Auto ECU read and control

[jgemelli]

I am looking to build a box that will be able to output all of the information that an automotive ECU is provided. If possible I would like to be able to alter the information as well to maximize fuel economy and power. Does anyone have an idea where I can start to look?

Thanks in advance.

BTW I have cash to invest in this project but not a ton. $3,000 dollar machines need not apply

hi ,
From your query what i understand is that you need to have a multi-mode engine management control in your car..alike sport-city-eco mode like wise.....one user friendly software/ecu kit i have come in wintec from <

http://www.getfuelinjected.com>where

you can download their free software and manuals in .pdf format.
In this you can programe different map values and store it in your computer..later switch of the engine and load the required mode file ...then crank and drive....there are still some co's whose software is compatable with palmtops..and one final thing plotting map values with a dyno and flow bench will help u a lot ,also time saving...hope this message helps you ...

Thanks alot!
I saw the website and find it to be very interesting. I am still looking to do a custom computer that can be had for very little so I can offer it to folks who like me want performance and the ability to monitor their cars but don't have a lot of cash.

I may be able to use some of these programs or ideas in this endevor.

you could look into doing it the way I have been trying and design it into a standard port such as PCMCIA or USB so that most of the processing can be done on a laptop.

hi sir,

i dont know if i understand exactly whats going on, but i have been for a long time looking for some diagnostic software for bmw so i can connect the laptop to the diagnostic socket of the car and have full acess to all the electrical parts of the car (control unit, sensors,...)

i would be very grateful for you if you just inform me from where to start

thanks in advance
