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

I guess it couldn't hurt, you can get fully assembled MS and sparks for like $300.If I ever get my car finished it will be it will be running a Megasquirt. 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?

the whole megasquirt thing is an excellent way to keep your engine running. My friend with the 280Z and the megasquirt is getting ready to megasquirt an 83 280zx turbo, with the ignition control. that should be interesting to see.
On the "you get what you pay for" note..... the reason megasquirt is so cheap is because of the software. Its freeware. the system itself is capable of AT LEAST as much as SDS, for about 1/5th the price, and thats for the prebuilt unit. Also, they just released some PDA software that allows you to run the damn thing on that!
Megasquirt is, in my opinion, better than any piggyback. You can get one with a 3 bar map sensor, so hi boost situations arent a problem. You can also get 12x12 VE and ignition tables in a code download called "Megasquirt and Spark Extra" plus, megasquirt II is now out. And that has a freaking FAST processor.
I myself am waiting for Megasquirt Ultra. It will have 12 user definable outputs, so on my I6 motor, that means 6 injectors and 3 for ignition. Full sequential Fuel injection as welll as 3 wasted spark coil packs. Im sure I can find a use for the other 3 outputs as well.

When watching the 1011rwhp Parrish video something besides the insane amount of power sparked my attention.
Parrish video thread:
http://www.fargostreet.com/showthread.php?t=3981If you look closely at the video you can see that this truck is running Megasquirt engine mangagement. See the attached when shows a screenshot of the video.
Look at the A/F curve at 3:26 and you will see that it is very flat all the way across the rev range. Put in the hands of the right people, Megasquirt is a completely capable engine management system.

You can make a completlt flat A/F curve w/ any managment, even piggybacks and chips, so whats your point there?I simply wanted to show that this system is being used on applications that have made tremendous power. I'm pretty sure Parrish could afford to run any standalone EMS, but chose to run a Megasquirt for whatever reason and it has served his 1000+ HP needs.
