LS7 cold start up too rich

[billyram]

I have a LS7 crate motor that runs too rich open loop cold. What's the best way to tune this problem using FlashScan V7.5?

You would have to get the MAF table corrected... and possibly the VVE table.

Where can I find the MAF table? Found it.
The values are 600rpm----25
1400-------60
2200-------100
That seems a bit high for 600rpm

MAF table axis is in Hz which do not correlate to RPM... how are you matching RPM to g/s...?

you have to disable the VE/VVE by seting the High Speed/Dynmaic airflow parameter to some low value (400 rpm), and then you have to log using a wideband, and from the log you can make a Hz x g/s map to correct the MAF table.
