  In BOSCH systems, there are TWO adjustments to the final pulse width

  1) For voltage, to compensate for different opening/closing times

  2) A final trim, which corrects extreme (large or small) pulse widths
     to linearize the "squirt" function ..

  They are contained in simple 2D tables ... "maps" if you will ..
