B1219 Low Volatility Fuel missing?

[rally1]

Hi all,

I have a issue with a supercharged and camed L76 2009 Holden Commodore with operating system 12633016.

On cold start it fires up and goes from cranking fuel to around 12afr and runs fine, then after about 3-6 secs it starts to run at 9afr and that can last anywhere from 4-30sec and then goes back to 12afr. It really looks like Low Volatility Fuel Detect but this operating system does not have that option listed, is there a chance that it should have B1219 and its not listed in the calibration or am i just missing something all together?

I have changed the open loop commanded tables as I would normally do with a cam but I just can't get a good stable commanded AFR on start up, any help would be much appreciated.

Thanks

Pretty sure that GM added that calibration in the 2010+ models.

I had a feeling that was the case but that's what it really looks like, it will only do it on the first start of the day and no matter what I do to all the open loop tables and multipliers it will always go to 8-9 afr and run pretty poor..
