Did some logging using a hand held scanner. I need to know if my timing is ok & also can anyone give me a formula for coverting o2 voltage to a/f ratio?

Run is from 3rd gear to 4th. Mods are BR stage 2, 264's, fuel pump & base flash. Running pump gas (93) with boost going to 23psi & dropping to 20psi.

RPM ===== 5777 --- 6543 -- 6867 --- 5430 --- 5855 -- 6230 --- 6563 --- 6863
IGNITION == 7 ------ 11 ------ 38 ------ 5 -------- 8 ------ 10 ------- 12 ------ 14
MAF ===== 36.36 -- 37.83 -- 9.12 --- 34.11 -- 36.11 -- 36.98 -- 37.66 -- 37.91
O2 Volts == .92 ----- .92 ----- .84 ----- .94 ----- .94 ---- .94 ------ .94 ------ .94

I know that @ 6867 rpm it is off but that is when I shifted from 3rd gear to 4th gear.

 

That looks kinda low to me, i have 18 degrees at 6750 and 21 past 7000 and thats on cali **** 91 ans 22 lbs of boost.

 

free bump as I am also looking for a formula to convert voltage to something resembling lambda

 

timing looks like its a little low, .90-.94 seems to be pretty safe usually for 02 voltage. Did you get the flash after you got the cams or before? If flash came before cams then maybe your timing is lower then normal cause your car is running in different timing cells (apperently the cells your running in have less timing); since it is flowing more air with the cams; this should put you in a different/higher "load" range which should put you in different timing cells. But this is just an educated guess. Turn the boost down to 18psi so your engine is not seeing as much air flow, and if your timing goes up a few degrees then assuming there is no knock what i said is prob. right.

 

Flash was done after all the mods. It is a base flash from Al.

 

I guess you can ask Al if that is how much timing you should be seeing?
