ok guys I just got back. Sorry I have been busy sending personnel to help with Katrina relief. But I called and left a message 5 minutes ago, so I should have an answer by tomorrow.

Let me know if there is still any need for a 1st gen donation. I'll be glad to let them screw with mine for a couple of weeks. It has the NWOR tri-Ys and K&N already, so it isn't stock, if that's a stopper. Sorry I didn't know about this thread before....

Just got off the phone with Josh and it looks like the R&D phase will happen if there is enough intrest from you guys. I will provide the donor truck.
I will post more details tomorrow, have to head to work now.

I have an idea.....
I have no idea if anyone tried this method or not but here it goes. Our VAFM meters (22RE & 3vse) use a door with a variable resistor to tell the computer an estimate on how much air is coming into the motor. Well since the door works on throttle vacuum, lets try this:
Make two seperate air intakes that go into one, sort of like a "Y" design. The VAFM just needs the throttle vacuum to open and close the door so "Y" off one side to the meter with a filter and then use a straight piece of tubing to go just to a filter. The VAFM is just a signal to the computer and all it needs is throttle vacuum. The other pipe will feed the motor with zero restrictions sort of the MAF mod without the tuning aspect. As I can see it, as long as the VAFM is getting a good throttle vacuum signal, the computer will not know. This will change A/F ratio and you can tune that by moving the arm in the VAFM to lean it out or richen the mixture.
I haven't tried this yet but this could work for all the VAFM vehicles out their if you have enough variable to adjust the A/F ratio. Does this make sense?

p.s. I just thought of this in my head.

I've got a 89 3.0 pickup and I live near Beltsville if they need another donor. But I have other issues that need to be taken care of (head gasket) first. I'd also like to get some head work done during the HG repair and install headers/catback. If they can do this work (I would pay for the repair work, of course) and use my truck as a guinea pig, I'm all for it. I can leave it for as long as it takes.

HEY SRV1 has a good and very valid idea one that might bear taking into consideration. If someone in the club has a road worthy ginnypig that they wouldn,t be worried about if something unfortunate were to befall the motor. WE could get are collective minds together and come up with something that 1 would work with reasonable power to $$$ gains and 2 be readely obtainable through local or online sources. This is my idea i'm working on now i,m takeing a bilge vent blower and mateing it inline with a re-routed intake pipe kind of like a snorkel tube then mating it, to a modified stock lower air filter housing that i stuffed with a K&N filter if i half to. I will try to rig up a cable between the throttle assy. and the silly little door on the vain airflow assy. Kind of like a poor mans super charger only you won,t have to worry about spooling the engine up or blowing anything up (i hope!!)

SRV1 that won't work.
What you're talking about is an AFM bypass. It is nothing more than creating a very large vacuum lek on purpose. To get it to work, it requires a programmable piggyback to re-tune because it is not a linear change in airflow.
As rpm & air consumption rise, the amount of air that will bypass a MAF, or AFM rises exponentually. because of that, you CAN NOT use the AFM spring, and idle-bypass to re-tune the engine.
I set one up more that a year ago on my 3vz-fe lexus using my SMT6. Didn't do anything compaired to simply tuning the AFM with the smt6 in the first place.
