Hi there Matt and all

What computer is controlling your fuel and spark Matt?

Ive left the timing of the EC2 on the Renesis 4 port at Tracy=E2=80=99s def= ault and haven=E2=80=99t changed it but was wanting to do some experimentin= g.
I take it that the timing setting in the EC2/3 will vary the whole timing c= urve over the rpm/load envelope.

Cheers

Renesis 4 port EC2 EM3 RD1-C
