I am having some issues with my MB c320cdi 2006 w203 (no DPF from the factory). I am tuning my own car for the fun of it, It has a hybrid turbo gt2056 taken to gt2365, FMIC with pipework, 3inch exhaust. This is my first time working with EDC16, I have done lots of research made myself a map pack etc. There isn't much information out there for the EDC16CP31 and from what I have seen/ read it's quite different from the VAG and BMW EDC16. I have managed to find some EDC16CP31 hex and A2l files to try get an understanding and identify some maps. I have never tuned a diesel, my line of work usually involves gasoline engines running motorsport ECU's.
To begin with I couldn't get it to inject fuel, no matter how much fuel I add to fuel and smoke maps I cannot inject anything higher than this: So I de-calibrated the duration map, and set the fuel demand below the maximum logged limits and I can trick the ECU into fuelling 100mm3. I assume there is a torque/ fuel limit I have missed?
Secondly, I cannot get it to boost, I have tried changing base map, atmospheric protection map, various actuator maps and none of them make a difference. The engine looses boost in the midrange, but the actuator position is nowhere near any of the actuator maps. Base actuator, dynamic actuator, P3 limit, Base MAP : The more I think about I think I have missed torque limiters somewhere? Does anyone have any experience tuning these and would be willing to help, I am willing to pay for this help. Also EGR function looks different to the VAG/ BMW systems so I am struggling to work out how this works... I have included my map pack and original file.
