[Diy_efi] Typical boosted ignition timings

[Marc Reviel]

Based on a 1994 Porsche 3.6L Turbo engine/car.  Lots of head and 
manifold work (converted from CIS to EFI), GT2 cams.

Yes, 19 degrees is what some others have said, too.  581hp was run 
with Lambda set at 0.90.

>>Now, I am interested in finishing the tuning at a max boost of 
>>1.2-1.3bar (~18lbs) on 93 octane.

>>Any one out there have any typical timing/AFR data on something 
>>remotely similar? Or any good websites with pertinent data?

>>Thanks in advance!
