Who runs a MegaSquirt?

[Edub1]

How difficult was it to tune? Where can I get a base tune for 460cc injectors?

[pr240sx]

Waiting to hear some opinions on this

Right now I am debating betwee MegaSquirt and Bikirom........still researching

[480sx]

Well me and Sil80drifter have Ms, but i think were both still in the building phase.

I should be finished with my project in a few weeks, ill let you know how it goes.

The install itself is mad easy, if you can read a wiring diagram your good to go.

[sil80drifter]

Yup.I should be done in a month or two, I just have a lot of work related stuff to get done, so I am pretty much limited to weekends and even then, there are other things besides the 240 I do. Plus it's been raining cars and dogs in the northeast which really killed my 240 wrenching mojo.

I can tell you that tuning the 460cc with SAFC was relatively easy. As soon as one of us has an MS map (I have MS II btw so it'l be different than MS I), we'll make sure to post them.

Good deal. The newer model is usually the way to go. Here are VE values for the KA that some guy posted up some where. May as well start with these.

N/A - - 10psiRPM - VE - l b/min - lb/min2k - - 78% - 4.5 - - 7.52.5k - 82% - 6 - - -- 103k - - 82% - 7 - - - - 123.5k - 88% - 9 - - - - 154k - - 95% - 11 - - - 18.54.5k - 96% - 12.5 - - 215k - - 93% - 13.5 - - 235.5k - 87% - 14 - - - 246k - - 78% - 13.5 - - 236.5k - 66% - 12.5 - - 217k - - 54% - 11 - - - 18.5

Had mine for over a year. Tuning is simple its pretty straight forward. If you hook up the wideband you can have Megasquirt do a Autotune to atleast get you going.

I never tuned in my life and MS was my first.

[Edub1]

I will be going this route eventually - I might wate for the UltraMegaSquirt. The ability to hook up to a WBO2 is awsome.

[480sx]

You can hook up a WB02 to MS2 as well man.

In fact, you make an AFR table, plug in your injector size and estimated HP/torque and it makes a VE plot for you. I was amazed at how easy getting a base tune for MS is with WB. Also MS supports all different types of WB's, be it aem, Zeitronix(which is what i have), or the LM1. A few other are supported, but i cant remember the names atm. (MS just keeps sounding better and better to you right? I know the feeling ^^)

With as cheap as MS2 is right now, i would go with something that other people have. Just to have a group of people on this forum to talk MS with. If you get the new one thats coming out, we cant collaborate as much. Thats just IMO however, the new MS does look shweet.

[Edub1]

I am so on board with the MSII. The WBO2 needs to have a controller to wire to it - the ultra will have one built in; so what. I'll have to sell my NGK and get the LC1, but yah how can you beat that.

My friend might be able to get my car dyno tuned for me at the tech university where he teaches. Class demo type deal.

But anyway, a full stand alone speed density system that is 100% open source for only a few hundred bucks. That so beats the hell out of half blind ROM tuning or BS piggieback systems.

I was leary at first but I'm starting to see that it's a no brainer.

The LC1 comes with its own Controller, Its that rectangle thing the O2 sensor plugs into. As for Ultra Megasquirt thats like 4 years away, plus SMC3.0 should be out in a year or 2. Which is like Ultra Megasquirt but a reality. SMC3.0 is gonna be MSII V3.0 with the Router Board, and GPIO board in 1 surface mounted PCB. Supposedly will also have a Dual Core processor.

As for Wideband Controller, you can build a circuit for it on the Proto area. http://www.megamanual.com/PWC/

This is the State of The Union for Megasquirt.http://msefi.com/viewtopic.php?t=24765

It is one of the best options out their, sad though ignorant people put it down because its not plug n play and has 12x12 maps. Oh well it takes them getting beat to show respect. With all the stuff coming out some Standalone options pretty become obsolete like SDS.

[Edub1]

Right, the LC1 wires directly to the MSII and is plug & play. Is there any benefit to messing with that board? I think sensor & LC1 is like $150.

