i20 NLine 1.0L TGDi - Wolf Stage 2 Dyno run
22% gains in horsepower over stock
@ WolfPerformance
Stock dyno run
119BHP & 200NM
Wolf Custom Tune:
145BHP & 268NM
Happy with the power and torque numbers.
Good numbers and very happy with the progress
Wolf Stage 2 dyno run puts out 145 hp / 268 nm at crank.
Base run of standard i20 NLine puts out 119 hp / 200 nm.
We have continued our development work on the Hyundai i20 NLine 1.0L TGDi platform. We started with our present state of tune. Lots more effort was spent on the ECU calibration, in order to optimize the performance, by working on this DI (TGDi) engines thermal dependencies with respect to other tuning variables. Based on the previous logs and dyno runs, we started with calibration considering vehicle's specific pain points, while also maintaining safety features to ensure reliability. We also noticed that on extended power runs some cars are more sensitive and see temps spike which is higher than what it should be. Hence, we have revised the tune to change boost levels vis-a-vis intake and exhaust temps which should definitely helps to keep things safe.
Our revised torque modelling strategy is more PID sensitive which helps to effectively control turbo wastegate under high boost conditions and this inturn helps to hold steady boost without unwanted boost spikes. AFR calibration on the high octane tune is kept relatively conservative at peak loads and fairly closer to stock tune through most of the rpm range at low loads. In low load and cruising areas AFRs are at near stoich levels with enrichment kicking in based on revised calibration for torque request vis-a-vis load, RPM and vital temperatures.
Air flow parameters including peak boost and intake temps have close correlation to fuel octane rating , AFRs and ignition timing and hence our calibration keeps a fine balance between them while also managing heat effectively. Our calibrators also ensure that knock sensitivity index is kept at OEM levels to keep the engine safe. Rather than try to showcase the absolute max power, we strive for safe calibration that will provide a reliable tune while making
