Speeduino supports an ever growing number of crank and cam decoders and trigger wheels. This includes some of the more common OEM setups as well as those favoured in the aftermarket (Such as the missing tooth wheels).
The list below includes all those that are currently supported. They each lead to a page with details on using the decoder (These pages are a Work in Progress)