Is there a problem with 12X12 tables? Can these be expanded? My friend was a chief engineer in power train management for Lear Corp. He wrote the code for the Ford distributorless ignition and authored 2 multiple spark patents. I'm sure he could expand them if it's possible and necessary.

[Chezedik]

Still, I would like something with more resolution. Does anyone know if Ultra will give something like 16x16?

I am looking hard at this for after I move. I have had so many problems as of late that could have easily been solved with standalone.

[Edub1]

Even if it is only 12X12 - so what? It's light years better than anything else out there save for the top dollar units.

Also, the MSII plus a wide band lets you enter your desired AF ratios in a map and it will self tune - all you need to do is fine tune it.

As soon as my boat is in the water and I have some free time I'm getting one. This ROM tuning crap is for the birds.

[Edub1]

My MSII is on the way. Anybody work out a good tune for an E motor yet?

[sil80drifter]

Give me til beginnign of November. I'm still trying to get the other stuff sorted out but in september i'll start putting it in and tuning... or getting it started, then tuning... =] ain't it funny that when u wanna have some time to do it, u have none, but when u don't have anything to do, it seems u have so much time on ur hands..

[neverlift]

damn edub you could have got a cheap *** laptop and a consult and no more blind tuning.... lmk how the ms goes though, it was my first consideration when I wanted to start.... price/function ftw

[Edub1]

Neverlift, I have tried every possible combination of ROM tuning and have never gotten anything near a good tune. Plus, I couldn't get ahold of a cable.

Anyway, when I look at the functionality of the MS vs the current state of ROM tuning for the E motor - forget it.

[neverlift]

I know yo have TRIED. But without consult its blind IMHO, you need to know where the ecu is looking to tune it, it took me close to six months on my e motor before I was even close, only cause NO CONSULT/DATASCAN, if I had that I'd have finished in 3 hours work.

just my veiw on it, if you wanna go ms do so, I want to know how it goes like I have said I was very close to getting one myself, but i had decent success. At least for my needs/setup, I mean high 30mpg while mix of city highway drifting was great IMHO.... go for it man

[Edub1]

I coldn't get my hands on a decent cable. Plus I'm not sure we are talking about the same thing when we speak of a "good" tune.

Like I said, I tied every combination immaginable and made outrageous changes to my fuel maps with absolutely no change. As long as the final TP column is not too large and the ECU reaches it the ECU will stay in that column and maintain that AFR no matter how much air comes in. By setting the TP small you automatically know that at WOT that's where your info is. You shouldn't need to see this with consult.

Plus, those TP scales are fairly large steps and it is mathmatically doubtful that you could even be more than a column or two off at the most given the marging of error. This shouldn't make the car stammer and backfire and fail to even rev and it shouldn't make the car run in the 9s under boost. Where on the fuel map is a cell that calls for a 9:1 AFR? I would have to have been too far left which would be lean or pegged to the far right row which still can't be 9:1.

The best tune I ever got I found was due to a boost leak. IDK, perhaps the Z32 MAF is tough to work with.

Anyway, there is no going back now so it doesn't matter. Can't wait to sell my BTM & Z32 MAF to get most of my money back. Plus that crappy recirculated BOV is going bye bye in favor of an open atmosphere SSQ.

[LEMHEAD16]

For those of you running it are you controlling Fuel and spark or just fuel.

[neverlift]

you can use dual control yes....

dub, lmk how it goes, again though, the tune I made took a while but was great. Even the stupid hybrid ****(de on sohc ecu /maf) I'm doing only took 4days of kinda steady working on it to get a (hate to say this in a sentence..) drift ready tune, I mean day four it was so close, slight fuel adding was needed(probably not but I wanted safety)..... just saying kick eccs its decent for what you put into it(not all cases ,clearly you had issues), I know ms will go smooth long as all other parts are good. Have fun with it man, have to catch you on here form now on...

[JAY-BIRD]

Im ms ing my 240 right now... from what i here its always a learning process.. and if you go with the wideband it will help you out alot... when im done with mine ill let you know man...
