Professional insight
Tuners pick the ACES formula by engine and boost. Then they log results.
- Two-stroke engines need the separate IV-2S formula.
- High boost or compression may need the IV-P race version.
- Log knock counts before and after, not seat feel.
- Never retune timing based on octane claims alone.
