Im an going to avoid replacing my pump if possible, on to some leads as to reprogramming the ecu.
(They are read only, but very old school tech, you can pull the map off with USB ROM readers, play with the data, and write the new stuff to UV erasable chips)
Its like computing in the 80s all over again!
From reading they're MSA11s.
I think they have x2 chips in hi-lo if they're anything like the MSA15s - they're an odd ECU as they're partially 8bit data and partially 16bit data... Not fully 16bit like the EDCs...
Should be able to get some flash erasable chips for it, rather than the UV ones, I think they use 27C256 in PLCC32 - although the 27C designation would indicate they're UV erasable, in PLCC32 they can't be erased - they haven't got the tab you pull off to expose the window to blast it with some UV, you'd have to smash open the package - by which point it's f*cked anyway.
You can just buy some 27SF256 in PLCC32 and jam them in - then you can shove them in your Willem and flash away - keep the originals for if anything happens.
