Anyone using MegaSquirt?

How about a pic showing the box and stuff?

You have maps, what about a wiring diagram??

dude, it would really easily work on a daily. THis car is driven stone-cold every damn day from my apt to the school parking lot, then for a daily backroads run every night. so it's really doing well. Plus, if you put it on a protege, I already have a program with hours and hours and hours of tuning for ya. it's really not that ballsy when you get into it.

Mateo,

I would like to run the megasquirt in a CBR and I would like to know if you could email me the material used to put together your system.

We can also talk by pm about it.

Nice nice job and great skills

Mateo,
you are using batch firing, right?
 
I saw your threads on the Megasquirt board, Mateo...

So, you haven't been able to get the spark to run off the stock ignition set-up? You switched to an older version of the EDIS igntion?

Its my understanding that is the only way MS works...
Guys Mateo uses the Megasquirt to control fuel.
It uses stock timing.
So all the megasquirt does is take tach input and dump more or less fuel in the engine. Right?

Now, why would someone decide to change the timing and what is it useful for? I am asking this because I know what timing is but I do not know why change or if it is bad to keep timing always the same with more HP.

Thanks again
 
Which version are you using, Yeller? One of my friends is installing one in his MX3, and he got the more recent MS v3. Definitly snap some pics of it. =)

nope, I can't figure out how to trick the coils into firing when i want them to, in order. what MS does is fool the ignition module into advancing or retarding from a mechanical base timing pt. It might be possible to get them to work, but EDIS cost me like 100 bucks, so i just said screw it, i know this works, I'll just do that.

Fede, timing maps are incredibly sensitive to pressure, boost, temperature, etc. it's not really a horespower level thing, but the factors that make horsepower indirectly.
Yes, I'm currently running fuel only, in batch fire mode. MS doesn't do sequential firing, simply b/c it's not practical, it doesn't make a damn bit of difference at >1000rpm.
I'm putting ignition in right now, so I'll be running full standalone within a week, hopefully.

flat_black, I'm using the V2.2 board, aka MSnS. Extra code 24s9 w/ EDIS control. Let me know how that MX 3 project goes, I'd love to lend a hand working out the kinks of MS!

Hi yellerandahalf, great work with your car. I will soon be buying a megasquirt and I would have a few questions to ask. I have been reading a lot about megasquirt and I have read most of your thread about megasquirt on both forum and I think I understood mostly how you did it but I guess I just want to be sure of my understanding ;)

So if I understood right, you reuse most of the original sensors. Was there anything to look for with them? Did you just tap-in into the wire going to the injectors? Did you get this EDIS module working?

I am going N/A but I think it should work good with a wide band O2 to keep the a/f ratio at peak. I will keep posted on your progress and hope to see some time sheet or dyno sheet on the monster your working on (thumb)
 
I asked someone once if they had megasquirt. They said sure, along w/like 48 other high quality DVDs... did I wanna borrow them?
 
ok....annnnnnnd your done. Anyways, I am just about to purchase a Megasquirt here shortly and i was wondering if anyone had some solid, cranking/after start enrichment/warmup enrichment maps that they could post. My situation differs just a tad from most you guys though cuz I'm doing this on my 98 Mazda 626. (hah) but don't go jumping to conclusions already, its already pretty heavily modded and impresses the hell out of alot of tuners in my area. ya....all my mods are in my sig. anyways, my car comes stock with the EDIS-4 Ford ignition system. Sooooo, theres really no modding there for me...except for the MSD Ford 4-tower Coil Pack upgrade, which is a direct replacement. (thumb) Anyways, other than my stock ignition system being different from the proteges, everything else is the exact same so if i could get those maps it would be greatly appreciated.

And just for whoever was having problems with the stock timing: The megasquirt can still use a MAF sensor signal. But the code in the Megatune configurator needs to be changed around a bit and a wire needs to be run from the MAF signal out put to pin X7. It's all explained here: http://megasquirt.sourceforge.net/extra/MAF_Stuff.htm

Besides, MAF sensing is MUCH more accurate than MAP sensing. MAP sensing just allows you to be able to tune higher boosted apps because the MAF's air flow capabilities have been maxed out. But up until that point...MAF is the way to go, especially if going NA. (rockon)

So you think the maf would be better than MAP. I was under the impression it was the other way around. I'll look into it a little more I think.

MAF systems are much more flexible in their ability to compensate for engine changes since they actually measure airflow instead of computing it based on preprogrammed assumptions(like the MAP does). They are self-compensating for most reasonable upgrades, as well as extremely accurate under low-speed, part-throttle operation. Another words, it makes tuning alot easier because you don't have to pull values outta your ass to make the thing run like you would on a MAP setup. IMHO, MAP tuning just gives you the false impression that your car is more tunable because you have to create a preprogrammed table for the computer to refer to. I dunno, theres alot that like MAP tuning and alot that like MAF and they both have their PRO's and CON's...I'm just saying that Megasquirt has the option for MAF which could be benificial to some peoples setups.

There's no way to "trick" your coils into firing at the right times for your car... This is because your car uses 2 coil packs and is distributorless. The only way for you can use just the megasquirt to drive your coils is if you have a distributor, thus meaning you only have one coil. This is cuz the MS outputs one combined ignition signal which on any distributorless ignition system, you have to have 2 seperate signals, i.e. one for each side of the coil which means that 1 signal fires 2 cylinders at the same time, hence the term, wasted spark. Sooooo, in order to create 2 seperate signals a microprocessor of some sort has to be involved(i.e. EDIS module), or some SERIOUS custom reprogramming and reconfiguring of the megasquirt board needs to be done. I'm not quite sure on the MS II processor being able to do this right now, but if not, anything is possible... But, as far as I know, this is the ONLY way to get ignition control on a distributorless motor(i.e. using some kinda of OEM ignition module GM, Ford, etc.)

SOmbody can confirm this ???


Any update from yellerandahalf ???? Any new since 06/10/2005 ?? what's happen ??
