AEM Product Lines We Repair
Our engineers are trained on the full AEM product range. Below are the major product families we service.
AEM Infinity EMS
Programmable engine management systems for standalone ECU applications. Common issues include sensor signal dropout, fuel injector driver failures, ignition coil pack interface faults, and firmware corruption from improper flashing. Synchronics performs full ECU diagnostics and reprogram to OEM specification.
AEM Programmable Fuel Injection
Standalone fuel control modules for carbureted and traditional fuel-injected engines. Frequent faults include injector output short circuits, supply voltage regulation failures, and sensor input buffer issues. We restore fuel delivery precision through component-level repair.
AEM Data Logger & Dash Display
Real-time engine parameter acquisition and telemetry modules. Common failures: SD card interface errors, CAN bus communication faults, temperature sensor input drift, and display driver failures. Synchronics restores data integrity and sensor accuracy.
AEM O2 Sensor Controllers
Wideband oxygen sensor interfaces and closed-loop fuel feedback modules. Typical issues: input amplifier saturation, reference voltage instability, exhaust heater relay failures, and sensor connector corrosion damage. Recalibration and component replacement restores feedback accuracy.
AEM Boost Control Solenoids
Programmable boost pressure regulation modules for turbocharged and supercharged engines. Common faults: solenoid coil burnout, PWM driver transistor failure, boost sensor signal loss, and vacuum line degradation. Synchronics performs electromagnetic testing and solenoid replacement.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common AEM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AEM equipment arriving at our workshop.
- ✓AEM ECU no power or intermittent startup — Main power relay failure, corroded battery connector on ECU harness, or internal 5V regulator circuit damage from voltage spike. Common in motorsports vehicles with poor grounding or aftermarket alternators.
- ✓Fuel injector output short or open circuit — Injector driver MOSFET failure due to inductive kick on solenoid shutdown, water ingress into ECU connector causing bridging, or failed gate drive circuit. Motorsports ECUs run at high current switching frequencies—drivers fail faster under stress.
- ✓Sensor input noise or dropout during acceleration — Damaged shielded cable between sensor and ECU, EMI from ignition system or engine harness interference, or failed input buffer amplifier in ECU. High-performance ignition systems generate significant electrical noise.
- ✓CAN bus communication failure with dash or data logger — CAN transceiver chip failure, termination resistor damage, or software firmware mismatch between ECU and display modules. Common after firmware updates without proper calibration reset.
- ✓Ignition coil driver open or weak spark — Ignition output transistor failure from detonation events, bad ground on coil connector, or internal capacitor degradation in ignition timing circuit. High RPM motorsports engines stress coil drivers.
- ✓Wideband oxygen sensor signal stuck or ratiometric error — Sensor heater circuit failure (broken heater wire in sensor or driver MOSFET short), stale calibration constants in ECU EEPROM, or sensor connector pin corrosion. Thermal cycling in engine bay accelerates degradation.

Frequently Asked Questions — AEM Repairs
Do you repair AEM equipment anywhere in India?+
Yes. Synchronics repairs AEM ECUs, fuel injection controllers, data loggers, and sensor modules across India. We offer PAN India pickup service from Mumbai, Pune, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, and all major cities. Repairs happen at our Vadodara, Gujarat facility with turnaround typically 7–10 working days.
Can Synchronics reprogram AEM Infinity ECU firmware after component repair?+
Yes. After component-level repair, we reprogram AEM Infinity ECU firmware using OEM flash tools. We restore your original tune file or baseline configuration. If you provide your tuning file, we flash it back to the ECU. If lost, we can load factory basemap pending your engine specifications.
What happens if my AEM ECU won't communicate with the tuning software?+
Synchronics diagnoses USB or CAN communication faults using bench isolation testing. We check the serial bootloader circuit, test USB transceiver chips, and verify FTDI interface functionality. If the ECU harness is the issue, we trace and repair broken signal lines. Communication typically restored within 48 hours of diagnosis.
Do you test AEM fuel injector outputs under actual load?+
Yes. After repair, we bench test each injector output stage with simulated 4–8A solenoid loads and measure switching waveforms. We verify rise time, switching frequency, and peak current delivery match AEM specifications. Testing confirms driver durability before your ECU returns to the dyno.
Can Synchronics fix AEM wideband sensor signal errors or calibration drift?+
Yes. We test the wideband controller's heater circuit, signal conditioning amplifier, and sensor interface. If the sensor itself is faulty, we recommend replacement (Synchronics stocks AEM UEGO sensors). We recalibrate AFR lookup tables in the ECU after sensor installation to ensure accurate closed-loop fueling across your rpm range.
How do I send my AEM unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a AEM drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on AEM repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your AEM unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
