    NON-OBD2 based gauge app?

    Hey Ive asked in a few different post but I figured Id ask in a dedicated thread.

    Is there any apps for gauges that dont require OBD2 to function? I want to use a Fusion Brain or similar device to read 5v engine sensors and then output to a user modifiable gauge program.

    Does anything like this exist? Personally I dont want to be tied down to only OBD2 data since there are alot of sensors that arent part of that data set. Things like fuel level, EGT, aftermarket wideband info ect. It would be really nice to just have sensors plugged into a dedicated controller instead of reading off an engine computer (if you even have fuel injection or if you have a standalone).

    If anyone can point me in the right direction Ill do the learning.

    Look up the Fusion Brain here on mp3car, it is capable of reading analog inputs. It would be rather simple to write a program to read that and display values on gauges.

    yeah I think the fusion brain would be great for that. I was wondering if a modified front end like RR could be used to display the gauges. More or less Im not a computer programmer so making an application isnt in my skill set. I am willing to attempt it but I dont know how successful Id be.

    I don't know about RR, but I'm working on a Fusion Brain plugin for CarPal which will display analog voltages as radial gauges and the like.

    Depends what you are running, I am using Megasquirt and there is an app that displays all the various dials you would normally get, on the pc just using the normal megasquirt comm port

    Heres the plan at the basics. For the sake of simplicity assume you have an old car, no fuel injection, on board diagnostics or any other computer controlled sytems from the factory.

    The plan is to be able to go to NAPA or whatever parts store and buy engine sensors such as a coolant temp sensor or air temp, oil pressure ect. Install those into the engine and wire them up; sensor ground, sensor voltage and sensor return. These sensors would be hooked to a Fusion Brain since this seems to be the easiest way to feed the raw data into the computer. From there the software will create the gauges and display them on the screen.

    I came up across this in Google Code which is pretty damn interesting and Im hoping maybe someone on here with knowledge greater than my own would maybe be able to give me some help on making the two talk to eachother if at all possible.

    heres a link to the code page http://code.google.com/p/memefx/wiki/gaugeintro
