Build it. Tune it. Break it.
A puzzle game where you assemble real engines in the order a real engine goes together. A simulator where you can lean it out, over-advance it and watch what that costs. And when you are ready for the real thing, a remote tune for your stock car, written from your own ECU file.
The demo
Six engines, five controls, a dyno that shows you against stock. Every pull explains itself in plain English. It is educational — it will not tune your car, but it will show you why a tuner does what a tuner does.
Three things, one shop
More than 200 real engines, from a lawnmower single to a locomotive V16, each assembled in the order it really goes together. No decoys, no guessing which bolt: the puzzle is the sequence, and the game teaches it.

Where the boost in a Stage 1 comes from on an EA888 Gen3, how the ECU controls the wastegate, and why the same turbo can safely give more than the factory asked.
A tune is checked against a log, not a feeling. Which channels to record on an EA888 Gen3, how to do the pull, and what the tuner is looking for in each column.
The EA888 Gen3 came in several outputs across the GTI, Golf R, A3, S3 and TT. How to read the engine code and the ECU part number on your own car, and what each tells a tuner.
An engine-assembly puzzle game, a tune simulator you can break, and a remote ECU tuning service for stock cars.
