There would be 4 injector drivers (peak&hold standard or optional, not yet certain) and 4 ignition drivers (high current or logic level).
Since there has been a request for it, this would be put in a ruggedized enclosure (http://www.cinch.com/products/transport ... -enclosure). While this may be somewhat more expensive, it does provide an automotive connector and the needed heatsinks and does protect all the electronics in a sealed box.
I am also considering an option which would add an internal data logger and add additional I/Os which could include a stepper motor IAC controller.
What I would like to know is if this is something that would interest people here. I still need to do quite a bit of work to know exactly how this will fit together. If I can get interest from a sufficient number of people (here and on a couple of different forums) I'll make this.
There is a thread on my forum on this (http://forum.jbperf.com/viewtopic.php?f=12&t=50) so it might be more appropriate to ask questions or make comments there but I think it would be ok to mention your interest here.

The main issue is that the Cinch box requires specialized tools to close and open. So there would be no easy way to have configurable hardware options (either through jumpers or DIP switches). And to cover most of the inputs (sensors) and outputs (injectors, ignition, idle valves, ...) there would either need to be some hardware configuration or a bunch of connector pins used only for some setups. However, the Cinch box doesn't make it possible due to not being easy to open or close and due to the somewhat limited number of connector pins (at least for the redundant options setup).
And having each box configured before sending it to the customer is not a practical solution because it requires way too much handling and the customer would be stuck with a box that only works with one setup (unless returned to be reconfigured).
So the options are to have some restrictions on what the box is compatible with or change the enclosure/connector to make it more user-friendly. I prefer the second solution but then that also means that I have to find a sealed alternative or have a less rugged product. It would be good to know what people see as being the top priorities: ruggedness, automotive connector, compatibility with most OEM hardware/sensors, easy configurability, full-featured,...

Basically there will be a very small initial run (6-8 units) to gauge interest and as a proof of concept. What happens after that will depend on the interest. The feature list has intentionally been kept somewhat small to speed up development, keep the cost low (hopefully) and maintain a relatively small footprint.

Probably around $500.
