Been looking around at getting a new lump for the new year and come across a decent 406, bosch pumped etc.
Question; the semi-ECU controlled advancing system on the fuel pumps; how can this be removed/overwritten?
and also, just to confirm, these blocks were the DHX lumps similarly to the modern Xantia XUD's? with the coated pistons etc?
Have i got this right?
much love x

Replace the pump with a normal Bosch.

I thought it was only the DHYs that had the coating on the pistons.

Rip off new Bosch and replace with old style one.

Yeah the only way to do it is swap the pump. It's really easy to do it while the engine is out anyway.

To be honest if you're getting a new lump then it makes sense to change the belt etc anyway, I've just fitted a dhx myself and swapped the pump for a proper one.

Hmmmm tell me about these coated pistons? The only annoyance about the pump on mine is that it's armoured and I can't adjust the main fuel screw :/ Otherwise business as usual.

Spoke to Ruan about this and it's a pita to try and compute a semi ECU pump; easier to just put a normal Bosch on
