Guys,
Here is a link to an in-depth overview of the L-Jet found in our cars I have used this to resolve some issues with my GTV6 and E30s.
You will find it under Tech Articles it’s a bit long 39 pages but is very complete I printed it a number of years ago and refer to it often.
I also purchased a manual Aux Air Valve from Greg and installed it in my Alfa and have been very pleased he writes about it on pages 17 and 18. I did not find the valve on his home page for sale you may need to email him for one. Once installed it works just like a manual choke when cold starting.
