# Header
|
||
|
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)
