He Tunes 1970s Classic Cars with a Laptop (and they're fast)

What started as a personal project to solve his own "car headaches" has grown into a specialized business that breathes new life into vintage Mercedes-Benz, Volvos, and even Alfa Romeos. In this episode of Gearhaus, Kalasinga and Vanilla go out to meet Peter Mbiria, the mastermind behind Voltarent ECU, who is revolutionizing how we maintain and performance-tune classic vehicles. Peter’s story is one of pure innovation. Born out of the frustration of dealing with unreliable mechanical fuel systems on his own 190E, he decided to build his own standalone ECU from scratch. Now, he narrates his technical journey of moving from basic 8-bit controllers to high-performance processors capable of managing everything from fuel delivery to complex ignition timing in real-time. Watch this episode and learn how: Peter replaces the notoriously finicky Bosch K-Jetronic "spider" systems with modern, programmable EFI. A look at Peter’s custom firmware that uses real-time mathematical formulas instead of traditional lookup tables. A walk-through of a converted 450 SLC and the story of the 190E that outran the competition after its digital transformation. Peter shows off his custom 3D-printed intake adapters and a sneak peek at his experimental air suspension research. Peter is truly an incredible talent in Kenya who proves that with enough R&D, you can make a 1970s classic as reliable and fast as a modern machine.
