E85 hands out power like it's going out of fashion, but only if your car knows exactly what's in the tank. A flex fuel sensor reads ethanol content in real time and feeds it to your ECU, letting the tune adjust fuelling and timing automatically between pump 98 and E85.
At Pro Speed Racing, we help enthusiasts find flex fuel sensors and complete plug-and-play kits to suit popular turbocharged platforms and standalone ECU setups. That means one car, multiple fuels, zero guesswork at the bowser.
We do not store every sensor and kit on hand, but our sourcing network gives you access to quality flex fuel hardware direct from trusted suppliers. If you need a specific sensor, fitting size or platform kit, Pro Speed Racing can help source the right gear.

Ethanol content in Australia is famously variable, and that's exactly why the sensor matters. E85 from the pump can swing meaningfully batch to batch, and a flex tune reading real content keeps timing and fuelling safe no matter what actually came out of the hose.
Sensor quality is non-negotiable on a flex build because the whole tune trusts its output. Genuine sensors with proper fittings deliver stable, accurate readings for years, which is cheap insurance on an engine running ethanol-fed boost.
