| So your ECU really has to adjust for this varying voltage in some way. It can't just turn the injectors on for 3 ms and always expect to get the same amount of fuel. As we'll see in the next section, a 3 ms pulse at 9v might produce no flow at all while the same 3 ms pulse at 14v might produce 200 cc/min of fuel or more! | So your ECU really has to adjust for this varying voltage in some way.

| - | Obviously, this effect is huge. If the ECU calculates that it needs roughly 50 cc/min of fuel flow (for example), it would need to hold the injector open for 4 ms at 9 volt vs. about 2.3 ms at 12 volt. That's a really big difference and clearly illustrates why it's critical for smooth operation to get your battery table set up correctly. | + | Obviously, this effect is huge.
