Anyone in Central NJ to help troubleshoot an SR20DET?
Just seeing if anyone is around in Central NJ that wants to help troubleshoot an SR20DET setup? Its driving me crazy! Was running perfect, MAF got water damaged, Replaced MAF and now she still doesn't run correct.
Since replacing MAF she will rev perfect in neutral, But falls on face when any load is present.

- Replaced MAF ( THATS IT ) bad maf again?

There are no codes, Have OBD USB Data Cable + NIS Data Scan as well as a wideband / Fuel Pressure gauge etc.. No codes.

Bad FPR?
Bad MAF Again?
Bad Walbro ?
Bad Fuel Pump Relay?

Car was running perfect, Parked for 2 months and MAF took in water and was replaced.... Thats it!
Anyone who is around I will feed, Serve Beer whatever lol Just want to drive my car again and banging my head against the wall..

I could not get my Nissan Data Scan to work yesterday but was able to use OBD SCAN Tech ( NISSAN )
Download App - [url]https://mega.co.nz/#!X5gCRZTZ!QzTWKPmnhl1bu_UcmX68l4QmMPR_SYNhD3b06Ep XNW0[/url]
Logs - https://mega.co.nz/#!D1A1CKCA!GVokAsyXr1IsjwdF8OxXnnKJuCTT-lRThO89lez2hUc

In the .zip there is 3 files ( Pull = Accelleration / Idle = Ideling / Drive = Casually driving )

I also made this quick video showing the car revving / some vitals etc, You can see it revs and idles fine..
But in the end you'll see it leans out when you rev and the wide band goes randomly rich for no reason as
well..

This is all kinda what it did when my fuel pump died a while ago, Now has a walbro 255 with less than 8k miles on it.



Ill get better logging with Nissan Data Scan asap but hopefully this helps a little, If i get on the gas hard it
it goes like it wants to and then falls on its face lean / breaking up. ( obviously I dont do this long at all only troubleshooting ).

This tune and car setup has been running perfect, Car sat for 3 months The MAF got damaged ( water leaked into billet box ) and was replaced thats all..
Doesnt seem to be MAF related though. No codes was getting MAF errors prior seems fuel related but im out of ideas besides FPR or PUMP or PUMP Relay

Thanks in advance all!

Seem like a bad pump? Thats what im leaning towards... Its acting just like when my stock pump gave out.
Does Aeromotive make an in-tank pump for our B13s?

yes believe they do make a pump for our car.

sounds like a pump to me had this happen in another would go lean once in boost up top

Cool im seeing the following options for our cars ( leaning towards Aeromotive )

  • Aeromotive 340 Stealth In-Tank Fuel Pumps
  • AEM High-Flow In-Tank Electric Fuel Pumps 50-1000
It appears I need a kit regardless to use with a B13, Boy do I miss driving this car
