Their 600 series ECU seems to have all the functionality needed , it does say TPS or MAP for load though so it will have to be one or the other . Their basic loom seems good value at £60 .Would the injectors still be batch fired , I assume sequential would be for more highly modified engines ?
The injectors would be batch fire unless you install a cam sensor too. That is assuming that the controller you mention suports fully sequential.
Lucas did a tremendous amount of very high quality research, many years ago, into the benifits of having sequential injection over batch fired and the findings seemed to show that there wasn't really anything special to be had from it.
However it has to be said, that research was done before the pressent digital age.
If a combination of fully sequential ignition and fuel injection was adopted, then with some serious maping of the injection and ignition angles it should be possible in theory to make some small gains over batch fired throughout the range. (Possibly..???) ..... The emisions would be improved undoubtedly though.
All the best
