Hi all, just bought an aem widband to do some mild tuning and followed the instructions for connection to the evoscan software. I used the blue 5volt wire from the aem and soldered it to the correct pin on a old serial cable i found and ground the other pin. I used the same ground for both the AEM gauge. Problem is wha i see on the gauge is not what is logging at WOT. The gauge will say 10.5 while the log in evoscan shows 12.0. Also in what i found strange is that the logs will show a long string of 12.0 values like if the datalog is not moving fas enough or its losing signal somewhere. Is it a problem to use the same ground for the gauge and the serial ground? Help Please

 

anyone?

 

Which version of evoscan?

 

Hello,

I'm logging the aem uego analog output on the rear O2 pin, my eval in the Evoscan is : 0.03913*x+10 .

 

Shouldnt be a problem using the same ground. Make sure all your connections are good, and open hyper terminal and check if everything is on point...

maybe you have a bad uego sensor... who knows...

 

Its version 2.6. The wideband guage looks about right with the AFR so has to b the 5volt signal i guess. I check my connections again. Maybe ill try another r232

 

That's your problem, you need to update to version 2.7 beta 5.

 

Where can i do this ?

 

Or you can go back to 2.5...

 

+1 had to upgrade to 2.7 beta 5 to make mine work. PITA

 

Do i have to pay another $25 for the 2.7 beta5?

 

Anywayz I went ahead and paid the $25 bucks again and loaded the newest version. Everything seems to b working better now. Will keep you posted

 

All upgrades should be free. There is an upgrade section on the evoscan website.
