I've searched this thread up and down and haven't really found what I'm looking for. I found one post on how someone had made their own serial cable to get the AEM UEGO to log in Evoscan, but I was wondering if this is the only way to do it or not? So far this is all I've found:

I basically want the most simple way to "connect" the UEGO so I can log AFs in EvoScan.. Any input or advice??

 

the instructions to do so are right up top, if you do a search, i know theres a thread around here for that logging capability. if you procceed to have trouble, check the openecu.org thats your best bet.

 

Yea, you have to make your own cable and connect it to the 2 wires. I think it's easiest to start with a serial cable and cut one end off than to make a cable from scratch. Also I had to get a USB > Serial converter. The one at bestbuy worked but cost double what you can get one on the internet for.

NOTE the instructions are for the male end (the laptop has the male end) so they will be almost opposite of the female that you will be working with. Like if it's pins 2 and 5 on on the male end in the instructions it will be pins 4 and 1 on the female connector. Now get a multi-meter and check continuity to find the wires for the 2 pins you need. (I tried the colors that AEM listed and did this 5 times before I went back in the house and got my meter and got it right). You can check continuity on the ohm setting on your multimeter in case you didnt know how. When you have continuity (connection to the correct pin and wire) the meter should read 0 resistance (or close to it), when you have a the wrong wire it will read 1 meaning it has infinite resistance.

 

the easiest way to do this is definitely to pick up an unassembled assembly with pins from radio shack.. It takes a few minutes to crimp 2 pins and stick them into the assembly, plus they are labeled on the back what pin# is what, which makes for less confusion. Cutting up a cable is just a little harder to figure out, plus it'll cost twice as much.

 

You make a very valid point MJ. I guess that would be easier.

I already had an old serial cable laying around so I just used it and saved a trip to RS.

 

Thanks for all the info guys. I'm going to give it a whirl and hopefully can figure it out.

One more question I don't fully understand, when I'm not logging what happens with the two wires coming off of the gauge?

 

"If a tree falls in the woods and nobody is there.. Did it make a sound??"

Basically if its disconnected, you won't see anything, but the data and output are still there.. But its okay to leave it disconnected as long as its wires aren't exposed to get shorted.


In all seriousness, if you wire up the RS232 port, DB9 connector, basically you can tuck it away somewhere when its not in use. You don't have to disconnect it, I soldered mine to the wires and can tuck the wires away with the connector on it whenever its not in use. The AEM isn't mounted in my Evo, I use a TurboXS Tuner in the Evo, its actually going to be mounted in a Crown Victoria (X police car) Supercharged project I'm working on.

 

That's the answer I was hoping for, thanks. Now I just have to decide where to mount it. Good luck with the project car!

 

what do you guys do to remedy the "openness" of the serial cable? i'm a nitpicker and i love clean installs and all that.

 

I bought a 9 pin din connector and shell kit, set the pins, and shrinkwrapped the end and if the wires are short, the entire length of wires, then put the plastic shell on it to protect the back of the DB9 connector.

This unit is intended for something other than my Evo..

 

i just bought a db9 to usb cable but my computer says it cant find the drivers for it work? any help?

 

the adapter is supposed to have its own drivers that setup a com-port assigned to the cable. if the drivers aren't built into XP you have to get them from the manufacturer website.

 

yeah just as jack says buy the serial port and just connect the wires that go on the widebaand to the port and then you just hook it up to the laptop, i had a hard time at first but its fairly simple once you get it.

 

anyone tried splicing directly into the proper pins on a usb converter?

is the belkins usb converter good? which converters do people use? what's good or bad about converters? noise? i hear a lot don't work when you buy them.

Got this one from best buy, works great.
