This ECU will only fit cars with MS43 ECU. Please contact us if unsure.

Once the ECU is installed, we highly recommend you to reset all the adaptations to ensure a proper operation of your engine.

[1] Timered crackle map is programmed to give out 2-4 pops after releasing the throttle, followed by silence and fuel cut for economy.
[2] Under normal conditions and no air/vacuum leaks, the idle will barely be affected. Please ensure you have no airleaks when carrying out ICV delete. Blanking plugs are included free of charge.
[3] The all new feature for MANUAL cars with NO CATALYTIC CONVERTERS. Cuts ignition at 4000rpm with the clutch in. Clutch switch must be fully functioning. May also be used as no-lift shift (NLS).
