AiM Sports KA 50 psi Boost/Vacuum (Absolute Pressure) Sensor This "absolute pressure" sensor is ideal for measuring vapor (gas) pressures, such as intake boost and crankcase pressure. The 50 psi pressure range is based on perfect vacuum (i.e., from 15 psi below atmospheric pressure to 35 psi above). This sensor is marked "0-50psiA" to differentiate it from the standard 0-50 psi sensor (marked "0-50psiSG"), which does not measure vacuum. KA pressure sensors are more robust than VDO-style pressure sensors, but they should still be isolated from engine heat and vibration whenever possible. Features 1/8" NPT male threads.Kart  The AiM KA 50 is compatible with these AiM products: MyChron5 MXL MXL 2 MXG MXS MXM EVO3 EVO4

AiM Magnetic Pedal Position Sensor For MyChron Dashes Magnetic accelerator- and brake-pedal position sensors are crucial devices for kart drivers and teams. They provide precise indications of timing and intensity of braking and acceleration. This helps the team to understand whether the driver has accelerated and braked at the right moments, with the correct pedal strength, across multiple laps and overlaid with other critical data. These are very important factors in evaluating driver behavior and improving his/her performance. Data can be logged by your MyChron dash connected to a MyChron Expansion, then analyzed on your PC post-race. Made from anodized aluminum, these sensors are very robust and water-resistant. Calibration is immediate: once installed, connect the sensors to your MyChron Expansion and set pedal positions (high position and zero position). After that, the sensor will start transmitting accelerator or brake pedal data.

AiM Kart Racing Steering Angle Sensor Measure and log your kart driver's steering input with the AiM Steering Angle Sensor. Includes a rotary potentiometer with a male 4-pin 719-style connector, two toothed pulleys, one toothed belt, and one sensor mounting bracket. The steering shaft pulley is designed to fit a 7/8"-diameter shaft. (Smaller shafts will need to add a bushing to fit the pulley.) This sensor is designed to measure up to five complete turns of the steering column. This sensor requires the addition of an Expansion Box or eBox when used with MyChron3 Extreme, MyChron4, and MyChron5 kart dash loggers. If your steering column is larger than 7/8", consider using the AiM String Pot Steering Angle Sensor (Part No. AIM-MC-280) instead. The String Pot can work with any diameter steering shaft.

AiM Sports MyChron 5S 2T Data acquisition for karts enters a totally new dimension: MyChron 5S 2T. Besides sampling all your kart data, MyChron5S 2T features all the advantages of GPS timing and tracking, dual-temperature inputs, plus a lot of new functions designed to provide more complete and reliable information both during and after each race: Lap and split times Speed RPM Combine EGT with either CHT or H2O temps Track Position Acceleration Much more! MyChron5S 2T has been designed to provide both basic info (for new racers) and the most sophisticated data to karting professionals. Fully configurable layout lets you customize the data, color, LED indicators, etc. to suit your individual needs. The MyChron 5S 2T comes with a Y-Cable for temperature sensors, an EGT thermocouple, and your choice of either a CHT (cylinder head temp) or H2O (water jacket) thermocouple. Using a two-satellite sensor, the MyChron 5S 2T provides super-accurate GPS data for lap/split times, position, speed, etc. We have a huge track database for easy download of detailed track info. For ten years, the MyChron4 was the benchmark gauge in karting data acquisition. AiM re-establishes the benchmark with the MyChron 5S 2T, a leap ahead of the 4 (and all its imitators). At the same time, the MyChron5 2T is fully compatible with all MyChron4 peripherals, as well as a Lambda controller, Data Hub, MyChron Expansion, and SmartyCam. FEATURES: Automatic Start Rechargeable Li-Ion battery lasts up to 10 hours 1 MB memory for over 3 hours of data logging Two Temperature channels Seven fully-configurable LEDs (alarm, shift, etc.) LCD screen with configurable color Wireless data download via secure Wi-Fi connection Intuitive menu design for easy configuration Call Competition Karting's data acquisition experts with any questions you have about the incredible MyChron5S 2T from AiM!

AiM MyChron Expansion The AiM MyChron Expansion is an add-on for the MyChron4 or MyChron5 Kart Racing Data Logger Dash. It plugs into the CAN expansion port on your MyChron dash to expand its capabilities. The Expansion has a single CAN expansion port plus four additional sensor inputs. All four inputs can accept common karting sensors (brake/throttle pedal position, temperature, steering angle, etc.). One of the four inputs can accept a speed sensor instead. Requires an external 12-volt power source such as your kart's battery. The MyChron Expansion channel multiplier improves MyChron5 and MyChron5 2T (and also MyChron4 and MyChron4 2T) performance, thanks to four additional channels and a further CAN bus connector. Through this last connector, the systems can be connected to LCU-One Lambda controller and SmartyCam HD (and to GPS and Data key for MyChron4 systems). Thanks to its specific wirings, MyChron Expansion powers the systems and their peripherals with an external battery, avoiding internal battery consumption. All channels are easily configurable as analog through the system menu to sample data coming from: Exhaust gas valve position sensor (very important to understand at which RPM value the exhaust port opens) Wheel speed sensor: the first input on the left can be configured also as digital input No contact brake pedal position sensor No contact throttle pedal position sensor Brake pressure sensor Water temperature or cylinder head temperature (PT100 thermo-resistor only) Steering angle potentiometer (to highlight over/under steering situations) Brake pedal potentiometer Throttle pedal potentiometer MyChron Expansion is a complete, value-for-money instrument for professional kart analysis. Call us with any questions you have about the MyChron Expansion from AiM Sports!
