A couple of European forum members have been in contact with them and were planning visits.Īlso see our discussion threads on the Cobb tune results and on VTG and compressor wheel size generally. Comments/Replies) and search for threads on discussing Ehresmann. Stage 1 (filter and ECU only) tune gets around 400hp.

You can simply flash these tunes with your AccessPort, without having a custom tune made for your car.Ehresmann Automotive GmbH gets 450 crank hp on a 718S 2.5 with their Stage 2 (downpipe) tune. Many intakes for the Subaru WRX will have off-the-shelf tunes available, such as the Cobb Big SF intake and Mishimoto Performance Intake. You'll hear the turbo spool up and hear blow-off sounds. Stage 1+ might add a bit more power over Stage 1, but the biggest change you'll notice is more sound from the intake. When the intake is modified, this will change the readings from the MAF, so some adjustments need to be made. With a different intake, the value it reads will change, so this needs to be corrected by flashing the ECU. The car senses how much air is coming in with a MAF (mass airflow sensor) so it can determine how much fuel to inject. Some additional tuning is required to keep the car running correctly when installing any intake. With the 2015+ Subaru WRX, the stock intake isn't very restrictive, and while an aftermarket one main give some small gains, it's small compared to the jump from stock to stage 1, or from stage 1 to stage 2. The difference is that an intake is added. In terms of powered added, Stage 1+ isn't a big jump from Stage 1. Just make sure that it's unmarried, or fully uninstalled from the previous car, you can't use it. The AccessPort costs around $650 new, but you can get one used for much cheaper. If you want to start modding your car, buying a Cobb AccessPort is a great place to start, and you'll need it to tune your car for any further physical modifications such as the intake and downpipe. Stage 1 tunes will also fix this, making the car overall much smoother and easier to drive. On 2015+ WRXs, many people complain of 'rev hang', where the RPMs will take too long to drop shifting between gears. Instead, the car just keeps pulling all the way to redline.Īnother big change with a stage 1 tune is that it fixes rev hand. It also smooths out the powerband, eliminating the mid RPM dip around 4.5k present in the stock tune. It also smooths out the throttle, making it much more linear, fixing the oversensitivity of the stock tune. Stage 1 adds significant horsepower over stock, around 30 whp. The AccessPort also allows you to monitor some important parameters from the ECU, like knock correction, fuel trims, air-fuel ratio, intake air temperature, oil temperature, and more. It simply plugs into the OBD-II port under your dash, and with the press of a few buttons, your car will be Stage 1 in a few minutes. The AccessPort comes preloaded with tunes for the various stages. If you have a newer model, your only option to do this is using a Cobb AccessPort.
