I guess that depends on your preference...if you don't have the electronics to start with, then you have several routes to consider. That is what I have initially faced with both TDI engines I have. The engine for the b3 is no different.
The electronics in no way by any means are worth the 400-1000k *by the time you figure, pedal, wiring harness, pump, MAF, etc* that is being asked for them on the open market in most places. I'd rather spend the money on a good pump from say Giles if I didn't know too much about pumps...or build my own and get plenty more performance potentially for about the same cost.
Yeah...CE2 is nice... and no, its not hard at all. Full tuning ability without having to have remaps, flashes or burns all the time to the ECU to me is much better with extra added old school diesel feel and chatter. I'll take the little bit of noise that comes with it. Additionally, for extreme modification to the pump to allow for more timing advance, etc. etc. you still need pump modification even on the eTDI pump. The ECU does set limits on where you can go unless you have quick access to a chip burner and/or someone with those capabilities. Its def. not all about the electronics of the pump alone. Read about the brick walls that many VE pump TDI'ers have reached in digging deep and you'll find out.
Setting up a correctly done mTDI pump....a completely different story in many ways but the product speaks for itself...
I'd gladly put the Rabbit up if someone wanted proof
Plus....simplicity... on the fly adjustment....its effective, efficient, simple and performs just as well.
Now, if anyone ever revisited the "Standalone" system for pulling the ECU setup *remember our MS conversations?* and then could modify an electronic pump both by electrical and mechanical needs to pull more fuel, timing, etc. Maybe. Those that you have no choice around electronics...yeap, I'll be right there with them if I go with a PD in the 'rado or a CR. My VE motors though....will see the mTDI pump in good form.
