Maybe if you had four (or six) of them for individual cylinder information.

When I want a ballpark average, I glance at fuel flow.

To his point however, you really only need to test one cylinder. As VE goes up, AFR will lean out... No "false peak" like using EGT.

Not sure what the plenum side of Caleb's induction tubes look like, but in theory it should be easy to add a rubber coupler and a tulip to extend inside. Start out real long and record AFR, Land, remove an inch repeat.

Caleb, we took your feedback on the 255-0 wrap-around and incorporated some new code to prevent that on the MAP and RPM fuel parameters. This will be standard in the next software release V29.2. Thanks for that, good idea.

Life is interesting in NW California right now. Our main highway to the south is closed due to a rock slide, and not due to open for a while. I took a friend home to Little river (LLR) in about 35 minutes vs the 5 hour detour drive it would have taken. From there I flew to Crescent City CA for a work meeting, and back to Eureka. First time I've gotten to really do some X-C flying with the new engine setup, and a beautiful day!

I ran all ROP this flight. I am skeptical of the accuracy of my Grand Rapids %power display. It is programmed per their numbers for an IO360, but I need to verify them against some lycoming charts.

That's nice scenery you get to fly over. Us inlanders are jealous.

Took a flight over to Chico, CA this weekend with a friend to eat lunch at Sierra Nevada brewing. We also stopped in Redding CA for a quick visit. The food was fantastic, Northgate aviation at CIC was happy to let us borrow their ford focus. Outside temp was right around 100F at both destinations. I could almost feel heads turning at both airports after the effortless EFI hot start. Cooling seems good. I was able to climb out at WOT, 2500RPM and 120 KIAS while keeping all CHT's under 400 degrees. My cowling does have some extra outlets cut in it from the previous Subaru setup.

Just sneaking up on 40 hours of flight time on this setup, and still very pleased with it.

Wow, you're building up hours quickly Caleb. Thanks for the report.

Did some flight testing today. To keep things simple while I've been dialing in fuel settings, I haven't experimented much with timing until today. With a borrowed map from Toobuilder shown below, I noticed an immediate and apparent improvement in mid range smoothness. I'm also amazed how much timing the lycoming likes to idle smoothly. As expected, the engine is much happier lean of peak.
I am also tweaking on my fuel map for a "heat soaked" start up. For about 20 seconds after start, the engine will run slightly leaner until the intake system cools down I'm presuming. I have been experimenting with a larger value under the "start cycles" setting, as well as some added fuel at higher engine temperatures.

Caleb
