If I replace my original fuel injectors on my 1992 Mazda B2600 2.6L to an aftermarket do I need to flash the ecu in order for the vehicle to run properly?

What is your question?

I had just recently replaced my injectors and the vehicle is now idling rough. The seller stated that I would need to take my truck in to the dealer and have them flash the ecu so it can accept the new fuel injectors. The reason I couldn’t just replace the o-rings is because 2 injector plastic tips had broken off and that is why I had to buy a new set.

How long has your 1992 Mazda B2600 had this problem?
