I've got my 1980 911 up and running well with a Haltech R3, ITB, COP, Home, Trigger, DBW, etc. When cold, the engine starts right up. Hot starts require a bit of throttle. I'm using a cylinder head temperature sensor and when the engine is hot, it's indicating around 125°C. Once started, idle is spot on.

I'm looking for an idle adjustment on hot starts or should I be looking at fuel enrichment.

Thanks

Dave
