I understand that the S300 can log wideband afr's using the eld input. A little confused to if the S200 can, from my readings. I interpret the information on the forum as, the S200 can as long as you run in open loop and use the wideband output from plx into d22 on ecu. Am I correct or way off course? Thanks in advance.

The s200 can only read the wideband signal in open loop through the standar O2 input.

it might help if all the documents showed the s200 way and s300 way,
as most of the documentation is for s300.

Including setting up wideband :).

so are you saying that the s200 cann read if you take an old o2 and cut and use the plug as a way in the honda ecu

If you upgrade to RE4 you can use the ELD as an input. for the wideband signal and use the O2 input for the narrowband signal to run in closed loop.

if i wanted to use a aem uego, would i have to enter all the scalers or just 0- and 5 volts?

If it is linear, then you need only 2 data points.
