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.

I'm about ready to pull the trigger on getting my ECU jailbroken for Hondata. I liked the idea of cloning my ECU, until I read a few posts in this thread. The obvious and only reason I would want to clone is so I don't get questions from a dealer, if (BIG IF) my car ever had to visit the dealer. If it is possible for them to interrogate the car and determine that the original unmodified (not jailbroken) ECU doesn't match information from other modules in the car, I may just jailbreak my OE ECU. Can anyone confirm on the possibility or maybe even the likelihood of a dealer catching this?

I've been told there are counts (ignition key turns, etc) kept on various control modules that won't match if you swap in a stock ECU for a dealer warranty issue. My tuner recommended swapping in a Type S ECU for flashing tunes because 1) if something goes horribly wrong in the flashing process and the ECU is damaged, you've got your stock one to fall back to, and 2) the Type S ECU is the same as a Type R ECU but for some reason is lower priced, so it's a more cost effective purchase.

My stock ECU sits pristine in my basement while my Type S ECU has been flashed 4 or 5 times problem free. I've been to the dealer for basic oil changes and NYS inspections with zero issues.

Very helpful...thanks! Another thought I hadn't considered...the potential for flashing issues (although I would assume to be low?).

By chance, do you recall if this was the DE5 P/N you used: 37820-6PV-A03

The dealer won't interrogate you over a tuned car because you brought it in for an oil change, to rotate the tires, or to fix a power window motor. They would have no reason to. If you blow up the engine, swap ECUs, and then take it in for service, that's an entirely different situation.
