Bootmod3 FlexFuel Kit Basic – Toyota GR Supra A90/A91 / BMW Z4 G29

OVERVIEW

The bootmod3 FlexFuel Kit – Basic is the frequently requested, more economical alternative to the bootmod3 High Flow kit. It is an engine bay mounted kit that uses specialty fittings to plug and play with the OEM fuel lines, rather than requiring fabricated lines and spliced wiring.

Install the kit, flash a flex fuel enabled bootmod3 OTS MultiMap or custom map, and the alcohol/gasoline blend percentage in your tank is handled automatically — no re-flashing between fills. The kit installs in minutes at home rather than taking hours on a lift, and is fully reversible: it can be removed and the car returned to stock without a trace.

SPECS

• This kit is for engine bay installation.
• Two specialty 5/16" plug-and-play flex fuel sensor fittings that adapt to the OEM fuel lines
• CANBUS-enabled Ethanol Content Analyzer (ECA) that integrates with bootmod3 CustomROM for a complete, seamless FlexFuel conversion
• Works with bootmod3 flex fuel enabled OTS MultiMaps and with custom tunes from your bootmod3 tuner of choice
• Power/CANBus harness is 100% plug and play with the BMW / Toyota Supra MKV Body Domain Controller (BDC) connector — no cutting, splicing or pinning of OEM wiring
• Fully reversible and removable, back to stock without a trace, in minutes
• Uses a Continental flex fuel sensor
