TSP TPI/Carby Map Switch – Suits KTM/Husqvarna/GasGas TPI & 250/300 Carby Models 2008-2023

Handlebar-mounted map switch from Two Stroke Performance (part number P.OTH.SWITCH.TPI) that lets you change engine map on-the-fly with a blue toggle. An affordable alternative to the genuine KTM/Husqvarna map switch.

It plugs straight into the white factory connectors that sit against the frame under the fuel tank — no cutting, no splicing. Every bike on the list below leaves the factory with those plugs, and every stock ECU/ignition already carries two tunes, so the switch works whether your bike is stock or tuned by TSP.

Useful the moment conditions change: flip to the soft/safer map for deep sand, mud, roots or slick rocks, and back to the aggressive map when the ground hooks up again.

Fitment

• KTM / Husqvarna / GasGas 150, 250 and 300 TPI — all model years
• KTM / Husqvarna 250 / 300 carburettor models, 2008 onwards
• May also suit 125 / 150 carburettor models that use the same factory plugs

Works with the stock ECU/CDI, with aftermarket ECUs/CDIs and with the TSP ECU Reflash Module (ERM).
