Thanks for making this video. The way you broke this down in addition to sloppy's videos really helped me to decide to go with a micro squirt! Going to order it tomorrow and likely won't install for a bit but definitely going to follow this guide! Thanks!
thank you so much for this video it really shows step by step how to do it and thanks for giving the wiring diagrams for all the coils injectors and sensors. I couldnt find the wiring diagrams anywhere forums are filled with information but since photo bucket went down the shitter all pictures in those old posts are lost which sucks.
Hello I'm trying to put a 1995 3.8 buick super charged v 6 in my 1956 cj 5 m22 4 speed . I took the harness , ecu , and fuse box . I just want it to run and not be so complicated . The harness was removed completely and still on the engine . My son friend is going to give me a super spurt. Can you please give me a little advise . This was such a video you are so smart .great watching good luck on all your future projects. David
Awesome video. Thanks. Just getting my 280Z painted and back together after 24 inches of water with Hurricane Harvey. I have a Spectre EMS-Pro I’m using to run fuel and spark with LS coils. If I’m correct, it’s a modified ms2 like the micro squirt. Your video is a big step to getting it wired. Thanks again.
My ls1 swap is not using a MAF but instead a MAP. Should I use the maf connection and plug it in to the map? The manual says I can use one or the other but I'm not too sure
Awesome video man, thanks for making it. I just fired my turbo 5.3 on microsquirt and it is RICH... I didn’t have a wideband on it yet and I honestly just got it used from a guy on a ls marketplace and have no idea what tune is in it. Lol I tried to download one of sloppys tune from his cabinet but it says it won’t take it in tunerstudio. Idk I’ve got a lot of work to do before I get it smooth, but thanks so much for making this it helped me out a bunch.
Hey I appreciate all the help before running in to some weird stuff. I was tuning a little bit an the car cut off. Now when I try to start it I turn the key on the pump cycles but pcm won’t connect to the laptop try to detect it etc. I get nothing. while they key is still in on position the pcm cycles fuel pump every 15 seconds. I thought it was a wiring issue I’ve tried multiple 12v connections to power the system and still the same results. Made sure grounds were good. Changed the relays as well. Still the same. Nothing fixing this issue.
Do you know of any way I could test the iac motor ? Or how I can see if the stepper adapter I have is working ? I have a meter I wired the iac adapter myself like the rest of the harness but a new problem arose where in tuner studio when I use the can bus test to test the iac it communicates like it’s supposed to on the gauges but it doesn’t matter if it’s in the home position or run position it has no affect. So basically right now I have no iac motor and it’s stuck so far open it wants to idle at 1900 Any help is greatly appreciated
I know this is SUPER dated. But i noticed the back of your MS ecu says LS1 24X modification. I cannot find any info anywhere to comfirm my ecu will work with my LS, or what i have to do in order to make it so. Any info ?
@russmurdoch8547 figure out where it was purchased from! The ms2 gets modified with resistors to run the ls, it is something people used to do but they just sell them done now
I'm looking to trigger a relay for electric fans via the Microsquirt on my 5.3L LS. It looks like since you need to use the LED pins to trigger the coils, that there are no other spare outputs to use unless I opt out of using IAC/FIDLE. Is this the case? I can't find anything in the documentation that mentions using WLED/ALED to trigger the coils. What am I missing?
You will be out of outputs unfortunately, but no need to worry! Buy a fan switch at desired temperature and install in your head with an m10 to npt adapter. That fan switch then grounds a standard bosch relay and turns on your fan!
Does anyone know if you can put the resistors that are supposed to go inside the Microsquirt, outside after the connector instead of inside the module? Amazing video man. Very detailed.
Quickly reviewing here: CANH, CANL, VRIN2+, SPARE, FLEX (now using it for my 2step,) SERIAL RX, SERIAL TX, BOOTLOADER, OPTOIN+/- and I think that's it! Note that I've got the IAC controller which takes up a few more wires.
