I know there is a Cobb Stage 1 Base Map for a stock WRX running 93 octane. I live in Baltimore, MD where we have 93 octane at every pump. Just had to download the AP Manager, take the latest firmware, and download the maps specific to your car. It was originally for an 08 wrx but with the latest firmware, it works for an STI as well. I believe the only change as because there was more risk to breaking the adapter on version 2. I guess its too late now since I already payed the guy and its supposedly on its way but hopefully knowing its an AP-SUB-003 is all that matters. If anyone from Cobb can chime in on this it would be appreciated. I kept thinking that the model number, in my case the.-003 part, stood for the Version number. I think thats where some of the confusion lies with me and other as well. I believe they said the AP-SUB-003 will work on 2008 WRXs (and STis, etc.). When I checked with Cobb tech support last week before purchasing it, this is what they said I needed to worry about. However, the more Ive been reading, the more it seems its actually a change in the hardware.Ĭan anyone tell me if its possible to get an older version unknowingly Since I have a 2011 WRX, is getting an AP-SUB-003 all I need to worry about (meaning that its automatically got to be a V2).Īgain, I dont have it yet so all I know from the pic that the seller sent me is that its definitely not a V1.
