Will be finishing off the install of my new FIPK tomorrow afternoon. The instructions mention nothing of it but I have a little voice in my head saying I should reset the ECU? Is this needed or are the voices playing tricks on me again? I will be disconnecting the battery negative terminal before installing - is this in effect an ECU reset?

 

If it's going to be off for half an hour or so - yes.

 

Please let me know how the sound compares to OEM airbox/lid off, I had a HKS RSK on my first S, which was night and day compared to the lid off airbox setup.

 

The battery disconnection for the installs will reset the ECU from what I read before doing mine. What I found when I first fired mine up post installs was the idle was dropping to about 800rpm and sounded it was going to stall, but after a short drive and a second start it sad back to normal, so I assume that's it recalibrating.

 

3 Cooling fan cycles whilst idle resets it - if you're going to fit the K&N etc etc you might want to clean out the throtte body and IACV and do a complete job.

 

It's best to let it sit for a while and learn the idle, but it figures itself out after a while.

It's not a mod where you need to disconnect the battery / ecu reset, but doesn't hurt.

 

Brilliant thanks everyone, will dissconnect terminal for at least half hour.

Tangovtec - it sounds amazing, much much much better tone than rough lid off vacuum sound + no heat soak! Search for a thread by DanWebster I think it was, best sound capture so far.

 

make sure you have your radio code

 

Aftermarket radio but made that mistake before lol I will listen to filter anyway, speakers are useless with top down let alone with fipk!

 

You can hear it in some of my video.

Still think it's better than my AEM for noise!
