Something doesn't add up there, 12 - 13 deg timing at WOT up to approx 5000 rpm?????
I'd say it would handle a lot more than that.

What he said ^ Awsome job there. Its about time someone looked into how Kalmaker does it. Currently I use Kalmaker to do the realtime tuning then re-write the adjustments to another memcal (thats not using the Kalmaker software), beats paying several hundred dollars for a security PAL each time I do...

if you have a bcm, you might be able to plug it to power, and attach it to the same aldl wire between the tech-1 and the car side connector, literally just hanging it off the side.. might be enough since its a 1 wire bus? This will work. I have even done it on an uncoded VT bcm/pcm combination Dave.

Narrow band and wide band, think of the words that are being used. "band" is like saying "range" as far as measuring Air/Fuel ratio goes, and the "narrow" and "wide" is like saying "small" and "large" So you have Small Range and Large Range...
