Hello all i got a mines ecu from ebay japan for real cheap i thought it was worth a try to get cheap upgrade for now, the owner said it was all good etc so i installed it today got reds fuel pump came on etc but wouldnt fire just cranked constantly, could it be the ecu was for auto rb20? or could i need another crank angle sensor maybe? i havent checked if im getting spark yet but does anyone have an idea what it could be?
ive attached the photo of the ecu i bought below
cheers
