I have a jet-ski, Polaris Msx 150 that fits this engine from the automobile industry used for many applications including quads, snowmobiles, and more. It is a two-cylinder with turbocharger kkk k03-managed electronic Bosch Motronic ME7.4.4.
The control unit has an adjustment so fat that remains unburnt fuel that ends up in the cup and deteriorates rapidly the oil. I do not know the values of afr original and I'm not going to drill the exhaust manifold for mounting a second probe, my idea is to disable the lambda from the ecu and use it with an external tool to check the stoichiometric ratio in the processing phase. Among other things, on page 19 of the manual that I'm attaching it reads that the engine works in closed-loop between the minimum and 4000 rpm if there is no acceleration.
Is there anyone who knows how to make this type of change? I also have other parameters to change, I unfortunately do not know where to put the hands.... write to me in private that we agree
