good question Jesse

like you, i agree that if you've got a reasonable wb lambda sensor and controller it's relatively easy to setup the fuelling reasonably accurately, but what about the ignition?

what tools do we need (for example det cans, knock sensors, EGT probes, accelerometers etc) to be able to setup the ignition maps well? and what are we looking to do in all areas of the maps? for example on max boost we want to advance for power but not too much for det, but what about coming on boost (where we may want to run not as much advance for higher egt temps to give energy to the turbo for faster spool up, for example), around idle, below idle (big advance to get speed up again?), cruising, gentle acceleration, off throttle (cut ignition and fuel?).

many questions in there i'm sure stu, but we'd appreciate your experience and teaching as much as possible (and any other tuners, pro or diy)
