i made the max2332 version of andrews cable and it worked. surprisigly. but now a few friends want cables and i am tempted to try the two resistor theory as it will be way quicker. is there anyway to test these using the db9 and some program thanx guys.

i am interested in making a cable for my car, i am sorry that this is off the post but where did you find out how to make it? and how much did it cost? a link would be great. thanks in advance.

very simple actually, well one of them. the MAX is a complicated version, i will try and find the links for you. cost was about 6 bux, but i didnt get the OBD connector. i just used 3 pins

If you are asking if there is a way to test the cable, just read your pcm. If it reads fine then go a head and flash it. If you are saying you are just using 3 pins plugged into the port then i think you are asking for trouble. If one pin falls out during programing i think you'll fry a pcm.

no, cause the pins are long, they stick in pretty far and are very snug.

i cant find the 2 resistor schematic but the MAX232 can be seen at http://www.akmcables.com/assembly.htm and i have the schematic if needed. i actually have the schematic for both on my site.

i would like to find the 2 resistor version. i have know about the akm site and how make than one, but there is a lot involved. i bought one from aldlcable.com (i think that is the site) and its pretty cheesy. it pretty much has just 2 wires from the obd 1 plug and cig lighter plug and then the serial port. i cant get tunercat to work and datamaster is intermitten when i reads. it has to re sync like every 3 seconds. i am wondering where the resiosors go and mabey that is me problem. i looked at your site and didnt see the plans for the cable. thanks again

andrew will fix his cable for you, he helped me threw making mine. i am sure if you get ahold of him he can work something out.

whats the 2 resistor thing??
lol @ the pin comment...all i have are wires i jam in the aldl connector about 20 flashes with no problems
why do you have 3 pins? i only plug in 2 to the ALDL..
and yes to test i would just read the pcm

i use the +12 from the connector vs the lighter

the two resistor thing will fit inside the DB housing. eliminating the need for the max232 board. i havnt used it yet but i am hopeful it works. going to test it tomm by reading PCM

i bought the kit and put that max one together and it didn't test out right using comunications thingy like it said, haven't gotten a chance to try it on a car yet, double checked all solders and reheated them to make sure there were no cold solders, still won't test out right...
