I just ordered a glowshift wideband kit (gauge,control unit and bosch 4.9 sensor) . How do I hook it up to my chipped p28 ecu so I can get readings to go to my ecu control datalog program?

 

If you're using crome you're limited to using the O2 input. Otherwise you have ELD, B6, and EGR Lift as options as well. Output of the wideband goes to the input you choose.

 

I dont know what eld and b6 are.
I am using the free crome to tune. I will be using ecu control and/or freelog to do datalogging. So I hook the wideband 5v wire to the stock o2 signal wire? Does the datalogging software convert the voltage signal?

 

Do I use the stock o2 or does the wideband replace it?

 

pgmfi.org, read read and read some more. its in there

 

Ya I am sure it is in there somewhere, thanks for the tip smart ***. Insted of searching for hours, how about i just ask a question on the good ol h-t? sounds like a normal thing to do.

 

basically. make the ecu run in Open Loop all the time (stock narrowband 02 disabled) by changing the tune.
hook up some sort of 0-5V output (dont know for your specific apparatus) of the wideband into the stock 02 signal (D14 in ecu plug, white wire)
perform this modification to the ECU if you want 0-5V resolution instead of 3.8V that the ecu can normally handle. this modification also stabilizes the signal as it goes through the ecu

Then adjust your settings in free log to read for a wideband O2 sensor and your set.
add a 4 pin header to the ecu, or have you already. Then you need a cable to convert serial to USB, pretty much any type can be used
here are some more informations

now be a good boy and eat your num num but next time, before calling somebody a smart ***....try to do a little searching rather than wasting internet bandwidth with questions that have been thoroughly covered over and over again...thanks
