Lingenfelter Introduces CAN Bus Converter for Late-Model GM Engines


Lingenfelter Performance Engineering (LPE) has been at the forefront of small-block Chevy tuning for decades, and it isn’t because they weren’t innovators or  individuals who played it safe in terms of conventionalism. When the crew isn’t building engines, modifying customer cars or racing their own, they’re developing new software and components for enthusiasts who prefer to wrench on their own projects.

Such is the case with this interesting and revolutionary CAN Bus converter designed specifically for those enthusiasts loping to bring their older vehicle up to modern standards with an LS-series engine swap. We could break it down further for you, but luckily, we’re fortunate enough to let LPE do that for us in their official press releases below!

Lingenfelter Introduces Revolutionary CAN Bus Converter
for Late-Model GM Engines

BRIGHTON, Mich. – Lingenfelter Performance Engineering is offering a CAN Bus converter to simplify late-model GM engine transplants into older cars. Given the popularity of late-model GM engine swaps and the abundance of aftermarket support for these affordable performance engines, the Lingenfelter Performance CAN Bus converter could be a barrier-removing technology, paving the way for even more GM ECU-controlled LS engine transplants.

“Our CAN Bus signal converter allows builders to use traditional high-performance gauges when installing a late-model, GM ECU-controlled LS engine into older cars,” says Mike Copeland, vice president and general manager, Lingenfelter Performance Engineering. “This new converter will greatly simplify the installation and allow the owner and tuner to take advantage of the technology in today’s on-board computers,” adds Copeland. “It’s ideal for anyone doing a late-model GM engine swap into an earlier model car, or for a late-model owner who wants to install additional aftermarket gauges.”

“What is CAN Bus?”

CAN stands for Computer Area Network and a vehicle’s CAN Bus is a message-based protocol designed specifically for automotive applications. The CAN Bus is a vehicle-based network that allows controllers and devices to communicate with each other within a vehicle.

Lingenfelter’s new converter reads the CAN Bus data and converts the digital signal into an analog output to operate traditional performance gauges. “It’s a very simple hook-up and does not require replacing any of the factory-supplied sensors,” Copeland said.

The Lingenfelter CAN Bus converter provides gauge output for multiple different parameters, such as water temperature, boost level, engine rpm and fuel pressure. However, the Lingenfelter CAN Bus converter can be configured to read any data on the communication bus such as oil pressure, oil temperature, water temperature, tach, speedo, and boost. It is infinitely adjustable and can be configured for any aftermarket gauge, regardless of the brand.

Currently, the Lingenfelter CAN Bus converter is only available for GM ECUs, but Copeland points out they have the capability to read other manufacturers’ ECUs via upgradable software that will be announced at a future date.

Lingenfelter Performance Engineering will program the CAN Bus converter specifically for the outputs each customer desires. The Lingenfelter CAN Bus converter is currently available for order and output customization.
