One of the best upgrades I’ve done to my Supra. The kit feels extremely well thought out, especially the custom hoses and true plug-and-play design. No cutting or wiring headaches at all. Ethanol content updates instantly in the app and tuning adjustments feel smooth and safe.

Bought this for my MKV Supra and couldn’t be happier. The quality of the harness and fittings exceeded expectations, and setup took less than an hour.
The sensor quality is top-notch and the CAN integration works perfectly with MHD. Car pulls harder on E blends while maintaining stock-like drivability.
Very impressed by the attention to detail in this kit. The installation instructions were easy to follow, and the hardware quality is excellent. My Supra now handles ethanol blends perfectly and the car runs smoother than expected. Definitely worth the investment for serious tuning setups.
Great product for anyone running E85 on a G-series BMW or Supra. The analyzer communicates perfectly with the DME and ethanol content updates quickly. Car starts, idles, and drives beautifully on mixed blends. Feels like a factory-calibrated solution.
I’ve tried other ethanol sensor setups before, and this is by far the cleanest solution. True plug-and-play installation with quality connectors and no guesswork. Integration with MHD is seamless and the tuning flexibility is incredible. Highly satisfied with the purchase.
