is there any AFM that i can put in place of the stock 3vze? is there any that is "plug and play" with no mods the wiring, etc?

still waiting for the MAF conversion to come out but in the mean time, i wanna look for a backup mod.

the supra afm can be modded to fit the 3vze but there are some mods...bumpin yota has it on his im sure he'll chime in later today

Someone used one from a Mazda MPV I'd really like to see how it works out, he said it worked with no problems. I'd really like to see the part number.

sorry to bring this bak from the dead, but i heard the you can hook up a supra AFM to the 3vz-e and get a good gain from that?

try EBAY

lol.

IIRC the Supra one works with the 22re not the 3vze.

I don't think so, I think to use a surpa AFM on either the 22RE or the 3VZE you have to swap the trace boards.

Jeff Mosk did this mod on his turbo pickup, and mentioned that the while the 22RTE and supra AFm both deliver the same amount of fuel, the supras voltages are inverted from the 22RTE's. I'm not 100% that the 22RTE and 22RE AFM's are the same, but I'd bet their still pretty close.

I think Ganoid did this mod too, try PM'ing him too.

I've tried this with a 5MGE supra afm and although there is some power gains, you need a decent fuel controller to make it work correctly. With a Split Second ARC2 unit I could not dial in the unit to run perfectly with the 3vze. The engine would either be too rich at part throttle or too lean at full throttle, if you don't mind killing your non-existant gas mileage than thats not really an issue. In order to get the 5M afm to run correctly the idle air adjustment on the afm must be drilled out and adjusted, spring tension must be played with, and you need to turn up the idle speed at the throttle body. I did try to swap the 3vze trace board but something didn't work out, I believe it didn't bolt in to the unit, only one screw mounted up. To get the 5M AFM to work like an OEM unit you'll have to use a programmable engine management system like the SMT6.

Wasn't the development of the MAF conversion halted as well?

en with afms on the 3slow is like finding a fat chick

just install this

Don't think that will work as a substitute for a VAFM in our trucks without major surgery.

xzyragon

it doesn't

Matt16

...insightful

Nashman00

yup works very well i was thinking doing it but the v8 swap is just so much better for me

i even have the unite here in a box and if you ere wanted to trubo it will do the job

maft pro have goten dsm/mk3 supra/buick people in the 10'sand 9's at the track

On the 22re an AFM from a 1982 supra is plug and play.

Nashman00

all it is doing is leaning out the motor that is all

you chould do this with a fule persure regulator

in less the size of the amf is that much bigg as in the flapper door

InternetRoadkill

That's not exactly true. The ECU will detect the lean condition and adjust the injector period accordingly. The larger AFM just improves the volumetric efficiency somewhat, but not anywhere near like a turbo would so the impact on the mixture is not really an issue.

Junkers88

Um, no. Both the vehicles I've done this to show improved throttle response and an increase in fuel milage. A lean condition wouldn't allow that and it'd probably throw a CEL code.

Nashman00

that's called running lean and no it wonte throw a cheak light just melt a piston or burn a vavle if ti is to far over the hill

Junkers88

200,000 plus miles on the vehicle. I wheeled it every weekend and once or twice during the week. Drove it to work every day. 10,000 miles so far on the conversion, still have all four pistons, valve adjustment is still in Toyota factory specs, compression is still within specs.

The ECU decides what is lean and what is rich and it adjusts. I didn't know that running lean equated to fuel milage and better response in all rpm ranges. Thanks for the knowledge.


You have no idea what you're talking about but I enjoyed the discussion.

Nashman00

dude you on the fine line it has not blown up nore melted

that is where you are getting you power from a leaner running motor

what you air ratio is i have not clue my guess would be 17 maybe who knows

you all so have knock sensor in there to kick down timing to prevent pinging as well


every car that is made is made to be dumb proof reliability factor like at full song you car runs a 10 ratio or what ever

you have not taken this ratio and changed it this is were this power is coming form cause you afm tells the ecu what the hell is going on now if you give it hole bunch more air the ecu has not clue that you just fooled it and will keep on doing what it is doing

i have ran a dyno for some time and tune cars/trucks so frankly you the stupid dork this time around


more air and perfect balance of fuel makes power witch makes heat keep the heat to proper temp to stop perdetonation
