E30 E30 — Stage 1 ECU Tune
- 27% increase in peak power output to 150kW
- 25% increase in torque delivery to 203Nm
- Optimised fuel system for enhanced atomisation
- Improved boost control via solenoid management
- Drive-by-wire integration for responsive throttle response
- ECU calibration for maximised combustion efficiency
This 1989 E30 runs a full Motec M130 setup managing an S50 conversion fitted with Schrick 284/296 camshafts and individual throttle bodies. The carbon-enclosed intake and 3-2-1 headers provide good flow to match the cam profile, while upgraded injectors and a high-pressure fuel pump keep up with demand on 98 RON.
The calibration was built to suit the broader cam duration and throttle response from the ITBs. Result was 150 kW at the wheels with 203 Nm, measured by the workshop. The Motec platform gives full control over ignition and fuel maps, which is essential when you're working with aggressive cam timing and individual throttles that need fine idle and transient calibration.
Intended for closed-circuit competition use where the top-end focus and sharper throttle make sense. Not a street-friendly setup given the cam spec.
Why the relatively modest torque figure with those camshafts?
The Schrick 284/296 cams are quite aggressive and shift the torque curve higher up the rev range. You sacrifice low-down grunt for top-end flow, which suits circuit work but won't deliver big torque numbers at the wheels on a naturally aspirated engine.
Does the Motec M130 handle the individual throttle bodies well?
Yes, the M130 has dedicated support for ITB setups including per-cylinder fuel and ignition trim. Calibration takes longer than a single throttle body, but the result is much sharper response and better cylinder-to-cylinder control.
Is this a daily-driver tune?
No. The cam duration and ITB setup make it lumpy at idle and peaky in the powerband. It's calibrated for competition use on closed circuits where you're holding higher rpm.
