The advance curve on the standard Lucas distributor is nowhere near what the engine needs. I'm looking at replacing the amplifier with a programmable module to remap the ignition and do away with the standard advance system but I'm stuck on where to get the tacho pulse for the old Lucas L EFI ECU. It currently comes from the existing amplifier and I'm tempted to just hook it up to the negative terminal on the coil but I don't want to blow up my ECU by sending it a signal that's too high. Do you have any experience fitting the Bosch module to an old Lucas L EFI system?
