I have 160lb low imp injectors I'm trying to run in my 97 Mustang 5.4 turbo car. I have the versafueler to run them.
My question is, how are others scaling these injectors?
This is where I'm at....
Found out my "no start issue" was from the fact that the power wire I had running the VersaFueler would NOT send 12 volts when cranking. Thus making the box not have power when cranking. Fixed that.
Next, ran like poop. So I went back to the tune.
I am now running these values:
Fuel injector Break Point .000137
Fuel injector Hi Slope .017542
Fuel injector Low Slope .022456
Fuel Injector Min Pulse Width .000821
Manifold Volume: 4.875
Engine Displacement: .000908
I took the values from here ( http://www.boschdealer.com/specsheets/0280150846cs.jpg ) I multiplied those values by .5 . Then I multiplied my manifold volume and displacement by the same amount. That's how I came up with the values I'm running above.
It runs, though its rich. It WILL NOT Idle, and the throttle response is very laggy. Unless I get it over 3000 rpm and hold the throttle there and slowly bring it down to 1300 rpm, it will just die. Also if i don't have the MAF plugged in, it won't even start. (though I do have adaptive learning off)
So that is where I'm at now. Any ideas? I'm playing with the "MAF translator function" now.
