how can i hook-up my aem wideband to my cromePRO tune ecu so i can datalog??? thanks!!

 

wire it to #1 o2sensor d14 or d16 im not sure
then go to file/seting/tuner logging/sect then match the reading on your guauge and crome with the offset downright the window

 

oh its that simple!!! ok ill try that thanks man!!

 

i know this is an old thread but is this really this simple cuz ive read that you have to take some resistor out and put a compasitor in. now i can do this if thats what i have to do but i need to know for sure what i got to do??

 

You will only need to replace a couple resistors when you want to use the ELD input, EGR lift input or ECU pin B16 when using eCtune. Crome does not have any setting to switch between WBO2 inputs. You have to configure your wideband to use voltage scalars that work between 0-3.** volts. If you go into Crome settings/tuner logging and select your wideband O2 in the drop down. It gives you the voltage scalars that you should use.

 

so just disable the o2, wire the white wire to d14 and go in the settings and select aem wideband and it should work???

 

Don't disable the O2, unless you want to keep the ECU in open loop and not use the signals given from the WBO2.

Just remember that when you use the wideband in D14 through the ECU you are only going to be able to read between 0v - 3.38v. Therefore when using the AEM UEGO sensor. You are only going to see between 11 - 16.8 AFRs. That should be a sufficient AFR range for tuning. Unless you want to run leaner than 16.8 and richer than 11.

 

ok so don't disable it but pin it into d14 so that the stock one isn't hooked up and it should be fine?? and i don't really see a reason to go any richer or leaner then that and if so i should b able to just look at the gauge right?? and when i do this does it effect the readings on the gauge at all cuz i like to monitor the air fuels even when im not tuning?

 

Yes


Yes.

No. The gauge reads it's info directly from the sensor/controller.

 

ok thanks a lot... ill try this when i get out of work and let you know how it turns out
