Filtering
00.45
| 00:00 | Some trigger inputs can contain a large amount of noise or high frequency interference and the ECU can provide filtering of the raw signal to help eliminate this. |
| 00:09 | Ideally, we want to have a nice, clean trigger signal that requires very low amounts of filtering. |
| 00:15 | We would always start with the filtering set to a minimum. |
| 00:18 | If you start encountering triggering errors at higher RPM, you may need to slowly increase the filtering to help eliminate this. |
| 00:26 | This needs to be done carefully, though, as setting the filtering too high, particularly if you're using a trigger wheel with a high number of teeth can actually result in the ECU ignoring valid trigger signals, and this can cause the same triggering errors we are trying to fix. |
