Any issues using Integra Type S ecu for cloning?

[Two Step Performance]

Is that the same for FL5? I thought there was a difference between fl5 and de5. Or do i purchase the DE5 tune since it's a DE5 ecu? Just trying to be clear

Great question. Once your FL5 ECU is cloned to the DE5 ECU, it is effectively setup as an FL5 ECU at that point. You would always use the FL5 tune in the FL5 chassis, even if the ECU may have originated as a DE5 ECU. Here is a link to the FL5 tune:

Yes, true, from what I've been told. It's not a fool proof method of hiding your tuning from Honda. It supposedly keeps counters of key turns and mileage, which are also store elsewhere on the car, so with some diagnostics it will be evident that it's been tampered with.

Even with swapping ECUs, you are not hiding your tune unless you also remove the TCU.
