Gents,
I'm well aware of ecuproject and trionictuning websites, but for some reason prefer TSN. And I believe I'm not the only one here who's got Lawicel can-usb adapter.
So have you noticed that some RAM segments are quicker to respond (i.e. to read, to refresh, to retrieve date from) than others? I'm not talking here about flash images, but RAM. And the difference is quite significant: up to 2x times (see the shot below, with -+20% threshold for the mean value it gives x1.5 difference: 1.2/0.8=1.5, 1.2=1+20%, 0.8=1-20%. Green are fast segment, red slow and yellow correspond to batch mean value +- threshold)
I came up with a small benchmark utility which measures response timings for different RAM segments. If anyone gonna try it with his own T5.x ECU, I can post it somewhere onto the web.
Zig
P.S.
Yep, I later noticed that typo and corrected 'threshold' label, but it happened after I had uploaded that screenshot.
