What Stage 1 is

Stage 1 (also called a Stage 1 remap or Stage 1 software) is an optimisation of the software in the engine control unit, with no hardware changes. The turbo, injectors, exhaust and intercooler stay stock.

The calibration works on the engine control strategies: torque request and management, internal limiters, boost pressure, injection quantity and timing, ignition timing and throttle response. Everything is adjusted within the safety margins of the original components, so the engine uses the reserve left in it at the factory.

General ranges. The exact figure for your engine is in the calculator: an average value from repeated dyno measurements. On all-wheel drive we only measure Haldex systems on the dyno (VW, Skoda, Seat and Cupra with a transverse engine, Audi A3 and TT), with the rear axle disengaged; on the others (for example Audi quattro on other models, BMW xDrive, Mercedes 4MATIC) we work with road logs.

How much Stage 1 costs

Stage 1 starts from 1,499 RON. For half of the engines in the catalogue the price is between 1,499 RON and 1,799 RON. The price is final: diagnostics and the dyno measurement before and after are included.

The price varies between cars because of the ECU (some are read through OBD, others have to be removed and read on the bench or unlocked), the complexity of the engine (bi-turbo, hybrid) and the calibration time on the dyno.

With automatic gearbox (TCU) tuning in the COMBO package, the gearbox costs less. All prices, including the gearbox, Eco tuning and the dyno test: the chiptuning price guide. Gearbox on its own: from 1,499 RON.

Stage 1 frequently asked questions

What does Stage 1 mean?
Stage 1 is a software optimisation of the engine control unit (ECU) on completely original hardware. The calibration adjusts boost pressure, injection quantity and timing, torque limiters and throttle response within the safety margins of the stock components. No parts are changed.
How much horsepower does Stage 1 add?
On turbo diesel engines 25-35%, on turbo petrol engines 20-30%, on naturally aspirated engines 5-12%. The figure for each engine is in the calculator above, an average value from repeated dyno measurements.
How much does Stage 1 cost?
At AMC Motorsport, Stage 1 starts from 1,499 RON. For half of the engines in the catalogue the price is between 1,499 RON and 1,799 RON. The final price for your engine is shown in the calculator and on the engine page, with diagnostics and the dyno measurement included.
How long does Stage 1 take?
On average 1.5-2 hours, including diagnostics and the dyno measurement before and after. When the ECU has to be read on the bench or unlocked, it can take longer; we tell you when you book.
Can I go back to the original software?
Yes. The original software stays in our archive with no time limit. We write it back free of charge when the car is reprogrammed through the diagnostic port. If the ECU has to be removed or can only be written on the bench or in boot mode, the labour is charged.
Does the car pass the periodic technical inspection (ITP) after Stage 1?
A correctly calibrated Stage 1 keeps emissions within the limits needed to pass the ITP, with the exhaust after-treatment systems fully working. The engine must be in good mechanical condition: an engine with existing problems can fail the emissions test whether it is stock or modified.
What is the difference between Stage 1 and Stage 2?
Stage 1 is software only, on original hardware. Stage 2 is advanced software that needs minimal hardware changes (usually a sports downpipe and an improved intake) and adds another 10-15% over Stage 1.
