    COBB AP and CAI

    So, I just got my AP v2 in today for my 07 sti. I've been running a TBE and Injen CAI without a tune until today. Of course, it's been running lean, and I was hoping the AP would fix that. I have found though, that there is no map on the cobb wed site for CAI. Is there a website somewhere to download maps others have made for free? I want to get the most out of my CAI. Right now I'm running Stage 2 of the pre installed maps but it doesn't support a CAI.

    Can anyone at least point me in the direction of how to tune my CAI to my car? Is there a web site of people using the Accesstuner Race program?

    Do you have a WBO2 sensor? If not, you're only able to tune the closed-loop section of the MAF scaling.

    You would need to get a customized tune (either opensource e-tune, or a live pro-tune). It would probably be easier to take the injen CAI off your car and get the stock one back on there, or get an intake that is compatible with the COBB maps. The injen is not a very good CAI anyway. It is more important that you have your car properly tuned. As Matty indicated, it wouldn't be a bad idea to get a wbo2 sensor installed in your car with an A/F gauge so that you can see the A/F ratio accurately. This would be very useful in tuning the car if you decide to go e-tune or pro-tune.

    There are many options. Torqued Performance is a fairly common e-tuner (some don't like them). We have people on here that can do e-tuning. Depending on who you use they may not like the injen intake anyway. I would say since you have the AP the best option would be the sell the injen and get an AEM or COBB intake (or go back to stock intake), and run their ots map.

    READ EJ257s POST! You are missing a critical hardware component necessary to scale your MAF for the CAI.

    You have two options:
    1. Purchase and install a WBO2 sensor and opt for an Etune (or tune yourself)
    2. Schedule a dyno tune, where the tuner will likely use an Exhaust Gas Analyzer (EGA) that is inserted into your tailpipe (giggity)
