[Diy_efi] RE: batch or not to batch...

[John Smith1882]

There have been quite a few discussions on this across the 'net that I've 
seen. The concensus seems to be that SEFI's biggest benefit over batch or 
bank fire is cleaner idle and low RPM/cruise emissions and maybe a percent 
or two better economy. It probably is also more forgiving of saturated 
injectors' slower opening times since they don't have to fire multiple times 
per combustion cycle. This would also make the ECU's driver circuit slightly 
less complex because current limiting is unecessary.

As far as manifolds, SEFI just needs a port injection style or some way to 
inject the fuel for one cylinder at a time(no Chevy-style TBI).
