What year Omni and what year engine? Do you have the electronics to go with the engine? The LogicModules can be programmed by socketing, the SMECs can be modified for external programming see D_CAL and Mopar C_hEM on Yahoo groups. If you are buiding it from scratch, the 87 Daytona electronics are supposed to be the best 2 piece and 89 T2 SMEC the best 1 piece setups. If I can help, be it long distance, let me know.
