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.
| 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.
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.
Without a proper FlexFuel tune + sensor, running E85 blends can cause detonation and severe engine damage.
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.
✓ Works on Automatic or DCT transmissions
✓ Works on ZF8 automatic transmission only (manual version available separately)
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.
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.
No – these kits are for automatic transmission cars only.
