4000 RPM? That's far out, are you building a race car?

There are RPM limiting or governor functions in the Bosch engine management
systems.

From Volvo's ignition manual TP31397-1:

All control units are programmed with some type of speed limiting function.

EZK The ECU uses the power stage to interrupt every other plug. Usually becomes active over 6200 RPM.

On Bendix systems the ECU normally commands the power stage to reduce the ignition coil charging period, producing a weaker spark, which reduces the engines output.

Aging ECUs are likely to act up without robust filter caps, that can crap out
with old age. The ECUs must be protected from the high radio noise / RFI from the ignition.
