Let's see your fully tuned timing maps
Just looked through the log - yes it recorded a knocksum of 2 in that cell.
Actually I was running up to 8* at peak torque, but it tended to knock sporadically, so I took out a degree or two from the map.
I 've been running stock block 2.0l + 272 kelfords + stock evo9 turbo @ 25psi peak tapering to 22 psi and 6-7* at peak torque for 3 years of daily driving + autoXing. I wasn't really worrying about my stock rods as considered my tune to be pretty reliable, as my engine never failed even at competition events.
I never worried until one day I went to dyno and saw some numbers. It made about 450lbs\ft of peak torque on pump gas RON98 (92-93octane probably) at 7* and 470lbs\ft using WMI system at 9-10* at peak torque.
What really wonders me is how he runs 7* at peak torque on 91 octane?

My car won't take more than 4* at peak torque without knocking. But it's car and fuel dependant.
It's an odd map, timing numbers that make sense are starting at 7000RPM.
Try my smoothing tool to solve some minor rollercoaster issues: https://www.evolutionm.net/forums/ec...t-version.html It's for bigmaps, but with proper copy paste you can use it with small maps. You can use it only to search and find the odd timing numbers.

Much better!

Well, Here's what it did...Top = Before. Bottom = After

Use 200Load-1750RPM To 300Load-11000RPM (copy paste)
It has made your map smoother in that area while solving the up and down and up timing issues.
Low cruise timing. This leads to bad MPG.
Low tip-in timing. Maybe it spool faster, but that surely isn't snappy.
However it's a nice 91 octane number (443whp).

Different strokes for different folks.. our 91octane won't allow any more mid range timing so I run it leaner and help it spool there at 12-16psi I am at 11.8 afrs I am pretty sure I know our fuel better than you do. Its as bad as CA 91 nevertheless I will be switching to e85 next week now that it is readily available
