Kia Cee’d 1.6 CRDi Stage 1 (136PS / 6-speed manual) - Reviews | EDC17_C57

Enhancements to turbo boost dynamics and fuel delivery maps deliver a more engaging and responsive drive throughout the rev range. With this Stage 1 remap, the 1.6 CRDi’s turbocharger curve is reshaped for quicker spool-up and sustained mid-range pull, while rail pressure and injection quantity tables are fine-tuned to reduce smoke and improve combustion stability. EGR flow calibration has been optimised to maintain clean regeneration cycles without sacrificing performance, and DPF monitoring routines are retained to prevent unwanted fault codes. Torque and load limiters have been raised safely within OEM tolerances to capitalise on the engine’s full 136 PS potential, translating into smoother overtakes and confident hill climbs. Manual gearbox adaptations ensure shift points and clutch engagement match the increased torque output, resulting in crisper, more precise gear changes under load. Throttle mapping has been refined for a natural progression of power delivery, eliminating flat spots during rapid throttle transitions. Diagnostic and emission-control functions remain fully operational to preserve serviceability and maintain compatibility with standard dealer tools. Ideal for daily commuters and light-load hauling, this calibration balances fuel economy improvements with substantial performance gains, transforming the Cee’d into a more dynamic yet reliable vehicle for both urban and motorway driving.
