interface to a pc
interface to a pc
Hi, anyone know what would be involved (hardware/software) in getting the ECU and possibly the (auto) transmission controller interfaced to a PC laptop running windows or something. I am thinking of wiring up a laptop in my mx-3 and use it to monitor the engine and transmission during normal day-to-day driving. Any info is greatly appreciated. Thanks.
Hey thanks for the reply - i looked into megasquirt before and it is promising - but i want something to just monitor the parameters and not control anything - definitely not fuel injection - i say that because i beleive if i start screwing with things like that the engine might just blow up one day or something. So i just want to monitor whatever data the ecu is sending out and maybe build a custom software to display a second set of gauges on the computer screen - i am also thinking about a custom mpg gauge by monitoring ecu outputs.
Does anyone know what protocol is used by a 94 mx-3 1.6L 4 cyl DOHC ecu - OBD1 or 2 (ISO or KWP or J1850) or something else altogether. Thanks.

I found this link - http://cable.invisibill.net/
it has info about how to make a custom cable to read data from ecm into a computer - we would still need some software like datamaster or freescan or something - if we could get some data sheets to make sense of the data that flows in we might be able to write our own software - but this is the first step i guess

These guys have readymade cables for obd1

Sounds like a good project. There are a few custom ways to gather info. The easiest way is to use the ECU data port coupled to the PC serial port. The other method would be to interface all sensors directly and develop a data aquisition circuit which can deliver USB, Parallel or serial data to the PC. The software can be custom tailored to the ap.

i tried looking for the data port in ecu - cant find it ....
looks like pre 96 mx-3s didnt come with a data port.

I don't think it exists. As I mentioned, it is possible to build a data aquisition circuit and choice of PC interface.brakecrasher wrote:Does Anyone know where i can find a usb interface to conect pc to the ecu or diagnostig plug?
BTW- Bella pagina del Internet!
