DannyBro Bro. Our cars have Air Flow metres. We need plumb back items. Vent to Atmosphere are no good on deceleration of when we let go of the trottle as the AFM detects no plumb back air from the BOV and so the ECU runs rich to protect the motor hence momentarily flooding it and almost and if not stalling the engine.

The POD is fine.

Yes pretty much because as I mentioned earlier. The ECU does not see air returning to the AFM when you let go of the throttle so it dumps fuel momentarily into the engine to protect it.

An aftermarket Plum Back BOV will do the job too. Get a dual venting one if you want the PSSHHHT Noise. Vents to Atmo and some back to the intake .

I was under the impression that only the Djetro version of the power fc did away with using afm's?

personally I'd get a plumb back that also vents some, I had one on my old R34 gtt i think it was a hks ssqv if not then it was a copy

while it doesn't sound quite the same as a full atmo (I actually prefer it) it does the job right and you still get that venting sound.

    • Just planning to have the wiring neat and hide as much as possible.
    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
    • You can probably scrub the rust with a toothbrush or something. After you get the rust off flush well with water to neutralize and you will probably want to also use a fuel tank sealer to keep it from rusting again.
    • The sodium citrate solution is designed to buffer the citric acid to keep it from attacking metal quite so much, the guy that came up with that recipe did a ton of testing on how much metal loss occurs over time and it's nothing crazy unless you forget about it for months:
