Has anyone had a failure of a JHP eprom?
What are the Ultimap eproms like as a replacement. Am I right in saying they are programmable? |
i was told that the 748's are poo poo when chipping there a real pain to get the right chip i got some pipes Leo vince and they came with a chip but the guys at carl harrisons said that it was a poo chip and sorted me out one that was correct for no extra cost i think there all chips which can be erased and programed if there just pics then they cant be overwriten ur best bet is to cotact JHP and see how much a chip is shouldnt be no more than 25 quid
good luck
