EcoModder's, Sorry to bore everyone on here with these posts, but I'm using this forum to show my data/information to other people from different forums and social media. It's easier to direct them here to see my progressive timeline.


This photo is a normal performance A/F ratio of 12.2:1 running a single pre-chamber in cylinder #3. This is my hottest pre-chamber (number 1 on my heat scale of 5, with 1 being the hottest and 5 the coolest) Number 1 works well with boost below 20psi. This pull was at 36psi, and I intentionally wanted it to make knock. Knock started late in the rpm telling me that the pre-chamber center electrode heated to the point of self-ignition, and the #3 in-cylinder pressure sensor verified this. The internal nickel alloy heat strap indicator shows signs of degradation also from the heat, mostly due to its placement. The center electrode shows no signs of degradation. My next test is to lean out the A/F to 14:1 at the same boost level with the number 1 pre-chamber.
