    Yes understood...serial port and 1 transistor cable works all day everyday. To re-iterate...USB, FT232 cable to winaldl is what some of us are after. Or should I say just get tprt...

    Dang. Another forum to decipher lol. So it seems I did not find the info, until now, that says the FTD232 won't work on the 160 Baud. So should I explore TunerRT or get a different board to work with WinAldl ? Is there a better program that I should use ?

    All I am really after is some data logging and/or reading real time info so I can figure out this crazy intermittent problem I am having. After the remedy I want to explore tuning and prom burning but, if I can't figure out this issue, I'm going to switch heads, intake, cam, and slap a carb on this thing. I'm not real keen on a computer controlling my engine but, I like the idea of having the ECM monitor and correct the air/fuel ratio. It would be a first for me as this 1990 is the newest vehicle I've owned.

    Guys I've got a strange issue that I've never seen before.

    I killed my old DIY ALDL cable that was great for about 4 years by soaking it in coffee and then accidentally sending it through the dryer. Had to order a new FT232.

    with the new FT232, if I leave it plugged into the ALDL socket but don't have it attached to my phone, the FT232 still lights up. I've never seen this before. I assume the ALDL socket provides power, but my old cable never lit up showing power when attached just to the socket.

    Can I fix this with just a diode on the ground wire?
