Installing Intake question
Im debating whether installing the intake myself to my IS250 with friends or at the dealership. the thing is that the dealer told me they needed to reset or do some configuration with the computer in the engine, and I am not sure how to do that or what they mean?
my friends say all you have to do is disconnect the battery or remove a fuse. any advice would be appreciated!
thank you

it's an easy 20min DIY job...........so do that and you can also learn your own car better
the dealer just means to tune to intake since your air fuel ratio and everything is messed up now that you're intaking more air........but it's just an intake, it doesn't really matter at all......you might get a slight drop in mileage without tuning it, but this won't matter either bc for first couple weeks your mileage is gonna drop drastically anyway from you constantly flooring it to hear the beautiful new stereo system

Do a search on this forum and you'll find plenty of information on how you can install the intake by yourself and reset the ECU without disconnecting the battery. I thought I was gonna need help installing it when I got my intake, but I'm glad I learned to do it myself.

All you really have to do is disconnect the battery and reconnect it later. This will reset the ECU. There is also a way you can do this without removing the battery, just by removing a fuse and putting it in again. That's all you have to do, the car will automatically adjust itself afterwards.

The ECU is constantly learning, so it'll learn any needed changes as you drive it, even if you leave the battery connected during install.
Disconnecting the battery isn't an awful idea just in case you screw something up and short the MAF connector or something I guess... but there's no "tuning" reason it needs to be done.
But I've installed enough intakes I didn't bother to touch the battery when I put my F-sport on, there's really no need to if you do everything right.

Installing Intake question
Thank you all,
I guess Ill locate the fuse remove it and put it back on after its installed. I need to look at a DIY guide for installing it, this would be my first time.

Like Kurtz said, the ecu will learn over time anyway. If you reset your ecu, it will just learn a little faster.
Honestly though, we're talking about power gains of MAYBE 5whp, which you wont necessarily notice. Just install it yourself and dont worry bout it.
