Ok, so I've searched high and low and I guess I'm not finding the right answers or I'm just not educated enough in the subject. I want to tune my 03 with an Osiris standard because I'm nowhere near any tune shops that support uprev, but what I've read is the 2003 has a narrow band O2 sensor and a wide band is needed to collect the data to send. So what are my options? I was told this gauge can be installed to work with the Osiris system. Does this replace the old narrow band sensor or is it just compatible with the narrow band? Any help or insight would be appreciated thanks. Links to gauge-http://uprev.com/secure/store/accessories/mtx-l-wideband-air-fuel-ratio-gauge

 

Are you original (2002) build or 2003.5 build? Early 03s had OBD issues that you had to rewire.

 

Looks like I have the 2003.5 I have the armrest. So what are my options then?

 

You may use Uprev with no issue then I believe. Message the user Seymore4 for more info... he did my tunes via email updates (I would send him daily driving data and data racing the engine (quick rpm change)).

It worked well for me so he may help you out.

 

Since you're posting in the coupe section I'm going to assume you have an 03 coupe.. and YES you have to rewire the OBD2 plug in the car before you can reflash. Not too hard at all, and there is a DIY posted on Uprev's site.

As you know 03's don't have wideband O2's however so you will need an aftermarket wideband to dial it in with etunes, you need to install this separately from the stock sensors, leave them all alone.

 

Alright thanks for the help. So then will that wideband work that I pasted above?

 

It should, I'm not exactly sure how to link it to the Uprev software and datalog tho. You might run that by them before you purchase anything
