Hi,

What do you want to know - Practical examples from proven turbo ECU tunes, or theory from books??

Cheers

depends what do you want to do? as a general basis i usually advance 1-2? BTDC, you need a good A/F meter to keep an eye on the mixture, not to go too lean or rich

Its a deep subject, discussions on a forum don't do it justice.

First understand gasoline combustion and laminar flame development, then you will better grasp how to optimise timing events.

For sure you need alot more than afr feedback...torque, port temperatures and cylinder pressure vs crank angle are standard.

Best learn about knock detection if you're going to look at Ignition timing in turbo cars too. The two are intrinsically linked.
