Recently installed larger injectors and I saw the stock ifr table was at constant value across the range, so I increased it by a margin ((larger inj/stock inj)*stock values) and left it. Then when I plugged in values into a spreadsheet the values where scaled upwards slightly.

What is the purpose of scaling the ifr table in a slight curve upward?

 

with a stock regulator, it increases pressure with an decrease vacuum. look at the ifr table, it has kpa's across the top from 100 down to 20. the lower the kpa (vacuum) the more it increases pressure for engine load.

 

could this be the reason (cure) I am seeing the same injector pulse width wot with the 30lbers as I was with the 25lbers not scaled properly?

I also have a 17ms inj. pulse width running SD and 20 ms inj. PW running a tuned maf
any thoughts.

 

these are the scaled values I got from 0 to 80 kpa with

Injector Rated Fuel Pressure: 58
Your Fuel Rail Pressure: 58
Injector Rated Flow Rate 30

does this look correct
