I'm confused on my 2003 Golf TDI ECU swap: SKC, PIN, and WSC?
Currently, I have chipped ECU (original ECU) and large size nozzles.
I've done this several years ago for wanting more power.
Now, I would like to go back to gain fuel economy and have stock ECU and run stock size nozzles.
I ordered an used ECU, and complete set of sock nozzles, but going thru the instruction from Ross-Tech of swapping ECU; I'm now totally confused!
All because of the Immo-3???? I'm not sure what to do? I don't know if I just take out the original ECU and swap the used ECu will do to the car? Will it start or not able to start again?
I'll be swapping my Original (chipped) ECU with an used one, but I do not have any info on the SKC, PIN, and WSC number for both ECU.
What can I do? Totally lost on this.
Any help?
