Ordered MSPnP!
 

So I finally ordered a megasquirt and for some reason im really excited haha. I guess its that first big step toward boost :). Is it normal to be this excited about it? lol

More exciting to crank the car up for the first time. Course it's more if you built the MS. Wait till you go boosting. :)

Congrats; a fine purchase.

trying to run the map hose thru the firewall. got the rigged grommet and the hose Tee'd off, but theres a bunch of padding blocking the hole. Is it safe to drill/cut into that foam without hitting wires? Or does someone have a better spot to run the map sensor hose?

The grommet that all the wiring goes through on the passenger side has a little nipple on it. Cut that nipple off. Instant vacuum line hole.

doin this by myself is dumb, going to wait on someone else to feed the hose threw.

I did it.:bigtu: Really not that hard.

Take your glovebox out. Makes it 1000x easier.

yeah i got it finally lol. the right side of the plastic/insulation wouldn't fold over, so running my hand up in there was a bitch.

now im having problems with the com port lol. com3 is the female VGA port, ive tried com1,2,and 4 none of them have worked. read the sticky about comports, guna download the up to date safeware and firmware tomorrow and should have it running.

once you install a serial/usb converter, it should appear as a certain com designation in device manager. If you need any help getting your ms set up, I'd be glad to give you a hand.

says its com1 in device manager and i've tried that :(. i appreciate the offer but your out in nashville, so no worries.

You're using DIYAutotune's USB-Serial adapter, right?

got them communicating finally. did a software update and it worked fine :). loaded the base map for 96-97, didnt start but im 97% sure my battery is just dead, charging it then trying again.


but for reference, im running a 2000 head, 2000 intake manifold, simple ddm works intake, stock header, 2.5" test pipe and 2.5" exhaust, stock injectors. the basemap should work fine...... right?

do yourself a favor and cut a big-ass portal down by the trans tunnel and run every wire through it (with a grommet). Thank me later.

I had issues with killing my battery while I was setting mine up too.

But yes, the basemap should be fine, but a wideband should be your next investment.

whoops, need to update my location. I go to UTK, so I'm in knoxville most of the time :)

Edit: gonna have to agree with hustler. I drilled a new hole lower in my firewall close to the transmission tunnel because I had to run new MAP, IAT, and TPS lines. It makes things a ton easier to put it in a spot thats easily accessible while you're messing with your wiring.

haha, yeah ill have to do that soon.

got it running, waiting on my friend with the timing gun to double check timing, its reading 4.3 afr at idle but when i give it gas itll go up to 13.5-14.3 is this a major concern?

I'm sure you mean 14.3 because you went into the MS configurator and set it up for whatever wideband you're running, after you configured the output to report 0-5:10-20...which can't read any leaner than 10.0:1. ;)

oh damn, ill have to have look over my install of MS sometime then.

got it installed, base timing done. it runs SOOO much better now, ill have to record a log and post it up so you guys could see if anything dumb is happening.

what other simple things should i adjust with it? i calibrated the tps.... it idles kinda high, 1200rpm and thats after i turned the idle-screw all the way over.

1200rpm huh? thats a little high. how many kPa are you pulling at idle?

Gettin 52 kpa at idle(1200rpm). ill post up a log once i get home tonight. seems like the system is draining my battery, had to jump my car off this mornin altho it was cold as balls.

btw, im retarded, i forgot to ignore afr because i dont have a wideband yet. but go ahead and bash the nub, im still learning!

as far as the cable, i use what came with it, the male vga-like cable, not a usb. its working fine tho, my best purchase yet.

My car is hardly one to use as a reference, as I just got it running a couple days ago, but it sounds like you've got a vacuum leak somewhere. Mine runs something around 25-30kpa at idle. Hopefully someone else can chime in with their numbers to give a better reference.

50ish kpa at idle is not right, as well as the obviously incorrect 1200rpm.

