Reminds me of the racing days. Everyone I have ever known who had similar setup for racing also had COM port problems.

interesting
Glad you have the tools you need to give us even more info!
congrats

So, what's new with this pursuit?

Yes, I've just ordered an ELM323-based interface (obd to rs232). Now I'm looking into tweakable software with source. I don't like installing .exe files from little no-name sites. Of course Sony proved that you can't trust anyone anymore. But I digress.

If I'm able to find something useful, I'll consider contributing to an open source project.

Not much new to report with the tool.

I decided I'm going to do a VG experiment before I play with EGR. Also, getting the ForkenSwift going is a priority.

On top of that, it's getting colder now, which makes testing more difficult. All that adds up to: I guess I have no real plans to use it before spring.

I hope you'll post back with your experience getting yours operational.

I'm not sure which would be more nerdy, developing the ultimate instrumentation to know exactly what your ECU is doing, or to roll your own ECU. There's an endless amount of information there. It's cool but it comes with a stern geek warning.

I've wondered about that. But then I question whether I can improve FE through a custom computer over the OEM unit, without adversely affecting emissions.

We all know we can lean out our mixture and get better FE, but my unless the cylinder was designed for homogenous charge (a la Honda lean burn), won't you just end up raising NOX too much?

I'm sure you're absolutely right. I suspect that it would take some excellent instrumentation and time (read R&D) to tune a custom ECU to be better than OEM. I think the low hanging fruit would be the ability to make some of the tweeks folks here talk about (maybe a more automated engine-kill/fuel-cutoff). Then there are the tuners who burn new ROMs for OEM units.
