Wanted: Tech details on how ECU manages Spark, Fuel, VVTI etc

Has anyone seen any technical publications on the 2IS 350 engine management or mechanical data like; Cam timing MAP data, cam lift, lob centers, spring rates, ignition timing advance curve, how they implemented spark knock pull back, where the injectors overlap and/or run solo, all the unpublished white paper stuff.

Any info or links appreciated. Also if this info exists in Toyota's TIS site, let me know.as I never found it. Maybe I need to be looking in 2005 before production release?

Thanks in advance!

Specifically I would like details on post O2 data (S2 sensors) and if it is used to alter STFT / LTFT's.... as in, will a sim do an adequate job and if not, what is the impact?
Engine, trans interaction, cam timing, spark management, fuel cut modes, how DI and PI interact on cold start. All if that stuff burried in the white papers...

Any info or links appreciated. Also if this info exists in TIS, let me know. I'll buy a subscription.

Thanks in advance!

Friendly bump.... PM me if have info! Thanks
