First, Who makes chips for 4k's?

The ecu is the brain of how the car runs. It takes info in from various sensors, decides what to do, and adjusts outputs accordingly to keep the car running its best.

While a newer car has much finer control over how the engine operates, and can control many other things, the 4k's are limited. It controls timing, the fuel mixture, and idle to a small amount.
