Vacuum reference on 262
I noticed that on my stock tune, the injectors had a flow rate of 2.7891 g/s all the way across the flow vs vacuum table. Is this because the factory fuel injector spider fuel pressure regulator has a vacuum reference? Usually I have seen the injector flow as a curve.
Also, are you guys running boost using the vacuum reference on the FPR? I was looking at something like the Aeromotive A1000. |

Re: Vacuum reference on 262
I run the vacuum refference. If the vehicle runs a vac refference the flow vs vacuum table should be flat.
In my opinion the vacuum refference is better because with large injectors at idle they would seem even larger so you would need really short pulse widths at idle. All the vacuum refference does is keep the fuel pressure constant with respect to manifold vacuum. |
