Negative ltft (-9%) after takeda momentum intake install

[vroomgo]

I have a 2024 integra a-spec tech. I have a ktuner with phearable 1.5r. I decided to install a Takeda momentum intake and since then, my ltft is hovering at - 9%.

Is it cause for concern and how can I remedy this, outside of going back to stock if possible?

Thank you!

The LTFT is pulling 9% fuel, make sure you don’t have an air leak around the Mac or connections, as the car learns it will go down to. What are the stft? If they are wildly high or low then you definitely have a leak. Could be the learning phase after the change also.

Could be ecu learning. I just checked all over and my install looks pretty clean, no leaks to be seen.
The stft oscillate between - 10 and - 5 % most of the time.

I tried to look into maf scaling but its way above my skill level.

Thank you for your help!

Let it run for a bit and relearn all the trims. The BMWs and Minis do the same thing. Worse when the fuel switches from summer to winter blend. We end up just resetting the engine and trans learned adaptations, car feels new, relearns new parameters.

Ok, ill let it run for a bit and keep monitoring
Thank you!

This intake, especially early production versions, are known to leak around the MAF sensor. I'd check that out for sure.

I think you're right. I went and double checked and one of the screws wasn't tighten all the way. I'll go for a drive later on and see if things improve.

Thank you!
