just curious... do i need an AFM for intake? or does it not really matter?

 

Not unless you have a speed density computer. Otherwise, you will need to retain the AFM.

 

How do you think the engine's going to run without it?
Do you know what it's for?
Do you think it would be there if it wasn't needed?
Do you understand how EFI works?

Have a read of this: http://www.autoshop101.com/forms/h20.pdf

 

 

The above car has an LT8, which is what we on the internet call a "standalone EMS". Just about every standalone EMS on the market uses its own speed-density system for engine management, and therefore the original AFM has no function and is removed. If your car has both the LT8 and the AFM, I would recommend that you have it towed to your local RX-7 performance shop for evaluation because whoever installed it that way had no idea what he/she was doing, and it is likely that there are major problems with the car. A standalone EMS is an extremely complicated item that should not be serviced by a novice.

I can't give you any information with respect to that car because I have absolutely no idea what it is.

 

wow... i didnt think that people would be so angry about this one...

i wasnt implying that i had one on my car, otherwise i would have stated so.
and i understand how a standalone works, i was just wondering why some cold air and ram air kits have afm's. J-rat is the only one who's post

and evil avatar- thats a 1980 rx7 10th anniversary edition. look it up. and i dont think standalones are that extremely complicated, that is if you know how to read a manual...

 

You'd think that little detail might have been worth mentioning in the original post.

Crap questions = crap answers

 

uh... 1980 10AE instead of the 1988 10AE? you do know that 1980 was still first gen for 7's, and would have been only a 2AE if mazda made such a model, which they didnt.

About the afm, its possible that it was left in as a switch to the fuel pump, altho any professional doing this should know enough to wire the pump relay to the standalone ems

 

lets just get some of this straight...

1. i never said my car had an afm on it
2. yes i know a 1980 was a first gen. ive been driving it for 3 years.
3. there is an 80 AE.... heres a pic for ya.



heres a close up of that..




so.. hows it feel to be owned by a 17 year-old? good huh? next time, do your research before being a jackass...

 

It celebrated 10 years of mazda being in the U.S. or some jazz. Rare car.

 

Your original post stated "do i need an AFM for intake?" Since it is not very common for a human being to attach an AFM to his/her mouth, one can resonably assume that "i" would apply to one of your vehicles. This may not have been your intended message, but it is how it was generally perceived. I hardly think it fair to complain about miscommunication when it is due to your own poor sentence structure.

Oh, I see, 80 10AE-FS means 1980 10th Anniversary RX-7 For Sale? Sorry, I am not up on the latest teenie leet speak that hasn't been in common use on this forum.

Silly me, I bothered to read his signature for additional information in an attempt to help him out.

Amen!

It may be premature to make that statement until you at least have the basic understanding of an AFM. The very small number of accomplished EMS tuners should give you an indication of the level of complexity.

No thanks, I think I will move on to something more worthwhile.

 

I had never heard of an '80 anniversary edition, and assumed that it was a typo, especially since you are posting in the 2nd gen forum, and there is a well-known 2nd gen 10th anniversary model that is commonly abbreviated as the 10AE. sorry for the misunderstanding (if it makes a difference to your ego, which it obviously does), and out of curiousity, what differentiates it from other 1980's 1st gens?

Also, if you come into a model-specific car forum when you own one of the cars and ask a specific question such as "do i need an afm for intake" without any details or info on the car to counter what we see in your sig, what assumptions do you think will be made?

 

evil aviatar - i honostly look forward to reading your updates... i love them. if you look at every "For sale" thread, what are the first to letters in atleast 80% of them... FS . but i can understand the confusion of me not spacing it out.

and i do have the basic understanding of an afm, i was just curious to know why some cold air kits have them and why some dont.

and on the subject of cold air, do you have much info on co2 or dry ice kits? as in is it somethin worth doing? or a possibly comparable item for a DD?

 

First rule of forums: We can't read your mind. The question you asked ("Do I need an AFM") is basically the same as the "Can I remove my AFM" question that gets asked regularly. Hence all the answers you got were the same ones provided every time. What you should've asked, so that everyone understood your actual situation, was "Do I need to install an AFM on my EMS-equipped engine?" Then you would've been hammered for not understaning aftermarket EMS's...

No "cold air kits" have an AFM. But some cars have AFM's, and some cars don't (hence the different kits), and some like yours have had them removed. These cars use the MAP sensor for the ECU's load input instead.
