I got everything hooked up, drug my pc out to my car and hooked up the aldl cable I made. I ran Craig's Software in Dos and can't get it to connect. I get the flickering 00/FC values, but it won't link.

Does the ECM need to be in closed loop for it to connect? I left it up for about 15min and no luck.... any suggestions? Thanks Joe

I build that cable too and i am having the same problem as you. I can not get it ot connect. I pacd the 10K ohm resistor between A B and nothing. All I get is just that lickering as you do.

Can anybody help us out?

someone give me the schematic your using and the values of your transistors. drrizt2k1@attbi.com

Here's a link to the interface cable I made :
www.andywhittaker.com/ecu/aldl_hardware.htm I'm using the 2n2222a transistor and 1n4148 diode with the three 10k resistors and 1 10k jumping the "A" and "B" terminals exactly the same in the diagram.
