But will have to reflash my ecu.

yes have to reflash it ..it you havent maxed the cobra out yet,(350Whp) then stick with it until you hit the point where you must change to the z32 maf.. and then reprogram it..

does anyone know the part number of the RB20DE MAF

LaRocca Racing · 06-16-2006, 02:20 PM

These MAFS measure 80mm in diameter and utilize 5 pins. The part number on these units is 22680 02U00 A36-000 J60 and are capable of just over 300hp.

These are just dates not partiular to a chassis but just for engine since I dont think very many here are running RB series in the car if you are and you wanna know which MAF goes with what ECU I can look it up for for specifically.

RB20DE(T)
Part # 22680-16V00

RB20DE(T)
Part # 22680-02U00

RB25DE
Part # 22680-02U00

VH45DE
Part # 22680-61U00

VH45DE
Part # 22680-61U01

VG30DE(T)
Part # 22680-16V00

if u got a apexi safc 1 and u swap out the maf and tune it on a dyno will u still have to redo ur ecu, or will it be ok with the safc..

i got a j30 maf

and i got acess to cobra maf and alot of nissan mafs

because i worked for nissan for 8 years and i now work for ford

with this MAFs if i stick to a nissan one can i use my oem plug because ive not tried on my 93 se-r?

az-ser · 07-07-2006, 12:16 AM

if i have a 96 b14 with stock ecu and maf///can I put a bored out 99 se-l maf sensor on it??

stock is 3 bar. Only an aftermarket tune is going to run 4 bar.

Walker · 07-29-2006, 03:47 PM

thanks for the info i guess i'll just have to get that four bar programme from jwt.

Sigfod · 07-31-2006, 08:59 AM

This is awesome I can use my stock MAF and make the HP I want to.

Thanks for the info.

which part a monbay you from walker?

Sigfod · 08-09-2006, 07:41 PM

Ok I have a GTi-R motor going into a B15 Sentra SE equipped w/ an SR20 DE. Can I program the GTi-R ECU to use the B15 SE MAF? If so how much can I make on a stock turbo in that thing w/ a 3" TB and a FMIC using a Walboro Fuel Pump? Thanks for any info.

i have a de- with de-t pistons, have 370cc jimwolf program. is there some where or some one have a 444cc 4 bar with a bored out 54c program that i could purchase. i have injectors, fuel rail and air flow meter. interested in having approx 300 whp

Whay year car do you have or which model car do you have.

sammy · 08-16-2006, 03:30 PM

1993 SENTRA SE-R

venom2727 · 08-20-2006, 10:15 PM

hey i am new to sr20 and was wondering how the calculation goes with the maf sensor, is it that the maf sensor measures the hp or the air. i want to do a turbo setup but i want to know if my maf sensor will handle up to 20 lbs of boost or i will have to get an aftermarket one i guess i am not too clear about the hp how it relates to the maf sensor with regards to the amount of air that will be going into the engine from the turbo.....anyone out there can explain this to me please.

Here is a simple explanation:
The MAF sensor sends a voltage signal to the ECU. The voltage signal changes with air flow - at low air flow volume the voltage is low - conversely at high air flow the voltage rises.
Nissans uses a 1-5 volt reading. There is a "hot" wire located in the MAF. It is this wire that changes the voltage reading the computer sees and thus uses this data to change the fuel flow in percent of duty cycle (how long the injectors are open per spray).
To keep a turbo motor happy, you need to make sure you are not flowing more air through a MAF than it can register withing the above stated voltages, and you need to "see" what the duty cycle is for your injectors. There are lots of very knowledgeable folks on this forum, both past and present who have covered this topic with reams of good information and thousands of posts.
I knew nothing about turbo cars, but before asking the same questions that have been coverd for years, I simply read and read.
I now have a very dependable ride that is very fast - and I've meet my initial goals and know where to draw the line and be realistic about my "dreams" versus reality.
So if you still don't understand all this stuff, as many here say - search and read - then ask those specific questions you REALLY cant find an aswer to.
Best of luck in what ever you choose to do.
