What about this scenario.

User has an OFT. Later on buys an FI kit that comes with factory tune that is only on ecutek. Can they use the OFT to copy the original ecu map which is already on the OFT, then flash back a copy of the original tune while keeping the OFT locked to that original ecu. If understand this correctly the OFT doesn't care what modified map is then uploaded as long as it matches the correct ecu type.

Then now use the ecutek to flash the FI tune maps. From what I'm reading ecutek doesn't flash back to the very original map without some changes it'll flash back to an ecutek version of the stock map.

Can you then use the OFT that still has the original ecu map locked in it and unlock the OFT and flash it back to stock?
