ok so i installed my AEM WB and my UTEC then i connected both to my laptop with a cheap usb-to- serial cable from a local computer store and everything was working perfectly fine. the next day i plug everything back in and my laptop wouldnt detect my aem connection so played around with the drivers but nothing seemed to work... So i went to radioshack and bought a $37 usb to serial cable and now MPS detects the AEM WB and it shows the AFR on the laptop for a moment and then it just freezes and wont show it anymore. I know its not the cable because i can see my afr when i use the AEM setting on Hyper Terminal and that works perfectly fine. I have tried to fix this for a week now and its really frustrating me. Anyone have any ideas on what might be wrong?

BTW: I'm using Vista and the RadioShack USB-to- Serial Cable

 

Are you sure MPS is compatible with Vista?

 

im guessing it is because everything worked fine for a day and i even tried installing xp but i got the same problem

 

those who are using the AEM WB what brand usb-to-serial converter are you guys using?

 

after tryin 3 or 4 serial->usb with the AEM, none of them worked and always froze/blue screen of death. running serial into the computer has been 100% working.

 

can you explain what you mean by "running serial into the computer has been 100% working." ? thanks

 

i use the serial cable off the AEM with no convertor and it has worked 100% of the time. I use the usb off the UTEC.

if you dont have a serial connection at all on your computer, cant offer any further advice because none of the usb convertors i tried worked more than 50% of the time.

 

After two freaking weeks of breaking my head installing/uninstalling every windows/driver possible i decided to go back and check all the wiring and i found my problem... This whole time the problem was a bad ground! At least that gave me some time to re read the utec manual several times and now i think i'm reading to do some tuning
