Quick update. Subaru ECU is made by DENSO. I quickly implemented a cheesy KWP2000 fast init style as specified here: prj.perquin.com and I was able to get a response from the ECU but the rest of the obduino32k.pde doesnt seem to work. I am suspecting timing issue but I am also wondering how those universal obd-ii works (timing wise) since they have to deal with multiple ECU from multiple companies...

I am using a serial LCD (softwareSerial).

I just made a quick test using the serial port and notice that the TX and RX light are blinking... but they are not blinking when I use OBDuino32k.... might be due USB vs No USB.

I have power but iso_read_byte() always return 0 so apparently there is no TX/RX. I tried swapping TX/RX but nothing as well. Anyone can help us?

thanx
