  • COBB Rolling Boost: Load up the turbos to create boost for roll race events. Simply hold the cruise control button, “Set Coast” to build boost. Note: Feature must be enabled in ECU calibration for use.
    COBB Speed Density Tuning: Tune using the MAP sensor instead of the MAF sensor for big-power builds that exceed the stock MAF sensor's maximum capacity.
  • COBB Fast ECU Flashing: Allows ECU map change flashing time to be reduced to 40 seconds or less! Learn More.
  • TCM Flashing: Reflash the Transmission Control Module to enhance launch control, perform factory gear learning, and adjust clutch capacity and touch points. Note: Feature is only available on AP3-NIS-006 and AP3-NIS-008
  • TCM Adjustments: Run clutch gear learning, or adjust clutch touch points, and clutch torque capacities. Note: Feature is only available on AP3-NIS-006 and AP3-NIS-008.
  • TCM Logging: Log transmission data monitors to diagnose mechanical issues or improve transmission characteristics. Transmission monitors can be logged simultaneously along with Engine monitors. Note: Feature is only available on AP3-NIS-006 and AP3-NIS-008
  • TPMS Learning: Easily re-program TPMS sensors for new wheels and tires using the Accessport and prevent cumbersome trips to the dealership!* (*requires common Tire Pressure Positioning Sensor Tool).
  • Bank Air Learn: Relearn and rebalance airflow between the left and right intake manifolds.

Map stock Stage 1 review

I spent a fair amount of time looking at the Cobb maps and reading feedback on other sites that eventually lead me to rav review for maperformance OTS tunes.

There are people that like the stock tune over Cobb and there's a lot of talk about the Cobb tune making the car more drivable. After trying the Cobb tune and Maperformance, I fully understand these reviews

The Cobb tune's linear approach sacrifices low end torque and fast boost spikes for a stronger upper end power band. You probably gain MPG's with the sluggish lower end power you spend in your day to day driving.

The stock tune is great for lower end immediate response for passing cars. It's forgiving for those that don't want to downshift all the time to feel that boost at a wider or a more daily driver type of RPM range. The problem is the burst is short lived. The car dies out and high RPM's, and the fun is over, forcing early gear shifts.

Going from Stock to Cobb is a total trade off. The low end boost is gone. The torque curve has moved to the right in the RPM band. It doesn't matter if you plant your foot, the low end torque takes a bit of a hit. The hit is notable and a let down. What you gain in the higher RPM range is not where your daily driving is at. I could understand feedback of wanting to go back to stock. You also gain boost consistency with Cobb, with the stock tune feeling like a bit of a mystery to get it to boost up every time you want it to. There are feedback threads out there where people feel like they can't get the stock tune to feel the same boosting up, which leaves performance peeps annoyed with the inconsistent power.

Cobb's Dyno chart show's no drop in the low end on their site, Map's dyno chart shows it clear as day. I now trust Map's dyno graphs after feeling the results myself.

This is where Map's tune comes in. I've never read complaints about wanting to go back to stock on the Map tune. While I can notice the torque curve has moved and the stock tune still gets a very small edge for that low end torque (Even Map's dyno charts show this is true just a little, credit to Map for honesty), almost all of the low end power is back along with a stronger top end power band that beats out Cobb's tune.

This provides a more complete RPM band for making power and holding that power on the MAP tune.

After feeling like I traded off too much with the Cobb tune, the Map tune brought my smile back. I no longer feel like there's a trade off, all upside except for my MPG. I probably drive more aggressively now.

The stage 2 torque curve for Map's stage 2 kit looks great. Nice stable torque that holds though the RPM band, leading to a stable rise in HP as RPM's go up. This is what a dyno should look like. If Map's honesty holds, i'll look forward to feeling it when I go with their stage2+

I'm a second time WRX owner going through the upgrade process a 2nd time. I sold my stage 3, 10 years ago.

Advice to others.

Stage 3 is horrible, do not get a FMIC, the turbo lag isn't worth it. Smaller 2.0 engine + bigger turbo + FMIC =turbo lag so bad it doesn't matter what your peak power is anymore. No need to upgrade to stage 3 or swap out turbo's if you want a drivable car. Stay at stage 2+ and enjoy a wide power band for making power, the ability to make a track car and still use it as a daily driver. Stage 2 clutches are horrible too. These clutches are meant for launching, not for the McDonalds drive through where they get torn up trying to slip the clutch at 4K RPM.

I love that I don't see stage3 rotated mount FMIC kits out there for the new WRX's unless I'm blind. Perhaps the community learned it's lesson. I'm 10 years out of touch with the times.

Looking forward to doing the build right this time.

Cheers

A whole new car!

Installed the Cobb Accessport on my stock 2018 STI. Setup took ~30 mins and learning the features was rather easy. Noticeably more pull through the lower RPMs. Launch control and flat foot shifting add a new level of fun when playing around.

As expected

The tuner and the A pillar mount work as expected and I'd highly recommend subaru owner looking to get a little more out of their cars to get an accessport.

Best mod for your WRX or STi

The Cobb AP is the best mod I have done to my 2020 WRX. It allowed me to monitor critical data straight from the ECU. It also gave me the ability to get my car tuned. Setup was quick and easy. Once installed, I flashed the MAPerformance Stage 1 OTS tune to my car, and WHOAAAA!!! The quirks from the crappy stock tune were gone! It made my car fun to drive again!!! Do yourself a favor and buy it from MAPerformance!!

Amazing

Bought the access port for my 2011 FXT. What a difference the stage 1 made. Power is always there and ready to go. Took away all the sluggish feeling. Bought the SF intake to go with it but haven’t installed it yet. I also like the ability to look at what my engine is doing while I’m driving. A must have device.
