FSM Induction CalibrationInline-4 (4 Throttle Bores)

Fuel Delivery, Throttle Body Synchronization & Manometer Balancer

Factory intake depression specifications (225 mmHg), electronic fuel pump pressure testing (43.5 PSI), injector resistance, and interactive multi-column manometer balancing.

Warm Idle: 1,250 - 1,350 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: 225 mmHg (±10 mmHg) at warm idle (1,250 - 1,350 RPM).

Reference: Cylinder #2 (Master Reference)

Mechanism: Bypass Screws

Vacuum Take-Off Ports: Vacuum hoses connecting intake spigots to clean-air switch valve (clamp hoses during sync)

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

Running Fuel Pressure

43.5 PSI(3.00 bar)

OEM Running Spec

43.5 PSI (±3 PSI)

PASS: WITHIN OEM RUNNING SPEC

Fuel pump delivery pressure is 43.5 PSI (Factory spec: 43.5 PSI ± 3 PSI / 3 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

11.7 - 12.3 Ω at 20°C (Dual Injectors: Fine-Atomizing Showerhead)

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

Operating Temp

80°C (176°F)

Induction Type

DFI Digital Fuel Injection with Sub-Throttle Valves

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

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 Vacuum hoses connecting intake spigots to clean-air switch valve (clamp hoses during sync). 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 1,250 - 1,350 RPM, identify Cylinder #2 (Master Reference). Adjust Center balance screw (pairs 1-2 to 3-4), then individual screws for #1 and #3/#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 REPLACEMENT (Recall 16V-102 / Bulletin MC16-03). Original bolts overtightened at assembly fractured, causing the steering damper bracket to detach from the frame. Replace both bolts: finger-tighten both, torque right bolt to 8.0 N·m, torque left bolt to 8.0 N·m, then re-torque right bolt to 8.0 N·m.
