Cobb APV3 Subaru Gauge Suggestions

Goto Gauge's select which you would like to change and scroll to the suggested item until at bottom of list. 

Gauges to monitor on the AP:


AF Learning #1: You dont want this number out side of + or - 10% If it ever does you probably have a leak.



Fine Knock Learned If you see this number over -3 you probably have gotten bad fuel or have a boost leak (Don't reset ecu. Drive carefully for that tank and when the gas light comes on fill with fresh 93 from another station. If the ecu detects no more knock it will add the timing back in)



DAM  You want this number to be at 1. Changing of this number could mean you have bad fuel, poor condition spark plugs,boost leak,vac leak, fuel issue.  (Don't reset ecu. Drive carefully for that tank and when the gas light comes on fill with fresh 93 from another station. If the ecu detects no more knock it will raise dam back to 1 when it no longer has the issue)



Intake Temp  This is temp measure at the INTAKE pipe (MAF sensor) Avoid doing pulls if you see the intake temp above 100* If you are in traffic it's good practice to let the engine cool down before doing any pulls. Also if your not running a heat shield or box this number may be very high in traffic or stopped. Wait for this number to come down before doing any performance pulls.



Boost You can log target boost on the tune a few times to see what your target is, you want to ensure the car is always hitting close to target. Over boosting can lead to engine damage, and under boosting could be signs of a boost leak which again can cause damage.


For the 6th gauge if you have a STI or WRX with a EJ25 Use injector duty cycle. If you have a 2015+ WRX use intake temp manifold.


Injector Duty Cycle (STI running stock injectors) If you have a EJ25 On stock injectors Its important to monitor the injector duty cycle to ensure your not maxing the stock injectors out. When they go-to 100% They are now wide open and cause uneven fuel flow, loss of performance.  If you are running our tune and see this going over 95% please goto our www.getmtuned.com/alreadytuned page and get us logs over so we can correct the issue.


Intake Temp Manifold(FA20 2015+WRX)  This is the temperature measured at the manifold after the inter-cooler. This is the temperature of the air entering the engine. Avoid doing pulls if you see the intake temp above 100* If you are in traffic it's good practice to let the engine cool down before doing any pulls. Also if your not running a heat shield or box this number may be very high in traffic or stopped. Wait for this number to come down before doing any performance pulls.
