Engine Electrical — Tuners, Sensors & Wiring
Modern European performance is won in the electronics. This collection brings together performance programmers and tuners, throttle controllers, performance monitors, oxygen sensors, wiring harnesses, connectors, crank triggers and fuel-injection control modules.
A handheld tuner or in-line module is the highest value-per-dollar modification on most turbocharged platforms — B58, S55, EA888 and AMG turbo cars all respond strongly to calibration alone. Throttle controllers sharpen pedal mapping without touching the ECU, and a wideband oxygen sensor is non-negotiable once you start changing hardware: tune blind and you find the limits the expensive way.
Replacing aged O2 sensors also restores fuel trim accuracy and throttle response on higher-mileage cars — worth doing before chasing phantom running issues. If you are supporting more airflow, pair electronics with an intake from our air intake systems range or hardware from forced induction, and monitor the results with a proper performance gauge.
Check each listing's application data against your engine code and model year — electrical parts are unforgiving of near-miss fitment. Order online for nationwide shipping, or have our Miami shop install and verify the setup.
