Is the immobilizer disabled or did you get your keys programmed for the new ecu?

I was able to, they didn't fight or argue with me. Shot the refund out very quickly!

No, it is still enabled. I will have to get the car to a Honda dealer so they can program the key to the ECU. I have yet to start the car so lets hope there are no other issues hiding. It's taking a bit to rewrap the harness after removing all the wiring associated with the Air pump.

Me too man! If the ECU didn't take care of the issue, I would have gone back to the plan of checking wiring with the PGM FI Relay.

That's weird because the immobilizer should not let the fuel pump prime.
Hope its going to work out for you.

Oh, really? I assumed it was like newer cars where it would run for a second or 2 then die...hhhmmm, I will try and start it when I get the harness taped up and loomed. I will post what comes of it.

Installed freshly loomed harness with new(used) ecu. Green key light flashing, as expected, I will need to have the ecu programmed to my keys. Also getting a p1415 code which points at the air pump low voltage. No surprise there since I do not have the air pump. Izze air pump simulator is not installed at this moment. I will install it soon and recheck code.

Towed vehicle to Honda yesterday. Programmed keys to the ecu and car starts and runs just fine. IIITTTTT"S AAALLLLIIIVVVVEEE!!!!

I've removed some weight from the car and installed the Backyard Special seat rail (BYS). The car doesn't feel as strong acceleration wise. Of course there are other possibilities, possible bent rod or cat clogged up from all the fuel ran through the engine. I will be doing a compression test next.

I was told the ECU came from a 01 but had the 02-03 part number. Spark plugs have less than 5k miles on them. I sprayed them with brake parts cleaner before taking it to Honda for the programming, would this be a problem using brake cleaner instead of carb cleaner?

Default Compression test results

All cylinders are in between 215-220. I didnt realize it would help to have the throttle pedal held to the floor, so the numbers could have been better. Either way, healthy engine!

I plan to run seafoam through the fuel system and the crankcase. Attempt to get rid of any bs that could have been created from the hydrolock situation.

Test pipe came in. I will install that and see If that helps the bogged feeling. Fingers crossed.

Test pipe installed last night. Test drove this morning. Car still felt the same. Reset ECU at lunch (pulling back-up fuse). Drove hard and used the VTEC button as often as possible. Car feels like it's old self. I know it shouldn't have been the ECU reset. It most likely was me not pushing the car into the powerband enough.
