AccessPORT ProTuner EFI Logics makes big power with the 2010 Subaru Legacy GT

While the AccessPORT for the 2010 Legacy GT is not yet available, a select group of ProTuners are making good progress with the BETA version of ProTuner software for this vehicle. The 2010 Legacy marks a complete departure from the turbo system we have known grown to love and trust on turbocharged Subarus of the past. Instead of locating the turbo above and behind the engine, the new Legacy has its turbo slung under the engine. In addition, this vehicle sports an all-new ECU. BETA testing is well underway and ProTuner EFI Logics was able to test the new software on a willing customer’s car with some very impressive results.

While peak hp increased 9hp to 223hp, MASSIVE gains of up to 60hp in the midrange really brought the car to life. This was due to huge torque gains of up to 90ft-lbs, bringing peak torque to 304ft-lbs from the stock 214ft-lbs. Looking at the graph, it’s plain to see that these gains extend throughout the entire rev range! Note that this is on a bone stock 2010 Legacy GT. No intake, exhaust, fuel grade change or anything was added to the stock car. These impressive gains are simply from remapping the ECU with a proper AccessPORT calibration.

This indicates a smaller turbo than what is currently available on the STI and WRX. With exhaust and intake modifications, power output could be increased by another 25-35hp with even more torque. With the Legacy growing from smallish sport sedan to a much larger tourer, the added power will be welcome. In addition to the AccessPORT, look for other parts coming online for this vehicle in the near future as well.

  1. That increase in torque is always welcome in a heavy car like that.

    But I think that at least 300whp/wtq will be good for this car, hovering around those power figures between 2000-5000rpm, hp peaking somewhere at 5000rpm tapering to 270 at redline, and the tq peaking at 2750rpm tapering to 250 around 4500rpm and continuing until redline. I feel this is ideal, however, I am not sure if realistic. Perhaps a twin-scroll can get these numbers?

  2. Since this was over a month ago, roughly how long until we can expect to see the ‘beta’ label lifted and off the shelf tunes available?

    Are we 30, 60 or 90+ days away from actually being able to purchase a pre-loaded AP?

    • Beta Off-The-Shelf maps for the 2010 Legacy should be available by the middle of next week and AccessPORTs should begin shipping with these maps preloaded by the end of next week. We will also announce a firmware update that can be downloaded with all beta OTS maps included.

    • Jeff, looks like the 2010 LGT maps are going through final firmware validation and should be ready early next week. We had a few more engineers make the move down to Austin, TX this week.

  3. The article above says the LGT only has 214lbs of tq and 223hp. It’s advertised as coming w 265hp and 258lbs tq. What’s up w that?

  4. After a ride on the highway with some fairly spirited driving there was an odor coming from the engine. Kind of smelled like hot plastic. Is that the clutch heating up from the tourque? It was also a wet night. Could it have been from rain cooking of the exhaust?
