I'm looking to do this as well with my '14 GSR. Thinking of adding an ETS intake and UICP.

Could I get by using a Cobb AP and changing the MAF scaling table and load calculation tables to the ETS intake values in ATR? I know it's not ideal but it could work for an extended amount of time, right? At least until there's a tune involved. Am I thinking of it in the right way?

First time poster and avid evoxforums reader since joining. Thanks for all the great info on the site.

Your thoughts are correct but I would suggest multiplying the stock MAF curve by 1.025 for the ETS intake instead of using their published scaling. That will get you closer on the top end (which is more critical) at the sacrifice of the low end being a bit rich in places.

COBB's published MAF scalings need some work...

You'd be better off keeping the stock MAF scaling than to change to one with a leaner top end (lower g/sec values at high voltage).

Thank you, UT_EvoX.

I just purchased an ETS intake that is currently en route. I already installed an ETS UICP.

Here's my plan.. Correct me if I'm wrong. I'm still very new to this stuff.

Install the intake and multiply the stock MAF scaling table by 1.025 (UT_EvoX's suggestion) while changing the load calculation tables to the ETS intake values in ATR.

Does anyone else have input on the situation?

The plan is to safely operate (with these adjustments) and cause no harm to the car until I get all the necessary parts (exhaust, EBCS, etc.) for a pro tune. I'm looking at 6 months before I get all of the parts.

Does this work? Or is Cobb's calibration not safe for operation? I just want some consensus before I install the intake and drive the car on the daily.

Thank you.

Just multiply the MAF scaling as I instructed. No need mess with the MAP calculation tables until you go for a complete tune.

Just to clarify. I want to make sure.

Your MAF Scaling.

Stock MAP calculation tables. Not the ETS MAP calculation tables.

Thanks. Sorry for being a pain in the ass.

I installed the AEM intake with stock MAF housing on a cat back TMR (ralliart) tuned MR and have been driving it for about a year. No problems that I know of, it gives a little more power up top in the higher revs I think compared to the works drop-in which was a little quicker down low.

the car will read different once different mods are installed. i got all of my mods installed a week before the tune. once i left Massimo Power i drove home like a grandpa and didn't drive the car until the following week on my way to get tuned. like you say there's people who say they've been running for many miles like that and others who say don't do it. personally i'd say wait til you're soon to be tuned and get the most performance out of the mods you install. after all we do want the most gains out of our parts while being safe.

The ETS intake uses stock size pipes and the stock maf, so you should be good. Those are fairly simple mods and these cars come tuned real rich from the dealer. That being said, I don,t think that the little extra air from an intake should not cause any problems. To be safe though, I would not push the car until you get a wideband in the car.

Just don't go WOT too often until you get it properly tuned, even a cobb OTS won't even be sufficient.
