i was sitting back one night, reading the forums, and thought about the LA2 vs the LA3. I was thinking about the 15psi in 1st and 2nd, and 11 in the rest...the thought...how the hell does the EEC know what gear the car is in?

Because it is almighty, it controls everything, it is the brain that controls the heart, the eight valve, four chamber heart.

I think the EEC casn figure gear by 1. rpm from the ignition and 2. speed from the VSS (vehicle speed sensor)

Pete is correct.... easy to determine what gear it is in based on speed input from VSS and RPM input from the PIP. It would be interesting to see what the EEC would do (with the stock BCS system intact) if the gearing was different, like 4.10 or 4.56 out back, or if massive wheel spin was present.
