[S14] De verschillende stages uitgelegd

Recommended Posts

The S14/S14a Stage 1 ECU upgrade chip is designed to optimise the fuelling and ignition for an S14 with the following modifications:

Free flow air filter

Free flow exhaust

Uprated fuel pump

Boost controller to achieve 15psi boost pressure

Super unleaded fuel (>97 RON)

The chip removes the fuel cut and 250km/h (155mph) speed limit. It smooths out power delivery and should improve fuel economy when cruising.

The graph below is a power run on an S14a with the modifications listed above

285bhp and 300ft.lbs torque!

 

 

The stage 2 ECU upgrade chip is designed to optimise the fuelling and ignition for an S14 with the following modifications:

Free flow air filter

Free flow exhaust

Uprated fuel pump

Boost controller to acheive 17psi / 1.2 bar boost pressure

Front mount intercooler

Nismo 555cc injectors (Nismo injectors are essential - other brands will not work correctly)

Super unleaded fuel (>97 RON)

The ECU upgrade removes the fuel cut and 250km/h (155mph) speed limit. It smooths out power delivery and should improve fuel economy when cruising.

The peak power measured here was 300bhp and a 305ft/lb of torque. Obviously results will vary depending on engine condition, rolling road, air temperature and so on.

 

 

 

The stage 3 ECU upgrade chip is designed to optimise the fuelling and ignition for an S14 with the following modifications:

Free flow air filter

Free flow exhaust

Tubular manifold

Uprated fuel pump

Boost controller to acheive 17-20psi / 1.2-1.4 bar boost pressure

Front mount intercooler

Nismo 555cc injectors (Nismo injectors are essential - other brands will not work correctly)

Z32 AFM

GT28RS turbo

Super unleaded fuel (>97 RON)

The ECU upgrade removes the fuel cut and 250km/h (155mph) speed limit. It smoothes out power delivery and should improve fuel economy when cruising.
