I have a 2007, which works fine. Well, except for a very slight flickering of the dash at idle. Higher RPM gets rid of it; no use or non-use of accessories (like A/C) makes any noticeable difference. No CEL (or any codes). Voltage is 14.2. Changing batteries does not get rid of the problem. Tightening the the battery leads does not affect anything.

It's a car fully-prepared for STR autocrossing (meaning, for the purposes of this discussion, re-tuned ECU, using a Hondata). The onset of this slight flickering did not in any way coincide with any tuning.

My first thought, when I saw it and found that the flickering stopped when I revved the engine, was that the alternator is going bad. But the perfect voltage suggests that that isn't the problem.

Any educated thoughts?

Thanks.
