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

Oh, you already reprogrammed them with the fixed code I uploaded?

Thanks Finn.

I’ll add the 2 zeners to the EC3 and test it.
I thought the reprogramming of the chips was right.
MPLABS reported them to be good.

Thanks Finn. Did you previously give us a the circuit? Do you have a sketch of it?
  I’ll mod the EC3 and see if that is the problem.
