Air Flow Meter Translator

It appears that the Air Flow Meter on my 1984 Maxima has gone bad. Taking a closer look, there appears to be a major restriction in order for air to pass thru the flapper door.

Rather than spead $400 for a rebuilt sensor, I would like to get rid of this restriction of air flow.

Has anyone found a MAF Translator that will work on our cars?

To clarify my earlier post...

I am not looking to buy another Air Flow Meter, rather...

I would like to replace my Nissan Air Flow Meter with a Mass Air Sensor from another make of car. For example, the Mass Air Sensors from a Camaro or Mustang have a much larger diameter than the air sensor used on our Maximas.

Has anyone done an engine mod using a MAF sensor from a Camaro or Mustang? If so, who makes a GM MAF or Ford MAF translator that will work on Maximas.

Get one from a z32. That way you'll have a MAF that's made for a high performance engine and still keep the Nissan logo.

you guys make it sound so simple...

if you go with a different MAF you will need some sort of ECU reprogramming to make this work...and even so if you don't have the mods to warrant this you are wasting your time and could easily go to the junk yard and get a replacement. flapper door style MAFs are the WORST!!!! my 83 Z has one of those and as far as upgrading to a hot wire...good luck, there is MUCH more involved than simply rewiring ti in.

Is it worth having to go through all the hassle instead of replacing the sensor? Think about that then decide, DA_MAX is right on this one...

Could you try using a 3rd gen one? It uses the same connection as a Z32 and it wouldn't be as big of a difference in flow readings so you might consider it.

To my knowledge there is no convertor that would be directly compatible with a maxima. The Z31 may have a similar setup. Look to see if any of them replace it with a more modern MAF and how they do it.

if he has the L28 motor with the flapper door MAF to swap to Z31 or Maxima MAF, he will also need a Z31 ECU, some distributor parts from a 3rd gen and a some knowledge to re-wire the system to accpet all of this. you have to understand that the MAF swaps on the earlier L26/8s with the flapper door MAF were MUCH, MUCH more complicated than on the 3rd and 4th gens.

indy: go take a look on the n/a or turbo forums on hybridz.org ...they outline the process for upgrading from flapper door to the Maixma or Z31 hotwire MAF on the L26/8 motor. its not a simple task, but very doable...but also a complete waste if you DON'T HAVE THE MODS TO JUSTIFY IT!

That flapper door opening is fairly small. I was hoping that someone had already found a way to solve this problem.

Someone suggested that I take the electronics from my Maxima's AFM and move it onto the body of a Toyota Cressida AFM. My guess is that any Bosch-style VW, Volvo, or Toyota AFM would work.

I bought another 1984 Maxima AFM, so I can obtain correct volts and ohms readings.

Let's see what the HybridZ folks have to say...

this is what the 280zx-t L series motor guys are doing

http://forums.hybridz.org/showthread.php?t=91250

I was planning to do this on ym own 280, but I think I will be going with an SDS system instead...totally eliminating the MAF and relying on MAP readings for AF control.

again I'm speculating, but based on your cars year, the similar flapper door MAF and L-series motor...I betting the SAME thing can be done for your car as it is done on the 280ZX

Adapting a 1984 300zx turbo/Z31 MAF and ECU to a 1983 280ZXT harness:

I like this option, except that I would like to keep my factory ECU and injectors.

This could work, this is a step by step guide to swap the electronics from our AFM onto a larger Bosch-style AFM

You can get larger flapper door MAFs from older BMWs. They're even fully adjustable.

Am I the only one wondering what the point of this is? If your car is unmodded or not modded enough to warrant the need to meter more air than the stock MAF can handle, why in the world would you go through all the trouble to "convert" it to another aiflow meter just to have a stock vehicle with a bigger maf...

I guess the only reason he wants to do this is that the flapper door style MAM are rather restrictive. Eliminating such a restriction on the intake would provide power whether or not it had a higher max flow. Our MAFs really aren't restrictive at all so the only reason to get a different one is if we max its signal out with too much flow.

If a couple of hundred dollars and a couple hours of work is worth 3whp then have at it.

The first generation Euro BMW M635, M5 and M6 still used that barn door MAF and they all made more power than any Maxima, and all 3.5 liter NA 6s to boot.

I understand that part, but my point is, why worry about the maf when its expensive and complicated and will yield minimal results at best. I'm sure there are other restrictions on an 84 maxima which are cheaper to get rid of, and yeild better results, and are much simpler than a convoluted MAF conversion. I don't pretend to know jack about 84 maximas, but I would think a Y-pipe or intake or exhaust or something would be a much more worthy mod than changing the maf because its a slight restriction.
