MAP KIT
Mike,
I just finished the install on the adjustable voltage regulator to feed <5V as needed to keep tuning things for better mileage. ANYHOW as I look at your super nifty EFIE cleanly mounted on the center console I can't help but think that you could offer this clean unit as a MAP package of some kind. It would be near perfect, the friction holes for the meter probes while you adjust the voltage and a dual switch that turns the unit on when you switch the MAP to the units power or back to the ECM when the unit is off.

Should you make your fame and fortune from this grand idea please remember me and maybe mail a prototype kit version for field testing!

RE: MAP KIT
That sound familiar. I asked for a version of the EFIE that was dash friendly and also proposed to test it.

Haha. Once I make my fame and fortune, I'll forget ALL the little people who got me there! Laugh

I've been planning to do a MAP unit for a while. I hadn't considered a MAP Deluxe, but I guess it makes sense.

I will do something with that idea. Thanks.

RE: MAP KIT
Been driving for a few days with 4.8 volts being feed to the MAP and all runs well and no CEL.
BOY ( hint ) it sure would be much ( hint ) easier to have the regulator in one of those cool ( hint ) boxes like the EFIE so you can adjust the output on the fly with ( hint ) your multimeter probes being held in place for you. ( hint, hint )
I have no idea how far down I can go on voltage but a CEL or crappy performance are the only hints I have to work with at this point.

RE: MAP KIT
Hmmm. I think someone's trying to tell me something... I wonder what it could be... Confused

RE: MAP KIT
Here are a few pics of the one I built today. Only problem is I can only get it to turn down to 5.24 volts. I used all the part #'s that are listed on the tuning for mileage.
Is it possible to just put a variable resistor inline, one with a knob that you can just turn to lower the voltage a little at a time?

Thanks
Regards
Zeek

RE: MAP KIT
Well the electronic fairies must have come here last night as today when I started to look it all over and test it again, it works fine! I am not sure if I had the power to it hooked up backwards or what but it is working anyway.

I set it to 4.8 volts and installed it inline on the 5volt power line that goes to the MAP sensor. With a flip of the switch it will go back to the original voltage from the computer. Anyone have an idea of how far you can drop the voltage to lean out the AF ratio?

For right now it is installed under the hood and we will see how well it helps out with the MPG. If it does make a difference for the better I will go through the motions to mount it in the cab of the car.

Regards
Zeek

RE: MAP KIT
Generally you see about .70 volts at idle(high vacuum = lean) and around 5 volts (low vacuum = rich). I would guess if you could lower the 5 volt input voltage by about 15 - 20 percent might work.
