Rev Limit Change == Die

[adrianpike]

First creepy squat moment in a loooong time tonight. Sitting in gas station, on the way out, decided to put the rev limit a bit lower for some entertainment. Set it to 3500, hit burninate, and dead, just as smoothly as if I had flicked off the MS.
"That's funny", says I, and I crank her. And crank. And crank. Nary a sputter.
Now that the humor is gone from the situation, I lean over to the laptop, and notice that MS has disappeared from the map. Check cable, plugged in fine, hmm. About now I'm figuring I'll push it over to the side of the road and reflash or something, when I figure I'll reset the squats just in case.

Power off, power on, crank for 10 seconds, and it fires back up.

creeeeeeepy. good thing I've got AAA. :omg: Anybody else had this happen to them? Known bug? msns-e 029q, IIRC.

when i first did the msnse on my waingoon, I forgot to set the rev limit higher than 2500. This problem had me stumped for hours untill i did the review tool on mega tune. I know this has nothing to do with your problem, but thought i would share

[PetesDustyVolvo]

029q is cursed... or so I thought but I was wrong...

That said, I think there are some known bugs and I'm running 029v now

Honestly? whenever I hit "burn to ecu" I have a moment of fear as the engine bucks, stumbles, then comes back to life. I know I should be able to do it, but it scares me every time.

Never had a problem with a rev limit change... I think there are some things you should never do with the engine running, but I can't recall them right now.

Reloading an entire msq file with the engine is running is bad juju... I know that.

When my laptop was causing MS resets, burning anything to ecu had a 50/50 chance of success. Because the resets were 5-10-15 seconds apart, if I timed it right, I could burn something without the MS saving a boatload of gibberish.

Once when i first got my car running last year i was driving along and we had gotten a nice ve tune. So i told my friend to click burn to ecu, he did it, and megatune crashed.
and MS died, nothing happened at all it just died 100%, so i pull into autozone, turn the car off and back on, and it like floods like a mofo and smoke pours out of the exhaust and the autozone guy made fun of me. then it started running and i left.

i had a weird barro corr, i just turned it off

Sucks Adrian, but lucky you that it cleared right up quickly! I have had similar issues over the years, but nothing recently.

Everytime I hit BURN it also stuttersssss, but I've found that if I'm cruising at light throttle equal speed you can't feel the BURN, only if you're accelerating. Never have I had a problem loading an MSQ while driving, or changing any settings while driving. The only time that hitting BURN caused a problem, and Adrian should remember this, was in '04 on a drive up to Mount Baker with the Calgary guys. Almost to the top, I was tuning, hit BURN, biggest freaking backfire ever and it echo'ed off the mountains, killed the car so I pulled over. Matt Dupuis was behind me so he pulls over and comes running up "WHAT'S WRONG!?!?". I just laughed.

Adrian when are we going t00ning? Saturday mebbe? I want to ride in the 16 valves of glory again.

I used to burn to ecu all the time when I'd be cruising around.
I'd get just a light badump sort of a stutter, really just a single stutt I guess and it would be fine.
I think my MS box is magic though.
It started up and idled perfectly on the first try.

[MobBarley]

you arent supposed to burn tables with the engine running (at least not with msII).

[jpbturbo]

The things people don't tell me.
Good thing I don't have MSII then.

[adrianpike]

Good thing I don't have MS2! :-D

[The Aspirator]

Haha, ditto. I've never heard that for MS1, and it sure hasn't caused me any real problems. Man it'd SUCK to have to reset the ECU everytime I wanted to burn...

[qwkswede]

Yeah, news to me. I like to edit tables in ms log viewer, save the new msq, then reload the entire msq to megasquirt. Often when the engine is running. I often can't get a flash with the engine off. The voltage too low box pops up.

[The Aspirator]

Ken I just started tuning like that too, it is THE best method I've used so far, well when you're tuning with two people that is. Especially when you "trail live feedback" in MLV, so you can watch the datalog as it's taking place, then pause it, review, mod the map accordingly, and re-load it. Once I tie Boris' knock sense into MS to have it put a spike in the CLT signal then it'll make tuning ignition as easy as fuel!

Holy freakin' crap, that was funny. BOY do I remember that! Kirby and I had some old Metallica blastin' (& my stereo wasn't exactly weak), and all I heard was this KABOOOM! bouncing off the mountains. Stopped hard, jumped out, you two were laughing...

[MobBarley]

So why do you guys all use MS1 when MS2 is supposed to have much better resolution? I have only ever used MS2.

Do you do fuel only?

[Morten VJ]

I use ms1 because the ekstra code is more developed. More funktions.
http://www.msextra.com/manuals/MS_Extra_Manual_Index.htm

And when i first got into ms, ms2 wasn't there.
When the ekstra code for ms2 starts to get the same funktions as ms1 ekstra.
I might upgrade.
But i'm currently happy running ms1, for the 4 year.

100% ditto of what Morten said. I MS'ed 3 years ago, MS-extra wasn't even out yet. MS1 is so reliable and the extra features make it way worth keeping it for me. We all run fuel+spark through it, the resolution thing isn't really an issue. Plus some of the extra versions for MS1 have a high resolution code, which is supposed to rock.
