This page lists some applications that could be implemented with using large part of GenBoard HW (or as is) and considerable part of the firmware (but extension is needed):

Ok. I'm new to wiki, so this is going to be a mess. This seems to be about the most reasonable place to post (I'm more of a forum guy).

I want to develop an open source engine piggy-back controller. The idea is very similar to your project here, except I want to minimize initial tuning by taking inputs from the stock ECU. My target application is the Dodge SRT-4. We already have 4 different very well tuned ECUs. Many hours went into their testing and I want to preserve much of that. However, I want flexibility to tune my engine based on my modifications.

So, the plan is to have inputs for the fuel injector and ignition drives from the stock ECU and modify them slightly as needed.

For example, adjusting fuel injector pulse widths to trim out excess fuel at WOT when using W/I.

I don't know if maybe I'm re-inventing the wheel and there already is such a project underway, or what... Perhaps a modified GenBoard could perform this task?

Anyway, if you really interested in details, check out my long-winded thread at srtforums.

The first page summarizes most of the project.

thanks. sorry for the mess.
