63# injctors

Do any one tuned ford 3V with 63# injctors ? ( I need Calibration Summary)

Ford has all of the injector summary sheets on the FRPP website:

The various injector summary reports are at the bottom of the page.

I use the same summary her but same ,i use to work with 63lb/hr Siemens . i have my own tune it work fine with this injectors but too rich .

Usually 63# are measured at 3 bar, so they are actually normal 60's @ usual Ford's 39psi.

I KNow that mate but whaat are happan is lumda fule read lean & rich in same RPM .in the low rpm read too rich .what i knoe in gm if you sive for the 60s in work fine .

You don't control fuel by RPM, but by Mass of Air.

As Greg linked you to, here is Ford Racing's (different department than "Ford") values for those injectors:

http://www.fordracingparts.com/parts...-9593-lu60.pdf

Also, just so you'll know for sure, as lito mentioned, the 63.5# injector you state is actually a 60# at 39.x psi (what Ford uses for fuel pressure), so Ford's part #M-9593-LU60 is the same injector, provided yours is the Siemens Deka (it'll be carved into the injector).

Now look at the Ford Racing values for the "ALOSL" ("Flow Rate Low" in HPT) and "AHISL" ("Flow Rate High" in HPT). Ford has them listed in lb/s. HPT has them listed in #/hr. So all you need to do there is take Ford's value and multiply it by 3600 to convert seconds to hours. i.e. 0.016741 * 3600 = 60.2676, and 0.017552 * 3600 = 63.1872.

Another thing, Ford Racing's "Pulsewidth" value for the 60s is listed as "MINPW (ms) 1.391" (expressed in milliseconds). That's a bit high, and you'll probably never get the fuel trims at idle correct with using that value (the injectors won't pulse properly). I know this because many of us "in the know" tuners have tested them against other "proper" data supplied to us from internal and external Ford engineers and calibrators. So, I'd suggest to set it to 0.94986, and try that.

Furthermore, on the "Injector Offset vs. Voltage" function in HPT, you're gonna fock yourself if you copy Ford Racing's "FNPW_OFFSET" values direct from the pdf file. Why? Ford Racing shows the values for the parameter in EEC-V specs. The EEC-V pcms has these parameters listed in seconds, and the the newer Oak pcms have them in milliseconds. Therefore, you just take the values for the EEC-V pcm and divide them by 1000. Here's Ford Racing's values in the proper format for HPT:

	PW Offset
0.00	0.0025900
0.00	0.0025900
0.00	0.0025900
6.00	0.0025900
8.00	0.0014410
10.00	0.0009210
11.00	0.0007580
12.00	0.0006360
13.00	0.0005180
14.00	0.0004090
15.00	0.0003120
15.90	0.0003120

Notice the voltage difference on the left hand column? Open up the Injector Offset parameter and then click on "Volts (V)" on the left, and then replace the values with this:

	V
0	0.000
1	0.000
2	0.000
3	6.000
4	8.000
5	10.000
6	11.000
7	12.000
8	13.000
9	14.000
10	15.000
11	15.900

Don't forget to copy in the other values Ford Racing lists:

FUEL_BKPT (lb) - "Breakpoint" in HPT
FNPW_BKCOMP - HPT hasn't given us this parameter yet, unfortunately (SCT has, tho ).

FNPW_LSCOMP - "Flow Rate Low Mult vs. Pressure" in HPT
FNPW_HSCOMP - "Flow Rate High Mult vs. Pressure" in HPT
FNPW_OFFCOMP - "Offset vs. Pressure" in HPT


These last four are important for when fuel pressure changes on the EFRS (Electronic Returnless Fuel System) vehicles.

Once you input ALL of these parameters properly, then you need to do as Eric said above, and dial in the MAF transfer. That is VERY important. Without telling the pcm how much airmass is entering the engine, you'll never have your fueling correct.
