Header actually made for an 2.5i

Who was flaming? I was informing other inquirers accurately and politely. I never once said anything negative or disrespectful toward anyone in this thread. i am just trying to provide facts that may be useful to current readers of this thread as well as readers in the future. And this technically isnt the correct forum for getting together a "group buy" or even gauging interest in a product that will be sold. And there are several posters in this thread alone interested in this idea if it were an EL design, so don't assume just because many people ask for UEL to get the rumble that there isnt as many who want EL for the performance gains. Don't be an ass.

The only issue is that if it is relative to some sensor input, for example, and that input is now off or out of range because the sensor was removed, the ECU may react to that input as if the data was accurate, which may have some response. The typical scenario with Subaru is the removal of the rear o2 which will cause you to run richer in closed loop.

Thanks, Tea Cups, I did not realize that there was a difference between the 16-bit and 32-bit ECU's as far as disabling the CEL's and the effects it has. I just remember this being said in either here or the RR forums.

EL or bust!

For you free marketing study, only will buy EL for me.

Not to hijack this thread. But since CEL is often part of these mods. I want to ask the expert...

Hi Tea cup,
If one disables the engine misfire codes caused by light weight flywheel, will s/he still pass state inspection? This has always been unclear to me. Some say the rr will only remove it from lighting up in the car but still stored in the ECU. Some say the ECU will stay "not ready" so not passing, others say if the state uses the OBD connection for data, it will pass. etc. Can you please answer this? My car is 07 2.5i.

you could always just reset your ecu right before getting your car inspected, i have a lw flywheel, and before i disabled my cel, it would only come on ever couple hundred miles

The thing to realize with readiness tests is that they are not all entirely CEL based. Each readiness test is based on a number of factors, including but not limited to CELs. So, even if you disable all the related CELs, this doesn't mean that you will pass a particular test. I haven't messed with the individual readiness tests enough to determine the exact criteria for each test, so I can't give you specifics. However, for the 32-bit ECU, your best bet is to disable all related CELs. Misfires are a special case as you want to disable P0301/P0302/P0303/P0304 as well as the two P0000 codes.

Also, remember that the readiness tests are based on drive cycles. You have to drive under certain conditions in order to hit a drive cycle and certain number of drive cycles are required. Resetting the ECU resets the readiness tests and you will have to do it all over again, so don't do that right before the test.

I'm glad I didn't buy a Legacy when I had to pick which 2.5i, the aftermarket support for Legacy guys is there, but it's not as vast as the impreza crowd.

bump, for a good product coming for you legacy guys!!

[Pawlwawl06]

...and I'm glad I didn't buy an Impreza 2.5i b/c they look so weird without a hood scoop to each his own though

[bcware]

did you seriously just bump this old thread just to leave a comment that has nothing to do with the thread even remotely?

[Ogden]

EL and fitment for an '09, and I would consider buying one. Still need many details though. Any progress?

[funky monk]

doesn't sound like it, too much banter back and forth about EL and UEL
