Gauging interest for PnP Megasquirt solution, MS anyone? Options

[JamesM]

For my most recent Megasquirt install i went a different route and had some mini-MS boards produced. It did not make a lot of sense to just have one PCB printed so needless to say i have more then a few empty boards laying around. Now i am trying to decide if it is worth my time and money to build these boards out and sell them as a plug n play solution for d-jet cars.

For those who don't know, mini-ms is electronically compatible with megasquirt 2.2 however the components are arranged tighter on the board and it integrates the relay board all on a form factor smaller then the original MS. My first couple of installs i used a standard megasquirt 2.2 with relay board and DB-37 cable but the mini-ms seemed like the better way to go so that is what i am playing with now.

The setup i a running right now looks almost stock, the mini-ms is enclosed completely in a gutted d-jet brain and plugs directly into the d-jet harness. the only difference from stock is a MAP line running to the brain and the 2 injector ground wires being run back as well. You have to look close to tell its not stock, however i have a feeling i could make it even more stealth by hiding the MAP sensor in an old MPS in order to get rid of the vac line to the ECU. I just have not cared enough to cut up an MPS yet.

The great part about this system is it makes troubleshooting way easier and eliminates the need for stock trigger points, MPS. ECU, decell valve, and cold start injector, though they can all be left in place if desired in order to appear stock. It also allows for cool things if you desire like closed loop operation with a wideband O2 sensor, spark control, rev limiters, traction control, and a bunch of other stuff depending on how far you want to take it. It can be tuned around just about anything, so its great if you want to change cams or go bigger on your motor and still look stock.

So is there any interest out there for this sort of thing or should i just dump the empty boards on ebay or something?

James,

What parts would need to be replaced in your bolt on kit?
I would assume it would all be in the box for me to bolt on.
Base map to get it running.

From there I can tune it.

I am ready now and I have a 1.7 I am about to pull out of my car for a 2.0 liter....
I will be happy to play with modified motors and your system
I will learn it on the 1.7 and then modify it.

When can I have one...no warranty needed...I suck at soldering.

Right now if you already have a d-jet system, its simply a matter of swapping the ECU and TPS though i am currently looking at ways to eliminate having to swap the TPS for stealth installs. If you dont mind doing the tuning you could even put which ever d-jet parts you like on any engine, ie. use 1.7 injection parts with drilled intake runners on a 2.0. We even did my buddys using the 2L bus intake due to the larger runners/plenum. If you are not worried about a stock look there are really a lot of options you could play around with.

As far as a time table goes right now its hard to tell as i have been pretty tight on free time. I sit in front of a computer for my day job, so i have plenty of time to solder boards, i just dont have much time to test the modifications i am working on in my cars. next week i should be able to test my latest changes and then i could proabably give you a better estimate on time.


As far as soldering goes, having a good adjustable temp soldering station and the right tip on the iron helps a lot.
