Do you have the blow off valve dumping back into the intake or did you ricer it out by letting it dump into the atmosphere?

Lol have it going into the intake

Check for a vacuum leak, a broken hose or lose intercooler piping clamp. How many inches do you pull at idle? 15? 20? on the boost gauge.

Ok ill have to look around, It's pulling 15 at idle

Yeah you should be at least 19-20. You can build a tester at home depo. Google it and you will see what you need. Make sure to disconnect the PCV from the intake manifold to the valve cover when you do and don't put more than 5-8psi into the system.

If your ECU is stock and not running a SAFC thats setup for those MAFS then you are using the wrong one.

Stock RB20 MAFS are J60's

Yellow4g63 · 06-03-2012, 10:55 AM

You can run the N60 maxima maf in place of the stock. The VQ maps are dead on with the factory maf. I think the S2 RB25 uses the E60 pink label one. Even that one is pretty close too lol.

Anyone got proof? voltage checks?

I just dont believe Nissan would would develope Two MAFS that produce the same Voltages just to use a diff connector.

I am running stock ecu, Do you know where I can get a j60? Lol haven't seen one on here
I've heard the n60 would work to? That's what's one there now

Sileighty_85 · 06-03-2012, 04:20 PM

You can search on Nico in the RB section it's well known. Also I changed the rom on another car I tuned to run the RB20 maf. I bought the N60 maf and plugged it in and didn't have to change the VQ map at all. It fired right up and got the same A/F reading as before.

247_c2c · 06-03-2012, 09:09 PM

Update I just found two kinked hoses and when I unkinked it the car idled high and then went to normal so in thinking its not getting the proper air flow when coming to a stop

bigheadJswag · 09-30-2012, 08:52 AM

I have a similar problem too man.. PLease kepe us updated and about the rb20 maf as well, if you ever get one let us know is it has positive effects..Thanks many
EDIT: Sorry, but anyone know where you can find the connector/pigtail for the rb20 stock maf?

247_c2c · 09-30-2012, 09:31 AM

Well I don't have the rb anymore but I did end up fixing the problem... The previous owner did a shitty job with the swap and had a almost every vacuum line leaking so I stopped the leaks and it fixes the problem
