Whipple cal with headers, Cel

[v8ter]

Whos running whipples cal with longtubes? Wondering if the cel should be adressed with foulers or does it do any harm or have power loss with it on?

And what gains have you seen with longtubes at the dyno and at the track?

Me. I just used foulers after talking to Whipple. Unfortunately I don't have any before or after gains, just the dyno after everything.

Careful with foulers, you want to disable a setting in the tune that uses the rear 02's to calibrate the front 02's if you are going to add them. By using foulers you may throw them off. I don't have my laptop with me or I would tell you the settings name

I want to go to the track on sunday and I dont have the foulers yet, does it hurt to run it like that with the whipple cal?

No, it will only throw a code for catalyst inefficiency, it will not affect power output. If you've driven on them for few hundred miles the ECM should have already adapted to the front 02's new location as well so you should be good to go

You can't do that with the Whipple tune and I've already confirmed with Whipple tat the foulers are fine. I've been running them since the summer.

Are you catless?

Are you catless?

SP 1-7/8 OR LT's mated to a SW 3" LMF catback. My neighbors (and the next town over) can attest I am catless.

Their tune is not some sort of new firmware they build from the group up to be different form OEM, it's only a calibration built on the OEM software....This means if the setting is there than it can be done. The settings is under:

Engine>General>O2 Sensors>FAOSC> Set this to "Disabled"

That setting may not affect anything at first, but after a while your 02's will begin to lose their calibration and rely on the rear 02's to account for aging. If the rear o2 have been tricked by moving them out of the exhaust stream, they could throw the front 02's off. AED made a long post about this over on the SVT forums as well.

Let's try this a different way.

It's a CARB tune. There will be no shutting off of the rear O2's.

Like I said, I am happy with Whipple's explanation that my setup is fine.
