Fuel Delivery, Throttle Body Synchronization & Manometer Balancer

Factory intake depression specifications (240 mmHg), electronic fuel pump pressure testing (43.5 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 ≤ 15 mmHg)

Diagnostics:Max Differential: Δ 0 mmHg (Factory Max Tolerance: ≤ 15 mmHg)

All 2 throttle plates pull uniform intake depression within factory engineering tolerance (≤ 15 mmHg / 2.00 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: 240 mmHg (±15 mmHg) at warm idle (1,200 - 1,300 RPM).

Reference: Horizontal Cylinder (Front Master)

Mechanism: Bypass Screws

Vacuum Take-Off Ports: Intake manifold vacuum takeoff ports with brass screw 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

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

11.9 - 12.5 Ω at 20°C

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

50 mm

Operating Temp

80°C (176°F)

Induction Type

Electronic Fuel Injection with 50mm/53mm Full Ride-by-Wire Throttle Bodies

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

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 2-column liquid or digital manometer hoses to Intake manifold vacuum takeoff ports with brass screw 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 Horizontal Cylinder (Front Master). Adjust Vertical cylinder balance screw with air bleed bypass screws on each runner until all cylinder columns are within 15 mmHg (2.00 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.
