    suppressing flames during WOT shifts?

    Gents,

    working on a blown race car which spits flames during WOT upshifts when hot. This is upsetting track officials albeit it looks cool for everyone else. We are running 100cell HJS race cats though.

    don't want to go any leaner then AFR 12.2, tried with AFR 13 but it only makes flames hotter more bluish in color.

    played around with DFCO and CFCO settings, upped spark entry, lowered this and that, nothing eliminates it to just like a little spit. I'd assume possibly working with transient fueling might help but unsure about what to change.

    any inputs (except flames are cool )
