Hyundai i20 1.0 T-GDi Stage 1 Remap

Name: Hyundai i20 1.0 T-GDi Stage 1 Remap
Brand: Hyundai

On Hyundai i20 1.0 T-GDi turbo petrol engines a Stage 1 remap recalibrates the boost pressure, ignition timing, fuelling and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.

How much bhp does Hyundai i20 1.0 T-GDi chip tuning add?

It depends on the generation and the stock output. 1.0 T-GDi engines with 100–120 bhp reach 120–140 bhp with a Stage 1 remap; the largest gain is +40 bhp (1.0 T-GDi 100hp). Pick your version in the table below.

About the Hyundai / Kia 1.0 / 1.6 T-GDI

T-GDI engines are the turbo direct-injection petrols of the Hyundai i20, i30, Kona, Tucson, Elantra and Kia Rio, Ceed, Stonic and Sportage. The 1.0 T-GDI is a three-cylinder of 100–120 hp; the 1.6 T-GDI a four-cylinder of 150–280 hp.

How a Stage 1 remap works on the Hyundai i20 1.0 T-GDi

Stage 1 recalibrates boost, ignition advance and fuelling. The gain spreads across a wide rev range and is clear in the mid-range on the 1.6 T-GDI. On DCT cars the clutch and torque limit are respected.

Pre-remap checklist

Ignition coils, spark plugs and fuel quality.
Carbon build-up on the intake valves.
Boost leaks and wastegate actuator.
Oil level monitoring.

This section is based on GP Power ECU workshop experience; the power and torque figures come from the catalogue measurement above.

Frequently asked questions

How much bhp does Hyundai i20 1.0 T-GDi chip tuning add?

It depends on the generation and the stock output. 1.0 T-GDi engines with 100–120 bhp reach 120–140 bhp with a Stage 1 remap; the largest gain is +40 bhp (1.0 T-GDi 100hp). Pick your version in the table below.

What is the difference between Stage 1 and Stage 2 on the Hyundai i20 1.0 T-GDi?

Stage 1 is software only: no part of the car is changed and the figures in the table apply to this software. Stage 2 is software prepared for hardware changes such as the exhaust, intercooler or intake; the hardware comes first, then the software.

Will chip tuning damage the engine?

No. Values stay inside the safety margin the manufacturer leaves; engine, gearbox and turbo limits are not exceeded. Every file is verified with a road test and data logging. If the car needs maintenance first (worn injectors, blocked filter, weak clutch) we tell you before starting.

Will my fuel consumption go up?

With the same driving style it usually drops, because you hold the same speed at lower revs and less throttle. If you use the extra power, consumption naturally rises. It is down to your right foot.

How long does it take? Do I leave the car?

Most cars take 1–2 hours and you get the car back the same day; no need to leave it. Some models need the ECU removed, which takes longer — we tell you when booking.

Can I go back to stock later?

Yes. The original file is read and archived before any work. We restore the factory software free of charge whenever you ask.

What is checked on the Hyundai i20 1.0 T-GDi before remapping?

Before working on the Hyundai / Kia 1.0 / 1.6 T-GDI we check: Ignition coils, spark plugs and fuel quality. Carbon build-up on the intake valves. Boost leaks and wastegate actuator. Oil level monitoring. If something needs attention, maintenance comes first; the remap is applied to a healthy engine.
