LT1 aluminum heads swap

I agree, quite a difference. Perhaps the bin I have is just different, or 94 was was different, idk..

Is there a way to monitor the knock? I have never experienced a knock on this engine and I am afraid to miss it by feel..

Speaking about the fuel, I noticed that the flow rate numbers are lower for f-body bin.

yes the injectors are a different size
but you'll be okay
the datalog has knock retard and knock count
actually the knock system is another consideration, the bbody and fbody sensors and knock module are different, probably because of the heads

Finally put the engine back together and ready to modify the timing tables. What I noticed that the bin for f-body has spark advance table bias zero, and b-body has it set at 20.
Do I just leave it at 20 and simply modify the main spark advance table?
There is also Minimum spark advance bias, which is zero for for f-body and 10 for b- body.
Thanks

depends what XDF you're using. if you're using my EEX xdf the bias value is part of the table calculation so it is accounted for in the displayed data. if you change it your timing will have to be rescaled by the same amount. it affects the minimum and maximum spark values, a bias of 20 gives you 60 degrees max and a bias of 0 gives you 80 degrees max. you wont need more than 60 degrees so 20 degrees bias is fine.

Thanks! I will just tweak the main timing table slightly.
