there's several threads on this, i've got several floating around somewhere. Figure out what your injectors are at 4 bar. For example my 520's are 598's at 59psi. Then adjust your k value accordingly. Your latency (void blast off time) will remain the same. As well as your tp scales and ttp min and max (pulsewidth correction factors.) Pretty simple mod as long as your base bin is correct.
yea i konw its really simple but i just cant figure out how to come up with the right values. the whole oldvsnew inj cc formula doesnt seem to add up when i try it...
If your doing this for b14, i noticed it doesn't make sense either. I have no idea how you go from a 259cc injector at 298 k value then 4 bar 370's is 399?

This is really easy to do if you have access to a wideband....
Just Set the FP to 4 bar then start lowering the K-value in 1000 at a time until you reach the same AFR value at Idle but... you might have to tune your WOT part of your bin. for the increase of fuel from your injectors....

bigger injectors have a lower k value... 520's are around 300 and 370's are 399, you also have to take your maf into consideration.
