Pro R Apex Harness

Optional wiring that adds every input the Axiom ECU can use on the Pro R: boost control, AFR, flex fuel, oil pressure and fuel pressure.
The Axiom ECU works on your Pro R with the stock wiring. Apex is the complete harness. It has everything the Axiom Core harness has, plus oil pressure and fuel pressure. With the matching sensors connected, the ECU can control boost, read AFR, run flex fuel and watch oil pressure and fuel pressure.

Included inputs:

• Boost control
• AFR
• Flex fuel
• Oil pressure
• Fuel pressure

Tuners, you need this harness if you want to:

• Build safety features, such as cutting power or limiting the engine if oil pressure or fuel pressure drops out
• Tune a turbo or supercharger build with boost control
• Log AFR, oil pressure and fuel pressure while tuning
• Tune a flex fuel setup

Riders, you need this harness if you want to:

• Have the ECU protect the engine if oil pressure or fuel pressure drops
• Run a turbo or supercharger with boost control
• Watch AFR on your stock dash
• Run flex fuel and switch between pump gas and E85

You don't need it if you:

• Just want the tune on a stock Pro R
• Only want boost control, AFR and flex fuel. The Axiom Core harness covers those for less.

Note: the harness alone doesn't turn any of this on. AFR needs this harness and the Stock Dash AFR Reading entitlement. Flex fuel needs this harness, a flex fuel sensor and the Flex Fuel Control entitlement. Boost control needs this harness and the Map Sensor (Control) entitlement. Oil and fuel pressure protection need the harness and the matching sensors.
