Road Tuning: Filtering
Filtering
00.51
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. |
00:10 | Ideally, we want to have a nice clean trigger signal that requires very low amounts of filtering, so we'd always start with the filtering set to a minimum. |
00:20 | If you start encountering triggering errors at higher RPM, you may need to slowly increase the filtering to help eliminate this. |
00:29 | You need to approach this carefully though, as setting the filtering too high, particularly if you're using a trigger or wheel with a high number of teeth, can actually result in the ECU ignoring valid trigger signals. |
00:41 | This can result in triggering errors at high RPM, which is exactly the problem we're trying to fix. |
