There are mods to reduce the mass (lighten) the VAFM & reduce the spring rate... helps somewhat with throttle response.

 

I had an extra airbox lid to hack up so I just enlarged the bolt holes and I cut a small tab off of the airbox to angle it up to fit the new AFM(the one from the camry is a little taller) and used super glue and epoxy to hold it together, then RTV silicone to seal it all up.
I also had to buy a new 3"-3" coupling to fit the ISR mod. It looks okay overall i guess

 

Looks okay... I guess the best idea would be to get the camery vafm and an extra 3vze airbox to mess up...

 

For those of you that have done this, are you still happy with it?

 

Just wanted to note that gasoline engines run stoich (given amount of fuel for a given amount of air) at partial throttle settings so an MPG increase or decrease is unlikely from this mod alone. Where it should help is at peak power demand where it would allow more air to flow. It may also improve throttle response.

Can anyone verify the 10 digit part number on the Camry AFM?

The one I have is 22250-62020. Its listed as a 87-90 and 91 Camry 6cyl AFM.

I grabbed one today, and will try it, but just want to make sure of a part number for guys to reference.

 

I just went and double checked mine, it's the same part number you posted.

For the record I have been running mine for about 2 months and see NO INCREASE IN FUEL MILEAGE ya the throttle response is better and it gets better air flow but I think all in all it's not worth the time or money.
I will be adding a hydrogen set up soon like in a few days maybe that will help I guess we will see

 

so, whatever happened to swaycleveland? hes the one who started this thread, so, lets hear his outcome...

 

My AFM was $16. Its worth the $$$ for better throttle response and air flow to me.

 

same here, it has not increased my mileage at all

 

Never heard of the boy who cried wolf?

 

yea.. i ran it for a couple months.. way better throttle response and whatever, but it made my gas mileage worse by 2-3 mpg, and it wasnt worth the slight gain of acceleration to me..

 

That was more my hope from this mod. MPG increase would be great but I'll be happy with improved driveability and same MPG.

Thanks for the responses.

 

Oh great! I'll probably still try it if I can pick up a cheap part but I won't worry about it too much.

 

its worth a try. its so easy to swap in and out im probably gonna put it on before i go wheeling, just so i can have that extra response if i need it, but ive decided against leaving it on for every day driving

 

my imput is this........
after running this mod for a while now, i can say i still get about 300/400 a tank depending on how im running it. i drive all over ohio every week.
going up hills seems to be less of a problem for the truck after the mod
pick up is increased
gas mileage well i cant say im gaining anything
i think most was in my head and in my throttle response.
i paid less then 20 bucks for this thing so i think its okay but it wont be a 3.4



i also need to remind everyone im running a 3.0 AUTO with manual hubs and open diffs 4.88 gears and 285s (33s)
so ill never get awsome power

take it or leave it it was worth a try to open up the air way on this motor
the throttle increase was noticeable most will tell you.

on a side note i didnt start the mod i only started this thread (the other thread died before we could find out what the outcome was. and i did say id be back to let everyone know how it goes)

so for all you out there who used the mod hope things work out well
those that didnt i dont think you should bother unless you get one cheap

o2 note. i havent seen any evidence that im running lean not CELs
but i dont have any gauge to know for sure

good luck everyone

 

Personally, I think the main differences you will see are a 'seat of the pants' feel. Maybe because the 'new' afm responds more quickly and consequently signals changes in air flow just a tad more quickly to the ECU. So 'off throttle' response may be quicker. Other than that, I can't see it doing much.
The ECU takes readings from the coolant temp, throttle position and air flow meter (and intake air temp) sensors and calculates what to do, and when in closed loop mode uses the O2 sensor(s) to fine tune the mixture.
When in open loop / wide-open-throttle, you can only hope the TPS and AFM are calibrated correctly because then your only 'saviour' is the knock sensor.

 

a couple other things

first my apologies for leaving everyone hanging for a while this is my busy season and the next 60 days are gonna killllllllllllllllllllllllll me

i forgot one important fact
i drive my truck slowly i NEVER let the rpms get passed 2500 thats where i picked up the milage from try it sometime

anyway
it was worth the try

 

how about posting the actual miles per gallon? 300-400 per tank means very little. maybe you have a 40 gallon tank or maybe a 10 gallon tank.
various toyo's have between 13 and 17 gallon tanks so that 4 extra gallons could be 100 miles depending on the miles per gallon.
