The MegaSquirt III system with the MS3X Expansion board or MS3-Pro will do full 8 cylinder sequential fuel and ignition. If you want to know where sequential fuel injection systems really shine in getting the MOST out of a motor, read on! But for a race car, many would say you’re splitting hairs a bit there. Worth noting though, the sequential fuel injection system did fire up a bit smoother/easier, and run a bit more smoothly at idle and at light throttle angles. Peak power was more or less the same so long as we did not employ individual cylinder tuning on the sequential injection system. We’ve dyno tested several cars with using batch fire and sequential injection on the same motor. You might enjoy that entire series actually! Read Chapter 4 in the EFI Tuners Guide for more information on the benefits of sequential versus batch fuel injection. It’s a fact that at higher engine speeds you won’t have enough time to spray all fuel while the valve is open, making this somewhat pointless, particularly for a performance oriented application.Īt these higher engine speeds 99% of sequential systems (exceptions being race only systems with super massive injectors) cannot spray all of the fuel needed while the valve is open anyways, and sprays it both while the valve is opened and closed, very much like a batch system such as the MegaSquirt I and II. Batch Fuel Injectionīatch injection (which is what the MegaSquirt-I and and most MegaSquirt-II versions do) does not attempt to spray only when the valve is open. Benefits can be seen in emissions, drivability, and fuel economy particularly at these low engine speeds and loads. Sequential fuel injection attempts to only spray fuel while the intake valve is open for the cylinder that is about to fire, which in most cases is only possible at low engine speeds between idle and low speed cruising.