Have you played with your idle screw or idle settings in megatune? What are your settings right now?

mine idles at around 880 rpm, 35-36kpa.

Damn, maybe I've got a leak too :(

mine idles at 9500rpm at 25psi, son.

haven't had a chance to play with the idle settings in MS yet. I've got the idle screw turned all the way down(to the right). it was idling at 1600ish rpm before i got to the idle screw. It doesn't lope like a rotary anymore but there again, it doesnt idle at 800-900 like it did before.

I wouldn't doubt a vacuum leak somewhere, lots of possiblities after the head swap. I'll check with the idle settings in Megatune next time i get a chance. And give my lines another good look over. Actually couldn't i get some soapy water to put on the vacuum lines to check for leaks or does that not work at all for this situation? lol

I'm doubting a vacuum leak only because once I had one and it didn't idle high, it just wanted to die or hunt for idle unless I gave it gas. Not to say it isn't possible that a vacuum leak is causing your problems...

My memory is terrible, but dont you have to turn the idle screw to the left to lower the idle? I could be very wrong but I seem to remember having to turn it all the way to the left after my engine build to get it to idle right.

Mspnp ftw
 

Congrats Flier, I'm in Chattanooga and just got mine installed about three weeks ago. Still very unfamiliar with some things, have to finish the install on my LC-1 also. Can't wait for it to warm up so I can get my car dialed in. That or I need some heat in my garage.

This may or may not help you, and by no means am I an expert...I've richened up the intersections for 500, 900, and 1800rpm and 20, 26, and 34kpa to 49-50% and got both my idle and kpa down a bit. I'm idling at about 900-1000 right now with tuning of the idle screw and at around 26-28 kpa. You could def use a small amount of carb cleaner to find vac leaks if you think you have them.

Good Luck, I think a bunch of us MS newbs from TN should get together for the MS Meet in April down at DIY. :)

thx! yeah we should caravan down to the DIY meet :)

well, im nub, how does one upload a full log for megalogviewer so some of you guys could take a look. or is that even possible?

ive got pics though!

so is it f'd? btw i was spinning a whole lot, cold and old tires lol

hmm. its hard to say from that log, at least it doesn't tell me anything. I could come look at it sometime this week though if you want to have a gay black NA miata meet-up, haha.

shitsfixed, vaccum lines were crossed up, for future reference.

in case anyone was wondering, cjernigan is still the jesus of megasquirt.

mixed up/popped off, funny shit. car is running a lot better, just wondering how it would run with VICS working properly haha

and cjernigan definately knows a couple of things about MS...... just a couple. 20 sec troubleshoot and it works, hah.

bad news, sounds like its knocking. either that or HLAs, only makes the sound at certain rpms, does it at idle, 2800-3000, and 4800-5600 rpm, might just be running to lean with the cold air. guna tinker with the map later on tonight.

the oil gauge on the dash that i never pay attention to because it never moves is now moving like crazy. itll go to low at idle or no throttle, then go to where it normally is under load. might have a missing vaccuum hose?

ooh, thats no good. that's a dummy gauge, and it only sinks when your oil pressure is below a really low amount.

I know the tune wouldn't cause knocking; I made sure it was running rich enough all the time. I didn't check your spark map very thoroughly though, I figured it was the stock pnp spark map. look at some other maps if you can find them on here and compare them, or post up a screenshot of yours.

Either way, none of that could really be related to your oil pressure gauge hopping around. It's hopefully a vaccuum problem. Worst case it's an oil pump problem. Did you replace your oil pump when you did the head swap?

Now, for your vaccuum problem, I feel like I had the hoses set right, but since I don't have one of those pesky intake manifold things, I can't be totally sure. Would anyone with a 99-00 car/head be kind enough to chime in as to where their megasquirt MAP lines plug in?

shits fine, im retarded and dont check my oil enough, always looking at my radiator.... go figure.

idling like a dream and runs like its suppose to. now wheres that turbo!
