Understanding ECU parameters (Ktm duke 125)

Post by Jeet892 »

Hi there, I have a 125 cc ktm duke bike. I have installed a big bore cylinder kit (155cc). I want to tune my ecu to handle extra fuel for bigger cylinder but I’m confused about those tables. Anyone can tell me where and what to change to increase 25% more fuel?

I have tried changing desired afr table values from 0.75 to 1 lambda. The engine starts but afr gauge shows afr 19.8, which is very very lean and engine gets shut off after few seconds.

Please help.
