boost gauge idea (other post messed up somehow)

statedawg · Nov 13, 2003

ok before we flame i was just thinking (i know thats dangerous) to see what others would think... what if your boost gauge had a little shift light with it... im not talking about something huge like on them 8" tachs, but a little red LED or something... i mean if a big ass tach can do it why not wire up a little red LED right by your Boost gauge just for a little conveinece feature... if its too much work to be practicle then F it... but if its doable and not too expensive i would not mind having one...
in some ways i think this is a good idea, but then i think some more and it seems kinda useless/retarded... it might be an advantage if you had creep... and if you just like having cool gadgets...

If its an Electronic Boost gauge, all you would need is a POT, a LED and some quality time with a multimeter to figure out what exactly the MAP sensor is sending. if its a Mechanical gauge, then youd need the same thing, plus youd have to tear the gauge appart, void any warentee on it, and probably ruin it.

______ to ground

o----------P
O---------|------ to signal

O= gauge
o=led
P= pot

of course you'd need to find what kind of signal the map is sending first to decide what POT and LED to get (Id assume its a 0-5v setup on most) and you may need a nother resistor between the POT and the LED, again, depending on what the signal is like from the MAP.

Some electronic boost controllers have this feature.

It's probably very easy to do with a digital guage, much harder with a mechanical boost gauge.
