Rb26 Pfc And Single Maf !

[stricnynel0s]

ok i have read paul33 faq and its my new power fc bible ! i had one question about it though, as far as using the power fc on a rb25 or 20 which uses 1 maf and one o2 sensor, and wiring them in parallel, has anyone actually done this ? i was going to start with 2 mafs and compare the voltage readings and if they were similar enough i was going to wire one z32 in, and the same goes for the o2 sensors, i was going to check if voltage was the same on both, and if close enough wire them in parallel and use the free o2 bung for a wideband on the rear turbo ! just curious if done yer or was i going to be guinea pig

yeah so you get the AFM Signal wire and run it to both inputs on the PFC for AFM1 and AFM2

under SENSOR SW CHECK you should see the same voltage for AFM1 and AFM2

the PFC uses an average of the two values for its load axis calculation

the SAFC will let you achieve the same goal

that is two AFMs on a single AFM ecu or a single AFM on a twin AFM ECU

if you are worried get someone who is an auto elec style person to do it

or maybe use diodes on the AFM signal if that will work ? someone could confirm this perhaps?

known in the wild is Cubes he did it on his R32 rb30det running BNR32 PFC

he is using a single Z32 from memory - The Mafia also did it when he got BCNR33 PFC working on RB25 with single Z32

how about o2 sensor same thing ?

[paulr33]

correct, same thing applies

run a single 02 sensor (narrow) and run its output signal wire to both 02-1 and 02-2 inputs on the RB26 PFC

under SENSOR SW CHECK 02-1 and 02-2 will show the same value

gotcha thnx for ultra quick response !!!
