new $EE tuning thing!

[steveo]

awesome!

so at the other end of the spectrum from our fancy new windows 10 machines, i just tried the new beta on my netbook - a relatively old and slow intel ATOM with xp sp3), and although it worked, things did not go well.

it seems qt5.5's timers are different than qt5.4 somehow (or maybe the serial interface is faster or slower?) first thing i noticed is that i seem to have lost a few records per second of throughput, which speaks to some kind of timing issue.

then flashing, it failed during the erase stage, which is a horrifying thing, but luckily my flash routine kicked into recovery mode, increased serial delays, re-executed the erase program, and managed to salvage the situation. still doesn't explain why it happened in the first place.

i'd be interested to see if people with faster computers have this problem with the new beta (which uses newer QT libraries)

i might have to roll back to QT5.4 but considering the windows 10 issues, i'd rather stick with the current branch..

I ran the 4.0 Beta 8 installer, then asked it to run eehack.exe. It says
"Unable to execute file: C:\Program Files(x86)\EEHack\eehack.exe

CreateProcess failed; code 740.
The requested operation requires elevation."


UPDATE seconds later - I turned off "compatibility mode" and "run as administrator" and then clicked on eehack.exe. It started right up. I'm going to try to connect to a car tonight and try the interface.

UPDATE 2: GOOD NEWS: Key on / engine off (test car is loud and it was late):

• EEhack 4.0 Beta 8 starts instantly
• Connection works well.
• Fast mode gets me to about 13.7 records/sec.
• I tried all the auto and TCC control buttons and I could hear all the solenoids clicking appropriately in the pan. I would say this functionality works, though I was unable to test what happens when I return to "auto" mode.

Nice work Steveo!

it's only happening because it's trying to launch eehack (because you left the 'launch eehack' button checked in the installer)

... and windows 10 is too braindamaged to maintain backwards compatibility and sane default security settings. god knows why it's not ok for one process to launch another process with normal windows system calls.

it does work in previous versions of windows. i can remove the option for release and users can just click the icon themselves after.

edit: i did google a workaround though, i'll try it out.

[steveo]

workaround seems to work, and i'll leave the box unchecked by default for good measure.

thanks so much, that's such a relief it's working and you're getting good data rates! at least it's just my old winxp laptop having serial issues.

one thing i'd like if you don't mind, even without a driving test, if you'd see if the gear selection DISPLAY matches the gear selection BUTTONS. im only like 50% sure i got the solenoid combinations correct as they may be stored in a different order than the display bits. im totally in the dark on this automatic trans stuff.

please also play around and see if you can break it in windows 10

Will do. The gear indicators seemed to work correctly, at least I didn't notice anything out of whack, and I would have noticed that stuff pretty quickly given how familiar I am with the 4L60E.

BTW, sent you TWO additional emails on the injectors with links.

BTW my blue screens of death in my earlier tests with 4.0 beta 3 were likely due to my serial adapter, a tripplite USA19HS. Later attempts resulted in immediate BSOD so I repaired the driver installation and no more problems.

Changing gears works, manual engagement and disengagement of torque converter does not.
Wideband looks much better with smoothing, though I appear to have a slight lag, it appears that it changes just after the gauge. Probably not enough to matter though.

Temp readings appear much more sane. I was seeing a max temp of 145F on my commute to work before the update, now it's showing 170F, which seems more likely with a 160F t-stat. Haven't compared temps to datamaster. I haven't even used datamaster since I started logging with eehack, though I guess I should have done a comparison when the temps seemed off.

On a side note, when testing the gear selection I accidentally left it in fourth at a stop light, 4th gear start was very sluggish. LOL
I was shocked that it didn't buck or stall.

i'll look into it. glad the gear selector works, though.

yeah we had to give up a little bit of response time. how the 'smoothing' really works is averaging the last 8 records or so together. if i made it a weighted average it'd be a bit less 'smooth' and a bit more 'responsive' but i think i'll leave it how it is.

Temp readings appear much more sane.

yeah that was a big blunder on my part, mis-reading disassembly. shoulda just trusted the datastream file.

oh yeah that explains a bit, your reconnecting behavior as well (clicking disconnect/connect resets the serial interface, automatic reconnect leaves it open)

That's interesting that the TCC didn't work for you Brian - I could clearly hear a solenoid clicking and unclicking when I tested that last night. What's your application? On the '95s, there's TWO solenoids that work on TCC lock, one controlling on/off and the other controlling the apply rate; I'm wondering if this mode works both of them?
