Hikari Speed 光 - Alpha v0.04.1
Added 2025-04-02 20:14:53 +0000 UTCIntroducing Hikari Speed
Lore: Founded in Japan in the mid-2000s, Hikari Speed 光 was built with a singular mission: to make Hirochis faster. Commonly referred to as simply Hikari, the name — written as 光 — translates to “to shine.” And that’s exactly what your Sunburst will do when equipped with our performance parts.
Updated 8/21/2025
This is a big one.
Hikari Speed v0.04 remasters the ECU "Bench Unlocks" from the ground up, bringing a host of new and unique features to all three Sunburst engines, unlocking a new level of performance and control for the entire Sunburst platform. For features, this update to Hikari Speeds ECU software introduces multiple wastegate control strategies, a street-optimized anti-lag system, variable burble settings, fuel map selection, and a completely overhauled tuning menu UI with Unicode visual categories.
The Bench Unlock of course compliments the also newly remastered Street Turbo Package, now available for 2.5L AND 2.0L. Among new visual and performance options is the addition of an all new Hybrid Turbocharger, that when paired with our new forged internals and E85 fuel maps, can reliably push 500+ bhp on the Sunburst RS.
And that’s just the surface.
