megasquirt

[StealthyWeasel]

I think clutch is the only one I know of that uses megasquirt. Whats the learning curve on this type of thing? Its open source like linux, so I like it. Im looking for a tuning alternative to sct (either megasquirt or twEEcer).. but basically all im wondering is am I gonna be able to install the thing and be able to tune my car decently in less than a month?

[20COUG00]

System us actually pretty sweet. Alot of probe guys use it. You might want to check over on probetalk for info. They also sells all the time there.

Seriously though, I have checked out MegaSquirt and it looks like a nice way to go.

:disgust:

haha

Don't you have to wire the program to the injectors though?

[Vyk]

Not sure how much it will help, but there are a lot of TurboFord guys who run MS. You might want to stop by the TurboFord boards (http://www.turboford.net/cgi-bin/ultimatebb.cgi) and at least read what's there. (If you ask questions, you might take some flak for having too many cylinders and driving from the wrong end, though. ;) )

Turbomustangs section of tuning has a great amount of info on it, i think there isn't a better way to tune than megasquirt but as previously said, if something goes wrong, you are to blame. I recommend building the system as you will gain alot of understanding of the system that way. You can buy the system assembled these days and with the tuning section of Turbomustangs.com/smf and now theturboforums.com you can get it running fairly quickly. P.S. I can do your sway bars now

The Megasquirt is decent for platforms that DON'T have any other fuel tuning options. That is not our platform!

With the Xcal PSP or the TwEECer available for our platform you can have complete tunability while retaining full "properly working" diagnostics (OBD-II), drivability, and returnability. There is no downside unlike hardwiring in a very basic stand alone fuel add-on setup.

The megasquirt only adds "control" for more fuel. That is as simple as larger injectors and a proper tune for our platform. Also the megasquirt only adds basic fuel control. It is at best equal to static speed density tables. Outdated and inflexible when compared to our MAF setup's capabilities!

[Clutch]

Mustangs have alot of tuning options, tweecer and ect. Tons of people run it, have great results, and tune at will

[Clutch]

They now have options for some computers to have a plug in option, no cutting anything. Not for the cougar though, but here is a nice pic to think on http://i157.photobucket.com/albums/t60/Cougar1911/index.png Man thats small, i'll try to resize, eh i suck at pictures

Last time I checked you can control everything a stand alone fuel management system can control including timing. I use the Megasquirt and it runs fine, But I work on specialty cars that require alot of custom work. I haven't lost my OBDII functions. Try reading the megasquirt site for tuning tips.

[FastCougar]

You know, I could have sworn it said MAF when I first read that site a few years back ... instead, it says MAP. So, I can sorta see the Greg's point since MAF is superior to MAP.

Must admit I am a little confused why you would want a system like megasquirt, when you have the ability to "tune your own" via the xcal psp and tweecer. Bit confused on your thinking here Stealthy??? Put the money into a a/f meter so you can tune to your hearts content with the xcal psp or tweecer.:confused:

http://www.msefi.com/ for good questions. If you can read this, it's one of my favorite uses of megasquirt http://www.theturboforums.com/smf/index.php?topic=62795.0

[20COUG00]

the cool part that i like about if is that you can remove you maf sensor (with proper tuning.) My friend has it, he can adjust everything.

Ok, I'll bite. Explain to me why removing the MAF is a good idea... I'm all ears on this one. Just be prepared for far more knowledgable people to rebuke every single point you can make as to why this is a "good idea".

[J-Man]

Exactly, how would the computer know how much airflow is entering the system? All based on just removing since you mentioned nothing about switching it to a MAP based system.

[Vyk]

J-Man: Megasquirt can be run as MAF, but was originally designed as MAP (and is probably still most commonly used that way).

I know that, my response was geared towards 20COUG00 who said you could remove the MAF completely.

[Vyk]

Well, you can...

[J-Man]

Without converting to a MAP system?

