Got this in email today, since I bought my MegaSquirt II from DIYAutotune. Seems they now have a plug and play, no additional wiring or components needed (in most cases) ECU replacement based on MegaSquirt that works with more than 40 cars.

The Miata kit is only $460.

Now Available! The DIYPNP EMS!
Read up on these pages, and kits are ready to ship here in our shopping cart.
Feature packed DIY-oriented PNP EMS System available NOW for a stack of cars, and soon for an even bigger stack.
Acura. Audi. BMW. Dodge. Eagle. Honda. Hyundai. Mazda. Mitsubishi. Porsche. Subaru. Suzuki. Toyota.
The initial targets of the DIYPNP.
DIYPNP - The Standalone PNP EMS for just about anything...
What is a DIYPNP?
(Taken from the DIYPNP FAQ located here)
The DIYPNP is a Do-It-Yourself Plug-N-Play Engine Management System. It is made up of three main pieces that allow for an incredibly flexible and modular system for building a plug-n-play EMS for a plethora of vehicles.
MicroSquirt Module- At it's core, the DIYPNP is based on the MicroSquirt Module which is a MegaSquirt-II Processor based ECU on a credit card sized PCB. The DIY element of this EMS comes from the fact that you assemble it yourself from a kit of components, soldering the unit together and then adding wire jumpers to route the signals to the connectorboard to match the needs of your car. The assembly is not nearly as complex or time consuming as a standard MegaSquirt ECU kit assembly, there are fewer components and all components are sized so that they are easy to solder (no tiny transistors here).
Mainboard- We've taken the awesome capability of the MicroSquirt Module, combined with the MS2/Extra firmware, and built out a mainboard that adds a very nice featureset including pretty much everything we get asked about on a daily basis by our customers. You've got dual ignition inputs and up to four ignition outputs (hi or low current, allowing for Coil-On-Plug for up to a 4cyl engine or wasted-spark ignition for up to a V8 engine. Distributor based ignition is of course supported as well. Knock control, boost control, 4 spare inputs and 4 spare outputs for driving fans, intake butterflies, on/off variable cam systems, whatever else you can imagine. There are more features too, check the features and documentation pages for full details.
Note-- All of the primary Inputs/Outputs are brought out along the edge of the mainboard that lines up next to the connector board.
All common ignition input/output pullups are as simple as they could be with a resistor network in place ready to setup.
Connector Board- And then the last piece you need to know about is the connector board. This is a small PCB that slides into the same slot as the mainboard and lines up right next to it. It's usually not much more than a breakout board for an OEM style connector that often fits a stack of vehicles as many of these connectors were used by multiple manufacturers, and often on multiple vehicles/engine families at each manufacturer. Sometimes we may fit an extra circuit on the connectorboard if we've found that the vehicles that use that connector typically need a particular circuit. An example of this is the Bosch Motronic 55pin connectorboard, which hosts a circuit to control the 3-wire IAC valve that is common in vehicles that use this connector.
So after you handle minimal assembly on the mainboard, you do a bit of research on the harness pinout in your vehicle (or download a spreadsheet of pre-researched info and just check it for accuracy in your application), and you use this info to run a handful of jumper wires from the mainboard to the proper breakout pins on the connectorboard bringing the signals in/out on the proper pins on the connector. This is what makes the DIYPNP so easy to apply to such a broad range of vehicles. It's basically a set of PNP EMS building blocks, with awesome results.
You want boost control, run a jumper to the input and to the output. Turn it on the in the software and tune it.
You want to convert your engine from it's stock distributor to wasted spark or COP, add the proper crank/cam trigger wheels to the engine (you might have what you need already inside of that old distributor) and wire those sensors up to the DIYPNP, then wire the ignition outputs up to your coils, set your timing and tune it.
The flexibility is massive. And if we didn't include a circuit you want, we've got two large proto areas on the mainboard (one is under the uS Module) and in some cases there is a third proto area on the connector board if we had the extra space.
There will be three DIYPNP Models released initially. The N42, the N76, and with maybe a slight delay, the B55 model. These three models will potentially support 40 or more vehicles, and we didn't even research the more obscure stuff out there.

Note that some models above had computer controlled automatic transmissions - if this is the case for your car, the DIYPNP will not be able to control the transmission beyond control of a basic lock up torque converter. If you have an automatic transmission, please check before ordering.

We'll be quickly following with more models. We're eyeing the connector used on:
* Nissan 240's
* Another (52pin) Nippon Denso style connector used on S4 RX7's, Supercharged 4AGZE MR2's, and Gen2 Supra's
* The 35 pin Bosch Motronic Connector used one a handful of cars, mostly European.
The Miata kit is only $460.
