I am a newbie and I am a bit confused about EVOSCAN


I have a AEM ueqo wideband and tried hooking the white 5v data wire to the rear O2 on the ECU and it threw a code. By reviewing the program it would seem that you are expected to hook the wideband into a separate serial and then serial to usb rather then getting the data through the ECU pins. Help me!


Also the fuel reading from the 02 on EVOSCAN is in volts. any way to change this to understandable numbers? Help me Help me!

 

you need to install the o2 sim patch or use tephra v5 rom to get rid of the SES light.

what is the min afr value that the AEM can read?
what is the max afr value that the AEM can read?
are you really familiar with ecuflash?
what rom ID do you have?

Sorry for all the question just need to know what direction to help you.

your evoscan formula will be different since your afr range is different, 10=min 20=max so your evoscan forumla would be 0.039218*x+10
