I have noticed that narrowband TT225's have LTFT issues. A lot of binaries have LTFT's disabled via NOLRA. When enabled, they don't work properly, which must mean there is something wrong with the adaption settings.
Has anyone else run into this?

Well I can tell you that 034 motorsports and unitronic get around all this by converting to wideband front 02,
Its pretty easy and a hell of alot better.

I think the rear 02sensor could be what is causeing the ltft problems your talking bout.
I started a thread awhile back discussing rear 02s and ltft.

Not rear O2. I confirmed that binaries with working LTFT's have 08 for NOLRA while the ones that do not have working LTFT's have 04 for NOLRA. |
