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.

2019 RE Himalayan booster

Before fitting fuel booster - 2000rpm tickover, stalled immediately after cold start up, 1st gear lurching at low rom.
After fitting fuel booster - tickover 1400rpm, no stalling, no lurching
Money well spent.

Goes like it should.

As soon as you start the bike after fitting, you can tell the difference straight away. All that lumpiness has disappeared and it ticks over smoothly. Not quite as easy to fit as I expected. I couldn't locate the sensor plug from the drawing as it was behind the wiring loom. So I took out the air filter and located the probe of the original sensor right up in the top left hand corner of the air box, just under the frame and worked backwards. I took out the two tank bolts and raised the back edge of the tank and then was able to plug in the new sensor. Great improvement. Thanks Biketec.

Transformed the bike

No exaggeration, this piece of kit has transformed the whole feel of the bike when cold. It will now happily idle on the stand to warm up, instead of stalling and needing the throttle holding open or blipping. It no longer cuts out when slowing or stationary, and it makes the acceleration much smoother by removing the snatchiness. It saves prodding the starter several times which must help the battery, and gives me more confidence when using clutch, brake, throttle, indicators etc such as at T-junctions. Wish I'd fitted one years ago!
Excellent service from TEC as always, arrived in a couple of days, well packed, complete with instructions etc.
