Alphaspeed TCU Tune Service — 2013-2016 Genesis Coupe (BK2) 8-Speed Automatic

Tired of your automatic Genesis Coupe shifting like it's afraid to wake the neighbors? Alphaspeed's TCU tune unlocks the full potential of your BK2's 8-speed transmission — letting it rev out like a manual and shift with purpose.

Available in two stages to match your build goals:

• Stage 1 — Raises shift points so you can ride the full powerband, just like a manual. Also disables auto-upshift in manual mode so you stay in control.
• Stage 2 — Everything in Stage 1, plus significantly faster shift speeds for a more aggressive, performance-oriented driving experience.

Compatibility

• 2013-2016 Hyundai Genesis Coupe 2.0T & 3.8 with 8-speed automatic transmission
• TCU tune only — for engine tuning, see our Alphaspeed ECU tune service

Important Notes

• ⚠️ Requires an ECU tune adjustment — the stock ECU may hit rev limiters without it
• ⚠️ Some TCUs may trigger a transmission oil pressure warning light. This is a known Hyundai issue and is covered as a free fix at any Hyundai dealership (TSB 14-AT-006-1)

This is a mail-in service. Send us your TCU and we'll tune and return it ready to install.
