High - Low Octane

[iGoRa]

How does PCM know what type of gas do I use?
Other words , How PCM does choose which table to use?

I think it just detects alot of knock and reverts back to the low.
but I could be wrong!

thats easy :)

when the PCM sees knock is goes to the low octane table.... then as time pass's it slowy gets back to the high octane talbe

if you watch your scaner after knock it only commands whats in the low octane talbe :banana:

hope this helps
