96-97 3100 Tuned Ecm

Custom ECM Tune for 1996–1997 GM 3100 Engines

Unlock the full potential of your 1996–1997 GM 3100 engine with a custom ECM tune designed specifically for race, off-road, and demolition derby applications. This calibration removes factory limitations while optimizing performance and reliability for stripped-down builds.

The tune improves throttle response, fueling accuracy, and engine performance while eliminating unnecessary factory systems that are not needed in race or derby environments.

Features

• Precise timing adjustments

• Optimized fueling tables

• Increased rev limiter

• Modified temperature parameters to allow the engine to run hotter

• Unnecessary sensors eliminated

• Security / VATS removed

Installation Notes

This tuning is compatible with the stock wiring harness, but the following modifications are required for proper operation:

• Install a push-button start

• Hotwire the fuel pump

For the easiest installation and cleanest wiring setup, we recommend pairing this tune with a Simplified Harness designed specifically for 1996–1997 GM 3100 engines.

For demolition derby applications, it is also recommended to hotwire the transmission to prevent unwanted shifting issues during competition.

Important

• Off-road use only

• Not intended for emissions-controlled or street-driven vehicles
