Fuel booster plug – Royal Enfield Himalayan


Do you find your bike prone to stalling at low engine speeds, lack of throttle response and a lumpy feel to your motor?

Have you fitted a free flow exhaust and worried about it running too lean?

Then this plug and play device will resolve these problems without the need to re-map you ECU.

Fits the Royal Enfield Himalayan ONLY.

Modern EFI bikes especially Euro 4 run very lean in open loop mode and this can cause stalling, poor running and hesitant acceleration.

This fuelling device interrupts the signal from the air temp sensor and modifies it to make the ECU add approx 4-6% more fuel during acceleration in open loop mode, it will not affect MPG as it has no effect in closed loop mode ie. cruising mode or steady running. The device has its own temp sensor and it modifies the signal to release the correct amount of fuel for the measured air temperature.

Will NOT work with Euro 5 models as they have anti-tamper built into the ECU, please do NOT try to fit to Euro 5.

Himalayan Fuel Booster Plug

Good service from TEC. The booster arrived promptly after ordering. Fitting was not that easy, due to the location of the air temp sensor and surrounding wiring loom. Lifting the rear of the fuel tank, the air filter side panel and moving some of the wiring loom out of the way helped. I put the new air temp sensor inside the DNA air filter. It seems happy in there. The bike runs fine with the new gizmo. It's more enthusiatic about moving off now.

The difference between dry or buttered toast, ...overall a more contented engine.

Himmie booster plug

All my research showed the booster plug for the Himmie (and indeed many other Efi bikes) is the way to go for removing weak fueling built in to achieve emission regs. Having used TEC before and experienced the excellent knowledge and backup when fitting their Tec cam I had no hesitation in fitting their booster plug which done just what was promised.
I look forward now to their promised header/front pipe to complete my improvement program for what is a great little bike.
