MHD FlexFuel Kit – F-Series / G-Series & Toyota Supra (Automatic Transmission)

Plug & Play E85 FlexFuel Kit with CAN Ethanol Content Analyzer (ECA) – Works with MHD Super License and EcuTek tunes. Compare F-Series (B46/B48/B58/N55/S55) and G-Series/Supra (B48/B58/S58) versions.

Quick Comparison

Feature F-Series Kit G-Series / Supra Kit
Engines Supported B46 / B48 / B58 / N55 / S55 B48 / B58 / S58
Transmission Automatic / DCT Automatic (ZF8)
Key Difference in Box Standard PR360 fittings PR360 fittings + Custom Dorch Engineering hoses

Both kits share the same core features: 100% plug-and-play, no splicing, bench-tested, full CAN integration for ethanol % and fuel temp.

What is an ECA (Ethanol Content Analyzer)?

The CAN Ethanol Content Analyzer (ECA) reads real-time ethanol percentage directly from the Continental E85 sensor, converts it to CAN bus data, and sends accurate ethanol content and fuel temperature to the DME (engine computer). This allows your MHD or EcuTek tune to safely run any blend from E0 to E100+ on the fly.

E85 vs FlexFuel – What's the Difference?

  • E85 – A high-octane fuel blend (typically 51–85% ethanol)
  • FlexFuel Feature – The ability of the ECU tune to automatically adjust timing, fueling, and boost based on the actual ethanol content detected by the ECA

Without a proper FlexFuel tune + sensor, running E85 blends can cause detonation and severe engine damage.

What is This Kit?

This kit enables a FlexFuel feature for MHD and EcuTek tuned cars. Without the correct tune (for the E85 blend used) the engine does not work right and may get damaged.

Frequently Asked Questions

Is it really plug-and-play?

Yes. All connectors are OEM-style. You only remove the factory fuel line, click in the sensor with PR360 fittings, and plug the harness into the ECU area.

What's the main difference between F-Series and G-Series kits?

The G-Series kit includes custom Dorch Engineering hoses for enhanced compatibility, and supports newer S58 engines. F-Series covers older N55/S55 and DCT transmissions.

Will this work on manual transmission cars?

No – these kits are for automatic transmission cars only.
