I'm sort of new to this whole EFI scene.  Is it true that most of these 
ECUs have rather modest (16x16) tables?  I assume the primary variables 
are TPS and RPM, with substantial input from various other sensors 
(coolant, ari charge etc) which act as modifiers for enrichment 
profiles, etc...

My Chevy Injection book (don't recall the exact title) implies that all 
the tables are 4x4, in particular, the integration and "BLM" block learn 
tables.  That seems really sparse!

If so, why do we find 32K eproms and whatnot?  Whats in the rest of the 
eprom?  Is it all data or is there code there too?  Any urls for this 
stuff?

Is that all there is? (he asks the naive question...) :)

Thanks loads!
