Also does anyone know if the forge motorsport turbo inlet capable of throwing any code? Rather just not risk installing it and having to uninstall it since im in limbo waiting for ecutek on the 25s.

 

I have the SXTH version of this, and it has remained in the box because of three reasons (bought it on sale for Black Friday):

• I have yet to see anyone show any sort of gain with turbo inlets when not using the stock intake (where they do make power by relieving a bit of a bottleneck).
• The piping is made out of aluminum, at least mine is, which is going to heatsoak like crazy right above the turbo and drive IATs up over the stock thermoplastic piping
• MY25s are already so damn sensitive to the P2C90, that if you having a working aftermarket intake already (I do), it's advisable to not mess with it given there is no software fix like there is for MY23/24

 

P0101 means the the signal from the MAF is completely out-of-spec. Just out of curiosity, is the Forge intake's filter media oiled? I've had oily, greasy K&N filters foul MAF sensors on one of my previous cars and made it throw a CEL. If that's the case, maybe try to put the OEM panel filter with the Forge top box and see if it fixes it.

 

Seems to be dry. I'll put my current Toms filter in with the forge carbon top and see how it responds.

I have a 25 GR Corolla with the full HKS intake with full carbon enclosure. I get the P2C9000 code. I have the SXTH fix and can still get the code if I go over 4k rpms and boost. I also tried the MST V2 cel fix and that also did not fit it. The SXTH one seems to keep the code away the longest between code setting. So far there is no Toyota software update for the 25 model year, probably not for a year logistically. Also ECU Tek is not supported for the 25 model year yet either.

For your code it seems more likely the MAF is dirty. Or the tube that the MAF goes into now that it is new is the problem. Could be the MAF is installed facing backwards or more likely the "clocked" location of the MAF is wrong.

I ended up fixing it by leaving the battery disconnected overnight. Now its just throwing p2c90 which is still annoying as they have advertised the forge to not have any CEL. They must not have R&D with the 25 ECU yet.

 

For those of you getting this code.

I thought maybe my big mouth with the forge might've been enough to trip the p0101 with a 20%~ volumetric increase. But the ECU just needed a hard reset.

 

so what happens when the intake code is thrown? you just get a message and the car still acts the same? Ive been waiting on not doing an intake due to the whole CEL 25 model year thing.

 

P2c90 nothing. Just an annoying message over and over. P0101 puts the car in limp mode.

 

Just a interesting observation. Getting p2c90 with the forge intake seems pretty rare as it doesn't mess with any of the pcv hoses.

I wonder why that is outside of the 25s being tuned differently than the previous MYs. The forge intake didn't have any issues with 23/24 MY on stock tunes unlike most other intakes.
