Hilly (another Pete, I see !) :

My carbon cannister & purge valve was a rego requirement - it all had to be seen in place & connected. However, being a "cheapo", I bought the basic Autronic ECU & it only has 1 aux output, so it got used to control the purge valve (mind you, it was only set to kick in at 6000rpm to ensure that it didn't blow in the middle of the emissions testing !). Once rego was achieved, I changed the aux output to drive the rad fan relay & just left the CCV connected in the closed position. Every few months, I'll do a manual purge of the CC with the air compressor.

I'm not sure what triggers off the CCV in a stock RF/Motec setup, but I am sure that it is "big user" of vacuum when opened - best kept separated from the MAP & regulator vacuum feeds.

Kind Regards,
