- 2013 tdi golf DSG. 1995 EVC AHU Tdi, Dsla 1019 injectors, Vnt15.
Hello Everyone:
I am in the final stages of a 1995 EVC Tdi conversion and have a question for all those who have gone before. I have a ahu engine with dsla 1019 injectors, Vnt 15 Turbo and EWB o2b transmission. The ecu is a chipped jb 68 pin unit and I am running a custom tune, which i suspect is the culprit with the engine vibration. I'm trying to gather info so I know where to be looking within the maps. There seems to be some discussion of PID mapping but very little explanation of resolutions in the forums.
Basically at Rpm's between 2000-3000 ~ and vehicle speed Above 40 mph the engine begins to vibrate, shudder, judder whatever you want to call it when any thing over the slightest bit of accelerator is applied. the turbo doesn't go into limp mode and otherwise the van drives fine, egt tracks vehicle speed pretty well. once the Rpm speed increases to 2900~ the engine smooths out and all is well. Anyone's' with personal experience of this phenomena input would be appreciated.
