nope there eprom
most of the ecu's have pn ending in BE these are what most of the ebay chips are for, i bought a powerchips eprom ( to suit BE ) out the classifides section just to read and have a look what they did, cost me £20 posted if anyone wants it make me an offer. it's only offset map tho
have other maps for BE ecu may get round to testing them at some point tho keep saying that and can't see it happening now, defo won't be dynotesting them anymore as now have a checksum free ecu so much easyer to change things so will be useing that from now on
