Hi Finn

Sorry, I misunderstood. Too many things on my mind at work at present.

When I get to the EC3 mods I=E2=80=99ll:
a. Test the EC3 with new clamped CAS input. If no change and it still =
runs like a dog on two legs  -
b. I=E2=80=99ll reprogram the chips with your hex code and retest.

On another note:
Still trying to decide on whether to pay to have my 4 blue secondary =
injectors cleaned and tested or
buy new injectors, New ones are cheaper on eBay but are they knock offs =
that I shouldn=E2=80=99t trust?
Cleaning is $40 each. New ones are $20 each!

Cheers

Steve Izett
