Physically fitting another four cylinders with 4.2L more displacement – all from a different manufacturer – into a small sports car is a monumental mechanical challenge. But keeping the advanced stock controls of the little convertible from complaining about missing components and new inputs feels even more daunting for most automotive enthusiasts. A step that nobody seems to have fully figured out yet – unless you are ready to shell out $3,000 dollars for a complete stand-alone engine management system. Recently, MRS Electronic linked up with Flyin’ Miata to eliminate this conundrum by providing a true 21st century automotive grade solution…for a fraction of that cost.


MRS Electronic no stranger to automotive electronics. In fact they are a well-established international supplier to many off-road, Agricultural, construction, and custom vehicle builders as well as global automotive manufacturers. Their specialty is the design, production and customization of the smallest, smart CAN controllers, CAN gateways, and programmable relays worldwide.  At the new Dayton, Ohio location experts focus on products with wireless Bluetooth/WiFi/GSM communication, telematics, touch screen displays, mobile apps, IoT and turnkey cloud solutions.

The smart, next generation CAN Gateway Module used in engine transplant applications is especially made for custom automotive and aftermarket applications like the one at Flyin’ Miata.


Working with an entirely new car platform, we first acquired data and tested the concept on a stock vehicle that is representative of the target vehicle. The target vehicle is a 2016 Mazda MX-5 Miata beefed up with a General Motors 6.2L LS3 V8 with almost 400 more horsepower compared to the vehicle rolling of the dealer’s floor just a few months earlier. Flyin’ Miata has done this many times before for older MX-5 Miatas, but the technology of the latest 2016 model raised the bar significantly. With push button start and extra CAN networked modules, the cost of rewiring the entire car or developing individual solutions would have been excessive.


Merging the CAN networks of the stock vehicle with the LS3 has been attempted before by many others, who usually apply the technique of spamming the target vehicle’s bus network with messages with the proper data, but it leads to data errors and heavy bus situations. Automotive professionals would rather see a more sound approach and usually cringe whenever they see a solution like this being proposed. Which is why our Smart CAN Gateway includes three CAN transceivers, one for the target PCM, one for the rest of the target CAN network, and one for the new CAN messages from the engine being transplanted. Also, the Smart Gateway hardware can be programmed for any CAN value to be sent based on incoming CAN messages from any of the busses connected. In addition, we can trigger built-in relays, read analog values, process digital I/Os and much more.
