but it was kinda the bad seed (first year run duckups). the new generation
gneIV have a different processor than the years prior... but that doesnt
mean they are more powerful.. they just do more instruction at the same
speed. plus they removed the transmission function to its own processor
so now a ECM (engine control module) and TCM (transmission control module)
will free up processing time...

The E38 operates at 59 MHz, with 32 megabytes of flash memory, 128 kilobytes of RAM and a high-speed CAN bus, and it synchronizes more than 100 functions, from spark timing to cruise control operation to traction control calculations. The E38 works roughly 50 times faster than the first computers used on internal combustion engines in the late 1970s, which managed five or six functions.
where are my DOS 3.03 disks... hehehe
