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 see I'm still the only one voting in the "cost is no object" category. Let me clarify.

I am assuming this would be a full bolt-on replacement of carbs. With new carbs running, what, $750? it would be worth at least $1,000 maybe $1,500 to have a fully tuneable FI to accomodate my Raby engine. With Jake's alternative FI adding $4k to an already healthy investment I wasn't quite ready to make that leap when I got the engine. Maybe at the required 60,000 mile refreshening in 5 years.

But if a fully functioning, programmable option were available soon . . . I'm already tired of hard starts at 50 degrees and lousy mileage. Unless McMark can work his magic on the carbs (IMG:style_emoticons/default/piratenanner.gif)

50 degrees? ouch, that is really not very cold at all to be having issues.

As i said earlier my initial idea was just as a d-jet upgrade and converting back from carbs is a bit more work. It is do able for sure though, and if money is not the issue, getting everything you need for well under 1000 bucks using the d-jet intake parts should not be a problem, just more work.

What size Raby motor are you running? What bolt pattern on your heads? My only concern with higher power motors is that i dont have any data as to how much the stock d-jet intakes can flow, or if it would choke the power of your motor. It is something i would like to find out though. Perhaps Jake has done testing along these lines? I am planning a 2056 at the moment for testing but that is going to be a little ways off.

Another issue you might come across with a Raby motor is the likely hood of Jake supporting this setup being rather low. I may be wrong, but i believe he had a bad experience in the past. I would love to work with him on it to get his support as i see a lot of potential for this type of setup but as he already has an FI setup that he endorses I am not sure what he interest in that would be, again i am guessing probably low.


I would definitely be down to figure something out for you though.
