Our FuelTech ECUs are standalone engine controllers with flexible mapping, high-rate logging and CAN connectivity. They support wideband-based closed-loop fuelling, drive-by-wire control and safety limits for AFR/EGT/oil pressure—delivering steady idle, reliable starts and repeatable power for road–track builds.
Brief summary & key benefits
FuelTech ECUs deliver complete engine management in a compact package. Rich I/O, high-rate logging and flexible mapping enable data-led tuning and consistent power on road and track. CAN connectivity simplifies integration with dashes, wideband modules and data systems, while AFR/EGT/oil safeguards protect the engine under fault conditions.
Technical Basics
Controllers decode common crank/cam trigger patterns for precise timing. Typical features include wideband-driven closed-loop fuelling, drive-by-wire throttle, idle strategies, optional flex-fuel sensing and multi-table ignition/fuel maps. Output topology (low-side/high-side), coil drive type (logic or inductive) and sequential injection support must match your hardware. High-sample logging and chart-based review expose trends such as fuel-pressure drop, knock onset or thermal peaks.
Tuning suites provide live table editing, quick map switching, start and warm-up enrichments and temperature-based corrections. Deterministic behaviour depends on clean sensor power, solid grounds and proper shielding—especially on boosted or high-compression platforms where noise margins are tight.
Selection Criteria
List required I/O: injector and ignition outputs, sensors (MAP, IAT, CLT, TPS, EGT, wideband) and auxiliaries (fans, pumps, boost solenoid). Verify compatibility with crank/cam patterns (e.g., 60-2), DBW throttles and loom connectors. Forced-induction engines benefit from staged boost control, AFR/EGT-based protection and reliable fuel-pressure monitoring. Consider the software ecosystem—documentation, log viewer and dependable firmware updates.
Use cases: road–track builds target stable idle, clean signals and good cold-start; time-attack cars focus on repeatable power and heat management; drift applications benefit from quick map switching and torque shaping. With factory looms, an adapter harness eases integration; bespoke looms provide maximum robustness, shielding and strain relief for harsh duty.
Installation & Maintenance
Work on an isolated system. Keep power/ground runs short with direct battery and clean chassis grounds. Route sensor lines away from ignition/high-current paths; use shielding and twisted pairs where appropriate. After installation, verify crank/cam sync, sensor sanity and supply stability. Start with conservative limits (boost, EGT, oil pressure) and iterate using logged data; re-check grounds and fastener torque after initial heat cycles and vibration.
Maintenance tips: back up calibrations regularly, follow firmware procedures and review trends (AFR, knock, fuel pressure). Observe wideband heater guidelines and check the exhaust for leaks that could skew readings. Periodically inspect loom retention, connector seals and any signs of abrasion or heat damage.
FAQ
Q: Why choose FuelTech over an OEM ECU?
A: More tuning control, richer I/O and logging for modified engines—when installed and calibrated correctly.
Q: Do I need a wideband O₂ sensor?
A: Yes—for effective closed-loop fuelling and protective strategies.
Q: Can I reuse the factory loom?
A: An adapter harness is common; custom looms suit complex I/O and harsher environments.
Q: Which trigger patterns are supported?
A: Common patterns such as 60-2/36-1; confirm against your engine’s pickups.
Q: How long does tuning take?
A: It depends on engine spec and I/O complexity; tune progressively using logs and conservative limits.
