Yes a 1:1 boost reference fuel pressure regulator.
Nothing too extreme, 60psi base and a boost reference to keep the fuel flowing during high boost.
My question is, can I just run a charge pipe reference instead of a manifold reference to keep my fuel pressure at 60 psi, when not in boost?
No you cannot. When the turbo spools up a little against a partially closed throttle, you will get extra fuel, as the charge Absolute Pressure will be greater than the Manifold Absolute Pressure. Next time, under a different load scenario, the same RPM and Manifold might be at a more open throttle, so then the MAP would be closer to the Charge Pipe. Now LEAN.
I really believe tuning would be a total nightmare.
Wow, just wow! Is almost looks like someone dropped an iron on my VE table and it's still rich in high boost. I think I am logging about 70% injector duty way rich now, where I was at 115% barely able to hit my AFR target before. It is amazing how much difference the pump and regulator have made.
Haven't turned my EBC on or been past about 5500 RPM. I basically stomp the throttle and watch my AFR dip into the 10's, then let off. Go examine my log, adjust and repeat. Won't be long now.
Not yet. Finally comfortable stomping on it without worrying about hydro locking the thing. Still a little rich, but almost there, don't want to **** around above 250 kpa. Still a ton left on the table for the original Flow Force injectors with a proper pump and regulator. Amazing difference! Thanks for the fueling bits Andrew and George!
And yes, it is noisier than my Wally 190. I mounted my regulator under the fuel pump access panel and I think the regulator itself is pretty noisy.
Checking measurements for a different bracket and slightly longer return hose, I had the panel open again so I thought I'd try the image loader once more. Mods feel free to remove this post if the picture ends up site cloggingly huge.
Aww ****! They seem huge again, WTF is up with my phone
When I do finally fill up with e85, do I need to add timing to idle or can I just multiply my req fuel 1.33 and up my cranking pulse. I just don't want to get stuck at the e85 station in SF. I think I have K24MADNESS''s e85 project we had running, maybe I will have a look at that.
You can, don't have to, but it helps. Esp in the startup sweep cells. You will have to adjust your cold start in addition to req fuel. That's basically it.
Target 12 flat in boost or high 11's if you want to shoot for the moon. Looking at your current spark table, you can start with at least 5* more basically everywhere.
I'd like to be the first to congratulate you on achieving 1000 semi-coherent half drunken posts in this build thread while pumping an absurd amount of boost through a $200 turbo.

I mean I sure as hell never expected someone to put 25+psi through one of my turbo setups.
