hi

my airflow meter isnt working properly. i have tried to find a replacement but am having a lot of trouble.

is it serviceable? if not are there any other airflow meters that can be used instead?

any help would be great

thanx

In what way is it not working properly?

I believe the AFM from a 5-ME will work as a replacement for the 18R-GEU

the car wont start with the afm on the throttle body

when going it idles very rough and occasionally dies when revs are put on

i was given this test by another toymods member http://www.4crawler.com/4x4/CheapTri...tml#AFMtesting

i did them and none of the results were even close

Try one from a 22RE (RT142 Corona or RA65 Celica). I have put one on my 2TGEU, works okay - want to get it on a dyno and check air fuel ratios, but it should work fine.

alternative is just get a Megasquirt

Oh yeh, thinking back i used a 22-RE AFM with my 18R-GEU with standard ecu. It worked fine, although air/fuel ratios were a bit rich down in the lower revs. But its an 18R-G, they love to rev!
An EFI tuner should be able to adjust the spring tension slightly to remedy this tho.

on another note, i believe 5-ME AFM/coil/igniter all are compatible with the 18RG standard stuff.

As is the wiring loom.... Just cut off 2 of the injector plugs.

On a related note, does anyone know of a flapper-style AFM which is larger than the 18R-GEU one? I want to put slightly larger injectors in my 18R-GEU, and rather than tightening the AFM spring to buggery I thought it might be a good idea to use a bigger AFM. Does anyone have a 5M or 7M AFM they can measure for me?
