Smile AP2 ECU Replacment
I am going to replace my ECU on my 2006 Honda S2000 and was wondering is it is just unplug, remove plug-in the new one and done?

Thank you.

Done as in done working? I believe things like the immobilizer, keys, etc. are specific to the individual ECU. Maybe more stuff. Curious why you're replacing it.

It will not run until your current keys are re-written by Honda. Did you get a key with the ecu?

On my AP1 I replaced my ECU with a used unit from ebay. I needed to have a local locksmith reprogram the ECU to the keys I had. So it is not plug and play.

Thank you for all your replies. I noticed that people were selling ECUs with the ignition and it makes sense now. I was considering replacing the ECU because my car is still having issues accelerating.

There is nothing in the ignition switch that is coded. It is only the key itself (no need to change ignition)

That or the pedal position sensor. I thought it was weird that Honda kept the cable from the pedal to the engine bay and then ran it into the sensor, instead of just putting it right on the pedal.

I believe they did that so they could keep a lot of things the same. Pedal Assembly, hole for cable through the firewall, grommet, etc. Its not just not having to design and build those new parts, its also changing that part of the Assembly process.

So its understandable they still use a cable, that just goes to an APP sensor.
