60# INJ IFR Table HELP

[Lumpo]

Okay I upgraded to some 60# Siemens high imperdance injectors and im having trouble trying to find out what exactly im suppose to change in my tune to properly tune these injectors and what values to use. If anyone has a good IFR table for 60# injectors please post it. Also let me know if I need to change more than just the IFR table. THANKS!

Injector Specs

Coil resistance: 12.5 OHMS/ High impedance/ High-Z
Static Flow Rate @ 43.5 psi (300KPA) w/Gas 60Lb/hr=630 cc/min=453 g/min
Static Flow Rate @ 87 psi (6000=KPA) w/Gas 85.7 Lb/hr=630 cc/min=900 cc/min=648 g/min
Gain: 0.11 ms/mg
Offset: 0.055ms
Turn on Time @ 14VDC:1.14 ms
Turn Off time @ 0.85ms @ 600 KPA
Connector: Bosch EV1
Series: Deka 4 (Deka IV)
Orifice Type: Multi Orifice
Spray Pattern: 30 degree spray cone
Factory fitted with Viton upper and lower o-rings

Here is my current tune....

You will have to change all the injector characteristic to make them work correctly. IFR is easy what fuel system/pressure are you running?

I used a IFR calculator spreadsheet to determine my values with those same injectors. I wound up with 69.3 @ 0kpa and 79.5 @ 80kpa , and you can interpolate horizontally for the rest. I've seen other tunes that were slightly higher and others slightly lower.

Can you put up your 60# injector tune so I can check it out?

I have an adjustable fuel pressure regulator I haven't decided what pressure I should run yet. If anyone has any help to offer please post. Thanks.

My injector values are working well , but I'm not done with them yet. The IFR is good but still fine tuning the rest. I drive my car with these values everyday, so I know they are working. You are welcome to take a look. OH , by the way , I'm not using a special fuel pressure regulator or anything like that. I think if you're using a manifold referenced FPR , then all the values in your IFR table will the same number.

THere's also a bunch of tunes with 60lb injectors in the tune repository. By the way , my fuel pressure is 58psi , so my IFR is based on that pressure
