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 (47 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 #1 (Master Reference)

Mechanism: Bypass Screws

Fuel Pump Pressure & 5-Min Hold Test

EFI Pressure Rail

Running Fuel Pressure

47 PSI(3.24 bar)

OEM Running Spec

47 PSI (±3 PSI)

PASS: WITHIN OEM RUNNING SPEC

Fuel pump delivery pressure is 47 PSI (Factory spec: 47 PSI ± 3 PSI / 3.24 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

12.0 - 12.8 Ω at 20°C (Showerhead Secondary Injectors)

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

41 mm

Operating Temp

80°C (176°F)

Induction Type

Twin-Injector EFI with YCC-T Electronic Fly-by-Wire

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

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 take-off nipples on intake spigots under rubber heat shields. 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 #1 (Master Reference). Adjust Center balance screw (pairs 1-2 to 3-4), then #2 and #4 individual sync screws 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.

Mechanical Engineering Status:RECALL 15V-176 DEFECT LOCUS

CRITICAL RECALL DEFECT: The original factory stopper arm was stamped with an acute sharp internal notch at the bend. Under rapid gear shifts, cyclic fatigue caused catastrophic fracture at the notch. The countermeasure part features an engineered smooth radial bend that distributes stress evenly.
