Keep in mind that these papers might not provide the exact pinout you're looking for, but they may offer valuable insights into the 17C61 microcontroller and ECU design. It's important to distinguish between different types of
| Vehicle | Engine | Key Pin Differences | |---------|--------|----------------------| | Fiat Punto 1.2 8V (188) | 176B2000 | A18 crank sensor uses 3-wire Hall; pin B23 = tacho output | | Fiat Brava 1.6 16V (182) | 182A6000 | Additional injector drivers? No – still 4 (A3–A6). Uses both lambdas (B16, C5) | | Lancia Ypsilon 1.4 8V | 350A1000 | Pin B8 runs fan relay via external PWM (different from Punto) | | Alfa Romeo 147 1.6 TS | 182B6000 | Pin A17 knock sensor is sensitive – double shielded required | Uses both lambdas (B16, C5) | | Lancia Ypsilon 1
