Okay, I got nothin'. There's Honda guys that change engines like I change pants. Knowing that it might not be too hard to find an appropriate ECU out there to swap in, the trick is knowing whether it's the RIGHT ECU.

I would think that the new ECU would plug up to your existing wiring, but it might give some trouble if it's looking for sensors that aren't installed or hooked up. Tracking that down could be a serious PITA.

How do you feel about hogging out that engine and dropping in a Briggs & Stratton? I understand those pretty well and might be of some use there.

Nope! Welcome to the club.

If you're having fun now, wait until you get a digital fuel economy gauge in the car, a.k.a. "game gauge"!

Having instant & resettable fuel consumption info takes things to different level.

However, the wiring harness and ecu (that's the computer, right?) We're never replaced to support the new motor. Hence my lack of error codes.

Is it worth the trouble to replace both the engine harness and the ecu?
I would say no.

Replacing the CPU is a little trickier on these cars because there is a separate device called an immobilizer that prevents starting up the car unless the correct key is present. The CPU needs to be programmed to match your key instead of the key to the car the CPU was pulled from.

I've heard of mechanics and/or dealers doing that. Do you think they'd be willing to use the ecu I brought them and program it for my key?

NICE.

I see at fueleconomy.gov that the best '02 Civic was rated at 36 highway, 31 combined. Even coming from behind with the automatic, you're smoking that rating. Muy bueno!

Just ordered an ultra-gague, hopefully the instant feed back will help some more.

also, how does one set it to show FE per vehicle like y'all have in your sigs?

I think you'll like the Ultragauge. Here's what I have on my primary screen:

I use the O2 sensor info to monitor lean burn. With an LX, you probably won't want that gauge displayed.

As for setting up your signature:
