Hi...

I don't see any attachment of an APS CAI MAF Scaling for a USDM 2.5L STI...???
Can you please re-attach this table for me?

Thank you.
M!

I know these are great intakes and many use them so I thought I would share.

THis was developed on several cars with WBO2 tuning in downpipe and getting all fuel trims <3%.

Fuel used was 93 octane, stock STI side feed injectors.

Usual disclaimers apply. If you don't know what you are doing, then don't do it!

How comes when I compare your APS MAF scale data, they are the same as the Stock Map MAF Data?

I installed APS 65mm Amsoil Airfilter on my 05 STi, (all else are stock, like stock injectors etc), but I still got A/B/C areound -12%, -6%, -9%. I just re did my MAF again.

Any thoughts? Thx

Wow, I never noticed that. I copied in the MAF from pre-tuning. Oops! I apologize to all the folks who downloaded it. Here is the correct one for the 32-bit.

New table located here.

I was using the one for 16bit that you posted. Do you have any input for fixing it. Your changes helped out a lot.

BTW the knock is a loose heat shield, fixing this weekend.

Most of us do use the APS 70mm CAI, w/ good tuning it can give us good/stable hp output @ the high rev band 6 to 7k rpm.

The calibrations I posted are for the 65 mm version, not the 70 mm. I have tuned a 70 mm one also but this was on a car with injectors and meth and I tuned for everything all at once so I would not release that one.

Ok, this may be a super obvious noob type question, but why is it on my Forester MAF Sensor Scaling table I cannot get MAF sensor voltage above 4.69v?

Edit: lol, my bad. WRX vs STI MAF Resolution...

Have you guys had to modify the MAf IAT comp table with this intake? I got my maf dialed in perfectly during the middle of the summer. But it seems like now that temps are dropping slightly, im running leaner.

Also, I believe the xls that team scream posted has the stock 06-07 wrx maf scaling. I was going to compare his with mine and stock, and his and stock are the same.
