Im looking for injectors for my turbo setup and i ran into a choice between Low impidace and High impidance. Whats The Difference? Thanks

The difference lies in the way the injectors operate and is directly affected by the type of injector driver your ECU has.

A high impedance injector is typically referred to as a "Saturated" injector that only requires around 1 amp from the ECU to work properly. This means very little heat is transferred through the computer itslef.

A low impedance injector is typically referred to as a "Peak and Hold" injector that can require anywhere from 4-6 amps or more from the ECU to work correctly and will need an ECU that is capable of handling a lot more heat.

99% of factory ECU's are set up as "saturated" or high impedance types and cannot work with P&H injector types. However if you are lucky enough to have an ecu with P&H capability then you can run either injector type without any issues.

It is important to check the resistance of your current injectors and make sure the new ones have a similar value to avoid damaging your computer.

Good luck and hope that helps.
