Just throwing a question out there to whoever is able to answer,

I just wanted to know if it is OK to disable L.Trim (make l.trim value = 0) after final tuning has been completed and s.trims are within an acceptable low range at both low and higher speeds?

Cruising around at town/city speed (typically 50-60kph) my s.trim values are within 0-5% at most and at freeway speeds (100-110kph) my s.trim is between 0-3%

Is there any potential negative side effects or concerns I could experience by essentially disabling L.Trim on my tune?

There's no real advantage using long term fuel trim, so you can disable it.

Thanks for replying Hondata :), so with no advantage of long term fuel trim with my tune I can safely assume that disabling it wont cause any damage? My S.trims I believe are pretty acceptable after back to back tuning and datalogging now that it is within 0-5% range for the most typical kinds of speeds and conditions my Type-R does but I just wanted to be 100% sure that I can rely on the S.trims to handle any abnormalities that could potentially show up over time (if any) especially if I decide to take it for a long 1+ hour drive on the freeway.

I guess basically what I'm trying to ask is, with L.Trim being disabled and with good S.trim values at both low speeds and constant freeway speed, can I safely assume that I shouldn't have any problems with not having L.Trim make any adjustments over a long distance of driving?

I suppose if you have the time to clarify (or if anyone else can chime in on this) - in both an ideal properly or an un-tuned map what significance does the L.Trim values play on both kinds of mapping?

If in one example the tune has been correctly setup and the values are acceptable, does L.Trim offer anything other than disadvantage? and likewise, with say an early revision or basemap tune, could L.Trim potentially assist / make the tune worse by having it enabled in both cases?

If anything I'd just like to know if I should have any concern with taking my Type-R for a long drive whilst having L.Trim disabled
