Why Excess?

Tight Testing Controls

All Excess Injectors are tested on our custom built test bench to J1832 standards.

  • Pressure is electronically controlled at 3 bar
  • Temperature is controlled at 21°C
  • Votage is controlled at 14V
Because the testing parameters are so tightly controlled we get the same results everytime we test them.

Tightly Grouped Sets

We don't just dynamically flow test injectors we also measure the dead time of each injector. Every set is:
  • Dynamically flow matched within 1%
  • Deadtime matched within 2%

Exact Match Data

Every set you buy comes with tuning data exactly matched to your set. It is based on how that set performed on the test bench. Saves dyno time tuning injectors and you get a perfect result every time.
  • data formatted for 11 different ECU/software types
  • no two tune files are the same
  • tuning data is matched exactly to your set

How many points are tested?

  • over 6,500 flow points are tested and recorded on every injector.
  • over 265,000 measurements for flow, pressure, voltage etc are recorded for every injector
  • tuning data specific to your set is available for download to make an easy tune

Lifetime Guarantee

If an injector has an issue not related to contamination or damage from external forces we simply replace the injector for you. It's that easy.
We know exactly how your injector set should flow and what the deadtimes are because we store that information on the cloud server. We just replace the injector with another one that matches your injector set exactly.