As far as what I did with them I cut them to about 2ft in length and just hid them in the harness incase I ever had to connect to them again. This was the case for the flex wire which I've got rigged to a clutch switch. In tuner studio you can setup 2 step to run when this wire is grounded so my cluch switch grounds this wire and boom, I've got 2 step with clutch depressed and throttle over 90%. This actually can cause problems though because I shift fast and it will hit the 2 step between shifts occasionally, so this year I'm going to move the two step to a thumb controlled button.
Hi, great video! I about to order my micro squirt for my 2004 6.0 LQ4 swap into my 72 Nova naturally aspirated. I pulled a drive by cable throttle body off a junk yard motor to convert from the drive by wire Throttle body. Question about running the IAC with micro squirt. When you said " Your welcome! You can only do throttle by cable with a micro. The iac wiring is simply a seperate module which allows you to use a stepper iac which is essential to making it run nice :)" Where do I get or buy a IAC separate module? Sorry Im newbie confused. So is it just a way of wiring off the micro squirt or an actual separate IAC module "I have to buy somewhere" that works with the micro squirt? Thanks!
so for a straight 6 like from a datsun l28et i would need to wire the inj1 wire to injectors 1,3,5 and inj2 to injectors 2,4,6. Im also guessing that i would only need 1 signal wire for the coil since it has a distributor?
Correct on the injectors. I'm not sure how a microsquirt could control a distributor. It's got logic level coil outputs meaning its replicating a digital computer signal more or less to fire the coils. Get yourself a crank sensor and then run individual coil packs from an LS and plug the distributor hole :) I bet that is actually cheaper to do than even trying to make the distributor work, plus you can control timing way better with coil packs than the distributor.
Can the MicroSquirt harness be run through a bulkhead connector through the firewall? If so, is there a recommended connector or a recommended wire count?
Really need to get around to buying a Micro for my 4.6 2v; my setup will be a bit different but in some ways the same, I rigged up some LS truck style coil packs, but I have a 36-1 trigger wheel; also LS is my throttle body (I know, mismash of LS and Ford parts, what am I doing with my life? lol). Where'd you get your MS from? They seem to have gone up in price a bit?
Hello, maybe you cant help setting my eclipse 2000 turbo, i have 4g64 with microsquirt, everithing its fine but when i start the car sounds awful. Of course I can pay you for help me with that, Somebody tell me its timing problem. But i am not sure. I live in Costa rica but i dont now if we can do it remote.... Blessing
Did you get the microsquirt setup to run the ls? Try the red wire for now with a temp connection. When you try and crank the engine over see if your rpms register, if they do you're fine :)
On the coils ground I read that all of the sensors need to ground at the micro squirt but is it okay to ground both of the grounds from the coils to the block or does one need to go to the microsquirt thank you in advance and great video
EVERY one of my grounds goes to the same point on the head. Technically speaking the ecu is supposed to be grounded directly to battery and I believe the battery acts as some sort of a "damper" if you will for voltage surges
Westcoast Wrenchin' thank you for the super quick reply this my first install and the coils seem a little tuff to understand but your video and diagram make sense but after reading and reading the manual and watch megasquirt video on grounding the ecu this was one of my questions the first time around always seems to be the hardest then it gets easier on the second thanks again I don’t usually post questions because I don’t get responses so I really appreciate it
@@Mrvalle420 you're welcome! They seem complicated but they're not. Your controlling a high voltage monster with a just about zero voltage tiny wire so the wiring gets funky 🤣
Westcoast Wrenchin' after some more reading in the manual I did find the gm Ls1 (24x) coil wire diagram it’s not as good as your diagram but it has a odd component a 1k resistor on both the “WLED”&”ALED” going to the tps vref did you have do that or just run it without
@@Mrvalle420 No i didnt. All the microsquirt ls are exactly as my video depicts. I believe the resistor your talking about is for an ms2 and not a microsquirt. A microsquirt is a privately made product which utilizes an ms2! The microsquirt has some internal modifications to work with the ls. Hope that helps!
Do you have an idea as to why I’m getting a bad signal on my composite logger with no spark? The red line in the composite logger has waves just like the blue rpm ones while cranking. It’s a 24x engine and I have everything wired exactly as the write-up on LS1Tech says and it’s set to LS1 ignition capture. It was running for a while, now it has no spark while cranking but has spark in test mode and if I change my ignition settings to toothed wheel 24-2 it will try to run. I figured it was interference so I rewired my crank position sensor, added another layer of shielding and grounded it, and I’ve tried different crank sensors but the results are the same. I can send you my tune or pictures of my settings if you have time to look at them
Westcoast Wrenchin' I had to pull my transmission then when I reinstalled it the truck no longer had spark. The transmission is a full manual valve body though so it’s not electronically controlled and I didn’t change anything else. I had this same issue before that and I put some foil tape around my crank position sensor wires then it ran but now I have no idea why the issue came back. It’s been about a year and I haven’t been able to figure it out or find someone who knows anything about Microsquirts
Sure, why not? All you need to run a micro is a crank trigger really, if you've got that then you can use ls coils and pretty much do anything you like! That's what makes it so cool. It's so generic you can fuel inject anything!
Hey man thanks for your video! I have both a microsquirt and a msd6010 ignition box, I'm wondering if I'm better keeping the msd for igniton or going with the micro in wasted spark...Someone knows if one is better than the other?
Definately use the micro for ignition. That way you can datalog your ign and fuel together seamlessly. Wasted spark works like a dream dont let it scare you!
Thank you for creating this video. I have a 2006 5.3 LS and I am on the fence about whether to use throttle-by-wire or throttle-by-cable. Your description of how to connect for idle air speed; is that for throttle-by-cable or throttle-by-wire? Is there a preference?
Youre welcome! You can only do throttle by cable with a micro. The iac wiring is simply a seperate module which allows you to use a stepper iac which is essential to making it run nice :)
So is this essentially a complete replacement for the stock harness or do you have to somehow wire it in? I know you need the plugs but I'm not sure about the rest
@@WestcoastWrenchin that sounds good. I assume there's a wiring diagram that you just cross reference with whatever diagram belongs to the motor you plan on using it for. I want something to be able to tune and stuff and my car being a v6 and 34 years old, there aren't many options especially if you want to turbocharge it like me lol
@@nessabush1986 all you've really gotta do is get the crank trigger correct and run ls coils and I'm sure you could make most vehicles run. Some distributors can work too
Hey, quick question from a fellow Canadian! You mentioned that you paid around 400$ for the ECU, I was wondering where you bought it from? I'm considering buying one off eBay but it comes at around 550$ with shipping & duty fees, but I'd be happy to find one for 400$ + shipping lol
That's an interesting idea. My theory behind this was to keep fuel flow relatively constant through the rails instead of having one bank flow, then the other, then the other etc. I think that drastic flow changing would leave me with a less than ideal result. I did some research into this when I built my first one and sold myself on the 2 on each bank theory, but lots of people fire one bank at a time and it works just fine! I really would like to know more about this though.
@@WestcoastWrenchin So are the injectors fired at correct times per cylinder or is there always 4 injecters firing at the same time? the wiring diagram to me shows your piggy backing 4 cylinders per set if inj wires.
@@neddyairsoft3972 they fire four at once, they are not timed per cylinder. This is pretty standard on older efi and actually cools the valve. When you calculate how many times per second injectors fire you will see that it is almost negligible in terms of efficiency, especially on a hot rod
could use a ford edis 8 Module and coil pack microsquirt and then mount the coil pack on say the fire wall that would work i am thinking A...my projects are 1984 supra 5mge turbo and 5.3l k1500 truck thanks man a lot a lot was good to see one use something vs reading the book only God bless Jesus is my co pilot ;]
i appreciate you appreciating me, also Mike is THE MAN
Thanks! Mike is definitely a legend, before the MS I almost went with a carb 🤣
This was an absolute pleasure to watch....was going to go with Fitech or Fast, but will now try the Microsquirt....

