thanks for the info

 

My laptop has four USB ports: 5, 6, 7 and 8.

When I have just the gauge hooked up to port 8, I can get it to communicate with hyperterminal but when I hook up the evoscan USB cable to port 5, then hyperterminal will no long read the guage. So I'm guessing there is some type of conflict but I don't know how to fix it.

 

why do you need that cable???

 

There are two cables. Which one are you refering too?

There is a Serail to USB cable from the gauge to laptop.

There is the Evoscan cable from the ECU/port to laptop.

I would assume that you need them both hooked up to the laptop to log with.

 

Are you setting evoscan up to log through your designated port. If you are set up to log on com 8 with hyperterminal, set evoscan up to log on the same port. Evoscan and your computer both have to be set to the same port.

 

Yes they are both set to port 8.

It's hit or miss if hyperterminal will connect to the WB if I have the Evoscan cable plugged in.

At times I get the same error as letitroll:



I'm now trying a way to get v2.1 instead of v2.2 to see if that will work for me also. Limitless' website only seems to let me download v2.2

 

thanks I will be doing this soon

 

Evoscan did send me V2.1 and everything works perfect for me now.

 

Question. Why cant you just use a USB cable, and cut & solder the blue and black wires just like the Serial cable? Just remove the serial cable altogether?

 

I actually looked into this, but the signal actually has to be converted. Its not the same type of communication. So the USB-Serial converter isn't just re-wiring everything.

 

ok, so i wired up the cable, bought the serial to usb cable and I am trying to get Evoscan V2.2 to log the wideband. I wont do it. I pulled up the driver in my device manager and it says that the cable is on COM5, so I select AEM UEGO on the wideband drop down menu, then selected COM5 under the same menu. After that, i checked the box for external wideband and started the log. It still wont read.

Can some one help me please?

Yes i varified that the blue wire was soldered to pin 2 and pin 5 was soldered to the same ground as the gauge. (used ohm meter to varify)

 

Make sure you restart you computer after you change comports in device manager (mangler).

 

restarted and no change. I removed evoscan, redownloaded the 2.2v and rechecked everything. Evoscan just wont retrieve any data from the UEGO cable. Anyone have other ideas?

 

Evoscan 2.1 and 2.2 dont have wideband support per Hamish. Download 2.0.

Go to where you downloaded 2.2 and change the end of the url to "v2.0.zip" without the quotations

 

I'm nearly positive you made the same mistake I did. Do you get a signal when you open up hyperterminal to that port? If not, read on.

AEM's instructions have a critical mistake. The written instructions, which are correct, are for hooking the wires up to a female serial plug. The diagram they provide is of a male plug. The pin numbers on a female plug are a mirror image of the male plug. So, if you used their diagram to wire up a female plug, then it won't work.
