Ah a wonderful tool and brings backs great memory's racing methanol injected dragsters.
Used a Uni syn to tune the idle on these kinsler magnesium
stack injectors. After a while I could hear when it was right and used the uni syn to check my work. The engine cackled just perfect at idle and you could hear when it was right. Then when that happens the plugs are all heated more evenly at launch so the engine makes immediate horsepower and revs faster.

This is my second injected dragster, 632" donovan big chief pontiac 1200hp without N2O in 1993.

451" hemi.
