Using just this sort of data, we have been able to determine the fuel usage of numerous engines at idle. How did we do that? Magic maybe? Nope…It’s as simple as recording the idle pulse width of a running vehicle, and then comparing that value to the curves above to determine idle fuel flow.

Having this ability has allowed us to steer customers in the right direction knowing nothing more than engine displacement. It has also allowed us to sort the good from the bad insuring that everything we release is a quality piece. By examining the flow vs pulse width curves of any injector we can answer important questions such as “Will this injector provide a stiochiometric idle on a 1.8 liter Honda engine?” “Or a 1000cc 4 cylinder motorcycle engine?”

We don’t need to wait for our pet tuner to try it out on his EVO, or his buddy’s WRX, we know before its ever installed in a running vehicle.

So am I bragging? Not really. Just trying to make a point. If I had to hand this in for a grade, my point, or more accurately my conclusion would be that it is no longer 1985. For that matter, it is no longer 2008.

This industry as a whole has moved forward at a rapid rate, and the ability to form logical conclusions from data, and to expect the availability of that data is commonplace.

Gone are the days of tuning poorly-behaved injectors with little data, and even less understanding of what makes them perform so poorly. Gone are the days of asking your injector supplier for pertinent data and getting a response ranging from a condescending attitude, to a blank stare.

So if you see an exception to this forward momentum, do the whole industry a favor and remind the offenders that its no longer 1985.
