Megasquirt
 

Has anyone on here used, or know of anyone that has used megasquirt on a car?

I'm thinking of swapping my carbs for fuel injection but dont want the hassle of all of the wiring changes, could i use the megasquirt to save a lot of time?

Re:Megasquirt
 

what is it?

Re:Megasquirt
 

its an awesome DIY engine management system. I've always wanted to use it

:D I was going to say do a search on Google, but all that comes up is Porn sites... you'd never get the right answer :-X

LOL :)

Chris - ive been posting about this in the hybrid/tech forum, you replied a couple of times, i took into accont what you said about the dash harness and the engine harness and how you thought it would be a waste of time and i came up with this option, for $160 or so i can get the megasquirt, then all i gotta do is stick on the intake manifold and the injectors, with the few sensor that you get with it also a fuel pump and hey presto, i get all the benefits of a fully programable ECU, fuel injection and i dont even have to ---- about with either of the wiring harnesses (well maybe a little)

Although all this seems too good to be true for the price hence me asking for opinions, who thinks this wont work and why?

Re:Megasquirt
 

surfer, i know of at least one member running MS on his car...his name is Rabbitshit. he has it running his 78 Rabbit with ITB's. i will also be running it on my GTI but i dont know much of ---- about it...

THis part sounds the most promising and uplifting for those kinda scared of a standalone setup

What You Do NOT Need

Programming skills. The assembly language software is already written and loaded, and the tuning interface is through a straightforward Windows application. You can, of course, conceive, write and load you own code if you wish.
PROM burner to make tuning changes. A serial port connection allows adjustment of all the tuning parameters. Software updates are up-loadable through the serial connection as well.
Advanced electronic skills. If you can solder and follow directions, or are willing to learn, you should be able to successfully assemble MegaSquirt. You do not need to know what each and every component does, as there is a comprehensive assembly guide to walk you through the entire assembly and testing process.
Latest laptop computer. In fact, newer computer often do not have the serial port that is needed to communicate with MegaSquirt (instead they have USB ports). USB/Serial adapters can be used, but an older laptop is very cheap, and often a better solution. You may want a faster computer for processing data logs with MSTweak3000, but these can be done separately on a faster desktop machine.

Sorry I'm a little late on the thread.

I'm using it right now on my 4afe Celica, it kicks ass.

For 180 bucks, I bought Megasquirt and the Stimulator (which tests megasquirt). Glensgarage.com is a good place to source it all, they package everything and lable it, very convenient. I spent about 6-7 hours soldering everything, startging with the stimulator. It was my first time soldering a board before, so I wanted to be extra careful.

It's very simple to create a pigtail, you basically hook up injectors, tps, coolant temp, air temp, and a vaccum line from your intake manifold, right into the built in 2.5 bar map sensor.

I then bought a cheap 100 dollar laptop to tune with, and it functions perfectly. Very easy to tune, you just set your constants, and info about your engine, and it automatically maps ---- out for you using the Ideal Gas Law and constant we all learned about in highschool chemistry.

Overall, I believe for those that don't want to run Uberdata or something similar, or can't, it's definately a good start. If you have any questions, PM me of AOL IM me Snafubmx234. Peace

Re:Megasquirt
 

Oh, and PS.

I've never worked or tuned anything in my life, this was my first time I've ever hacked up my ecu harness, first time I've ever soldered, and everything functions perfectly. No reason to be scared at all.

Re:Megasquirt
 

I've been running MS for 2 years now on my 4age 1600cc Corolla, last spring I added a turbo and did the DLI programmable ignition mod. I really really like my MS, it was my first project into the realm of engine management, and I have no regrets, it can do everything I've ever wanted and more therefore I have no plans to switch back to OEM or try other aftermarket setups, plus it's very reliable.

Re:Megasquirt
 

they work great on toyota's and dodges that use batch fire efi systems.

honda's are sequential so putting an MS on there would be like 4 steps back. you'd be better of building a harness and wiring up obd0/1.

i was/still sorta am considering a ms for my dodge daytona but who knows...

Re:Megasquirt
 

you seriously don't think that sequential is 4x better than batch? It's been proven over and over again that all sequential is going to get you is a little more fuel economy and a little better emissions, but that's only with lot's and lot's of tuning with high end analyzers and lot's of expensive dyno time, so if your running a chipped ECU with typical DIY tuning, your sequential isn't doing squat for you over batch.

Re:Megasquirt
 

i didnt ------- say that

i just said using a batch efi system on a sequential engine is retarded. you spray fuel in the manifold and it has to WAIT to be sucked into the cylinder. thats just inefficient.

batch works great on engines designed for it; i wont argue with thtat. but putting batch efi on a sequential motor when so many better and cheaper options exist is like buying a Ferrari Enzo and pulling the motor and puttin in an SBC or some retarded ----. it works but is ------ dumb

Re:Megasquirt
 

Hey Neil-

I was thinking of hooking up megasquirt'n'spark. What made you go for the DLI mod rather than hooking it up using the dizzy. Do you konw much about how megaspark can hook up to our factory ignition? Thanks man,

Colin

Re:Megasquirt
 

WHen i was researching using MS on my friends crolla we found it was just easier to use a msd crank trigger

Re:Megasquirt
 

ok so im kinda confused i read that its like taking 4 steps back in a honda but is anyone running megasquirt on an obd-0 car? im very interested in this setup but it seems to be a non honda thing

Re:Megasquirt
 

Honda has so many good options for it now that MS isn't too practical. Its great for other cars where there are no standalone options

Re:Megasquirt
 

check this one...www.vems-group.org
based on the megasquirt, but it uses sequential injection and can control any ignition type..DIS, distributor.
And has a lot of features..for a 4 cilinder it will add up to about $500 but it's just like a standalone and features that you can add yourself if you want or not..integrated EGT,WBO2 etc etc

Re:Megasquirt
 

Why I got rid of my dizzy;

1) it was just waaay to congested - turbo plumbing/dizzy/brake booster/brake line junction/powersteering all located on the same side of the engine
2) the nearly 20 year old dizzy was worn, had the usual internal oil leaks, parts around here are getting scarce and new parts are expensive - ever priced ignition parts for a 90's escort vs. a first gen Denso EFI? Also, I expected to have all sorts of problems with the ignition components with a turbo stuck between them generating huge under hood temps
3) DLI, less moving parts, lower maintenance, good spark energy, EDIS is standalone and has a 10 degree fail safe mode, great for limp home
4) lot's of ppl have done the conversion, so lot's of guys to work with ( I wasn't the guinea pig :) )

I really spent alot of time building my harness, I added lot's of new grounds, the engine runs silky smooth with EDIS, and hit's 7500 RPM without hesitation, I couldn't be happier with it. Currently I've been running as much as 13 psi, with stock gapped 4agze plugs, and I haven't had any spark problems with a used EDIS ignition setup, and new OEM wires.
