swaping an EFI in a carbed 110

Anyone successfully swapped a range rover or disco v8 EFI into a older V8 110 ? what is the best computer to use , what other inputs are needed to make it run right ( o2 sensors , Mass air flow ....? what is the simplest (least complex ) set up to EFI a 4.6 into an 1985 110 ? any and all feed back of successful installs would be appreciated.

I did it on a 3.5 90. Used a complete system from a 3.9l RRC. You need to use all of the sensors that come with it. They are all connected to the manifold/intake other than the VSS and O2 sensors. Make sure to add a vehicle speed sensor as it affects the idle control and you will have stalling problems without it in place. Get the O2 sensors as close to the engine as possible after the pipes come together.

I mounted the intake on backwards with the air cleaner against the bulkhead. This allowed the intake to clear everything.

For a 4.6, you would probably want a custom tune. On my install on the 3.5, it is running a bit rich.

There is one on ECR's website. I would copy that. Basically you fit NAS 110 fuel system (lines, tank, pump, evap you would need to figure out -- use disco/d90/RRC) and a 14CUX system with all sensors. I have not done it, but I have taken apart two NAS 110s, am building a NAS 110, and had a carbed V8 110.
