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).

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

48 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.

CRITICAL WORKSHOP PROCEDURE:

CRITICAL RECALL SAFETY COUNTERMEASURE (Recall 22V-061 / Service Bulletin MTB 17819). Extended 1st gear operation above 5,000 rpm causes exhaust radiant heat to melt the oil cooler outlet pipe. The heat guard installs directly between the #2/#3 header pipes and the oil lines.

CRITICAL WORKSHOP PROCEDURE:

CRITICAL RECALL INSPECTION (Recall 21V-249 / Bulletin KL9). Visually verify that the machined counterbores face OUTSIDE. The bolt head and nut MUST recess cleanly into the plate bores. If flat face is facing outside, plates were installed backwards at the factory and will bind and fracture.

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.
