First of all, make sure you fill-up using the correct octane fuel that you want the tuning to be done for.  If you aren't sure which octane to use, follow the factory manufacturer's recommendation which you should be able to find in your Owner's Manual.  Sometimes additional preparation is needed before tuning your vehicle.

Chip Socket/Adapter

Required on some vehicles built before 1995.

Some factory engine control modules (ECM) were not designed to be reprogrammable. In this case, we can modify the ECM's circuit board to accept a new chip.

Wideband Oxygen Sensor

Typically, the factory EFI uses what is called a narrowband or lambda (λ) oxygen sensor. This is only accurate for measuring fuel mixtures close to the stoichiometric fuel ratio (λ = 14.7:1). A wideband sensor is able to accurately measure a much wider range of fuel mixtures (9:1 to 22:1).

For precise tuning, we require the use of a wideband oxygen sensor to accurately measure the engine's air to fuel ratio. Usually we are able to either install the sensor in place of the narrowband sensor or we can attach a tailpipe extension.

Exhaust Gas Temperature (EGT) Sensor

Required for Power Tuning on Turbocharged Vehicles

An EGT measures the temperature of exhaust gas exiting the engine. This is another useful indicator of the engine's operating conditions and is necessary to prevent dangerous conditions which could cause engine damage.

Most vehicles will require installation of a threaded (1/8" NPT) adapter in the exhaust system. We prefer that you remove the exhaust component and bring it to us for installation prior to tuning.

Subaru EJ22T Hybrid Build | REVTRONIX

To continue further research and development on the EJ22T ECU, we picked up a project 1992 Legacy SS with a rod knock due to loss of pressure. The thrust bearing had also worn down so much that all the crank counterthrows had made contact with the block. Upon tear-down we discovered a munched rod bearing and badly pitted main bearings.

Power | REVTRONIX

We'll tune the full throttle performance of your car to achieve maximum reliable power. Measurements are taken before and after tuning so you can immediately see the results. We tune the fuel and spark maps to achieve a fast and reliable state of tune. Power and torque will increase once control of the engine is optimized. Boost can be increased for significant power gains.
