any microsquirt guys out there?!!

I need some help with my setup and the microsquirt forums suck!! No participation on there. I'm having issues with the coil wiring I think? I know there a are some guys on here that have done this, but it's a shot in the dark. Please help if you might know something on this.

 

I'm running a 420a dodge neon coil. the same as gennro used on his efi bike. I've been trying to find info for the wiring. A lot of info for megasquirt, but not microsquirt. Very frustrating! I currently have the coil wired to pins 11 & 12 with the center of the three to 12v. I'm not getting any spark, but this could be a software setup, but I'm not sure? I'm just know learning tunerstudio, not much help there either. This is a tough project, but when done, really cool.

 

I have very limited experience with Microquirt personally, but I do know that the wiring is practically the same as the Megasqirt. I was a member of the FSAE Team at my school last year before I graduated and we ran Microsquirt for our engine. I know for a fact that the engines guys used the "Mega Manual" to wire everything and for tuning. (They did have trouble figuring out tuner studio also) I have set up two megasquirt systems before and the manual is very complete, you just have to be very patient and check every connection several times to ensure its correct.

 

That's just it, I'm not sure I wired it right? But, I appreciate it.

 

You have a build thread on here? I'm looking at running microsquirt on my xj750 at some point and I'm always interested in reading about other people's builds. What throttle bodies did you use?

 

Wow I thought original wiring harnesses were a biotch lol. Props for doin what your doin man, that looks hard lol

 

You might want to talk with this gentleman. I have a bike like his and have been following his thread.

Which version of Microsquirt? By memory the newest one requires you to use a ignitor to switch the coil.

I will dig through the info if you like?

 

Fibre is correct, the newer microsquirt (without the metal case) no longer has the onboard coil drivers.

Was only the other day reading a mega/micro thread & indeed necro'ed it because the subject interested me & I hoped someone was still doing it! That's where I read about the newer version needing a separate ignitor. I'll root it out & link it.

EDIT-: here it is http://xjbikes.com/Forums/viewtopic/t=3 ... quirt.html

Also from the info I read in that thread, I believe you need to ditch the second pickup coil if still fitted due to noise issues affecting spark & ideally make the wires from the one you use a twisted pair to reduce interference...

 

are you friggin' KIDDING ME?

really? what a mess...

i dont mean mess as in unorganized or sloppy (cause this sure aint sloppy!) but holy CATS man! thats a lot of stuff going on there...

 

I think it just *looks* that way because of all the different wire colours, when the loom's finished & wrapped in black it'll look a lot less scary

 

I'm using 2003 GSX-R 600 Throttle bodies

 

I know right! I basically have two systems integrated together. I actually have a high tech wiring harness for the regular electrical system that cuts down on the wires. It's a motoscope m-unit and eliminates turn signal relays and such. I couldn't imagine the wiring involved without it? At least twice as much as this.

 

Ok, I believe my coil(420a) doesn't have a ignitor. It's a dual coil in one unit with a three pin input. One input per coil & 12v for the middle pin on the coil. Is the ignitor something I can buy or is it something I have to build? I'm not finding the right info on microsquirt v3 homepage. I have the v3 microsquirt.

 

I found this. Is this the correct setup? I found it on a megasquirt forum.


ms-1 extra ignition hardware manual

 

I'm not sure about the setup (though it does look to be correct form a wiring standpoint), but I am sure that you'll need a heat sink of some sort for the ignition modules, and thermal paste between the modules and the heat sink.

 

I think I'm catching on now, maybe?

This looks a little better

EDIS ignition control for microsquirt guide

 

I think you've figured it out! You definitely need an ignitor for your coil pack. I've never read about the Ford EDIS system but that should work sufficiently well!

Some people run ls1/ls2 coils because they have a built in ignitor which may have lead to the confusion. Make sure you look into potential shielding and feedback suppression as a separate ignitor can add some noise into the system.

 

All you need is a transistor, although one with current control would be nice.

2 Old J121 modules off mitsubishis will work.

 

Personally I like the Ford EDIS4 system, tons of spark power (use dielectric grease when fitting the lead caps, I've known them to "explode" leads without lol) and over here at least they're so common scrap yards would almost pay you to take them away!

 

ok stop before you put that junk ford crap on your bike im running the same setup 420a coil with microsquirt all you need is to order the quad spark from diyautotune

 

Any hints as to why the ford is junk? (as per my last post I've found EDIS to be a very good system)

 

THANKS FOR THE TIP!!! I almost bought one last night.

On this setup, do you have to set the trigger wheel angle exactly? The Ford EDIS must be 90° ahead of the VR sensor when at TDC. Or, can you cout the teeth and set a trigger offset in tunerstudio? I have somewhat already welded the trigger wheel in place, but can be changed. What is your setup? Everything else is set to go on the bike except for this.

 

This site has a lot of information on Mega/Micro Squirt stuff.

I still say there's nothing wrong with EDIS, great system IMO with loads of power & cheap to buy. I'm still waiting for him to explain exactly why it's "junk crap"...

 

I talked to the guys over diyautotune any decided to purchase the quadspark model. I don't have to rewire as much & I can set the timming by software vs having to set the timming exact on the trigger for edis. They also told me that the edis is not a good choice for engines revving higher than 6,000 rpm. I don't know if this is true? But, I'll take the man's word. I hope to get it by Friday so I'll have the weekend to get this beast finnally started!

 

Being able to set the timing via software is a good advantage I'll give 'em that much! Not sure why it wouldn't be good above 6k but anyway, sounds like you found an easier solution timing & wiring-wise so all's good. Hope the fire-up goes well for you

 

Thanks! I'll have a video of the fire up when it happens.
