Project OBDuino - Control Temp's, MAF, % Load...
 

Hi People,

I am newbie at this and would like to follow my project which I quote:

I have a car, Seat Ibiza TDI FR at 2002, and have more power that OEM, so i need to be more careful with the pressures, temperatures oil, air. I don't like gauges of boost pressure, oil temp, more and more because in my view are Tuning and the Police are very restrict in my country. I decided to buy a kit # 1 Arduino obd.arduinodev.com, show the information in a small display. The person who sold me this, say me this interface work's with ISO 9141-2, but this chip only works with Can-Bus, because in circuit board are a chip MCP2551.
Weel, so i have a Arduino Nano and a small display i decided to make an interface to communicate with the protocol of my car ISO 9141-2. Started the construction based on scheme [Port DB9, Resistance 510 OHM, Tension regulator 12V to 5V (LM7805) ], and a cable OBD to DB9, for ISO.

Well, here is the story how it started, now comes the worst part and where is my problem. The kit that i bought, there is the libraries and source codes ready to works with interface with chip MCP2551. But, where is the codes to my interface? I found a source code that works with your scheme, but, i dont have the buttons and the lcd they used, it was a bit difficult for those who are ignorant of the subject of programming.

Hey guys, do you want help me?

I really apreciate your help and sorry for a long story smiley-sad

Regards and Thanks,
