The first step you should take when you get your Accessport is to download the Accessport Manager software from COBB and check to make sure you have the latest firmware and OTS maps. This program is simple to use and you simply connect the Accessport to the computer using the included USB to micro USB cable. The micro USB port used to connect the Accessport to the computer is located on the left side of the device. We updated the Accessport firmware and double checked the OTS map revisions to make sure we had what we needed. We are going to be installing the Stage 1 V101 91 Oct map on the Golf R. COBB has a whole host of options for power augmentation with convenient stage power packages that include an OTS map and hard parts. This approach to performance is, in my opinion, one of the best in the business. My hat is off to the folks that put in all of the long hours getting these packages dialed in, because this is a very time consuming process and a great deal for the customer who doesn't have to do all of the tedious work involved in getting a set of components balanced and reliable.
Once again, we put the Golf R on the Superflo Dyno and performed the magic sequence to put the car in front wheel drive mode. The Golf R has a handy feature that allows the car to be placed in to a “Dyno” mode and drive only the front wheels. The rear differential clutch pack will stay disengaged as it does a lot of time when the vehicle is driving. The center driveshaft still rotates, but the rear wheels remain stationary. 
The bear always passes judgement on your dyno numbers. He has seen it all and he knows all the excuses. Put up or shut up. Before installing the Accessport on the Golf R, we wanted to get a baseline run for a comparable data set. We have previous baseline data on file, but with the change in wheel package, there will be a slight difference in power. The new wheel and tire package is slightly heavier and will result in a slightly lower wheel horsepower number than our original baseline data. Also, we installed the crankshaft pulley since our baseline power run data.
Here in this dyno chart, you will see two of our best baseline runs that we are going to use for comparison of the numbers after we install and flash the Accessport tune. Since our last dyno session, we have installed a new set of 18×9 Fifteen 52 Turbomac cast wheels and 265/35/18 Michelin Pilot Super Sport tires. This wheel and tire package worked out to be about 2lbs heavier per corner from the stock setup, so we expected to see a bit of power loss from our previous runs. The black plot here represents our baseline run before the Accessport tune. Peak horsepower comes in a 220.5 with peak torque coming in at 231.2. When we put the car on the dyno for a baseline run, we expected to see some lower numbers than the last time we ran it because of the increased wheel and tire package weight. We were down around 9 horsepower from the last best run after we installed the Fluidampr. I guess it might be time to look for some lightweight wheels. There just isn't a lot of options for cars that have the 5×112 bolt pattern that look good.
