99.9% sure the typhoon is exactly the same ecu that lotus use, made by EFI in italy, very good ecu's, EFI make mostly oe fit ecu's very successfully, they are just in a different box that's all, they use a very common processor, the same as the one in my emerald K3!!
They are supplied by SC, Specialist Components, in Wymondham, Norfolk by Simon Hill, who's a very knowledgeable man ecu wise, it's an excellent product.
