I have just installed a fuel injection and electronic ignition system supplied by Emerald on my 4,2 Etype Series 2 2+2 1970. The system used the Mangoletsi direct head port injection manifold, K6 ECU, trigger wheel and pick up, 6 way coil pack, Lambna sensor etc, etc. Before I undertook the installation I looked on line for any videos of other Jag enthusiasts that had done this to their car but could not find any so I videoed most of the installation. The video is in two parts and can be viewed on youtube. If anyone wants any more information on the installation happy to answer any queries via this forum.
Hopefully the restoration of the interior will be completed in the next few months so I can MOT the car, then get it on a rolling road for mapping.