Im interested in learning how to use micro squirt for only the fuel side on a foxbody mustang and use Msd for the ignition side.
Throw on a crank sensor and do individual coils!
My ls1 swap is not using a MAF but instead a MAP. Should I use the maf connection and plug it in to the map? The manual says I can use one or the other but I'm not too sure
Microsquirt is speed density no maf must use a map
So the maf connection they provided should be connected to the map instead? I bought the pre-made harness
What about fuses?

So is this essentially a complete replacement for the stock harness or do you have to somehow wire it in? I know you need the plugs but I'm not sure about the rest
Its a complete new harness where you solder on the old plugs
@@WestcoastWrenchin that sounds good. I assume there's a wiring diagram that you just cross reference with whatever diagram belongs to the motor you plan on using it for. I want something to be able to tune and stuff and my car being a v6 and 34 years old, there aren't many options especially if you want to turbocharge it like me lol
@@WestcoastWrenchin also how does it wire into the fuse box?
@@nessabush1986 all you've really gotta do is get the crank trigger correct and run ls coils and I'm sure you could make most vehicles run. Some distributors can work too
@@nessabush1986 just a main power wire really
I have a 318 magnum that im going to run a microsquirt on.
did you use vr1 or vr2 wire for hall sensor?
e34Boat vr1
thanks, one more question: do i use the yellow or green wire from the vr1?
ohh it was on the video :D the yellow wire... thanks again!
My vr1 wire has red and black in it not a yellow so witch one would I hook up to the crank sensor?
Did you use a maf?
Nope, speed density running only a map
Hey, quick question from a fellow Canadian! You mentioned that you paid around 400$ for the ECU, I was wondering where you bought it from? I'm considering buying one off eBay but it comes at around 550$ with shipping & duty fees, but I'd be happy to find one for 400$ + shipping lol
This was a couple years ago! Covid tax perhaps
@@WestcoastWrenchin Ahh that might explain it! Thanks for the video by the way!
Great info!
You should have wired the injector outputs to one side only, this could give you per-bank o2 feedback :)
That's an interesting idea. My theory behind this was to keep fuel flow relatively constant through the rails instead of having one bank flow, then the other, then the other etc. I think that drastic flow changing would leave me with a less than ideal result. I did some research into this when I built my first one and sold myself on the 2 on each bank theory, but lots of people fire one bank at a time and it works just fine! I really would like to know more about this though.
Understand wanting to keep the rails balanced but any significance to the cylinders you grouped, (1,4,5,8) and (2,3,6,7)?
jvan100 Nope, just did two on each rail.
@@WestcoastWrenchin So are the injectors fired at correct times per cylinder or is there always 4 injecters firing at the same time? the wiring diagram to me shows your piggy backing 4 cylinders per set if inj wires.
@@neddyairsoft3972 they fire four at once, they are not timed per cylinder. This is pretty standard on older efi and actually cools the valve. When you calculate how many times per second injectors fire you will see that it is almost negligible in terms of efficiency, especially on a hot rod
thanks for your video, and good working
could use a ford edis 8 Module and coil pack microsquirt and then mount the coil pack on say the fire wall that would work i am thinking A...my projects are 1984 supra 5mge turbo and 5.3l k1500 truck thanks man a lot a lot was good to see one use something vs reading the book only God bless Jesus is my co pilot ;]
Who here has put a microsquirt into a MK2 VW?
I don't know but in the manuals, big manual, had refereces to vw, mk3, mk4, and some parts of them
is this wiring the same for 58x and 24x engines ?
Yup
@@WestcoastWrenchin thanks for the info and quick response!
