Denso is Toyota's in-house ECU supplier (a locked platform). Toyota's petrol range spans naturally aspirated Dynamic Force engines and turbo units for the GR series.
The GR models (Yaris GR, Supra) have a growing tuning culture. Toyota has an active JDM tuning community (GR Supra, GR Yaris, GR86). The Denso ECU is a locked Toyota platform, and most models do not respond to standard chip tuning. High-output Toyota GR models sit in the performance segment with solid Stage 1 headroom.
