That looks exactly like the MAF on my 1991 XE. Are you saying that that screw adjusts the readings?

The question that begs to be asked is why do you want to adjust your air / fuel mixture ratio at the MAF sensor? Are you building a turbo car or something?

If its anything like my Z31 MAF, there is a plug that covers the screw from the factory (to keep people from tampering with it). Drill it out to access the screw.

Why do you need to adjust it?

After doing some research and please correct me if im wrong!!

Stock air fuel ratio is 14:1 for Ga16DE @ IDLE Im Not sure what stock a/f r is at WOT

optimum ratio after adjustments is 12 to 1 @ WOT

Im working with Hydrogen and would like to get the best air fuel ratio before implementing HHO.

99% of the questions that are "STRANGE" have a dirt simple answer...usually answered by a dirt simple search.

NISSAN GOOGLE

Is it just me, or does the majority overlook the obvious?

Somebody ate a whole bag of dumbass for breakfast.

Why do people continue to run a vehicle when a warning light comes on or starts flashing? Isn't that a clue that something is wrong and you probably should NOT drive it?
Is this whole car driving thing really freekin' brain surgery?

Here's something new for the crowd/clowns...
"A little bit of Google goes a long way!"

Ever notice the one post wonders for info on turbo'ing a GA16 are never heard from again after they figure out the cost???

And if you can read this, you don't need glasses! :)

And yes, I am diggin' it...

No...no...no...I can't. I couldn't.
A) I'm laughing too hard.
B) No genius-ness required. In fact, quite the opposite. The thought alone speaks for itself as to how much genius-ness is required. Have you thought about a reality show?

This is surely one of those cases where YOU have GOT provide the rest of the world with your great insight on how hydrogen will save everything...or how nitrogen in your tires will make everything ok...or how magnetic wrist bracelets can cure all that ail you.

Ok. it is a proven fact that Hydrogen is combustible eliminating extra fuel and harmful gases in your air intake ect ect. You have yet to say anything inteligent - so honestly f off.

Ignition
Main article: Minimum Ignition Energy

"Hydrogen-air mixtures can ignite with very low energy input, 1/10 that required igniting a gasoline-air mixture. For reference, an invisible spark or a static spark from a person can cause ignition."
"Although the autoignition temperature of hydrogen is higher than those for most hydrocarbons, hydrogen's lower ignition energy makes the ignition of hydrogen–air mixtures more likely. The minimum energy for spark ignition at atmospheric pressure is about 0.02 millijoules."

I'd suggest some sort of wideband before tinkering with WOT fueling.

Good luck getting anyone to take an HHO project seriously. I'll refrain from arguing with you, just don't expect to gain anything from it.

Good luck with an HHO Project. I've a Bachelors in Mechanical Engineering and I wouldn't waste my time. Just turn the car into a hypermiler. Buy a piggyback fuel controller (SAFC or similar), and adjust your air / fuel mixture ratio that way. Much easier, and in conjuction with a wideband, much more efficient. In my experiences, though, just don't f*ck with the factory settings unless you've a really good reason for it, i.e. forced induction.

P.S. Hydrogen is the most flammable and combustible element in the world, so not only do you have the problem of obtaining hydrogen (whether through purchase or "creation"), but also storing it properly. Remember the Hindenburg?

***AT THIS POINT, PLEASE DO NOT POST UNLESS YOU KNOW exactly WHAT YOUR TALKING ABOUT*******

Please don't throw your degree into this discussion, Its obvious how American colleges have done a piss poor job on science education.

First
1. Does anyone know the Stock air fuel ratio of the Ga16de at Idle and WOT ?
2. Does anyone know the optimum air fuel ratio of the Ga16de at Idle and WOT ?

Why would i buy a SAFC if i can control air fuel ratio by turning a screw on my MAF. Dont worry ill have a couple to test on!

So far the best information ive got from this post was " there is a plug that covers the screw from the factory (to keep people from tampering with it). Drill it out to access the screw."

Oh by the way HHO gas by weight has 3 times the explosive power than gasoline. For this reason it is unstable and not safe to store (when mixed with oxygen), for this reason we produce it on demand. But HHO is MUCH safer than gasoline, gas when spilled is heavier than air and will collect at lower areas. HHO gas is lighter than air, and when "spilled" will dissipate very rapidly in the atmosphere, without poluting, chemicals or toxins.

I'm not going to even bother wasting my time to further your pursuit of indifference.

For some reason we are quite good at this thing you called science. You might recall Sir Isaac Newton, Brunel, Watts... need I say more? Also, I earned a 1st from the University of Bristol. Just letting you know some of us aren't exactly uneducated.
My apologies. your right. i just wanted to get some answers but everyone wanted to pry into my business...
