Thanks Terry,
This is a complete 1380 engine build by SC, they provided the Delta ECU and complete fuel injection system as part of the build. Effectively, it should have been a 'fit and go - turn key' replacement.
It didnt include a lambda though. We replaced the original lambda with a new Bosch unit. Im realising now that fitting this to the manifold tube close to the exhaust port isnt best and should go down by the y-piece.
What would you recommend (if you can) re lambda to use?
Cheers,
Damian
