With today’s modern control systems, a simple clean and flow static test just doesn’t cut it any more. Calibrated Success has the ability to test fuel injectors to the SAE J1832 standard and deliver calibration ready data in a useful format to the client. Dynamic flow tests are run at a wide range of pulsewidths and voltages to truly characterize the injectors’ behavior from the point of opening, through the nonlinear range, up into linear and static flow. The results allow the engine calibrator to simply plug in the data and work with confidence knowing that fuel mass delivery is “as modeled” and concentrate his efforts where they belong.
Our new fuel injector test bench, built completely in house, has the capability to quickly generate useful calibration data. We have validated our test results to within just a few percent of OEM data and published data from recognized industry experts in racing fuel injectors.
For race teams, this gives us the ability to know exactly what one particular set of injectors does, rather than assuming that generic published data for the part number matches your samples. Given the accuracy of modern standalone ECUs, and the ability to trim individual cylinders, chasing unknown injector variables should not be part of the race engine calibration process.
For injector suppliers, this means we can take a representative sample of your injectors and create the data that your customers are asking for to be able to use them successfully. Let’s face it, injector characterization data used to be rare in the high performance industry, but now even recreational tuners are savvy enough to ask for this (rightly so!) and will only buy injectors that come with proven reliable characterization data. Of course, it’s still up to the injector supplier’s Quality Control group to make sure that what they’re selling matches what we tested here for characterization.
