The only thing I will be changing in the install will be getting rid of the stock ugly, heavy, huge inlet manifold and replacing it with a home made individual runners linked to one plenum chamber. I'm pretty sure the Mazda k series V6 ecus use sequential. These cars use the same size injectors as their batch equivalents.
Yea around the early 90's allot of manufacturers went to sequential, as Tom says it only has advantages in the low RPM range, idle, cruise etc for response and more efficient burn. This in turn also increases the cost of the system.

Because the system is more complicated it is very difficult to install and most drivers will require professional installation. The electronic control is more complicated and requires additional equipment to run properly. Sequential systems are also more expensive because they require an additional wiring harness that is used to ensure that the injectors pulse sequentially. A V6 engine will need 6 injectors and a V8 would need 8 injectors.
This is very important where vehicles are being produced to meet stricter emissions.īecause there is a single injector for each cylinder, the larger the engine the more expensive the system. Because fuel is used more economically, the emissions released are lower. The throttle response is immediate, which allows for very rapid changes in the fuel to air mixture. Because the fuel is altered for each cylinder, you can potentially get the best performance out of the engine that is possible. This type of injection also produces much lower emissions and provides even better fuel economy. For systems that do not use sequential fuel injection it will be necessary for the entire engine to complete a revolution before the fuel to air ratio can be altered. More or less fuel can be released when the next intake valve opens.

The main advantage of a sequential system is that the entire system has a fast response time when the driver makes a quick change. While sequential variable fuel injection has many benefits, direct injection is quickly becoming the system of choice and is replacing the SEFI systems. Other multi-port systems will fire all the injectors in groups no matter if the cylinder is ready or not.
So in essence, the individual injectors work by themselves because they are fired individually. Sequential fuel injection is a type of multi-port fuel injection system in which each injection valve will open just before the cylinder intake valve opens. Is this bullshit? What's the deal- in fact in laymans terms can someone (Zac?.kpr.?.dave?.) explain sequential and it's benefits.Įdit: actually, it goes weird near the end so I'll just post the good bits. You also need crank and cam angle sensors on the V6 " "That's right, it won't handle sequential, but in reality sequential has no performance or economy advantages, it's mainly for emissions. 'Im i right that this wont manage full sequential injection on v6? If not then how much for ms3 with ms3x? In built up or self assembly. So i asked on a trademe listing for MS and asked about sequential. If I do go MS then I have to decide if I want sequential injection or not as this dictates which Ecu I should go for ie $ or $$$įrom what I have read sequential is all good- allowing finer tuning and better economy plus possible extra power? I don't know.I am still learning!! I might try to keep the stock Ecu for now but eventually will go aftermarket- possibly have a crack at building a megasquirt (MS) The engine I am looking at has as standard sequential injection.
