PRECISION RACEWORKS STAGE 4.5 FUEL SYSTEM UPGRADE | DIY

[@paulkline1522]

In the middle of installing this on my F80, can verify the sending unit with secondary pump is a major pain in the arse. Great video and general how to! Im using the Motiv Reflex+ to switch the secondary pump on and off, and Im also using the regulator as a rising rate.

[@Futemire]

Well damn, I was hoping I didn't have to drop the tank. 26:06 "This would be tough to do by yourself, imagine rolling around on the ground trying to do this." Lol yeah, that's me. 🤣

[@RWattz24]

While you were testing the fuel pressure with gauge was the car running or off and the plug you jumped was from where?

[@NoClutchGarage]

It was off and the plug gets jumped by the battery.

One thing i dont understand all this upgrades for the fuel system does it make any sense when the injectors releases always the same pressure or they spray into the cylinder in order how they are design from the factory or any of market software what is a minimum flow difference...so how this work meanig you can turn on the flow in the injectors like you turn on the flow on the water hose bib?

[@NoClutchGarage]

Yes you can increase or decrease injector duty cycle. The fuel system upgrades allows for more fuel flow particularly ethanol fuels. It takes about 30% more fuel mass to flow the same amount of required to produce the same detonation energy as gasoline.

Do you hook up the boost reference? I keep getting mix reviews, I didn’t hook it up on mine?

[@NoClutchGarage]

I did end up hooking up a reference later...

[@willm2624]

Do you have instructions to wiring it up to reflex with that harness?

[@NoClutchGarage]

Depends on your engine. Motiv has a guide on their website!

[@willm2624]

@@NoClutchGarage it’s the b58, I couldn’t find the guide on motiv’s website showing how to skip the pressure switch and wire to the reflex.

Does that vacuum line on the fuel regulator go anywhere? Or do you cover it

[@NoClutchGarage]

I covered it. You can use it but not for my setup.

[@M4FIA-g5l]

@@NoClutchGarage hey, so im running a single turbo application and my wastegate is externally controlled by motiv reflex. Before when i was on twin turbos, my vacuum line was blocked off but now that im single turbo, is there a need for me to connect the one to one boost refernce to a boost source? the instructions by precision say never to block off the port but to leave it open to atomsphere.

[@M4FIA-g5l]

did you use the one to one boost reference port on the fuel regulator?

[@NoClutchGarage]

Yes, I do now. I did not do that back then.

[@narcopak3037]

How do you Integrate this set up with port injection

[@NoClutchGarage]

This is separate from port injection.

[@leomunoz2422]

i had a stage 3 and idk how you fitted everything with the top hat on , i had to take it off finally afters hours trying this video way.

[@NoClutchGarage]

It’s very difficult

[@friguy4444]

Oh.... I was very confused until I figured out you're driving the B58 and not the N54 lol. The video doesn't say what car you're working on and I was just watching fueling up grade vids not realizing yt won't just send what you haven't specified. 😂
