The internet is ablaze with rumors that others are offering the same injector as the ID2000, they’re just not matched by the same process. This is correct, there are others offering the same core injector. The rest of the rumor is that the consistency from Bosch is so good that our dynamic matching process doesn’t have any benefit.
This is far from the truth.
The chart below shows flow deviation vs. pulse width for every 10th injector out of a batch of 100. You can see that while flow variance at high pulse-widths is pretty good, there is quite a spread at 2msec pulse-width, where the injector will spend much of its time operating, and where you really see and feel a difference from cylinder to cylinder variations.
At 10msec, the spread is about 2%, but at a 2msec pulse-width the spread is in excess of 13%.
Do you think a 13% variance from cylinder to cylinder at idle and part throttle will make a difference in how a car runs?
Here’s a dynamically matched set of 6. It looks like there are only 4 lines on the graph, but there are actually 6, some are just so similar they pretty much overlay.
