| Superior injector pulsewidth control |
| The Low-Z extension board provides faster injector switchoff and obsoletes powerflyback for new installs. Please see GenBoard/Manual/Flyback |
|
* beside VEM's advanced injector-opening model (SW solution)
* powerful flyback HW helps injectors close faster for even better control |

This page is obsolete ! Only useful when verifying old installs. * beside VEM's advanced (perhaps a bit overengineered) injector-opening model (SW solution) * higher flyback voltage after injector output is deactivated helps injectors close faster for even better control |
| ** especially smooth idle is hard to achieve with big injectors especially the fuel delivery amount is different among injectors (or varies from cycle to cycle) for short pulsewidth. As a rule of thumb, 1.4 .. 1.5 msec is always difficult. Usually gets somewhat easier if idle injector pulsewidth is around 1.7 msec or higher |
| * support for injector-sets with poorly matched (different) injopen characteristics |
| * better result for injector-sets with poorly matched (different) injopen characteristics |
