Here's how to get your hands on the fastest-growing EMS available for an FC. Complete tunability for half the cost!

Viola!

I have one word for ya.

megasquirt.

http://www.bgsoflex.com/megasquirt.html

yes, its only fuel(which is all most need), but the megajolt will be out soon to, and that does ignition.

 

I work in the I.T. field so I am allowed to say this.

You have to be a real computer dork to build your own ECU. I highly dought its cut and dry.

Theres also more crap you can mess up. Not to mention even less support for the product.

The megasquirt is a good idea, but its just not its time for me.

 

I am a real computer dork

you could also get someone else to build it for you.

 

Hah. I've tried to build a Stoaks FCD, and I'm a Real Nerd. I could have done it, but after the second hour, I figured it just wasn't worth it.

Plus, as much as people complain about the LT8's 0.06ms injector resolution, imagine what would happen when the figure out that the Megasquirt's is 0.1ms. Or that the Megasquirt doesn't support staged injection (last I checked). The list goes on. Besides, the LT8 is a fully blown EMS for $650, dude!

people have done it on rx-7's, so it will work. there is a hi res patch for it that allows a res of 0.05ms.

I, and a lot of other people on here, don't need a fully blown EMS, but want something better than an S-afc.
I think the megasquirt fits the bill.

EDIT: actually, hi res patch allows you tu go as fine as 1 microsecond increments. which I think would be 0.01ms

 

i want to join but the group buy but the mailing list is stupid! who can i e-mail to join the group buy?

Please let us know where to get more info on the Microtech than that link you gave. I'd like to see screen shots of the software, as well as a list of everything it can do and specifications.

Advanatages and disadvantages of the Microtech vs. E6K and E11

 

If you go onto the microtech section you can read all about stuff. A few of us have already demoed the software.

Of corse the e6k is a better unit, but being on a budget can work just about as well.

 

Questions:

*The unit has a rev limiter which cuts the primary bank of injectors(not suitable for 13b turbo's with staged injection)as well as a rev cut which cuts fuel out all together.
*

However at the top, there's talk of revving past 9000rpm. I presume that the rev limiter is a changeable value in the EMS?

On another note, what considerations have been made in regards to any elec OMPs?

 

2 types of rev limiting. One is not good for rotary, the other is fine.

After 9k rpms the curves remain the same. Reprograming can change the ecu to 10500 if you want.

I dought elec omps are supported. Im premixing anyways.

 

SaabGuy is right on the money.

S5+ OMPs aren't supported (just like every other EMS ), but a quick change to an S4 water pump housing, OMP, and throttle linkage will allow use of a mechanical OMP if you require it. I'm going premix, though.

If you're having trouble joining the email list, email me at bmatt@devils.eng.fsu.edu and I'll walk you through it.

what About STS???

 

Sweet! Thanks no7yet.

 

STS?

Megasquirt does support dual stage injection if you load the dual table code into it. There are a few people using it for water injection and secondary injectors for nitrous.
For 'computer dorks' like me it is nice to have source code that you can modify to open your 5-6th ports and you could support the OMP if you cared to waste your time with it <cough>premix<cough>.
Guess those looking for an out of the box device that does *most* of the things they want it to would not be interested in that though. As for support, how about direct (well as direct as a yahoo group can get) interaction with the developers? I've been watching the group for a month or so and most questions are answered in a few days at most, even stupid frequently asked questions that would get a SEARCH!!!! response here.

Please excuse my rantings, I am sure there are quite a few people here that care nothing for a device requiring that much effort to install/create, but I hate to see a great thing misrepresented.

 

Well, sure the Megasquirt is a great DIY tinker-toy. I work in the IT field and have done embedded device programming, so it's not that the Megasquirt is scary or anything, it's just that the Microtech is a complete system with established tuning and tech support available. I might even get the impoetus one day to put a megasquirt on a turbo 12A or something, but for $650, I'd much rather have a system that doesn't require tinkering.

I use SuSE over Debian at work for just the same reason.

The great advantage lies in that the megasquirt is living, while the commercial devices are mostly static.

For instance, a member of the megasquirt yahoo group is testing software to auto-generate corrections to the look-up table from collected data, something that I think is new to aftermarket engine management devices (though I don't see why it has not been done before).

Like you say, a definite tinker(ers)-toy.....

 

Autronics has a self-learning feature, If my memory is correct

 

we need knockoff haltechs & EMS for 1/5 of the price

 

can i get a wiring a harness for a 13-RE? im going to do this swap down the road. i dont know anything about this system though. but it sounds like a cheaper alternative to a haltec. A link to some more info would be good. i would go with the LTX8 for my conversion.

and whats with this?

"What will likely happen is that I'll have them all shipped to me from Australia, and then will ship them out individually via the USPS."

so we are going to have to go through australia?

 

The wiring harness is universal. You'll tell me which set of sensors you're using, and I'll relay that info on to the distributor. All the engines use the same set of sensor types (i.e. water temp, air temp, etc), so the LT8/LTX8 application is universal.

By the shipping thing, I mean that all the units will be shipped to me from Oz, and then will get sent out to their final destinations from there. It'll work out cheaper that way. I'm taking care of all the dirty work, tho.

Brandon

 

hmmm.. i hope everyone can be trusted. If the guy in austrila runs off with our money, theres not going to be much we can do over here.

 

The guy (Jon) works at a pretty well-established business in Australia. Complete with business licenses and local law enforcement bodies. The FBI also has an internet crime investigation division which (iirc) has the authority to investigate international fraud.

Unfortunately, it's a risk that's always inherent in such long-distance transactions. Believe me when I say I don't take the feduciary duty of handling up to USD$10,000 lightly.

B to tha' izzump.

If 15 people get in, the price drops by $65!
