I prefer the pic project approach in either of two ways.
1) Use a pic analog input to measure the O2 sensor voltage at the ecm and drive a display/leds or whatever based on the voltage. very easy.
2) Use a pic plugged into the odbII port sending the scangauge codes and displaying the received data on a screen or again driving leds. More difficult. But we know the codes reqd from the scangauge data. plus you could just plug this in like a mini scangauge.
I might have a go at a pic version of No 2 above when i have finished the A123 install and my multisubpack cycler.
If we get an accurate voltage reading via this then it might be able to corelate the voltage with the lean burn activation point so we could then have a display which showed how much throttle you could get away with before lean burn would drop out. i don't quite understand the relationship but certainly room for some experimenting.
