*Global B ECUs may require extra tuning on a case-by-case basis as we learn more about new models. We do not accept returns due to tuning difficulties, but we’re happy to assist with any technical inquiries.
Application
- Maximum Rail Pressure: 193 bar / 2,800 psi
- Fuel Compatibility: All known fuels, all ethanol blends
- Electric Connector: Bosch EV1
- Driver Profile: XDI, tuning changes needed
- Static Flow Rate: 30.1 g/sec (2600 cc/min @ 100 bar)
- Tuning Support: Standalone, HPT, MoTeC
Injector Data
Flow Rates
- 2600 cc/min at 100 bar
- 3700 cc/min at 200 bar
Increased Flow
- 96% more flow than production LT1/L86 injectors (15.3 g/sec)
- 70% more flow than production LT4 injectors (17.7 g/sec)
- Performance: Rock-solid, perfectly linear
- Fitment: 100% drop-in with OEM spray pattern
- Tuning: Custom tuning required, with only one ECU value change
Cold Start & Idle: Stock-like cold start and idle not expected, especially on pump gas.
Note: Due to the LT4 +70% Injectors large size, these injectors may not deliver stock-like drivability, especially on pump gas. Manual transmission cars may experience pressure overshoots after shifting, potentially causing misfires. Reducing pressure may be necessary.
Injector Testing and Documentation: Each XDI injector set is rigorously tested and matched at three critical operating points, with full documentation provided:
- Idle Stability: 0.8 ms at 20 bar
- Static Flow Reference: 10 ms at 100 bar
- WOT Performance and Stability: 6 ms at 200 bar
