CARB Compliance / Exemption Warning: If you live in California and your application for this product is not CARB Compliant / Exempt, then you cannot purchase it for public highway or street use (in that case it could only be used for formally sanctioned race use on a racing vehicle that may never be used on a public highway or street). If your application is not CARB Compliant / Exempt and you're shipping to California, our system will let you know on the final checkout page.

If you live outside the United States, we cannot ship this product to you. This is because we are a USA Hondata dealer, and we can only sell to USA customers.

The Hondata injector driver allows either the use of high or low impedance injectors without a resistor box either as injectors slaved to the ECU injector output or as staged injectors. Why not just use the stock ECU to control low impedance injectors? Well, since low impedance injectors draw more current than high impedance injectors, they will eventually overheat if the injector driver output does not limit the current. The main concern is that the ECU injector driver outputs will be damaged as they are not designed for the amount of current that low impedance injectors draw.

Staged injection allows the use of primary and secondary injectors of different sizes. The primary injectors are always used, and may be stock or other injectors with a rapid opening time and good spray pattern., The secondary injectors activate based on driving conditions, and may be larger than the primary injectors. The injector sizes and dead times for each set of injectors do not need to be the same (e.g. stock 310cc injectors can be used until boost, at which point both 310cc and 1300cc injectors are used).

It also is possible to use two independent fuel systems for each set of injectors (e.g. the secondary injectors may use E85 or race gas). Staged injection requires ECU outputs. Currently this is only supported by the S300 & K-Pro, as almost all FlashPro ECUs do not have accessible outputs.

Key Features:
  • Four channel injector driver with activation input.
  • Drives both peak and hold (low impedance) and saturated (high impedance) injectors.
  • Injector current control to ensure both rapid injector operation and low injector temperature.
  • Replaces unreliable resistor boxes.
  • Housing sealed to IP65 (water resistant).
  • Activation input allows easy injector staging.
