fuel pump priming
fuel pump priming time
Specifies the fuel pump prime time in seconds used by the system when you power on the MaxxECU, default is 3 seconds.
pre start fuel prime pulse
Enable prime pulse
Activates extra fuel pulse.
•Disabled - No extra prime pulse.
•enabled, on first trigger signal - Activates an extra fuel prime pulse when the first trigger signal is detected.
•enabled, on sync - Activates an extra fuel prime pulse when the trigger system is synced.
manual prime
Manual Prime allows controlled injector pulsing at zero RPM to pre-fuel the engine and pre-charge the intake ports, improving starting of large or high-compression race engines (e.g. drag racing applications).
enable manual priming
When enabled, and throttle position exceeds 95% (for example via a double throttle press), the ECU activates the fuel pump and delivers a predefined number of injector pulses after a configurable delay. This primes the intake ports with fuel before cranking, improving start reliability under extreme conditions.
run pump before prime
Run Pump Before Prime activates the fuel pump for a defined time before the Manual Prime injector pulses are delivered, ensuring stable fuel pressure is established prior to pre-fueling the engine. Specified in seconds.
