Hum, 100 posts. 100 posts about random crap, but 100 nonetheless.
Speaking of random, I was (am) attempting to make my own version of the MegaLogViewer for Megasquirt. In this attempt, I happened to notice that my Z31 cranks at 280-325 or so RPM. This is not a big deal, it’s just that I have my MS box set to interpret anything at 300 RPM or below as “cranking”. It applies a whole different fuel factor to the engine when cranking versus running, which is 301 and up RPM.
So, this could explain why my car is hard to start sometimes. One of these days, when I’m not busy studying (which consists of mostly me running errands and otherwise not studying), I will up the cranking RPM to 350 or so and see if I can finally get some positive feedback from modifying the cranking pulsewidths. Before now I was pretty much shooting in the dark, with some settings working some of the time.
Here’s a screenshot of my program so far. It’s in C#, and it’s horridly put together right now. All it does as of now is load files (up to a million records long, anyway), parse the data in to memory, and draw unscaled graphs of the first x records. Where x is the pixel size of that picturebox control you see there (the actual graph):

The ticker control at the bottom is eventually going to “scroll” the graph. Right now it does do something, it scales itself according to whatever file is loaded (thus, however many records are loaded), but I’ve yet to implement the scrolling feature.
100th Post! (…and Megasquirt Woes)
