Electronics

Here you can find information and schematics for some of the projects I've done.  They are categorized, as follows:

• Automotive Electronics - calibrations and toys
• Electron Tube Audio - tunes via fire bottles
• Home Automation - make your house kinda smart

Version 0.5

Posted on October 27, 2003.

10/27/03: Version 0.5 - tweaked the cold start tables, AIS tables, and other fuel tables.  The engine starts and idles fine, even when cold.  Decel mixture is good.  Fuel mileage is better than the ND cal was, though still below stock.

Version 0.4

Posted on October 16, 2003.

10/16/03: Version 0.4 - richened-up the part throttle curve at high boost levels and leaned the no-throttle curve some.  Also adjusted the cold-start enrichment curve down a bit.  The mixture looks pretty good for me.  The only outstanding issue is an idle surge when coming to a stop when the engine is cold.

Version 0.3

Posted on October 15, 2003.

10/15/03: Version 0.3 - reapplied the v0.2 changes to the real stock 1987 Turbo II calibration and tuned for 55psi of fuel.  I ended up with different curves that seem to be too rich during no-thottle decel and lean at part throttle over 12psi of boost.  Idle mixture is good, as is cruise and WOT.

Version 0.2

Posted on October 13, 2003.

10/13/03: Version 0.2 - richened up the top end a little, but may be too lean for you, as I forgot that my fuel pressure is 60psi right now.  Gas mileage seems to be good and it gets enough fuel all the way to 18psi or so, even at part throttle.

Version 0.1

Posted on October 11, 2003.

10/11/03: Version 0.1 - first working cal, actually based on the MP CSX Stage II cal (needs 93 octane).  Has trouble at cold start, as it likes to die a few times unless the throttle is blipped.  Could be a mechanical issue with my motor.
