really? for the lsj?

 

Yep i put it in wen i was diagnosing a fueling issue a few months back. Works good..the cool thing is that summit stocks it so it only a day away for a new pump.

 

 

How long has it been on? Always curious/worried about how different pumps holy up to E. that's why I got a deatschwerks.

 

3-4 months so far.

 

Look wat came today..

 

Good to know they're pretty much plug and play since I get them for cheap!

 

did you retain the stock regulator at 60 and use zzp's to go up from there to add a psi per psi of boost?

 

Yes sir.
The stock system is a semi return style at the filter.
There r 2lines that come out from the tank. The larger one is the main pressure line from the pump. The smaller one goes from the filter back into the tank were the stock 60 psi fuel pressure regulator is. So if u dont plan to run under 60 psi dont bother with it.

 

Tuning is easier and smoother IMO if you just run full boost ref.

 

It dosnt change 60 psi is 60psi
The stock regulator wont affect tuning as long as ur base pressure is 60psi or higher.

 

i am at 60 psi and idle 80 lb injectors at 800 rpm on E85. I just need the brfps to go above that so that is exactly what I am looking for. Do you have a return line from the rail?

 

I plan to do that later but not right now.
I use the stock evap line for the boost referance.
It wasnt worth the hassle of running another line for a full reture style theres no gain at all. The stock system is a poor mans return style so the pump is fine. If the system was a dead head system i would do a return but this works just as well.

 

right I have read that several times, that it presurizes a line out of the fuel tank to the rail then the leftover fuel goes back in the tank from the line T'd off the regulator? Wish i had a visual I havent touched my fuel system yet.

 

No
It t's at the filter mounted under the car

 

thanks going to go read up and dig up some google photos.

 

Here im under my car. Lol
So u have 2 lines goin into the filter.
The larger one is the main line from the pump the other is the return back into the tank.
3/8 is the larger one from pump (-6)
5/16 the smaler one return to tank

 

But as u turn the pressure up the flow of the pump falls off.

 

And yes i know the underside of my car is dirty. It rained the other day so havent steamed of the under side yet.

 

Wat.

I didn't mean the settings and getting the tune set up.
I meant actually tuning it. Logs/revisions. Afr is more stable and predictable at low boost/ transitional areas like ramping into PE.

 

i have read that but it requires a full retune (500 bucks) in my area.

 

2.5+e85+ls4= :-)

 

Add a 445 in the mix and the tq makes you poop a little

 

I already have traction issues in 3rd.

 

Lmao

Alan he learned how to make the fun map last night.
