I just need something nice and close. I am going to get the car tuned eventually but don't want to ruin it in the mean time.
Thanks,C

use my injector flow rate calculator on the top of this thread under my sticky. that will give you your IFR values... thats all I changed on mine and i have those injectors...it ran fine. i did lower my volts vs kpa table by 10% and it smoothed things out more...but every car is different

Do you know the static flow rate at 3 Bar? Many times a vendor calls an injector a xx lb but that's not exact enough to accurately calculate the IFR table. I would ask the vendor if they had a flow sheet on a similar injector.

The static flow rate at 3 bar is 43.77015 lbs/hr now depending on how I convert it to 4 bar it comes out to 50.49 or 50.54 so I don't know which one is correct.
I don't have excel so I can't use the spread sheets..

Here's your IFR table:

Code:
Injector Flow (lb/hr)	50.54213388	50.85712779	51.17018269	51.48133396	51.79061591	52.09806183	52.40370403	52.7075739	53.0097019	53.31011767	53.60884998	53.90592681	54.2013754	54.49522222	54.78749305	55.07821298	55.36740643
They are 50.54 @ 4 bar.

You can download Open Office for free and use it. I have it on my tuning laptop because I don't want to pay Microshaft for more than one copy of Office 2007.
