ThunderMax® EFI with Integral AutoTune
Tired of popping, spitting, backfiring, hard starts, hot running, or poor fuel mileage? This stand-alone performance ECM replaces the factory module (not an add-on box or signal modifier) to give you real control of your EFI tuning—without needing a dyno or advanced computer skills. Install it in place of the stock ECM, plug into the existing harness, replace the oxygen sensors, load the correct basemap, and ride.
Using proprietary closed-loop AutoTune technology and wide-band oxygen sensors, the system continuously monitors air/fuel ratio and automatically adjusts injector pulse width to hit your AFR targets across changing temperatures, elevations, and riding conditions. With hundreds of downloadable basemaps covering popular engine and aftermarket combinations, setup is fast—then AutoTune keeps optimizing every time you ride for smoother throttle response, improved rideability, and stronger overall performance.
For riders who want more control, the tuning software allows you to adjust and monitor virtually every parameter, including idle, rev limit, speedometer calibration, fueling, and ignition timing—plus live monitoring, recording, and diagnostic tools.
Features Include:
- Closed-loop, self-adjusting AutoTune with wide-band O2 sensors
- Adjustable AFR/RPM targets, idle speed, rev limit, and warm-up settings
- Adjustable ignition timing (spark) maps and startup fuel settings
- Decel pop control, accel pump simulation, injector size compensation
- Speedometer calibration and engine temperature alarm
- Read/clear diagnostic codes, running statistics, datalogs, and map analysis
- Live tuning, live monitoring, and live recording via USB
- Supports popular exhaust systems and performance upgrades; turbo/nitrous/boost compatible on select applications
- Free online software/firmware/map updates, tech support, and a 3-year warranty
- Engineered and made in the USA
System Includes:
- Performance ECM with integral AutoTune module
- Two (2) wide-band Bosch 5-wire oxygen sensors (18mm) with AutoTune harness*
- USB communication cable
- Tuning software (available online) and quick-start/manual resources
* Requires 18mm oxygen sensor bungs or an exhaust system equipped with 18mm bungs; some aftermarket systems may require bung modification/relocation.
