Can't get wideband to log
 

Yesterday I spent the entire day trying to get my wideband to log again. For a whole year I had no problem logging and tuning my car until last week when I wanted to log my car I had this problem. What has been happening is when I log my car on the first try it would work fine but on the second log then on all I get is a 0 as my afr and in the lower corner it says aem error: port close. I try a new ground, rebuilding my female serial port, new cable, hyper terminal and had no luck at all. I have the gigawire from radioshack and am running windows 7 home premium edition. It has been working fine for a year so I don't understand y it won't work anymore. Can someone help me or the people who has fixed this problem tell me what u did so I can try it out and see if I can make it log again.

do you have access to another computer and/or cable to see if you can isolate the problem to one or the other?

Have you tried uninstalling Evoscan completely and reinstalling the program?

Have you looked to see if the com port setting for the wideband has changed itself at all?

I am goin to try a new laptop and see if the ports on the old laptop r bad but I doubt it cause I use those ports for tactrix cable and it is fine.... And I tried a new serial to adapter cable and still no success

Yea I uninstAlled evoscan 2.7 and install version 2.8 and still don't work

I know before i had to go back to 2.5 to make it work. Its really inconsistent at times... some will work and some wont.

Yea it changes almost everytime I go out and log and always switch it to the right port

I don't have version 2.5 and it ran fine for a year don't know it suddenly won't work

Well it might just be your gigaware cable... maybe uninstall the driver and try it again. Also getting another cable and see if it works, but that means you would have to spend some money when that might not be the problem.

It was a nightmare getting my AEM wideband to work with evoscan. Long story short I am using Evoscan v0.99 lol

I bought a new gigaware cable but still the same problem...I did uninstall the cable driver and now when I install it and plug in the cable it won't install properly....I tried to install the new and old cable but still have the same results...tonight I wil try to install the driver again

It worked like a charm for a year and now out of no where it is making me lose my hair haha

Make sure every driver for the cable is removed. That happen to me as well.

Also try different COM ports.

Also try different COM ports and make sure they are selected in evoscan.
