got the car running on the ls1 computer today... i repinned the lt1 harness into the connectors and addded the in the coil wires and made a custom wheel for the opti.
i was worried at first as it would barely stay running then i pulgged in the other coil harness and it runs like a champ now..
dont mind the smoke there was some antifreeze on the downpipes.
