smokinduc Posted December 14, 2007 Share Posted December 14, 2007 Maybe this has been brought up before but.... Wouldn't it be nice if someone was able to convert the silly vacuum MPG dash gauge on the LGT into a boost gauge? I think it would be quite easy. The manufacturer could also develop a stick on overlay with boost markings. That would be easier and cheaper than a complete new dash face Link to comment Share on other sites More sharing options...
RaGe Posted December 14, 2007 Share Posted December 14, 2007 this will go nowhere and it will go there fast. OTM. Sorry I didn't mean to start a war which mainly forum people is all about . Link to comment Share on other sites More sharing options...
TPLGT Posted December 14, 2007 Share Posted December 14, 2007 ^^^Why so negative? There are some smart MF ers on this site...look at Jazzy MT...engineering that was rediculous. I am sure someone can do it! Rehab is for quitters. Link to comment Share on other sites More sharing options...
RaGe Posted December 14, 2007 Share Posted December 14, 2007 cuz there is already a vac line to tie into. be the lab rat then. lmk how it goes. OTM. Sorry I didn't mean to start a war which mainly forum people is all about . Link to comment Share on other sites More sharing options...

However, it is in the very early stages as I am still gathering materials. Link to comment Share on other sites More sharing options...
taskforcefreddy Posted December 14, 2007 Share Posted December 14, 2007 Someone correct me if I'm wrong here but I believe the MPG display is based off of injector duty cycle as opposed vacuum. I say this because after upgrading my injectors, it threw off my mpg reading and it now reads a real high mpg. Someone else elaborate please.

CzarDestructo Posted December 15, 2007 Share Posted December 15, 2007 Shouldn't matter, it's an electronic signal that determines the gauge read-out. All you need is a device that converts the vacuum pressure into an electronic value, then you need to know what the voltage range is for the gauge (and it's pins into the cluster) and weather or not it's linear or not (if its not you may have a bit of extra work on your hands depending). From there you just whip up a SSC (Signal Conditioning Circuit). It's very possible and potentially easy assuming the gauge itself doesn't operate off some wacky input.

You could do it more simply than this, even. Just remove the mpg gauge guts, take the guts out of a 1/4 turn boost gauge, and replace the former with the later. Done.
