COBB AP Tune for the G37

kdo2milger

I took these 2 exerts straight from COBBS stage 2 notes for the G37

With HFCs, and CATBACK a +11.0% HP / +5.7% lb-ft was gained and the stock Intake was used as opposed to a CAI system.

Will these same parameters apply to the 370z once a stage 2 is released as well?

Exerts below;

"This calibration is designed for a full exhaust system including high flow catalytic converters. YOU MUST USE THE FACTORY INTAKE SYSTEM ONLY. NO OTHER AFTERMARKET INTAKES ARE CERTIFIED COMPATIBLE WITH THIS CALIBRATION. Running ANY aftermarket intake system has the ability to compromise the performance of our calibration and possibly compromise the engine. The Infinity G37 & G37S intake system flows very well and promotes a laminar air flow across the MAF sensor."

"Hardware such as intake systems, headers, and catless race pipes can skew the MAF sensor signal and/or create a dangerously lean fuel curve. This calibration has been established to run with the stock intake system only."


A Laminar air flow systems contains three basic elements - a blower, a high efficiency air filter, and a plenum. There may be variations on this idea - many blowers, many filters, and very large plenums, but all have the same basics. The flow is called laminar because the turbulent air upstream is changed by the filter into a straight-line flow off the downstream face of the filter.

?So judging from this concept a straight-line flow in the stock plenums is more efficient than a turbulent air flow created by CAI systems?

Interesting. It's recommended to get a protune if you want an aftermarket intake on the Subarus. It's worth getting a tune anyways but I wouldn't throw an intake on with the generic OTS maps.

Hopefully you can use a intake after a dyno tune with the Cobb AP.

I have a question about this, also... Can these Cobb AP maps for the manual '09 G37S be used for a manual '09 Z. The engines are identical, correct? Or would the ECU's not allow for compatibility?

seems to me the mapping will be different within the 2 ecm's.

cobb should have 370z mapping by now.

i know you can email them you're map and they will build a tune specific to your ecm firmware version based on mods that you tell them you have.

course you have to have the cobb tuner to download the map file to the tuner from the ecm then upload it to a pc and email it to cobb.
