REFLECTOR: Carburated Auto engine

[NMFlyer1 at aol.com]

I had the same options when I designed my V-6 powerplant.  There are  plenty 
of computer programs (specially for the LT1) that tuning and monitoring  the 
EFI system are relatively easy. My sole concern of the EFI system is the  main 
processor.
 
 Most modern ECM's do have a "limp home mode".... that many don't  completely 
understand. The "limp home mode" only works if the system has  
malfunctions/failures in the sensors.  IT DOES NOT HAVE A BACKUP IF THE ECM  ITSELF FAILS!!  
Since I have had 3 seperate computer failures, on 3 different types of  
automobiles, all without warning. That was unacceptable. 
 
There is no doubt that a computerized EFI would be the most efficient. It  
was just my choice not to trust the processor.  
 
By far, the least efficient would be the carb.  But; they are the  good ole 
technology. 
 
I chose the multi port Airflow Performance system for my own application,  
but I believe the Ellison Throttle body is a good choice too.  
 
All the best,    Kurt
