running rich

JMac88 · 11-03-2010, 08:06 PM

My mods are in my signature. I would think with so many free flowing mods I should be running lean?

My idle seems to be anywhere from 13.5 to 14.5 and at WOT i seem to be hitting 12 or slightly lower.

When i installed every mod, i always made sure to do a proper reset of the ECU. Is it possible that the ECU is now over compensating for the mods?

Input would be appreciated.

If anything you should be running lean with all the breather mods, if you're running rich you may have a leak somewhere?

Have you considered having your 370Z dynoed, and a proper ECU tune uploaded to accommodate your mods?

This could be possible as I know i have a small exhaust leak. I was unaware that it could play havok on the ECU like this?
