Re: afc hack tuning
I usually run a 30/70 cross over but it changes per car.
240/450 = 54%/100%
So we need to take 47% of the fuel away from 450cc injectors to run them like 240cc injectors. Now this is not a perfect conversion because there are more factors than this, but it gives you a ballpark # to start with. As for settings under boost that varies a lot, but under WOT and full boost of 8-12psi a setting of -35 to -30 on the AFC should keep things good and rich.

Re: afc hack tuning
for god sakes get rid of that piece of shit afc. They work terrible on hondas and if you dont have something to pull out ignition timing then you WILL blow that motor up. You can sell that afc and for almost the same amount of money get a chipped ecu and get it tuned properly.
