With all my projects I like to share the pinouts for the ecu should some one else want to have a crack. This is to give those people that are interested in running a turbocharged zetec engine on a budget a head start

well here you go.

Mk1 Focus Rs ecu code 6MYD.

WARNING I WILL NOT BE HELD RESPONSIBLE FOR ANY LOSSES OR INJURY RESULTING FROM USE OF THE INFORMATION CONTAINED WITHIN.

The key to using the ecu is the Pat's immobilizer. You must get at least one key with chip that is paired to the ecu.
