Hey Everyone,

My name is Matt from South Florida and I've recenlty gotten myself a 2016 WRX. Beyond happy! I've recently installed the ETS intake and I'm currently running the Big SF 93 oct map. I couldn't find an "ets specific" map, so i logged my numbers for about 200 miles worth of driving and have yet to see an issue. I've done constant pulls and have seen performance gains, but i haven't seen problems with AFRs or knock. So should i keep this going or.....?

Thanks!

This topic has been covered in depth across multiple forums. I personally wouldn't because the tables are going to be way different but you do you.

Use only the map that specifies the exact intake in the notes.

I'm new to forums and searching so i couldn't find it..my bad!
It's just not as simple as having no knock. The ECU starts messing with timing and fueling to prevent knock. So you get into a situation where it's adding too much fuel and pulling timing and you can foul plugs that can lead to misfire.

Last I saw ETS provided flow analysis for their intake and it supposedly flowed the same as the stock box and intake. I'm not a fluid Dynamics expert so I can't speak to how realistic their claim is.

would you happen to know where i can find the ETS map?
I've not seen an off the shelf one so you would need to contact a tuner

I guess my question now would be: what's the longest i can go without contacting a tuner? Not saying I'd wait forever but a rough timeline would help

I wouldn't drive the car at all. Engines are expensive. Labor to replace them is just as expensive.

Contact ETS or reinstall the original intake or get a custom ECU calibration.

I contacted Eric from Torqued performance and he sent me a custom ETS map within an hour. paid $150 and everything is running just fine. Peaked at 20psi and i'll be sending him the logs to review them later. I did notice that with the big SF map, when i was doing hard pulls the engine would buck a little bit...now that isn't happening with the new custom map. Thanks for the advice!

Good. BigSF intake is a different MAF housing and will cause skewed MAFv calibration.

You might not have "noticed" anything previously, but it is likely that the car was running lean in OL due to underestimating the intake airmass.

Here is an example of a scale factor multiplication I used when tuning my bigMAF housing:
