Need google share to view it.... share it same way you did before.

I don't know if this is 100% accurate, IAM effect is kind of complicated and hard to explain. the basics is it is pulling timing if its under 1.
but
the effects it has is calculated off of a portion of total timing. If at 1 IAM and WOT you have 25 total peak timing. There is a parameter (not sure what it was called) that is adding something like 7 degrees of timing at 100% IAM or 1 IAM. when IAM is at .7 or 70% of that 7 degrees which is 4.9, so 7 - 4.9 = 2.1, so 2.1 degrees of timing would be pulled from that 25 and you would be at 22.9 degrees of timing.This might not exactly 100% accurate but its the basic gist of what is happening, its basically a percentage of a smaller portion of total timing. the difference between .7 IAM and 1 IAM is like 3-4% less max power or about 5-7whp NA.
