FSM Induction CalibrationInline-4 (4 Throttle Bores)

Fuel Delivery, Throttle Body Synchronization & Manometer Balancer

Factory intake depression specifications (220 mmHg), electronic fuel pump pressure testing (50 PSI), injector resistance, and interactive multi-column manometer balancing.

Warm Idle: 1,200 - 1,300 RPM

Quick Workshop Diagnostic Presets

Simulate Throttle Linkage Asymmetry, Hunting Idle, or Intake Boot Vacuum Leaks

OPTIMAL SYNCHRONIZATION: BALANCED (Δ ≤ 10 mmHg)

Diagnostics:Max Differential: Δ 0 mmHg (Factory Max Tolerance: ≤ 10 mmHg)

All 4 throttle plates pull uniform intake depression within factory engineering tolerance (≤ 10 mmHg / 1.33 kPa). Delivers immediate linear throttle pickup, silky smooth idle, uniform cylinder torque pulses, and balanced exhaust temperatures.

Workshop Multi-Column Fluid Manometer

Damped intake depression columns. Target spec: 220 mmHg (±10 mmHg) at warm idle (1,200 - 1,300 RPM).

Reference: Cylinder #1 (Master Reference)

Mechanism: Bypass Screws

Vacuum Take-Off Ports: 5mm vacuum take-off nipples on intake insulators capped with rubber plugs

Damping Protocol: Restrictor valves must be adjusted until columns oscillate no more than ±5 mmHg per intake stroke.

Fuel Pump Pressure & 5-Min Hold Test

EFI Pressure Rail

Running Fuel Pressure

50 PSI(3.45 bar)

OEM Running Spec

50 PSI (±3 PSI)

PASS: WITHIN OEM RUNNING SPEC

Fuel pump delivery pressure is 50 PSI (Factory spec: 50 PSI ± 3 PSI / 3.45 bar). High-pressure regulator and pump rotor operating within factory design threshold.

Connect mechanical gauge to the quick-disconnect fuel rail fitting using an OEM banjo or T-adapter.

Fuel Injector Resistance & Induction Specs

Multimeter Bench Check

OEM Injector Solenoid Resistance

11.6 - 12.4 Ω at 20°C (Dual-Stage Fuel Injection DSFI)

Measure across injector 2-pin harness socket with ignition OFF. Internal coil resistance increases by ~0.4% per °C rise above 20°C (68°F). Replace injector if resistance reads open (> 100 kΩ) or shorted (< 2 Ω).

Bore Diameter

40 mm

Operating Temp

80°C (176°F)

Induction Type

Dual-Stage Electronic Fuel Injection (DSFI) with 12-Hole Injectors

Injector O-rings must be lubricated with a light coat of clean engine oil before seating into fuel rail.

4-Step Throttle Body Synchronization Protocol

Official workshop manual step-by-step checklist. Mark each step as you complete it on the workbench.

0 of 4 Steps Complete

1CLICK TO MARK DONE

Engine Pre-Flight Conditioning

Check and adjust valve clearances to spec before attempting sync. Ensure air filter is clean, spark plugs are fresh, and engine is fully warmed to operating temperature (80°C–90°C).

2CLICK TO MARK DONE

Manometer Connection & Damping

Connect 4-column liquid or digital manometer hoses to 5mm vacuum take-off nipples on intake insulators capped with rubber plugs. Adjust in-line hose restrictor valves to dampen rapid intake pulsation until fluid columns stabilize.

3CLICK TO MARK DONE

Balance Screw Calibration

With engine idling at 1,200 - 1,300 RPM, identify Cylinder #1 (Master Reference). Adjust Center balance screw (pairs 1-2 with 3-4), then individual balance screws on #2 and #4 until all cylinder columns are within 10 mmHg (1.33 kPa) of the master reference.

4CLICK TO MARK DONE

Throttle Blip & Locknut Verification

Blip throttle to 3,000 RPM 2–3 times and verify columns return evenly to idle balance. Tighten any balance screw locknuts securely, re-install rubber vacuum sealing caps, and verify idle speed.

FACTORY WORKSHOP SPECIFICATION:

Critical Recall Safety Countermeasure

CRITICAL WORKSHOP PROCEDURE:

CRITICAL RECALL COUNTERMEASURE (Recall 24V-113 / Bulletins KP9 & KQ0). Original low-density resin impellers absorbed solvent from automotive fuels, swelling and binding against the pump casing to cause sudden engine shutdown while riding. Replacement module features reinforced high-density resin impeller.
