- Engine stalling or misfiring.
- Engine performance issues.
- Car not starting.
Why would a car’s computer need to be reprogrammed?
Flashing or reprogramming a car’s computer is one way to keep the vehicle’s engine control modules up to date. Cars tend to run better and more efficiently when their programming is optimized. Reprograming the computer can also maximize power output, for those who are looking to get more performance from their engine.
What does an ECU flash do?
ECU Flashing is the process of updating the software that runs on your bikes ECU. This allows you to change various maps and settings in your ECU and significantly improve the performance of your engine.

The least invasive way to diagnose your ECM is to connect an onboard diagnostic (OBD or OBD II) tool to the diagnostic port. From there, you can scan to see if your engine computers have produced any error codes. There are many of these codes, and your diagnostic tool’s manual should have information on what they mean.

Can I drive with a bad PCM?
Bad PCM shouldn’t be a cause for worry, though, and many states allow drivers to pass checks despite the engine light is on. Nonetheless, the sooner you fix it, the better your engine will perform and you can also protect other parts and systems that could get compromised.
Can a PCM be repaired?
Typically, PCMs are not rebuilt in the same way that alternators and water pumps because there are no mechanical parts that wear out. Remanufacturing a PCM generally means testing the computer, isolating and repairing any faults that may be found, then retesting the computer to make sure everything works correctly.
Will disconnecting battery reset car computer?
Does Disconnecting Battery Reset Check Engine Light? Yes, disconnecting the engine is one method of resetting your check engine light.

Allow your vehicle to idle for at least 10 minutes to allow your ECM to “learn” any new modifications you have mounted. Since the auto ECU is such a sensitive module, it is critical to reset it after making modifications, or the new modifications which interfere with how the engine previously worked.
What does resetting car ECU do?
“Resetting the ECU” is the process of clearing all the long term memory from the ECU’s memory. These variables trim idle speed, fuel, spark, and more. The ECU will also store trouble codes for diagnostic capability.
