Co3 stft with command afr 12.00?

[69camaro5speed]

trying to figure out why i am getting cl fuel control with commands richer then 14.63
i am getting stft with commands in the 12.00 afr ?

here is the tune before i get ask

looks like bo302 was the problem

I'm glad you got it fixed, but if you could, can you explain why the barometer update parameter was the problem? I don't think I have ever had to play with these values before. Was you MAP sensor not reporting the change in altitude? Or maybe the PCM wasn't able to adjust due to a change in altitude?

You don't have any CL/LTFT/STFT/SOL enabled in the tune...

when AFR is commanded richer than stoich, your log shows not CL/STFT, but rather it shows WO2AFR overshooting/undershooting.

so 20:20:05:312 in the log with a comand of 13.79 and a stft of 15.6 is really not there

To fix the problem I made my afr table read 14.681005 (like b3601 is set )to make it go into stft and any thing richer it cuts off the stft like it has done in the 200 co5 tunes I have done.
They have a stoich of 14.628573 that I tryed to use on the co3 but there are set to 14.681005 in b3601

so that and setting the barometer update parameter so it wasn't trying to update under boost

now I have a working afr table and the map reads more them 105kpa under boost like it should
all is well

If you work with units of EQR, then you don't have to stress about matching B3601 to the 6th decimal place.
Stoich is 1.0 and B3601 is just for the computers final internal calculation to determine fuel mass.
