Patch for Charcoal purge on 7747?
Has anyone patched the 7747 code to control the charcoal canister purge (ccp)?
I would guess that rbob has some code for his ultimate tbi code, has any one else done the same?
What are other people doing for the ccp with a 7747?

I used an earlier canister with out a purge valve. A line to the tank, and a line to the throttle body. The TB end was ported vacuum with a restriction.
Never did patch the stock '747 code for CCP.

That is a very elegant solution. Thank you.
My purge valve and solenoid are not connect to the canister, that must mean that I have an older one (82 vette)
What kind of restriction did you use?
The extra fuel vapor must affect the tune of the vehicle, correct?
