Fuel Injection Recommendations
So, if someone was going to convert to fuel injection on a 440 in a Demon, what system would you recommend and why? No power adders, just a fun, hot street car.
*** Edit
I am meaning to compare fuel injection setups, not a comparison of carb vs EFI
I run a MegaSquirt MS3 Pro MPFI.
The ECU was new in 2016, so MS has newer stuff available. I can say this in 5 years of use the ECU has been bulletproof. I run a ported GM Throttle Body using a shop built adapter and all GM sensors, cheap, available anywhere and also reliable.
The Tuner Studio platform for tuning and and viewing the fuel and ignition settings is straightforward and easy to use. I have a laptop that I keep in the car to tune with.
Some of the built in controls beyond fuel and ignition with the MS3 Pro are: launch control with either fuel or ignition cut or a combo of both, traction control, electric radiator fan control, data logging, ability to have trim control over each injector independently, knock sensor, can run multiple EGO sensors, data logging.
And more. There is an active community support forum as well as information videos on you tube.
MS is not for everyone as even though you can buy a built ECU and a complete wire harness, the rest of the hardware: injectors, sensors, fuel system, ignition system is all sourced by you. So you have to make decisions on what fits your build. I was good with that as I had experience on those components, and built exactly what I wanted.
If you want a FI system that is one stop shopping and you get it all in one big box, MS is not for you.
If you want to build a fuel injection system that has a deep reservoir of user defined controls, has the hard ware components chosen by you and has a very high level of sophistication in functionality and adaptability. MS is for you.
