Expert Insight: Why VIN Programming is Critical
On these late-90s GM trucks and vans, the PCM is more than just an engine controllerโit’s the central command center. It manages everything from fuel injector pulse width and spark timing to transmission shift points and anti-lock brake functions. Without precise VIN-specific programming, your vehicle may not start, the transmission can shift dangerously, or you could fail an emissions test. We handle this critical step for you, using the same tools as the dealership to ensure every parameter matches your vehicle’s original configuration perfectly.
