S13 (CA18DET engine only) Stage 1 ECU upgrade chip
The S13 Stage 1 ECU upgrade chip is designed to optimise the fuelling and ignition for an S13 (CA18DET engine only) with the following modifications:
Free flow air filter
Free flow exhaust
Boost controller to achieve 15psi boost pressure
Uprated fuel pump
Super unleaded fuel (>97 RON)
Front mount intercooler
The chip removes the fuel cut and, in conjunction with the upgrades above, will allow the engine to produce around 230bhp.

The red lines show the car with a standard chip at 10psi boost pressure. One line shows the torque, the other shows the power. Peak power is 188bhp @ 5918rpm and peak torque is at 173lb ft @ 5471rpm
The blue lines show car with a Stage 1 chip at 15psi boost pressure. Again the lines show torque and power: 212bhp @ 5750rpm and 201lb ft @ 3461rpm. Notice the huge gain in torque, up 63%, in the mid range (~3500rpm) and the much lower rpm of the peak torque. Also the peak power is up 13%. The extra power and torque comes from the boost upgrade, the Stage 1 chip optimises fueling and ignition timing for this setup. You could not get this power and torque increase without an ECU chip upgrade.
