LOL. And why is that, may I ask? Too funny . . . Btw, I haven't tried the Motul yet (I'm only at 3000 miles and did my first/last change at 1800 with the Nissan Ester). But wstar has already switched over to it and he likes it.

Why not just pm AK and have him remove you...

It's more dramatic this way.

Does triggering a code damage the engine or affect performance? I plan on installing a HFC, but I hate to deal with all the potential issues mentioned in this thread

No, it doesn't.

Another question - I have an automatic transmission and wondered if adding power will potentially damage it. How much Hp is too much for the A/T?

shumby · 07-22-2009, 07:55 AM

bolt on will not hurt the auto tranny. you will never see any HP that will screw it. a stage one turbo is safe on the stock tranny.

Ok so I've read through the whole thread, but I have a question on all this (during these note that I live in NJ who is pretty heavy on the emissions testing)

If a person were to go with test pipes instead of HFC's could they just clear the CEL and prevent it from coming back on with a program such as UpREV by having it de-activate the second O2 sensor (to prevent any problems when getting inspected)?

I'm trying to figure out why everyone here (who almost everyone wants max performance N/A for now) are going with HFC's instead of test pipes.

It's going to vary by state, I know nothing about NJ. Here in TX you can generally get away with reprogramming around the CEL (as in, actually reprogramming the ECU), but just "clearing" it with a simple code-scanner won't usually cut it (because the OBD-II info the emissions testing place looks at shows whether a complete drive cycle has been performed since the last code clear, and they want to see it showing completed and free of codes). There's no inspection for the first 2 years on a new car though, so in TX you'd have two years to find an ECU solution before you ran into that issue.

Technically, even in TX, I think test pipes are illegal on public streets, but if you can suppress the codes with an ECU flash, you'll probably get away with it since many inspection places only care about the OBD-II readout.
I went the HFC route because at the time I was making the decision there was no ECU flashing available for the car at all yet, and I didn't want to be fighting clearing the codes all the time until one became available (having a CEL thrown randomly while you're driving and not knowing what it is sucks, gotta shut down, get out the scanner, confirm it's the O2, clear it, wait for it to happen again...).

Once I get an ECU flash going that can suppress the CELs effectively, I may decide to swap my HFCs for Test Pipes at that point, if the rasp isn't too bad (maybe resonated ones would help).

Can UpRev or Cobb effectively suppress the CELs? Because then I would just go with test pipes. Maybe i'll weld some shields or something on to make it look like stock cats in case they decide to take a look under the car (which they usually do a quick sweep with a mirror)
