If the stock ecu couldn't compensate it would throw a fuel trim rich code-it doesn't and as far as I could tell the off boost fuel curve was the same, same lean spot at low rpm. Maybe your pump setup flows more than mine (stock pump inline with the 255lph) idk.

 

Removed stock and replace with Walbro hi flow hi pressure 255! I have the same setup that AvanteKing is going for...

 

It sounds like coffin has a booster.

 

i would strongly recommend waiting to install the pump until you get a RRFPR.

 

thats what i doing, i trust you guys im not stubborn i understand y its a bad idea to do what i askedlol, thnaks guys, and whats closed and open loop?

 

for the RRFPR, you will need a 3/8NPT tap for the rail (~18$) npt to AN fitting + some AN fittings + feed line + return line + fuel pressure gauge + 31/64 drill bit or a steady hand with a dremel

 

Your cars ECU will operate in closed and open loop, open loop would be any time driving when not a WOT, closed loop comes on at WOT or cold starts. Just changes how the ECU regulates Fuel with pulse width.



Also ^^^^^ there is the guy that can hook you up with a FRP kit!!!



I dig mine, works well, and looks nice!!!

 

bummer, tonight i installed my new oil pan and what not, guide told me to use rtv silicone and i did, well sure enuff there is a tiny leak );; now i gotta rip everything out and redo it, the pan came with a gasket but the guide told me to use rtv, should i just use a gasket? im kinda bummed right now and im going to take a break fr a few days cuz im pretty pisttt

 

Yes. Put a thin layer of rtv along the block,(use your finger to do this)place the gasket on, and a thin layer on the oil pan,(using the same finger technique.

 

Closed loop happens at idle and light cruse where the afr fluctuates between rich and lean averaging 14.7:1, open loop is during acceleration and the ecu controls fuel based on the maf/iat sensor and rpm readings.
