AMMP3CUSTOM Altmann. AMM-P3 ignition module, single fire

This Altmann AMM-P3 single fire ignition module is a game-changer for anyone converting a fuel-injected Harley to a carburetor setup. It fits all 1999 to 2017 Twin Cam models and 2004 to 2022 Sportsters, and it even works with fuel-injected Evos and 2008 to 2010 Buell XB models with crank sensors. Setup is incredibly straightforward—easier than old-school points—using three control knobs to dial in your maximum advance, curves, and rev-limiter settings up to 6500 RPM. It’s compact, measuring just 6x7x3cm, and integrates with your stock crank sensor and coil. On stock bikes, you can keep the original ECU to maintain the immobilizer and speedometer functions. Whether you want a smooth 900 RPM idle or a classic 350 RPM lope, this unit delivers dependable, high-performance timing without needing a computer.
