OFT Tune with aftermarket airbox
Hey guys
Im new to the scene here and just installed my perrin 2.5 exhaust. Looking to go uel catted header once it warms up a bit here up north. Just wondering if there is a tune option for a catted header with an aftermarket (grimmspeed) CAI on the OFT. |

You'll need custom tuning to fix the MAF scaling. Just swap on a stock air box, way better than anything on the market.

Really really, this platform does not benefit from CAI. Other than induction noise.

Best option for my situation would be? Ecutek? Dyno tuned?

Best game plan - Get an intake (I think the Perrin CAI has the best increase in sound) Get an OpenFlash Tablet and either run one of the off the shelf tunes ( not the best but they work well enough) or get a tune from Shiv at OpenFlash |

You just need to re-scale the MAF table. You'll need a bunch of data logs, and then there's some tools available to generate the new values. From there you need to edit the tune in RomRaider, save it, upload to the tablet, flash to the car. EcuTek will be the same process except for what tools are used to edit the actual tune.

When it comes to regular maintenance, I never liked needing to break out the Allen wrenches just to open an aftermarket airbox, but my setup had the MAF sensor only accessible from the bottom of the car (got real used to/sick of removing the pop-clips). Seeing that the BRZ intake manifold is on the top of the car vs the bottom of my WRX, maybe this is a non-issue, but something that I hadn't considered until it became a PITA. As for HP/TQ gains, this is really the wrong car platform for anything that would truly benefit from a CAI. I don't ever calibrate my butt-dyno, but you won't feel anything beyond the psychological "I just did something to my car, I think I felt something different to justify the money/time spent." |

ROFL: twins stock intake IS CAI. If you want to generalize, add "aftermarket" to CAI.

Put the stock air box on. Cut the snorkel. Power, reliability and noise.
