Hi Finn

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

When I get to the EC3 mods I’ll:
a. Test the EC3 with new clamped CAS input. If no change and it still runs like a dog on two legs  -
b. I’ll 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’t trust?
Cleaning is $40 each. New ones are $20 each!

Cheers

Steve Izett
