#52 injector table

I need the injector table for a size 52 injector...

#52 DELPHI 17113738

Static Flow Rate: 50.0 lb/hr @ 43.5PSI (300kPa) 525cc/min or 6.4gm/sec
Static Flow Rate: 57.7 lb/hr @ 58.0PSI (400kPa) 606cc/min or 7.4gm/sec
Dynamic Flow Rate: 1.1 gm/pulse - 2.5ms pulse width and 10ms repetition rate @ 43.5PSI (300KPa)
Dynamic Flow Rate: 1.3 gm/pulse - 2.5ms pulse width and 10ms repetition rate @ 58.0PSI (400KPa)
Coil Resistance: 12 Ohms / High Impedance / High-Z (No ECM driver modifications required)
Cone Spray Angle - 22.4 degrees - single spray cone. Approximate cone angle for 90% of spray volume
Ball/Seat Design with 6-Hole Diffuser Disc


Big thanks.

Look Here for the spread sheet.

But here is what you want.
If you have a return fuel system you just need the frirst value copied to all cells.

Thanks.

I tried the table and the car wouldn´t even start until i added 25units to the VE-table. And it also made my idle go up 100rpm (maybe it settles later?)

The table is correct for the injectors you specified.

I'm not surprised that the VE table moved on you though. Probably the old injector and flowrate in your calibration was off.

EC

now that i have raised my VE by 25, should i change my cranking VE aswell?

If the car starts right up, no.
If you have long crank times with no fire yes.
If the car starts and then acts up it's a different table:
Fuel Control.General FA Mult Stage 1 vs Time

Yes, It doesn´t start right away... and when it does it idles rough and when i touch the gas it almost dies :(

Any help would be nice :pray:

Are you logging your STIT & LTIT in gear & LTIT Pk/neutral (Airflow trims, not fuel :D)
If they are going very positive, thats part of the problem. I log in g/sec but you can do it in lbs/hr if you wish.

Here's a Thread on logging STIT & LTIT.

EC

No i havent logged STIT....

Should i change my cranking VE back to stock?

I should log from cold to hot, right? with gear and without gear? more than one time? reset fuel trims?

I can use the included histogram from the scanner, named idle desired airflow ?

I cant get it to work the way i want...

Cant you make two histograms(using ltit and stit), one in gear and one in neutral... for idiots like me :)

Just dropped these in on your other POST

EC

Thanks.. EC :worship:

i have these same injectors. did you get them to idle right? mines shows way lean. once got a missfire cel. i need help on these.
