8-12 is a bit much, i'd suggest adding more fuel in up high to your tune to compensate for now so that you don't blow it up while racing, and about your spiking, we would need to know more information, and more about the parts you have that control your boost...

These are my maps (high octane only)
low octane maps are the same as stock!

Thank you for your time EvoJustin

You need to make your low octane maps similar to your high. Copy the high to the low and detune it 2 or 3 clicks. Having drastic differences in the high and low maps can make the ecu do some odd things.

yes, that's what he is saying, you need to add a small percentage of fuel in at the rpms ranges that you're getting knock so that you don't get knock anymore, usually at 8-12 count i've seen adding 1-2% more fuel erase it entirely

Timing is to high from 5500 to redline as well... lower them... I would aim at around 10* from 7500 up... but that is me...

Hi, how about the far different on the High & Low Timing maps? Do we just need to make it say 3 deg lower each?

I will test my new maps as soon as possible!
I create 2 new mivec maps little more aggresive and i think that they are better in low/high rpm.
i will try both of them, but i think mivec4 mapis better.
what do you think?

Thank you for your time!!!
