I have an 03 Coupe 6MT that I recently bought an Osiris Standard for. I got it in the mail today and realized that I'll need a wideband o2 sensor to log A/F data for the eTunes. I just ordered the wideband sensor from them and they mentioned that I only needed one.

My question is, where do I weld in the new o2 sensor if I only have one of them? Does it matter?

Also, is anything else needed when doing remote tuning with Osiris and flashing my ECU? I believe that I'll have to re-pin my ECU, I'm checking that when I get home from work.

Thanks for any help.

 

You need to repin the OBD2 plug, not the ECU. Here's the link to the DIY: https://uprev.com/documentation/2003...%20re-wire.pdf

 

Any tips on how to pull this pin? I feel like I'm going to break the damn thing in the process of getting it out.

 

Follow the instructions on the DIY its pretty self explanatory.
