Mega Squirt
-
I have a Megasquirt in my posession. It's going on my Probe. I bought it assembled, so as long as I can trust that it was assembled correctly, that will save me a lot of time. These units are very customizable. Due to the open source design and a lot of extremely intelligent and talented people, new features are constantly under development. It's really exciting stuff. Also, the price can't be beaten.

I am now a firm believer that free and cheap EMS' fucking suck!

The megasquirt is mostly used by people with cars that have no viable piggy backs, or those who want a cheap standalone ECU. I was thinking about getting one for the yota, maybe I will next summer if I still have the thing.. Personally, I wouldn't put it on a DSM as I think the boost is somewhat limited to around 20psi if I remember? Maybe you can use a different map, but I am not sure. Have to read up for some details Al. I guess it couldn't hurt, you can get fully assembled MS and sparks for like $300.Nate you can get a 3 bar map sensor!!

No it still works, it is just lacking in features that I really really really need right now.

I built the computer early last summer and everything tested out just fine. I will be running fuel only control right away until I get all of the bugs worked out, then I will add the spark output option and take over my timing as well. The entire Megasquirt community has been growing a lot in the last year which gets more people involved in finding new ways of using the existing board for more options. I haven't been in the Megasquirt loop (I know what you're thinking) for quite a while again, but there were plans for ULTRA Megasquirt which was going to be a extremely powerful, reliable computer. It would use a new processor and almost all of the components would be surface mount instead of the thru hole components. This also makes it very hard (pretty much impossible) to hand build. ULTRA Megasquirt would have everything built right in: fuel, spark, wideband input, stepper IAC control, etc.
I can understand spending the money an AEM, MOTEC, Hondata, or comparable standalone computer if they make a kit for the specific application (Civic, Integra, DSM, Supra, RX7, etc.). For those of us who don't have a plug and play EMS available, it really makes sense to Megasquirt because you will have to build your own wiring harness, add sensors, and make other modifications either way. The tuning GUI isn't quite as cool as some of the mainstream EMS's, but the functionality is still all there. Follow the link that Kevin posted and you will have more information than you might want. Also check out http://www.msefi.com/ for more info on developments in hardware, software, different vehicle installs, etc.

AEM Makes an ECU w/ a harness that can be terminated as well.

Most of the people that decide to use a Megasquirt are cheap, like me. I'm sure the costs are much lower at a dealer, but according to AEM's website I will have less into my entire EMS than the price that they want for a harness. To each their own. I know that I will know more about my car and engine management systems in general when I am done with this install; something I find very rewarding. It is definitely not for the faint of heart such as someone thinking it will be a weekend install and one day dyno tune.

My take on it, is its not needed on a 1G DSM. All you need on a 1G DSM is to eliminate the MAS and your well on your way to 600hp capable. The ease of using a VPC/S-AFC combo is just hard to pass by. Install it and have it running flawlessly the same day. The stock DSM ECU does a pretty good job w/ timing aQ it sits. Only gain w/ the Megasquirt is the datalogging capabilities but then you gotta invest in a lap top as well and all y-ur gonna really log is knock counts anyways and on race gas you shouldn't really ever see any k ock anyways. If i were to do a other DSM for a basic 500-600hp setup i'd go right back to the VPC/S-AFC combo, tune on a wideband and toss out the knock sensor.
But to each there one, do hat you want, im just saying what i'd do for the setup/power your looking to make. If your looking to make 600+ then i'd go right to an AEM otherwise i wouldn't even bother w/ more than VPC/AC.

how about for other applications, such as non DSM?
