  1. Hey there! Changes on the AP are made to "Real Time" data and will persist across key cycles. Those changes will reset to the map default at an ECU reset or map change. Marshall@COBB
  2. Where are you located? Our Accessports currently only support the 2005-2012 USDM Legacy GT. Marshall@COBB
  3. I would uninstall the intake until I could get a tune for it. The SPT intake, like most intakes, makes power by altering the airflow over the MAF sensor. This then fools the ECU into leaning out the mixture based on this altered airflow. So you are making power by running leaner and this is not good. This is probably why you are seeing better MPG as well. It isn't as if the intake isn't "working" it is doing what it was designed to do. However, this is not what most tuners would consider a proper tuning strategy. As you increase boost pressure and performance, like with a stage2 tune, this lean condition will only get more pronounced. There are several tuners that offer E-Tuning services that you can get a calibration for your intake from. Clark Turner is one. You can also check out our complete list of tuners and dealers at www.cobbtuning.com/dealers for the tuning facility nearest you. Also, check out www.xpttuning.com they also offer E-tunes!

  4. At this time we do not have OTS map support for the SPT for any of the Subaru models we support. This is partly due to the fact in years past, the SPT hasn't been the greatest intake in the world from a tuning standpoint. You will want to source a custom tune for that intake. You can always revert back to the stock intake as well. The SPT isn't really going to give you any more power.
  5. For Legacies, the AP-SUB-002 is only compatible with the 05-06 LGT. AP-SUB-003 is required for 07 and up LGTs. Bill
  6. Log the standard parameters, there is a default list. You might add turbo dynamics to that so we can see what the ECU is trying to do. How are you viewing boost pressure right now? Travis COBB Tuning
  7. Shello, The AccessPORT is able to datalog without a laptop. Check out this video on a tutorial on datalogging. You can view the logs on a computer with excel or similar spreadsheet software. http://accessecu.com/cobbtuningweb/productpages/bmw/135i/accessport/video/datalog.html Travis COBB Tuning
  8. Hi Shello, I apologize for the issues you are having but I think we can get them sorted out rather quickly! You can run a stock map on your AccessPORT without uninstalling. Just flash the stage0 or "stock mode" mapping onto your car and you are now running a "stock" calibration without uninstalling and you can datalog like you would with an OTS stage map. That will let you easily compare stock car behavior compared to the COBB Tuning map. You can find these calibrations here: http://accessecu.com/accessport/subaru/lgt/LGT-Maps-05-Stock-Intake.html That said, What exact map are you running? Were you logging when this occurred? How did you determine that boost had run so high? At 19psi you are about 4lbs over the peak target boost for a 93 octane stage1 map. If you can do a log and post that, it would greatly help us see what is going on with the car. If you did hit 19psi, I am surprised that the car did not hit boost cut. I am wondering if there isn't something else going on. Do you have an aftermarket boost gauge or other device? Let's see what the ECU is seeing and go from there. Also, it is not unheard of for the car to "learn" a bit so that might be why you are seeing lower boost numbers now. Boost is also highly dependent on RPM and load. So if you are going uphill in 5th gear and punch it from 3,000 rpm, that will put more load on the engine than if you are flat and level going from a roll in 4th or 3rd. You can PM us here or send me an email directly to travis.geny@cobbtuning.com if you have further questions or concerns. Travis COBB Tuning
  9. Nope! The 2b is just a newer hardware design to eliminate the dongle, but both work equally well. - Ian
  10. For the Legacy GT, the SI-Drive system is unalterd by the AccessPORT, so the throttle mapping for I, S and S# are unchanged and will perform just like stock. However, the requested throttle tables are Base Map tables so if you wanted to flash on different calibrations for different throttle mapping, those would have to be reflashed as a basemap and can't be done through a realtime flash. Let me know if that answers your questions! If not I will get one of our tuners to respond. Travis COBB Tuning
  11. Hi there. 1. Yes, the OBD port is the same for logging and flashing. You should not be in test mode for logging. Test mode is only for reflashing a map. 2. The e-tuner would send you a map and then you would decide if you wanted to flash it as "reflash" or "realtime". You should always reflash the map that has all the changes necessary for your tune/mods. Flashing via real-time only changes a small subset of the most frequently tuned tables (boost, timing, fuel). That is, it overrides the reflash for those 10 or so tables. So, it is generally used when you want to temporarily run a different map for a specific reason, such as the fuel economy map, anti-theft map, etc. The real-time map changes will remain until you reflash another map or disconnect the battery. You do not have to be in test mode to flash via real-time. Bill
  12. COBB Tuning is opening a new location in Fountain Valley later this fall. This will be a full retail, fabrication and tuning facility. Stay tuned for more details on an opening date. Travis COBB Tuning
