So, now as its own theme. Volvo 850 MJ95 2.5 10V, KME Diego gas system, replacement engine MJ96 Some time ago, after the engine change in the car, the MKL started and caused the error A2, 1-1-3. I then checked the vacuum, resealed all injectors (gas as well as gasoline). A year ago, the Lambda probe came new (NGK) and also the temperature sensor for the cooling water is new (display also shows 90°C). From the software of the gas system I take that the Mot In the stationary gas the injection times should be 3,6-3,8 ms. With me it varies between 4,5 and 5,2 ms. Also the transfer of the lamda probe does not jump between 0 and 5V but hangs in the fat area at 5V. On advice from the forum I installed a different petrol pressure regulator. Without noticeable influence. Today I wanted to write a new petrol map for the gas system. So the control unit pulled overnight, 20-30km to learn After 100km I had almost 100 points in the map and switched to gas. The gas map gave me significantly lower injection times. As if I switched back to petrol on test basis. Even now the petrol times were significantly lower. I was in danger with cruise control at 3000u/min and 120 km/h. So clear out on a rest stop petrol map and rewrite. Thought, maybe the ECU caught itself again. Suddenly h from me again high injection times. Switching to gas, again significantly lower. Suddenly my gas times go up. Back to petrol. Now suddenly the petrol times are back in the low range. So I can no longer help myself and therefore ask for advice here. Where can I still start? Does the control unit have one away? Is an injector hanging somewhere? Gas pressure regulator works Lambdasonde should also be able to give its temperature sensor also normal values In the appendix times my Map from the KME software. Mind you, I’ve been driving at constant speed and same speed all the time. Thank you Janko
