So when i started on Our 89 civic hatch si it had original ecu with a y8 under the hood it ran right some times... so we drove it from time to time than the cam locked up and snapped the belt so we bought a brand new head and what the think was the correct ecu than it sat for a year we come back to finish it and someone broke in and stole the ecu and the entire msd system that ran the vtec . Got pissed left it for a few years and now we're back to it and need to know which ecu to get again ..still an obd1 vehicle any help greatly appreciated
