Xmas tree errors on datchboard

[NolimitSi]

Hello You all.

I have a 2018 Si Civic. I bought car with 15miles.
As soon I bought car I started tunning car with aftermarket parts like. Injen intake, ktuner, stage 1 and hondhack head unit.

Now I have emission problem, hills assistance failure,brake failure, steering wheel.,brake problem.

I just replace my fuel injectors with dealership parts last week. (Wish by the way they are discontinued by honda) and the warning light came back again.

I remember when I install ktuner and flash ecu for the first time this happend but went away after 30 minutes driving.
I feel like the ecu is not flash properly I already got the ktuner back to stock and I still have errors.

Please help! Thank you.

I'd go ahead and reflash it again. What error codes(s) are you getting? And think about ditching the Injen intake because it can skew fuel trims quite a bit without custom MAF scaling.

I have error p0172

When you said to ditch the Cai is it because of brand?

when you said ditching the intake is it the brand or the maf?

I can buy different brand is necessary.

I'm setting up an appointment on loc shop to make me custom a tune. Hopefully is not that expensive.

I'd start by making sure you hooked everything up correctly from installing injectors.
