Common questions

Can a GM Gen IV ECM be used on a 2005 Corvette?

Can a GM Gen IV ECM be used on a 2005 Corvette?

Without reprogramming the ECM with GM’s TIS2Web, the GTO pedal assembly would not be compatible with the 2005 Corvette ECM calibration. Gen IV ECMs can only be used with engines equipped with a 58x crankshaft reluctor. EFILive offers free custom operating system (OS) upgrades for features such as nitrous control and 3-bar forced induction support.

What kind of software do I need for GM LS2 ECM?

If, for example, you are working with an LS2 engine pulled from a 2005 Pontiac GTO and source an ECM from a 2005 Corvette, the ECM must first be reprogrammed with GM’s TIS2Web software using a 2005 GTO VIN. This replaces all calibration segments and turns the ECM into a 2005 GTO ECM.

Why do I need to Reset my ECM?

If your check engine light comes on then chances are there may be an internal electrical issue within your vehicle that must be addressed. Before replacing any parts you want to reset your ECM to ensure that part replacements are absolutely necessary. There are a few ways to reset your Engine control modules.

What happens to the crank sensor on a GMC?

The crankshaft sensor on GMC vehicles is synced to the powertrain control module, or PCM. When the crank sensor is replaced, it must be resynced to the PCM. Without resyncing, the PCM cannot properly determine the position of the crankshaft.

When do I need to reprogram my Chevy PCM?

If the vehicle isn’t performing the way it should, the PCM can be reprogrammed to increase performance. Recalls are another reason your PCM may need to be reprogrammed. Since Chevrolet is a subsidiary of General Motors (GM), GM tools and software are used to reprogram a Chevrolet PCM.

How does the PCM monitor the car’s performance?

Performance Monitoring – Using many different sensors, including temperature, oil and fluid level, air intake, emission level, camshaft angle, or throttle position, the PCM can monitor the car’s performance. When the PCM can’t restore these to ideal levels, it will notify the car owner with the check engine light.
