Felt a bit adventurous and decided to ebay the ECU off a wrecked 2008 EX-L Sedan (2.4...obviously). It seems that the only difference between the 190 and 177 hp versions are a) bigger exhaust diameter (2.25 vs 2.5") and b) higher rev limit.
Assuming I can actually get the ECU installed, I plan on taking it to the same dyno place I used previously and doing a back to back run with the ECU reset to negate any sort of "learned" advantage. It should be immediately obvious if the rev limit has been raised. Some problems I foresee:
But either way, I'm going to take one for the team and see what happens with an ecu swap. On the plus side, swapping ECU's is really pretty easy...already removed my ecu once to look at it.

- -EX-L has a lot more gear than the LX has. Who knows if the ecu is going to freak out because seat heaters are missing. Navigation vs. no navigation...list goes on and on.
- -Immobilizer might be screwed without reflashing the ecu. I'm hoping the immobilizer module is contained to the steering column. I know it talks to the ECU, but I'm hoping it's just a "go/no go" signal.
- -The '08 might not have any number of ECU updates that have occurred in the 5 years since it came out. I seem to recall there being a few that are mentioned around here.
