I am failing at trying to find a stock ignition timing map for a my 99Si b16a engine. I want to know what its total advance timing is at 8,000rpm at full load naturally aspirated. AS in from the factory.

any help is appreciated.

i am told it is like 27.8 degrees, but i want more insight

 

Uberdata shows 29.75 degrees.

 

according to hondata s300 its 18.75?

But the b16 greddy turbo map says 22.50

 

i would also like a definate answer please!

 

The crome B16a2 map says 24.25 so, I'm

this sucks, so i have no clu what timing to decay from boost if i dont know where to start

 

for a basemap.. start at the lower portion.. keep it safe

uberdata does not show 29.75 degrees. it shows 26.25* at 0.35 In/Hg and 25.25* at 1.13 psi. these numbers seem to be aboutthe same as the CROME values

 

run 25-26* timing for full load at 8K rpms nd then do the boost retard from there. dont run 28* timing, be safe and run low

 

i stick with my answer i told you last night, 27-28. that's still way under the 33 degress you originally had it setup to run.


here, i'm nice today. two maps, one a conservative timing map, the other an aggressive timing map:

mild


wild

 

Uberdata is based on P72 code where as Crome is based on P30 code. I believe the B16 to run 24-25 deg stock. The B18C runs ~29deg
