Anyone using MegaSquirt?

update time! sorry yall, school has been more than nuts, and with exams coming up, there's not really much hope of an update very soon either. here's what's going on. EDIS is STILL not in. I left it at home so I wouldn't be tempted to work on the car with exams looming up ahead. The car did make 240whp on a dynojet though, as you can see. I don't have a scanner, so i just took a digi pic of the graph. Car is running great, I'm working out my cranking numbers to get the car to start up first try in cold weather. It always starts, it just sometimes takes a bit longer.

I'm running Megasquirt in MAP mode because I'm running i high-boost setup. MAF is indeed much more accurate and user-friendly for NA and low boost. There is probably a better way to do MAF tuning than with MS though. It's really made for high pressure. not to say it's not meant for it, there's probably something better out. Hard to beat the price of MS though!

Mazdaspeed626, you lucky piece of crap! ignition is going to be so rediculously easy on that thing! wow. I'm jealous. I can provide you with configuration files if you would like them. They're probably not incredibly useful unless you have an injector flowrate around 440cc/min though. Lemme konw if i can help out in any way with your install!

QCMSP, that is confirmed. without heavy modification, MS isn't set up to handle multiple-coil drivers. With MS-II, there is some work being done to program for multiple coil drivers, to accomidate virtually any system. As of yet, though, it's not possible without an additional control module (like the ford EDIS system or the HEI 7-pin system).

Innu_Qc, yes, I pretty much just tapped into most sensors and such. I disconnected the injectors from the stock computer at the injector, and connected them directly to MS. other than that, it was just finding a good power supply, using tap-splices on coolant and air temp sensors, and going from there. Good luck.

More updates soon. Sorry, but you'll probably never see a time slip for this car. I start dropping the clutch and the diff will pop. guaranteed(i've already done it once). I'll post some times from VIR though! And some autocross results...

Hasta luego,
-Mateo
 
Thanks for reply !!! But you have already answer me on the MS-forum !! Yes it's me :)

I 'll keep the MS in mind for next summer .. I probably ask you few more question about it soon !!

Thanks again
See ya

haha, ya, its nice. But it's not gonna be clean cut and dry because i'm OBD-II and the EDIS module is integrated into the ECMSo I might have to get a module(which i'm not to worried about cuz they're only like 35 bucks) to control spark if I cant figure out how theyve done it on this page below. For those that want to run multiple coils through megasquirt, heres the link: http://megasquirt.sourceforge.net/extra/setup-wheel.html
But, its pretty complicated and might require a few additional parts? Im not sure, but read through it and see if you can interpret it, its pretty interesting.

I will be boosting here within the next month or so, but i plan on starting out with low boost(5-7psi) and then working up slowly as my hunger for more power grows....hahaha. So for now, i'm gonna be using my stock maf(maf before turbo) with a 12:1 FMU before i get the megasquirt in(money is killing me right now....). But once its in, i plan to convert over to MAP, cuz yes, MAF IS better for NA, but a tad bit more difficult when boosting....at least when it comes to integrating it into the megasquirt.

nope, im not running 440 cc/min injectors...wish i had the money for that...haha. where did you get your injectors, i might spring for them when i start upping the boost a little more. As for an MS tune, I would love to go over your Megatune setup you're running, just to learn a little more about what you did and how you figured it out. PM me or something.

P.S. If you need help setting up EDIS, lemme know, Id be happy to help. Oh, and if you need a 36-1 toothed pulley, i have an extra one that came off my car when i replaced it a while back....don't ask why....but i believe its in pretty good shape, i'll look at it tonight and make sure.

I REALLY need to learn about fuel management, that s*** looks confusing as all hell to me...:D

What is it that's confusing? The Code behind what makes the systems work, or the actual tuning aspect? The code can be really confusing if you've not dealt with computer programming, but the tuning aspect is mostly basic equations and then trial and error. If you want to read the theory behind tuning, start with the basics of how modern engines work and then read the section on tuning on this page: http://www.megasquirt.info/ It explains basically EVERYTHING about tuning. The link is on the left hand column titled "tuning."
 
It's the tuning aspect and numbers that gets me. Thanks for pointing out the info, I can start out by reading that.

EDIT: Well, the whole damn thing actually(boom07)

The fuel part is simple. The ignition is what always confuses me. I still can't understand why the need for EDIS in most cases. All this HEI, CDI, coils, distributors...(confused)

Anyone know how fast an RPM the EDIS modules can handle? I'm thinking about a working on an NA project car(not a protege) using MS and EDIS that would possibly rev fairly high.
 
i think its like 9k or 10k max. EDIS is used cuz that's all the MS codemakers have come up with so far. If you can come up with some new code that we could use to run ignition straight off the MS, by all means, go for it....i know i'd use it!
 
hell yeah! I'll use that coil driver code!

Yeah, ignition is confusing! I'm going day-by-day figuring out how to tune as i go along. Having forged internals is nice, i have to screw up big to blow it up!

Steve Nackers at NSN is incredibly knowledgable with timing and tuning stuff; I might just use his ignition map, strait up. consider that credit, steve! haha...

Mazdaspeed626, gimme your email and I'll send you the .msq file for you to look over. be advised, the timing map is stock Megasquirt, unaltered. I think you'll have to get an EDIS module that will accept a SAW (spark angle word) signal to control advance, the PCM probably won't let you mess with it. My car already has the 36-1 wheel, but many thanks for the offer! Contact boost engineering (www.boostengineering.com) for the module. Are you on the MS boards? what's your sn if so? Thanks.

update: timing implemented, made 280whp at 16psi, click the link in my sig if you wanna see that. I have an updated timing map for those of you running 8:1 compression if you'd like it. It's not particularly aggressive, but it makes decent power.

no timing changes. I haven't had access to my dyno for quite a while, so I haven't been able to make changes safely. That turbo spool ultra-quick, whick I really like, cause on track I can get on-throttle, and be at full boost by mid-turn. Sometimes it's not really necessary, but it's nice to be able to do it.

Awesome!

Just got my MSnS II with EDIS. Ill work on the harness this weak and hopefully by Memorial Day Weekend Ill have the old 1.6T running. Any body got a base map theyd like to share so I can make some comaprssions, I greatly appreciate it. Especially interested if anybody got there OEM IAT idle air control valve setup and working.
Thanks
 
hey, I've got my maps still available, they're for a 2.0L turbo with 440cc injectors. If you adjust your req_fuel and enrichments you should be able to use it as a starting point. Just shoot me a PM with your email and I'll send you them. your IAC valve will actually run on the stock computer just fine as long as your ECU has a good RPM signal. That's the way I did it, and it worked fine. if you have any questions, just shoot me a PM!
