The device replaces the stock narrowband lambda (O2) sensor connector, correcting excessively lean factory fuel maps that cause engine hesitation, rough running, and excessive exhaust system heat.\u003c\/p\u003e\n\u003cp data-start=\"664\" data-end=\"980\"\u003eThanks to the use of a dongle, the ECU receives a stable, optimized signal, which translates into a smoother response to gas, better engine flexibility and significantly more pleasant operating characteristics in the lower and mid-range of revs - especially noticeable in city, touring and off-road driving.\u003c\/p\u003e\n\u003cstrong data-end=\"331\" data-start=\"296\"\u003e\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHow it works:\u003c\/strong\u003e Stock ECUs in many KTM \/ Husqvarna \/ GasGas models operate in the low RPM range with a very lean mixture (around AFR 14.7), resulting in jerking, poor throttle response, and increased exhaust manifold temperatures. ThunderDongle emulates the lambda sensor signal, maintaining the mixture at a safer, more optimal level, improving engine refinement without interfering with ECU maps.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eBenefits:\u003c\/strong\u003e Smoother throttle response, reduced jerking at low revs, improved engine flexibility, better engine performance, lower exhaust system operating temperatures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003ePlug \u0026amp; Play Installation:\u003c\/strong\u003e The device mounts directly in place of the stock O2 sensor plug.
