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
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

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

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.
