Why Choose the GT320/350 Steering Wheel
The Aim Formula Steering Wheel GT320/GT350 is used for GT and closed cockpit cars where space is at a premium. The internal data logger is fully configurable and suitable for many different motorsports. It has been designed to acquire and display data coming from the ECU with over 1,000 fully compatible ECU protocols.
Our Formula wheels come in a range of sizes (270, 280, GT320 & GT350). The difference between the Formula Steering Wheel 4 GT320 and the GT350 is the overall size of the wheel; the Formula Steering Wheel GT350 is 30mm larger to meet every driver's requirements.
Easy Connection
Connecting the Aim Formula Steering Wheel GT320/GT350 to your ECU is simple. You can choose between an Aim Harness or craft your own harness using the existing Deutsch cable connected to the module.
You can sample dozens of channels straight from the vehicle ECU. This is usually the quickest and easiest setup, needing only a cable connection to the ECU instead of multiple connections and analogue sensors.
The sampled data will depend on your actual ECU, but typically includes RPM, engine load, throttle position (TPS), oil, air, water temperature, oil pressure, battery voltage, speed, gear and lambda value (air/fuel ratio). The list of available ECU drivers is constantly updated and upgraded, and includes over 1,000 different ECUs.
With the CAN Output, you can also send messages directly to an existing CAN network to improve the range of vehicle control possibilities.
