- HP Tuners has unlocked the engine control module of the Chevrolet Corvette ZR1.
- A ZR1 with this tune made 1,180 horsepower and 1,094 pound-feet of torque at the rear wheels.
- The ECU upgrade is available starting at $1,499.
HP Tuners has unlocked the engine control module (ECM) of the Chevrolet Corvette ZR1. Despite General Motors trying to prevent tuning with new cybersecurity measures, the aftermarket company has launched an upgrade for the model that can deliver almost 1,200 horsepower to the rear wheels.
A standard ZR1 produces 1,064 hp and 828 lb-ft of torque from the twin-turbocharged 5.5-liter flat-plane crank V8 engine. The ECU upgrade, which costs $1,499creates 1,180 hp and 1,094 lb-ft of torque while maintaining the car’s original factory thermal and component limitations.
Matt Sanford of HP Tuners posted on Facebook that greater power gains are possible if you ignore stock safety parameters. He said the ZR1 could achieve up to 25 percent power gains with racing fuel.
He also highlighted the challenges of tuning the Bosch-supplied ECM, which he wrote is “not the same as tuning any other GM product.” You can see his full post below, where he explains the technical details of the tune.
