Because the oem sensor only reads down to 11.1 and an aftermarket one reads down to 10.x. It does make a difference as you will notice on your logs that you will always bottom out the oem sensor on wot runs.

I think there is alittle confusion.. i dont mean to use it as a permanent fix, more as a temporary fix.
I do plan on buying a wideband soon, its just going to be used as a temporary so I can log it. Still wont work?

Also I'm not arguing the fact.. just looking for insight on it, since like I stated I cant afford an aftermarket wideband right now.

My advice is to stay stock for now. You have a HUGE investment in your car. Trying to be cheap can cost you dearly. Make a plan, save your money and then mod your car.

I just don't want to tune it without being able to atleast monitor my afr... I definitely agree though.

The oem sensor reads lower than that. The problem is it, similar to a narrowband, is not accurate outside typical closed loop AFR.

My stock o2 sensor goes as low as I tell it to, the 06 wrx has it mapped out for editing.

Thank you! If I move it to the downpipe and monitor it through RomRaider it will go below 11.1 right?

Don't. Buy an aftermarket one. Trying to save money you will do damage far in excess of just paying to do it right.

Awesome! My cable came in today! This weekend I should get some data logs and hopefully figure it out more through that. Does any one have some basic advice to do to it to get rid of that ghetto tune for emissions? Nothing for me to copy but to give me an idea where a lot of people went.

I understand your desire to tune yourself but I would suggest going with an etune for starters. I highly recommend Eric at TP and his tunes are a bargain. If you start by getting an etune then you will learn along the way e.g. flashing, logging, monitoring. Definitely get a wideband if you are going to go Stage 2 or beyond and then you will be set to tune safely. my 2 cents

So I did my first data logging last night. I'm alittle worried about some of the things I saw. I did 3rd gear pull and at my shift it showed a -1.5 in the fine learn knock and then again 2 time after the shift and I was moving in 4th.

Can you save your logs to google drive and post a link. Some knock around shifts or mashing the throttle is just noise.

If you have google drive save it there. Right click on it and select "share". You can then tell it to share the document with anyone with the link. Copy the link and post it here using the insert link tab on the message toolbar.

Here's a handy link on what parameters to log:

As someone who just jumped into this themself head first not too long ago, let me bestow my best advice for you.

-As mentioned, reading and understanding things is about 90% of the battle. The other 10% is applying it in real time. For me, it was a matter of just going out on long stretches, making a few small changes on the laptop and seeing the differences i the logs.

- You have 3 indredibly vital tools you NEED to monitor at all times when doing some tweaking.
#1.) A wideband 02 sensor. Might i suggest AEM UEGO, for its ease of use and fair price. Always make sure your AFR is within a safe range. (ex: 11.0 for a typical safe tune)
#2.) A boost guage, preferably digital with one decimal point. Many ppl bash prosport, but i found their new EVO digital boost guage absolutely bitchin!
#3.) Monitor your fine and feedback knock readings as if your life depended on it. This goes for DAM too. very key in the safety of you motor. A happy motor is a knock free one.


- As you start to understand something, practice it more an more. Remember, hands on is the best experience. BUT, only make small changes.


-If you have a friend involved, take turns driving, and one in the passenger seat with the laptop doing the fiddling. Take it slow and dont do anything rash. Have open discussions about what you are doing.

-Datalog as much as you can, and gain understandings of them. Best place to get practice is on this forum, with all the typical "this is my datalog, is everything ok?" type thread.

-Just keep in mind... with tuning, your telling the ECU what you would like it to do, not exactly what to do. With that being said, if the ECU does not like what it sees or feels, it will drop your DAM rating and cut back power to a safe range. This doesnt make the motor foolproof, but it does give you a good indication that your going the wrong direction.

-Be ready to get knocked on your ass a few times. Its part of the learning process. Many-a-times have i found myself scratching my head, having to go back to square 1 again because my changes werent taking effect or helping something i was working on. Be open minded and humble about it.

-Befriend someone who has more experience in tuning and pick their brain. Perhaps buy them a beer or two.

-The name of the game is patience.

I hope this works! This is my first time using Google Drive.
Just a reminder, this is a third gear pull and the -1.5 in the knock area is when I shifted into fourth gear and then again shortly after.
