Cowfy - here is an interesting read about smog, California, and twin sparks. Biba started it and I was involved as well.

Biba - here is a discussion about the AFM to MAF conversion. Essentially, the AFM used by Bosch has a flap door and a small air passage. Many people have been unhappy with this device and want to swap it out for a more free flowing device to measure air flow. The problem is the signal back to the computer needs to change somewhat, since each device maps the signal a different way. This signal mapping device was discoved by JJ (junglejustice) and I had been reading the website for a while too. We get into a dicussion on how it works. Craig of Alfa75 fame also contributes.
