AFM

[ignigknot]

Well i just took the KA engine out and realize i still need a afm. Anyone have one hanging around i can get?

[onevia1800cc]

i think you can wire a ka maf to work with the ca?? i think i read some guys posting on it awhile ago?

[ignigknot]

ooo didn't even think about that.

[c-rad]

......as long as its the SOHC maf.

[ignigknot]

ahh crap no its the dohc maf

[onevia1800cc]

hmmmm is there a gain??? i have a sohc one

[pulsar gtr]

No, there is no gain, except with the Ka24E MAF you don't need to retune the ecu to get it working as it maxs out at the hp as the ca18det.

I believe I posted the maf hook up in one of the stickys a long time ago, check the stickys.

I found it in the sticky

coolis that why the 24e maf doesn't have that adjustment thing you have to use a probe of some sort to use adjust that thing

[knightrider]

what adjustment on the maf? there are no adjustments available on any nissan mafs, if your talking about the pot on some mafs, that doesnt adjust the voltage of the maf, it accually has nuthing to do with the maf. it changes a voltage inside the ecu, but doesnt affect the a/f or maf in any way

[biosehnsucht]

you could try finding a ka24e maf locally from a junkyard or such, probably easier than finding a ca18det one on short notice

or get your choice of other MAF such as Z32 and either repgoram ECU or get a SAFC, but I'd say just get the KA-E MAF for now

yes the pot on a stock ca mafsi have no idea what it does the fsm says to use a probe in the exhast to adjust, if the probe is in the exhast how does that control or adjust only voltage??the probe has to be metering mixture not voltage

[float_6969]

It's for adjusting emmissions. I'm not at home, but I've got a PDF file that explains it.

ok since i had both a kae and a ca maf handy i checked them both out and the ka one is definatly bigger. now what i want to know is will it hurt things if i use the ca sensor on the ka housing as the screwholes are exactly the same will i need a retune??

[WeldingHank]

i only used a KAE maf on my CA18 when i got it. with no tuning what so ever. i still have my KAE and my stock CA18 MAF hanging around for anyone interested.
