Megasquirt 3 Assembly for LS1 / LM7 / LSX

So last month I assembled my Megasquirt 3 with the expansion board that will allow me to run sequential fuel injection.
Sequential fuel injecting basically means that I can control the 8 fuel injectors individually. I ordered my MS3 unit from I decided to go with the unassembled version which saved me about $200 bucks. Looking back it took me about 20-25 hours to assemble they claim it should only take ~12 hours but for a n00b like myself I would say give your self at least 20 hours. Just to make sure you are thorough. This is something you wanna get right the first time and not have to go back and resolder different parts of the board.

Below are links to the instructions I used when assembling my Megasquirt for an LSx.

Step by step assembly instructions for MS3:

Step by step instructions for more general v3.0 main board assembly (I used this as a supplement for the main guide)

Getting the work area ready to role.

Soldering in all the resistors / diodes / capacitors

Plugged in the JimStim to test different point on the board to make sure its reading +5 volts on different parts of the board (see the assembly instructions for exact points). The JimStim basically simulates a running engine plugged into the MS3. This allows you to simulate an engine running log real time data from the Megasquirt without having it wired up to real motor.

Installing the MS3X (MS 3 expansion board)

Now installed on the top level above the v3 main board you see the MS3 daughter card (contains the sd card slot) and the ribbon cable connecting the daughter card to the ms3x (expansion) board that can drive up to 8 separate fuel injectors.

Setup the case and got everything wrapped up check it out! Flashed it with the latest C code and got it to sync with my laptop over USB and run the digital gauges.

Stay tuned the next post I will go into all the customizations that must be made to the MS3 to get it to fire and run a LSx (LS1, LM7)  type motors.

Megasquirt 3 Full Standalone

Just received my Megasquirt 3 full standalone kit. This will allow me to trash the stock computer on the 06 LS 5.3 engine and run a fully customizable ecu. With this ECU I will be able to run digital gauges and the tuning possibilities are endless!

Checkout this video of a MegaTunix (digital gauges software) connecting to a Megasquirt Engine ECU to power the gauges.


Pretty amazing

Here is a picture of my unassembled Megasquirt 3 with the expansion card for sequential fuel injection!

5.3L LSX On Engine Stand

A while back I bought my engine off of Craigslist for around $650 bucks which was a steal. It came out of an 06 Chevy cargo van and has 80k miles on it. It came with full wiring harness including the ECU and tranny controller. I recently got it mounted on my buddies engine stand he built.  That way we can fire it up before it goes in my car.

Still waiting on a few missing parts Mass Air Flow Sensor and a Starter before I fire it up. I will be sure to post a video of it running on the engine stand when I get it running.

Getting it from the short engine stand to the running engine stand.


In transit to the new engine stand …


Sitting on the stand just need to get the wiring harness all plugged in.


Wired it all up talk about a puzzle and also installed some new spark plugs NGK G Power pre gapped iridium's.




Looking pretty wild. I also just painted my TH350 and in the middle of rebuilding my kingpins for the front axle I will talk about painting my TH350 and my kingpin rebuild process in my next post!

Moved The Project To My Garage

Well moved the project over to my garage it had been sitting in Wesley’s garage since January that’s like what 7 months. So far picked up a few tools I will need and borrowed a good air compressor from Wesley. Here are some pics of the car on the trailer when we were moving it over to my house.


Looks pretty wild when you see it on the trailer.


Getting ready to role on over to my crib …


So far my blog hasn’t been getting much traffic maybe like 3-10 hits a day hahaha.

O well I’ll keep updating it for my own sake. Smile with tongue out

Wheel Spacers & Axle Painted

Ended up getting some Wheel Adapters 5 Lug 5in To 5 Lug 5.5in spacers 1.25". The 1.25 in spacing was the least I could find. Got them for $59.99 with free shipping from the seller gr8tseller888 on eBay.
This will allow me to bolt up the Dodge 20in Rims to the Ford Axle since they have different bolt patterns.
Used a 9in Ford 3rd member seal. Told O’Reilly to get me one off of a 78 Ford Galaxie.
Sprayed the self etching primer that way I can get a good bond.
Top coated with a semi-gloss black out of a paint can.

Rat Rod Riding On Air

The rat rod is riding on air finally. Finished painting the frame and rear end housing. Also got the triangular link all painted up.

Rear end mounted with the bags inflated.



Also finished cleaning up and top coating the radius rods and man was that a chore took about 4 hours..


Front end re-assembled


Painted The Rear End & Frame

Painted the rear end and frame a few weeks ago. Spent a ton of time sanding down the old metal and spraying it with a self etching primer.



Then finished it with a semi-gloss topcoat. Below is the finished product!



Pictures of the self etching primer drying on the frame.


Slowly but surely…

Rear Axle / 3rd Member

Found a rear end for my project car down in Washing, Missouri on Craigslist.

Picked it up in early May and about 2 weeks ago finished grinding off all the un-needed brackets.

It came off of a Expedition/Navigator.


Cleaning / Grinding



Almost ready to weld on!

The Lost Month of May

Well you might be wondering what the hell happened to Andrew and the Rat Rod project. Well the truth is I sold it its gone I gave up.



Just kidding … haha … What really happened is I didn’t fully understand the magnitude of what Wes meant when he said “Body work takes forevveerrrr”. Well I’ll give him credit he was right because it took almost the entire month of May and I’m still not done. Granted I’m a paduan learner and have been given the nickname mud puppy since I managed to spread body filler all over the car that never dried.

Anyways live and learn below are some recent pics of the body and how its coming along (I’m not done yet Sad smile )

As you can see its looking a ton better!

Body Filler / Bondo Nightmare

Well a few weeks ago I started filling the weld seams on the body of the car. When you use body filler you take the regular filler and you add some hardener to it and mix it together. The details on how much is the right amount of hardener is very vague.

So for the first batch I mixed in the recommend amount of hardener within two minutes it had already hardened while I was applying it to car body. So for the second batch I decided to use about 50% less hardener thinking I had used way to much. HUGE MISTAKE haha!! I noticed that the filler was getting tacky but was no where near as rock hard as the first batch after about 20min. I continued to apply it to the entire body and later called it a night.

Well the next day I get off work and I head to the shop to sand and add new filler on the body. Much to my surprise none except the 1st batch of body filler had dried. All the filler had the consistency of chewing gum. So basically I just applies .8 gallons of bubble gum on the car hahaa.

Here are some pics. It took about 4-5 hours to clean and remove the filler gunk. I used lacquer thinner and a wire brush drill bit to help get most of it off.


None of the below body filler dried. Sad smile




After 5 hours: Its back looking FRESH AND CLEAN back to step 1


The whole process was 1 step forward 5 steps backwards but I guess that’s all part of learning. So far I have re-applied body filler to most of the body and it has dried 100% I just needed to mix the filler better and make sure I had enough hardener. It should only take 10min for body filler to harden up.
