megasquirt
 
has anyone on here used the megasquirt fuel controller?from what ive heard it is cheap and very easy to use.a member of probetalk got all the parts needed for one for 126$.total fuel management for 126$ doesnt sound bad to me.let me know what you guys think.

Re:megasquirt
 
i posted something about this a long time ago. i didnt get any positive replies. but it sounds like a pretty good system if you're trying to be cheap.

Re:megasquirt
 
i dont see anything cheap about complete fuel management for a price like that.and it does work.

Megasquirt?! Hmm .... sounds like me after a long night of drinking Miller High Life. :) - Matt

works great, I've ran one on my toyota for a few thousand KM's, it was easy to tune, took me about a day to assemble and about 2 days to scrounge up JY sensors and install. Tuneability sure is nice.

With some Ford ignition parts you can have fully distributorless timing control as well.

Yeah Megasquirt is bang for the buck...good resolution.
Get a 3 bar map sensor with it on board. It's standalone withoute ignition control.
It's cheaper than a S-AFC and it has more features and better tuning capabilties

Re:megasquirt
 
it can also be used with the ford edis for total engine control now.woot.

Re:megasquirt
 
it may be inexpensive but it's certainly not just a 'make do' solution. It's as good as alot of the aftermarket systems, it's just no frills packaging. It is developed out of passion for the sport/hobby, not out greed (like Gre(e)dy or HK$ for example.

Fuel control upto 15,000 rpm
hi or low impedance injectors
22.5 PSI map sensor built in (2.5 Bar)
cold start enrichment control
tuneable accel enrichment for max throttle response
closed loop control
wideband O2 support (as well as narrow band)
fast idle control

..and with additional firmware and some JY parts;
2 additional programmable outputs for VTEC, fan, water injection, etc. whatever you want, can be triggered by temperature, boost, rpm ..you choose.
Timing control

timing and fuel are programmed on 8x8 maps

their are probably a few hundred cars driving around with MS these days, with 10's of thousands of miles, if not hundreds of thousands. Definitely worth a look at if you don't own something that can use something like TurboEdit etc.

In my case the best thing about the megasquirt is that there are no hard limits, it can do whatever the hell I want it to do because I'm pretty good with assembly programming.
It's also bang for the buck, a lot cheaper and lot better than piggy back units, as it has full 3d mapping and there's no hard fuel cut or whatever in it.
I'm going to convert mine to a modified version of MegaSquirt'N'Spark (megasquirt with spark control for ignition with a distributor) to drive a coil-on-plug system using GSXR coils.

hey neil85ae86 would you bild one for me? and if so how much would it cost me?

yeah me too its time fer you to make money ahah ;D 8) ??? :P

Re:megasquirt
 
sorry guys, I don't need money :) ....just time!

If you post on the yahoo group http://autos.groups.yahoo.com/group/megasquirt/ I know a few guys are selling them pre-assembled. I really don't recommend buying one pre-assembled. By building it you learn your ECU inside and out, and are much better at maintaining/troubleshooting, and depending on your application you might have to make some simple mods, that are only simple if you built the original unit.

I hadn't done any soldering in 15 years and I went out and spent $20 on some cheapo gear and a multimeter, and built it in about a day. A good assembler can build it in a couple hours. It felt awesome to hear the car start on it's first crank, running from an ECU I built myself :)

Re:megasquirt
 
does the megasquirt completely replace the ecu or does it use the stock ecu maps?

baldur 12-30-2003 07:01 AM

Re:megasquirt
 
It's a stand-alone unit, so it's a replacement. The default code doesn't do ignition though but there are a couple of projects that do fuel and ignition with the Megasquirt hardware.

Re:megasquirt
 
cool, so has anyone on here built one? what parts are needed to do ignition? I looked at the site a while ago and I still have alot to learn before I attempt this.

baldur 12-31-2003 07:26 AM

Re:megasquirt
 
To do ignition with a distributor you need a trigger wheel, pickup and an MSD box or a Bosch ignition module.
If you want direct ignition (wasted spark) you currently need a ford EDIS module, 36-1 missing tooth trigger wheel, pickup and coilpack.
