Hi All

Latest Job:
Jaguar XJ12 JX5.3C

Setup and wire up full sequential EFI System.

Car had a M4 Motec running 4 groups of 3 injectors.
The cars wiring had all been replaced with the exception of the engine management loom.
I set it up with a Motec M800 with a 12 cylinder upgrade so it can run 12 injectors sequentially.
I added a sync sensor as the standard setup only runs 1 ref sensor in the distributor.

Made up a box to fit all the electronics, relays, fuses, and ECU.
Made up a fully removable loom to suit.

Loom has prevision for 2 O2 sensors so in the future we can setup closed loop mixture control that can trim each 6 cylinder bank individually.
All went well and car drives nicely.
