Ohhhhhh.... it's simple, but quite clever...

Actually, FREEBSD owns... I'm using FreeBSD,which is what macos x is partially based on.

AkumaKuruma

freeBSD is good yes...OSX is good because its based off of FreeBSD/Darwin (stability wise). but apple itself SUX cuz of stuff like the latest java security patch they did that makes it so half the stuff relating to it dont work(yep...its secure if the java stuff cant run at ALL)

are you running aftermarket fuel management?

at 3900-4000 that's where the 5th and 6th ports normally come on, and that's also AROUND where the secondary injectors usually come on. You could be hitting a lean spot there... I noticed on jasons's car at full-throttle, when the secondaries come on, there's about .2 seconds where it spikes lean before the extra fuel from the secondaries gets into the engine. I'm assuming at this point it's doing that because the aux ports aren't opening. yet...

In other news... I think I nailed the low-rev fast throttle blip problem. There's a bug in the firmware that only gets triggered when you have spark advance set close to the trigger angle (in my case, trigger is at 0 deg (TDC) and the bug triggers at advance of anything less than 3 it seems). I'm going to work around it by retarding the CAS by 5 degrees, and then setting everything in my advance table to whatever it is now +5. I found this problem by restricting the vacuum hose going to the MAP sensor, so when I rev, the part of the spark table that's causing the trouble never gets hit... and when I did that, the engine revved beautifully from idle (it revs very nice anyway above 1000 rpms).

If there's time after work today, we'll be getting jason's cold-start fast idle and megasquirt controlled idle speed working. So jason will be able to do things like turn on his AC without stalling the car. We'll also try to get his electric air-pump/aux-ports/VDI working. This is all of course if there's time...

Not with MacOS X... geez u guys are living in the '90's

It's nothing you can't fix.... I've never had a problem running anything, java or not, on my mac laptop...

AkumaKuruma

ive had a few problems with programs on OSX myself. Mind you this was back around 10.1-10.2 so they may have fixed it since. GNU/*nix based programs run fine though.

i'll stick with true FreeBSD no matter what hardware the system really is. still trying to get damn X to work with my LCD monitor on my Ultra5. damn thing freezes the whole system with NO error message recorded to the log. works fine with CRT (and yes i made sure to change the display settings for the monitor to those for the LCD.

muythaibxr

Yeah, I'm running 10.3.something (I forget what the latest security revision is)...

I'm actually going to buy a usb-serial adapter, and try to get MegaTunix working on my mac... so I can use my mac laptop to tune the megasquirt.... MegaTunix apparently has pretty OpenGL graphics for some of the real-time tuning screens.

AkumaKuruma

graphics *****

hardcore tuners use CONSOLE output

muythaibxr

ACtually... have you ever seen any of the tuning software... I think the least advanced software I've seen was running on DOS, and that was even graphical... I think it was for Motec...

AkumaKuruma

nah..i think i personally would want to see 3-d plane representations of the graphs to help with tuning. just seeing numbers never really helps. need multi axis graphs just like what you showed me on the MS tuning software you had. RPM vs load vs A/F ratio.

that DOS one reminds me of that tuning software that runs off gameboy.

muythaibxr

Here's what the tuning screens in megatunix look like, they look similar to the windows MegaTune that I've been using on jason's car... but they're openGL, so I'd assume they update a lot faster:

AkumaKuruma

that software does look a LOT nicer.

Yeah. I'm lookin to get another beater Dell laptop so I can have ACTUAL serial ports...

I never did like the USB-Serial converters.

I'm also looking at porting Megatune to the Gameboy... I found an article in a magazine called "Nuts and Volts" about how to use the serial output of the GameBoy to control a scrolling LED dot matrix display...

It's synchronous, so it has a clock pin... And it's bidiredctional. Maybe pipe it into a buffer and through a PIC Microcontroller or something... Convert to RS232...

There's C compilers for the GameBoy, and flash cartridges available... And there's USB interfaces so that one can read and write to the flash cartridge...

Or maybe adapt a cartridge so that Megatune resides in onboard flash, and it'll have a CF or SD media slot...

muythaibxr

Good luck on that, MegaTune is writtin in VB... not C... and relies heavily on Win32 being there... in other words... you pretty much can't do it.

You might however be able to write your own tuning software for gameboy.. but I'd much rather just use a laptop...

I only need the USB-serial adapter b/c my *nix laptop is really a mac running MacOS X.

This is what I want for a gameboy:

So is mine... 15" G4 @ 1GHz Aluminium PowerBook. 60 GB Drive, 1 GB RAM, CD-RW/DVD combo...

I was looking at the GB Scope too, but for that cost, I can probably get a dedicated portable scope.

Perhaps Megatunix... I dunno. Writing my own software shouldn't be THAT hard... (Yeah right... This coming from the guy who crashed the computers in High School CS class writing Tic-Tac-Toe...)

muythaibxr

The GB scope will be like $250 said and done if you get an old used gameboy as the display.

I've never seen a portable oscilloscope that'll do what that gameboy one will for less than $1k... otherwise I would've bought it already.

Those are just the ones I have floating around in my head... I know there's more available. I'll have to go through the magazines and catalogs at work and see who sells others.

EDIT: I just realized, that the one from All Electronics is the same as the lower end Ramsey one... (Ramsey has two models available...)

muythaibxr

Neither of those have dual channels... to do what I'm trying to do, I need to be able to see 2 wave forms one above the other at the same time....

DarkAngelKamui

This one's for a lot of you:

AkumaKuruma

i think it fits

Pele

Picky, picky, picky...

muythaibxr

heh idunno man... the point of getting one is to see the relationship between the tach signal and the spark advance signal on stock ignition systems ... so I can use stock ignitors with megasquirt... but I can't see that relationship w/o a dual channel scope... so anything less is pointless..

I agree with it on a certain level. You just gotta be a good shopper.

Buddy of mine has a 500MHz G3 Powerbook which can still edit video clips and such... My 500MHz P3 Dell laptop (Same RAM, Same Drive space, etc.) couldn't do that (iMovie vs Adobe Premere)... So when it died, I bought an Apple, simply because it'll have a longer useful life.

The iPod, I agree is a well overpriced thingit... I think the Zen or one of the Samsung players is better for the $...

My laptop vs my roommate's laptop are fairly comparable in the amount of time it takes to get **** done. (Various Photoshop effects, encoding and compressing a movie, etc.) His is a 2 GHz P4, 512MB/60GB Gateway. My laptop had 256MB of RAM at the time... Though his was probably slowed down by the spyware and ****... Mine was slowed down by having no RAM...

I dunno... $1800 a year and a half ago didn't seem like such a bad deal.
