As some of you maybe aware earlier ECU’s require the actual chip to be removed and reprogrammed then resoldered back onto the board these ECU’s start with the designation MSB.
Here at Empire we also offer this service for early Land Rover Defender’s & Land Rover Discovery’s which have these ECU’s. if you’re unsure which ECU your vehicle is running feel free to send us your VIN / REG and we will let you know which one should be fitted.
