I am looking for something I read in a magazine this year. What it is is a 10 LED meter which is like a LED/digital vacuum gauge. The way it works is that at cruise or high vac. and easy acceleration it lights green. As your vac. drops it lights yellow and finally when vac is really low like WOT it lights red. Has anyone else seen this device? Help me out and and post where I can find one. Thanks. Cool site!
Well you can do it as a 5V LED voltmeter and bargraph hooked to a MAP sensor, or a 12V ditto hooked to an injector wire through a 330uF capacitor, or a O2 sensor mixture reader... ... ...
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
I found it mentioned on this site the Digital Fuel Mizer. It looks like a great learning tool and can return it for a full refund up to 3 years. How could you go wrong. I also found a 10 LED A/F meter but I need it to do 0-5v so it can monitor the MAP sensor. Thanks for everyone's help and a great site.
