Hi guys,

 

My Zed is an Jap import and came with an Air Flow Resetter (I was told that it was an Air Flow Controller but it is labled as Air Flow Resetter) which has an on off switch and a controller...

 

I googled all around and only got one hit from a forum saying

It changes your AFR reading by fooling your maf into thinking it's getting less air than it really is.

but it is not confirmed.

Can anyone tell me what this is and what it does?

 

Mine is a N/A and I was told by Legrath in another thread to remove the Air Flow Controller since I have no advantage of it and will be causing running problems.:bow:

 

Legrath if you are reading this is it the same with Air Flow Resetter? Could you (or anyone) please give me more details on what this Air Flow Resetter is and is it just enough to switch it off if I want to remove it...

 

Thanks

if thats what it does then it will be for exhaust popping or maybe making flames as its basically telling your car to overfuel

I do get a slight exhaust pop sometimes but I thought this is normal with a Zed... please correct me if I'm wrong. Haven't seen any flames though lol

 

I'm no expert but logically less air means less fuel to keep the AFR, but in reality it is getting more air with less fuel (I don't know whether this is what you meant by overfuelling, sorry) obviously changing the tuned AFR in the combution chamber. I can't think of any performance advantages but with less fuel you could be getting an economy advantage with the price of power. May be this is because of the different fuel used in the car. And since mine is a Jap import this thing is fixed to use it with UK normal fuel. Please correct me if I'm wrong...

 

By the way I started looking into this coz I'm getting feeling a power loss at lower rpms. Still haven't put my zed into a datascan or a conzult but hoping to do soon :)

 

Then again... is that what an Air Flow Resetter is doing? :rolleyes:

Sounds like those Ebay 'black boxes' that are just a resister to change the MAF reading and fool the ECU.

More googling resulted me with

tweaks your AFM readings to trick your car into thinking its not drawing in as much air, i.e. leans out the fuel mixture thus increasing power.
which I found in this forum. The discription of the resetter is exactly the same as mine...

 

Can this be true? Can you get more power with lean fuel maps?

yeah, but you also get engines going bang! Just remove it and tune your car properly!!

Thanks Rich666, surely will be removing it....

 

I just wanted to confirm what the heck that thing is and what it does and I thought you get more power with richer fuel maps. :smash:

 

I also found this link,

It doesn't look like the thing in my zed but has the same name :)
