Update: Project had a setback a few months ago due to some bizarre bad luck.
For years I always left my car unlocked at home as we live off the beaten path, some apparent kids cleaned out my car one night back in April, took the change in the ashtray and my ultraguage, my OBD telematics logger, and the laptop I was using for logging data with a graphing app. We found the ashtray just a few yards from the driveway, but nothing else. Blew my mind since aside from the laptop nothing was really flashy (my cobbled boxes and cables tucked in the glovebox) but they grabbed everything cables and all. I have much of my notes, just lost some info I can gather again. and some tools I was still using!
Since the initial vision for my project hit some frustrating barriers ( intellectual property crap) I kind of scrapped the OE rework, and am currently researching piggyback options. Hopefully will spring into a new Aveo project. Looks promising , well makes sense in theory and Jack from Dastek/Unichip seems confident I can figure out the sub mapping differential tables for timing curve and a power enrichment curve to play with. All new to me, but about the only low buck option to have the drivability I am after, and not drop $2,000 into aftermarket/stand alone EMS. If all pans out with the wiring nightmare of a piggyback, I may have a good foundation to add a small hairdryer under the hood of my LS. One of these days!
