Hi, sorry to revive an old thread. But I’ve just bought myself a Grom PCV and was hoping you could pass on the CBR300R PCV maps. Cheers
Just want ask a few questions, if you have purchased a Grom PCV, is that the FI controller??
I bought a PCV FI controller for my CBR250R when I fitted the kit to take it to 305cc.
These are not plug and play with a downloadable/uploadable function, it already has 15 maps/selections installed, you need to select what you have done to your engine.
If Grom engine is standard it is best not to fit.
Settings are affected if piston, camshaft, exhaust has been changed that is why you have 15 selections and the!!
Product number is 05-04-0016, applicable model. Grom (JC61-1000001)
The above will not fit the CBR300R (286cc) engine or the BBK 305cc engine.
You need the:
Product number 05-04-0018, applicable model CBR250R (305cc) (MC41-1000001-1399999)
This FI PCV has 17 map/selections.
Once you have selected the map for the changes to the Engine, whether piston/cams/exhaust or any combination. When you have selected and loaded that map you then need do the fueling.
You start of at 5, you need more fuel you increase. A sports exhaust will have deleted the O2 sensor so you need to set up using an Air Fuel sensor on preferably a Dyno.
If I have muddied the waters sorry. I fitted racing cams, 305cc hi-comp piston, straight through Akrapovic exhaust and it were a pain.
