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?

I'd be intrested, I'd also like the Spark Control.

I've been looking at the SDSEFI and at $1,750 for everything needed.

I already have the ITB from Extrudbody.

If your looking for a IDIOT to do some testing, I think I qualify. (IMG:style_emoticons/default/av-943.gif)

I'm in SoCal so thats close to sea level.

Running spark control and ITBs would definitely be getting away from the plug n play and stealth aspects of what I am going for. Sure it is doable, but the only thing resembling d-jet at that point is the case I stuff the ECU into. I would say if you are going that route just use a regular MS/mini-ms setup with your own wiring because there is no point in trying to pretend it is stock. I have thought about making a bolt on kit along those lines however it would be $$$ due to the ITB’s and custom wiring harness, and I feel might have less appeal. I imagine fuel maps would be pretty different on a car running ITBs as well. If you want I could make an ECU in the standard mini-ms case using the Ampseal 23 connector and perhaps you could get Jeff Bowlsby or someone to make a custom wiring harness for you. You would be on your own as far as tuning goes though.

I would like find out what the advantages of ITBs on an otherwise stock motor would be though. If anyone has any input on this I would love to hear it. To me it seems like it might be more trouble then it is worth on a street car.
