it's nearly 20 years since EE was released, and i've taken too long of a break from disassembly.

there are two questions i really want to answer this year as i start tuning yet another LT1

1. where does the spark variance in power enrichment mode come from, and can it be tuned. i have (and other people have) observed at least a few degrees of additional timing that can't be explained by other tables.

2. how exactly is the VE table used when calculating airflow in MAF mode. the table lookup isn't skipped when using a maf. setting the VE table to rediculous values such as *1.9 or *0.2 causes a giant swing in AFR, so it's definitely used somehow.
