6 MPS — Stage 3 ECU Tune
- 47% increase in power output
- 23% increase in torque delivery
- Improved power response
- Improved torque characteristics
- Enhanced boost control via wastegate solenoid
- Optimized fuel injection parameters
This 2006 MPS runs a fully built bottom end with forged rods and pistons, ARP head studs, and a larger turbo—all calibrated for closed-circuit competition use on 98 RON. The factory ECU was reprogrammed to manage the new hardware: uprated fuel pump, front-mount intercooler, improved airbox, and that bigger snail.
Dyno results came back at 151 kW and 322 Nm at the wheels, up from 103 kW and 262 Nm respectively. That's a 48 kW gain while keeping fuelling and timing sensible for pump premium. The MZR-DISI responds well to boost when the internals are sorted, and this file balances output with durability.
Focus was on driveability under load and thermal stability during extended sessions. No corners cut on the fuelling map—critical when you're asking this much from a platform that tends to run lean under sustained high load.
Why factory ECU on a Stage 3 build?
The factory ECU has enough headroom when properly calibrated, and it keeps the car's OEM functionality intact. For this spec and power level, a standalone wasn't necessary.
Is 98 RON enough for 151 kW at the wheels?
Yes, with the right timing and fuelling strategy. The forged internals and larger turbo allow safe compression and boost levels on pump premium without needing E85 or race fuel.
What's the key risk area on these MZR-DISI builds?
Fuel delivery under sustained load. The factory system leans out quickly when pushed hard, so the high-pressure pump upgrade and careful fuel map validation are non-negotiable.
