CA18DET & Denso MDL560P (Evo 560cc Injectors)
Posted: Sun Jul 15, 2012 10:33 am
Good evening everybody, this is my first post here and i would like to begin with a big thumbs up to Matt and everybody involved in this amazing piece of hardware and software. Hello to the community as well!
I have a fully forged CA18DET with the following specs.
- Supertech 84mm (40 thou) pistons
- ZRP Connecting Rods
- ARP head, main bolts
- Cometic Gasket
- Garrett GT2860RS turbocharger
- Genuine and properly working Z32 AFM
- Denso MDL560P 560cc Evo injectors (pink ones)
- Walbro 255lph fuel pump
- Stock fuel pressure regulator (36 psi).
What i am trying to find out, is if anyone is using these injectors for their engine so i can get a "in the ball park" K Value.
I have been able to retrieve the specs of the injectors which are as follows:
So i can safely assume that the latency needs to be 620μs (though NIStune wants the latency @ 14V i think this value is in par).
However, i seem to have hit a sweet spot at K Constant of 270. I would like some feedback on this one if possible so i can have a rough estimate.
Every opinion counts, thanks in advance!

I have been able to retrieve the specs of the injectors which are as follows:
Code: Select all
Denso MDL560P
Low Impedance, Mitsubishi Evolution VIII
.62ms @ 13.8v @ 38psi
1.03ms @ 8.66v @ 38psi
Battery voltage correction: .08ms/v
.76ms @ 13.8v @ 38psi w/DSM injector resistor (6 ohms)
1.28ms @ 8.66v @ 38psi w/DSM injector resistor (6 ohms)
Battery voltage correction: .10ms/v
Flow rate: 520cc @ 38psi
Tests on the Evo VIII injector were performed at 38psi and with a DSM injector ballast resistor to accurately represent the injector operating environment when swapped into the DSM platform.
However, i seem to have hit a sweet spot at K Constant of 270. I would like some feedback on this one if possible so i can have a rough estimate.
