TCU-reported current gear

The ECU reads current gear from the SST TCU over CAN. Through a shift, it selects the new table pair when the TCU reports the new current gear.

Follows your ROM’s boost mode

Factory load-based definitions show targets in load units. Matched RAX Direct Boost definitions show targets in psig and retain the ROM’s barometric and boost-error corrections, IAT WGDC correction, upshift logic and logging. RAX is supplied as a separate included XML.

Native boost fallback

The original ECU boost tables take over when Boost by Gear is disabled, a forward gear is unavailable, the gear signal times out or the boost mode check fails.

Boost By Gear Functions

Each gear gets two editable ECUFlash tables. WGDC is base wastegate duty cycle in percent.
