After that i push the timing until im scared or it pinks. It works for me, just wondering if thats the norm? Obviously you may have to re-visit the afr at various stages to get it perfect, i tend to aim for 12 or under afr to be safe on boost and i like it to be 16-17:1 light throttle, richer at lower revs.
Hi everyone just read this thread as im very intrested in learning about this and i thought i'd ask afew questions as yous seem to know quite a bit.
You say you first establish a safe ig timing map, How do you know that it is safe? What do you do just lock the timing to a certain point?
Also you say that your afr is 16-17:1 on light throttle but i thought that would be to lean i thoght it should be closer to 14 is it safe at 17?
Thanks Bram
