Cobb Green speed EPA regulations update tuning modified Subaru's.

On april 18th Cobb changed everything. Long story short Cobb Tuning removed a lot from their software functionality per EPA regulations and the software is now much different and more limited only supporting the areas allowed by the EPA. While the new software update limits some things we are still tuning Cobb AP daily and making great power! Cobb is also currently developing new CANbus based flex fuel kits among other power adding parts that will all fit within the EPA’s new regulations. We will be offering special pricing for all returning customers making updated modifications to best utilize the new Cobb AP abilities and Cobb’s green speed program. We fully support the Cobb Green Speed program and are excited to be tuning efficient, powerful and CLEAN Subaru’s using the Cobb AP and our Etune services.

Those planning to continue to use the Cobb AP will need to re install all OEM emissions equipment including TGV’s, secondary air pump and EGR. Please note while most people remove these parts there is actually NO need to do so. Non of these emission related items hurt or effect engine performance they are simply there to help keep the emissions low under normal use like idle and cruising conditions.

    Hello I’m looking to take my 04 sti back to stock or go all out haltech system sense my access port isn’t much use for now. It currently has a full straight pipe. Blousch 3.0 dom. Perrin frontmount. Perrin 3inch intake with a AEM filter. Aftermarket BOV. Id1000 Injectors. IAG tgv deletes. Dw 400 pump. Iag fuel rails. Fuel pressure gauge. Cobb’s e-85 sensor. And the motor has forged rods and pistons. I understand the need to replace the Down pipe to one that is EPA compliant. Then also the Tgv”s reinstalled and hooked back up. But what about everything else? Can the rest stay on the car just not be utilized or do I need to get rid of mostly everything?

      To use the Cobb without any CEL you would need to have OEM tgv’s, air pump, EGR and Gesi catted downpipe. Cobb will not longer support the flex fuel sensor kit/custom TGV inputs. Our Haltech package would allow you to keep the mods as they are now. STI haltech
