Z32 Maf Probs

[gtir350]

Just had a go at fitting my Z32 Maf,

Prob is that its shows 3.03 Volts at Key, the standard Maf shows .5 Volts

When i try to start the car i get loads of black smoke, and it wont run
Is the Maf Dead, or have I made a common error when connecting it ?

you are over fueling,
are you running it on a standard ecu :?:

im not that stupid lol

im runnin the power fc ecu and set it for a z32 maf

check that the conector wires are the right way around as this will give the wrong reading.

Didnt mean to afend you but you have to ask the silly things first.

No probs dude, I'll check the connections, ( I prob am that stupid
z32 maf has 2 ground wire's , 1x12V-In and 1xoutput 0-5 Volt.

Look on the number on the MAF! It must have 30P00! other number are not run really on the power FC. See here: http://www.tomco-inc.com/Catalog/34mass air flow sensors.pdf there are all numbers from sensors. Yours i believe not for Turbo! Think Maxima...

It is a Z32 turbo Maf, 700cc Injectors, Turns out its could be the instructions in the "How To " is incorrect ?
As I found another set of instructions, and the two orange pair, were back to front.

Now all working fine
And sound Very nice with the bigger intake pipe run .

, Thanks

dont forget to adjust the injector % and lag time for your injectors otherwise your base map will be way out.

Thanks

Glad you sorted the problem ,

so which are the right fitting instrucitons for the z32 maf?
are the instructions on the "how to" any good?
i also found another set of fitting instructions, which is a bit different!!
the one posted in the "how to", coonect the 2 ground wires toghether, while the other instructions i got they run one wire to the harness ground, and another to a chassis ground

which is the right one?

i connected the cable with the crimp eyelet to the chasis and the other earth cable to the orginal loom on mine worked fine.

Thanks
