Sequential VS Batch fire systems

[Mark Pitts]

Well for a start, if you have ONE cylinder that wants to 'pink' you can =
change the timing, and how much fuel you throw into one cylinder, and =
keep all the others at 'normal'.....

Just a thought

All the applications that Robert J. Harris quoted in his original post  =
were
high-speed, high power applications, and sequential fuelling is  not =
going to
give you anything here.  What sequential injection does give is better =
low
speed, part load combustion stability leading to better real-world =
driveability.

Would anyone like to comment on batch fire vs sequential injection =
systems?=20
What are the real world advantages to each under specific circumstances? =
 GM
went to sequential systems recently on the new camaros and corvettes, =
WHY?  Is
anything really gained with a sequential system in terms of performance,
efficiency or driveablility?
