[Diy_efi] batch or not to batch...

[Frey, Richard K]

For maximum efficiency and lowest pollution, sequential firing is a
plus.  Otherwise, batch fire is just fine.  Sequential injection allows
slightly, very slightly, better idle, efficiency, and emissions at low
rpms.  At any kind of power requirement, your injector duty cycle will
be 80 - 90% which means they're open nearly all of the time, so batch
firing is about the same as sequential at that point.  Individual
injectors per cylinder is a must, but batch firing is, although not the
best, just fine.

My opinion,

Hi guys...

Just wondered if anyones done tests to see the pros and cons of batch or

non-batch firing injectors. obviously it'll depend somewhat on the 
manifolds in use, but it'd be good to know more details.
