- Engine enthusiasts and combustion-simulation tinkerers
- Worth noticing
- The data log records what the ECU sees for the last 90 seconds and can export logs as CSV.
Field notes
Builds can be started from the current engine or a bare block, saved, copied, renamed, and reset to stock. The simulator lists leaderboard categories by engine type, displacement, and distance; publishing a build is described as triggering a server dyno run before its power figures are shown.