[Vyk]

I think the "it" (well, he said "if," but I assume that was a typo) he was referring to was Megasquirt, which means that you're converting to a MAP system.

I still don't understand why converting to map is so good?? from what I have read both here and in other places the maf is superior.

I work on all kinds of cars Maf or Map doesn't not really matter for tuning. But you want a Map if your doing turbo.

[Vyk]

The advantage of MAP are:
Fewer (and less expensive) sensors
No MAF (or even worse, VAM *shudders*) in the airflow (which, with the availability of large MAFs, is much less of an issue than it used to be)
There is more tuning experience out there for MAP than MAF (for years, all aftermarket systems were MAP)

And, no, I'm not trying to start a debate about SD vs MAF, I'm just saying that those are possible reasons. Especially when you're talking about switching from EEC-V (or EEC-IV for that matter), I think the main reason is "because I can, and I'll have done it myself" rather than a real quantitative benefit. It's also true that if you have experience with Megasquirt on one car, you have more reason to use it on another, rather than learning what may be totally different programming than you're used to.

...and, I'd argue with the turbos-need-MAP statement, but this isn't really the place for it. In any event, one of the best ways to start an argument at TurboFord is to say "MAF sucks, use MAP!" :) I think the number one rule for engine control is to use what you want to while trying to keep a real perspective of its strengths and weaknesses.

Thanks for that guys, it confirms why a chap in a dyno shop said that if I wanted to tune my car I would be better off converting to a MAP, it seems he has strengths their and experience hence his comment.

Will keep in mind what you have said their Vyk, they each have strengths and weaknesses. Not just in the operation side, but also on the tuning side.

[Clutch]

VOILA You can run a MAF on MSII and MicroSquirt http://www.microsquirt.info/mafmap.htm

No you don't.

Well the debate is on I guess. The MAF is system is enhanced in many ways and is VERY good for a turbo or almost any other kind of car. The best way to use it is a draw-through system because the turbo smooths all airflow if it is between the MAF and the intake, making reversion from valve opening events a moot point with it. It can be blow through but that isn't always 100% going to work without some tricks in the tuning.
In heavilymodified N/A veh. with radical cams it could cause issues due to reversion but there are parameters that are easily adjustible.
The main benefit is that you are using mass of air as the measurement and therefore fuel is added accordingly whereas with map there mass of the air is interpolated from pressure, temp, throttle position to name a few. The programmer can make or break the Map system.

[TrackCat]

No you don't.

I tune using both I prefer Map period. I'm going to go into anything with of explaining my theory or the reason I do.

Porsche, Audi, VW, And most cars us Map for tuuning there turbos

[warmonger]

Not anymore they don't. Do a check, most of the euro imports are using the Bosche injection system and all the latest bosche systems are MAF and have been for a few years.
My Volvo is a couple years old now, a 2005 and it uses bosche ME9.0 and it is a MAF system.

[GrandMasterKhan]

MAP is oldskool yo!

[Vyk]

MAP isn't old-school. VAMs are old-school. :tongue:

And updraft carbs are primordial-school. :biggrin:

Bosche is the fuel injection systems they've been using since the 70's.
so your point is??

[TrackCat]

Warmonger did you go to Fuel injection school?? if so where?

[cpapashley]

I thought Bosche is simply a brand name, Just like delphi etc. I thought warmongers point was that the recent bosche systems are all MAF.

[Clutch]

Anybody read where i said it now works with MAF?

[Vyk]

Anybody read where i said it now works with MAF?
No, I missed that. I read where I said it now works with MAF, though. ;) Anyway, I think this thread has basically degraded beyond the point of usefulness...

[Clutch]

Yeah, it may be dead.

[warmonger]

Bosche is the fuel injection systems they've been using since the 70's.

Yeah, but read where I wrote the ME9.0 system. That's the point and it is a MAF system and so was the system before that.
No biggie though.
