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?

it would have to be plug-and play for the most part, to switch back from carbs.. not just the ECU, a complete "kit"

but compared to used dells, or new empi carbs, $500 for a modern FI setup would be almost a dream for a carb replacement... personally, I think the more refined the kit, the less after-support would be needed (IMG:style_emoticons/default/confused24.gif)

I was not thinking so much along the lines of switching back from carbs as i was just modernizing the d-jet system on existing cars. I have done one install already on my friends 914 switching back from carbs and you wind up with a lot more to deal with, including possibly pulling your fuel tank to unplug and replace missing fuel return lines, changing back to a high pressure pump, hoping that the used d-jet system you picked up has useable parts and injectors that are not leaking from the body. Plus with carbs there is a much greater chance that engine internals have been changed so any pre made fuel map goes right out the window. Doable yes, but much more involved

That being said though, the d-jet parts required to make this work are usually not that expensive and are relatively easy to come by, so it might be an option for a carb conversion kit. I am not sure I would want to be the one supporting it though.

I totally agree that a more refined kit would need less support, that is why I plan on a lot of testing and development based towards a specific applications. There are WAY to many options available for me to even attempt to support them all. I am just aiming for the most common and useable ones.
