Gonna buy 60# injectors... is flow matching worth it?

Huh ? I think the deviation for OE applications is like +- 2% for most stuff. Most companies flow match them into sets however.

so additional flow matching isn't needed is what you're saying?
It shouldn't be but to be honest I have gotten a few lazy injectors over the years so having them checked if it only add 10-15$ to the price is good insurance.

Price is $100 more for flow matching, which kind of made me go :eek5:
thats rediculous. Are you planning on running these on a Ford PCM ? If so you might want to rethink that. These injectors and Factory ford pcms do not get along so well. I ask becuase your name is VT maruader.

03 ford EEC-V yes. As I understand it, I'd need to run them like I do my 42s and trick the EEC into thinking they are something else and my displacement is different etc. I'm sure it'll be a pain in the ass, gotta say the one thing I hate about my car is the EEC
issed:I have seen some issues with the driver being a bit lazy and having some low speed fueling consistency issues. Could just be the older 4v motors the early eec5 stuff.
why not set the injector slope correctly for the injectors ?

did you go for this business of additional flow matching? or did you just get a set of 8 and let em run?

M-9593-LU60 is what I found on the ford racing site
Static Flow Rate (GAS): 62.7 lb/hr = 646 cc/min = 474 g/min
Dynamic Flow Rate 2.5ms PW @ 100Hz (GAS): 20.2mg/pulse
Coil Resistance: 12 Ohms (This high-impedance injector will work with all factory ECM/PCM injector drivers)
Gain: 0.11ms/mg
Offset: 0.055ms
Turn on time @ 14VDC: 1.14ms
Turn off time: 0.85ms @ 600KPa
Factory Tollerance: +/-6 %
Spray Pattern: Cone (4-Hole)
Connector: Minitimer (Bosch EV1)

Those were the impedence ranges I was talking about. Had a hell of a time with a 98 cobra running a stock pcm and 60pph injectors. The low speed fueling would get messy at times. I wonder if they upgraded the drives in the later pcms to better handle the loads of the newer injectors.

I don't know the specifics but I do know that my 03 EEC is very very different to tune than the older ones
The later EEC v systems use a much different strategy and I know they made some change in the electronics. They did switch to a more pencil style injector which should be in the 12-14 ohm range. I know the older mod motor box have struggled with those injectors. I have talked to a few other tunners and they have all reported on teh older cars the same issues I have had with those lower impednce injectors.
As for the later EEC V units Like I said I know they changed some things around so the may have fixed the driver stability issues. Let me know how it turns out.

the eec IV and early eec v cars all had 16-18 ohm high impedence injectors. These newer Pico style injectors like the motorsport 60pph piece being discussed here are 12-14 ohms. Not a true low z but it seems like the pre 2000 eec v system and the earlier eec Iv systems do struggle to run these.
