Injector data request

[Fozda]

It might be a long shot but does anyone have Siemens 80# injectors with a return style fuel system that could send me their tune so I can use the injector data as a starting point for tuning my car?

Maybe these will help? There are more tunes here.
LSJ tune for 80lb injectors, ZFR 6758 turbo, BRFS, Stage 2 turbo cams, gfab2 electronic boost controller (ccannx)
LSJ tune for 80lb Siemens injectors E85, with ZZP Entry Level Turbo swap kit, K04 turbo (Sluggonaut)

Those are good options, I'll definitely give them a look, but I'm concerned the return style system is going to change things.

By return style, I guess you mean referenced pressure?

Yeah, it's a return style system with a boost reference pressure regulator instead of the dead head system that they come with.

I think your injector data is simpler since it's the flow rate at base pressure in all of the cells since the "delta" pressure is always the same.

I have a boost referenced fuel system. I'm not running 80# but I am running 60# injectors. This is my tune at the moment (for the most part). You should have to tune the VE table and the MAF from here. You'll run a bit rich with this tune, but should be a good start.

The best thing I did was get rid of the seimens 80lbs injectors. drivability is much much better with IDs

Funny you say that because I just ordered new injectors today!
