Will the check engine light lit up if i install an intake system?

[Diz86x]

Hey there ,
I was planning to buy a Takeda Stage-2 Pro 5R Intake System , but after i saw the reviews i was affraid i loose my warranty because of the check engine light .
Help pleaaase .

It may or may not.
I know that isn't much of an answer but unfortunately there is no guarantee one way or the other.
If everything is done right it shouldn't but you won't know until you try.

Its highly unlikely you will get a CEL if you install the intake correctly and don't damage MAF sensor.

You won't loose your warantee completely for installing an intake or even if you get a CEL code due bad install. However they would be entitled to charge you for working out your intake is the problem and they could deny you engine warantee if for example they could prove the intake had a leak and sucked in dirt or made engine run lean causing the engine failure or problems.

Intake such as Takeda will upset you maf scaling, I have done a couple of takedas and the scaling is off about 15% at lower rpm.

Honestly their is sod all power in changing an intake save you cash, just put in a drop in filter (dry type) in standard air box you will pick up a couple of hp and no issues with maf scaling ect, easy to swap out for service/warantee work.

@steve99 is the man, full stop.

On topic, my AEM intake fucked with my MAF scaling, ditched it shortly after I posted some logs and was told I'd need to do scaling. Sold it for like a 20 dollar loss, and forgot about an intake.

Just pull the negative battery cable while you install so any differences should be relearned as new data by the ECU and it will always expect the changes. If the CEL comes on at all.

ECU is constantly learning fuel and knock corrections, removing battery will achieve nothing extra other than resetting cel codes.

Resetting ECU or letting it "learn" will not fix maf scaling errors introduced when intake is changed

Resetting ECU

In general resetting the ECU will achieve very little other than resetting any Diagnostic trouble codes and hence CEL light

You better off investigating the cause than just resetting the ECU as you are erasing any diagnostic info.

The ECU continuously learns fueling information and ignition timing corrections so it will accommodate changes in fuel octane rating or 10 % ethanol fuels or minor exhaust/intake changes within its learning limits without a RESET.

Resetting the ECU will just set these back to default, and it will still have to learn, it will learn these changes anyway without a reset and end up at the same point with or without a reset.

Learning is fairly quick usually in minutes, it actually learns quicker if you drive non-aggressively (steady or slow throttle movements) at varied RPM and loads.

You can reset by removing battery cable or ECU fuse for a few seconds.

The ECU is reset if the CEL code has triggered Limp Home mode (low power mode rpm limited to aprox 4000 , base timing A and rich fueling used). When you reset CEL code to bring ECU out of limp home ECU is reset. Not all CEL codes trigger limp home mode.

Remember you will also reset all the learned fueling and ignition advance tables and the ECU will need to relearn these.

Also the ECU will perform initial diagnostics and calibrations of Cam VVT and throttle sensors/actuators after a reset. See above re minimizing issues after flash or reset
