Bring this back to the top with a cable how to
The parts are cheap!
You need two resisitors
with this stripping, I believe they where the 1k type
transistor
then you need about 8feet of cable, the 9pin serial connector and ends
this is the basic layout for the parts
I used the pieces of a broken cable to show the layout. The transistor is suppost to have three pins the center one connects to a resistor and goes up to the white wire. On the ground side you can see where it hooks in, then the resistor going to the left actually turns and come back to the middle when you plug it into the serial end.
pic of someone elses cable inside (I taped mine up already)
Under the dash I unbolted the ALDL port so I could check the wire setup. The black wire is ground so you connect the black wire from your WinALDL cable to that port and then there is an orange wire in the ALDL that should be in E (or the 5th one over, second from the end) that the data line goes into.
See my results below and help me interpret them!
My baseline run started with me sitting at a stop sign, I reached over and clicked the start log... (see RPM graphic below) as I sat for a second I pulled out onto the road in drive (not OverDrive since I just put the 35's on haven't regeared yet). I put the peddle about half way down and let it shift through first and second, once in third I left it roll for about 15seconds then I gave it a punch and wound it up and left off, just before I turned off the road I reached over and clicked stop log on the WinALDL program.
Here is a graph from excel of the data recieved from a 90 second drive
actual log here in HTML format
sensor data from the run
update: Cable is working and I have an idle test, a baseline cruise with a skinny peddle jab towards the end (speaking of, the 35" MTR's run great up to about 64MPH so far (or 72MPH actuall -using speed calculator from 4low.com going from 31 to 35's) , thats what my graph shows for the RAW:speed during the jab. if you go by the speed sensor I hit 103MPH at 3825RPM /forums/images/graemlins/confused.gif). OH I ran in Drive instead of OVER DRIVE since I'm running the 3.08;s for now. I'm going to toss some 31's on and run a couple base lines, then after the 4.56 swap I'm going to run a couple baselines with the 35's.
So give me a run down on the:
IAC CT MAP TPS INT O2 data... whats what and what do I need to look for? the RAW
2 is all over the boards, RAW:CT decreases during the whole run, the rest to look to rise and fall with the RPM's or stay constant.
I'll get some graphs and info up here as soon as I pull the data off the laptop to here.
I got a rich flag popped up when I was speeding up, I'm guessing thats normal.
The knock counter hit 73 at idle, at around 55-65MPH it pegged out at 99 the whole time.
voltage was nailed at 14.3 and 14.4 with the stereo/amp and clearence lights running, 14.5 at idle.
*********************************************************************
Made a cable and plugged it in to the laptop, got the COM1 = OK but no info?
tried on second vehicle... nothing
tried plugging it in and turning the truck on,
tried starting the truck and then booting up the computer
checked to make sure they where plugged in right and the black wire was on the ground and the white connector (ont he winaldi cable) was on the orange data (E) spot. /forums/images/graemlins/thinking.gif
Checked to see if the modem was on COM1 and its not, serial cable is good and we just got the connections fixed up and insulated each layer with electrical tape /forums/images/graemlins/confused.gif /forums/images/graemlins/dunno.gif
I'm going to pull the cable apart and double check the connections.
anyone done this?

, $60 for the bare pin...
. I guess it will have to be serial.
