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?

Let me get up to speed on this awesome project. This is programmable EFI with ignition control together, correct?

I am interested in it. I will be building a 2056, ported heads, big cam/valves and custom exhaust.

There is still decision being made between ITBs or a custom single TB plenum intake (basically a four banger version of the Carrera 3.2 intake manifold).

Maybe the injection system will help make that decision.

The basic idea behind what i am doing is to simpliy the replacement of d-jet with megasquirt while remaining as close to stock apearance as possible. It is digital and fully programable so you will not be tied down to stock cams and displacement. Basically a good cheater system. My idea is to supply it in a fuel only configuration in order to keep the install as simple as possible for stock system replacement however being as that it is Megasquirt based and running the MSnS Extra code someone could add ignition control or a ton of other features if they were so inclined. I am running my autox car with ignotion control and a wideband O2 sensor with target AFR tables. Once you start geting into all the extra features though things can start getting complicated so i would rather just be supplying the base to build from and anying else people want to add is up to them. check out the MSnSe feature list, its pretty exciting.

As the part of my goal is retaining an appearance as close to stock as possible you might be more intrested in just doing your own megasquirt build. Things are a lot less complicated when you are not tied to the stock wiring harness and stuffing everything in the stock ecu. Yes, what i am building could be made to work with what you are planning, but if you are not concerned about looking stock with the ITB's or custom manifold I think it might be better to go with a custom wiring harness as well and not mess around with the d-jet one.
