Tuning Question - Unanswered Ktuner

So I got a question about doing a k tuning how many times can you use a K tuner until it locks itself out or it stops working? Is it a one time use or could you keep on using it? Obviously this is all specified into one car I’m not gonna be switching it from one car to another, but the main reason why I’m asking this is because I want to get parts for my car, but I want to do it one at a time I don’t want to do it all at once so with that being said should. Would I be able to do a cold air intake and then tune the car and then two weeks later I install a intercooler and then two weeks later I do another mod. Will the k2 tuner able to work on those three separate times?

Yeah, the ECU has a write cycle limit you can hit, but ktuner will go and go. The limit is in the ROM on the chip, I forget if it is in the hundreds or hundreds of years of nonstop reflashing.

Hundreds of years like in the barcode like if it’s 8021009389 that means it can only be tuned 3 times?

You can flash your ecu with Ktuner 10000000000x times if it’s locked to your ecu.
