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.

Great service, great communication, great product, can't wait for the new cam shaft to become available!

Easy to fit but make sure you reconnect the fuel pump connector (if removed) before switching on

Good Quality and easy to fit, if a bit fiddly. I disconnected the fuel pump connector to lift the tank a few inches but forgot to reconnect before switching on. Now I have 'check engine' light on. ECU has logged the fault and I guess needs to be reset somehow. I have a 2020 bike with a 3 wire service connector. Also fitted the DNA filter & will be fitting the Lextek silencer shortly.


I have a Himalayan with a Lextek exhaust end-can and free-flow air filter fitted. The fuel booster plug makes a real difference; the banging and popping on the over-run and cutting out in traffic has all but gone. For me, the fueling seams cleaner and crisper. All in, a great purchase.
