What kind of support does Racext offer for installing chip tuning modules?

CHIP TUNING FOR Keeway Motor Rkf 125 E4

We recommend that you start using the additional module for Keeway Motor Rkf 125 E4 with the knob set to minimum and gradually increase the knob until you find the setting that is best for your bike. Slightly modified bikes (sport exhaust, air cleaner etc) generally have better performance with the ring set around the midle if the bike has an aftermarket.

WARNING Please avoid falling into the trap of thinking that the higher the set value, the better the performance.

If it appears that you are losing torque when you get to high speeds this probably means that the ECU value has been set too high and you need to try a lower value.

This is another reason why it is best to start with a low level and gradually raise the knob to the maxmimum setting.

To mount the module on your Keeway Motor Rkf 125 E4 you will need to locate the air temperature sensor (IAT) which is located near the airbox on most motorcycles.

Disconnect the connectors that are already connected to the IAT and fasten the module connectors for Keeway Motor Rkf 125 E4 to the corresponding connector of the IAT using the branch terminals which make the operation extremely quick and simple.
