impressive times mate,

That's actual cylinder timing which varies but upto 7.5 degrees is pretty good in my opinion.
