Big bore throttle body anyone?

Did anyone that did this mod perform the ECM/PCM Idle Learn Procedure listed on page 11-230 of the Helm manual? I quote:
"The idle learn procedure must be done so the ECM/PCM can learn the engine idle characteristics.
Do the idle learn procedure whenever you do any of these actions:
-The ECM/PCM is replaced.
-The ECM/PCM is reset.
-The throttle body is replaced."
I can post the actual procedure if anyone wants to try it.

I bought xizor's bored tb a long time ago and tried installing it when i installed the s/c, and found the same problems he did, so I swapped back the stock one.
I think i'll try out the procedure this weekend with the bored tb to see if it calms the idle down.
Here's the procedure:
"1. Make sure all electrical items are off.
2. Do the ECM/PCM RESET in the CLEAR MENU with the HDS.
3. Turn the ignition switch ON (II) and wait for 2 seconds.
4. Start the engine, and hold it at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194 degrees F.
5. Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes."
I wonder if step 2 is the same as just pulling the ECU fuse for a couple minutes?

From Hondata's site:
If you are going to build a K series engine, the best parts to start with are those from the 06 TSX.
The 06 TSX has the following improvements:
Increased intake flow:
Intake valve + 1 mm oversize
Intake cam High lift lobe with 0.9 mm more lift and 12 degrees more duration
Throttle body increased from 60-64mm
Radius on some intake pipes increased from 70-80mm

I was wondering that (and the plural noun "pipes" confused me), but I only ask because if the '06 IM doesn't have an increased runner bore then there isn't any point in swapping it with the '04 IM, which you can easily port match to a bored TB with a Dremel. Might as well just get your TB bored and call it a day.

I need a price estimate on the 06' TSX 66mm throttle body and rubber intake arm. Can anyone help me with that? Probably something from the junkyard/wreckers would be best.

Well didn't have the money a year back anyhow so I guess it worked out.

It looks like where the 06' IM runners meet the head they are identical to an 04 as far as opening sizes. This is from a brief look we took as we swapped the parts on. However, when you feel inside the runners, you will notice a more 'hollowed' out feel and slightly differnt inner shape compared to the runners on the IM of an 04' . Also, the part numbers for the 04' and 06' IM's are slightly different. Lastly, its easier to swap both the IM and TB at the same time due to not having to separate them from each other. You'll also need the intake arm from on 06' if you are running the stock intake or the Comptech Icebox, but not if you are using the Injen, K&N, or Fujita.

just did my 2k6 TB and IA on my 2k5 (no porting of IM)... i having the same idle problems as xivor did.... gonna recheck all my work tomorrow morning...
xavior... are you an 2k5 or an 2k4?
i think it might be the crappy ecu in the 2k5 that are giving us this high idle problem.
i might try the PCM reset...but need to find myself a scantool to play around with that...

btw...throwing a cel now....
got the code checked out by a buddy at acura
intake leak and idling too high...
we checked the volt coming out of the throttle body and seem to be running higher than normal. idle is suppose to be between .49-.51 now it's showing .69-.75, that's why the idle is higher...
he showed me a trick to see if it's the gasket leaking...going to perform that test tonight to see what the situation is...
anyone else with the 06 throttle body on there car, which way did you run the coolant lines??? since the 05 one is in the back and one on the side, and the 06 ones have both coolants on the side... afraid the car might start to over heat while idling too long if they are backwards....

The idle learn procedure supposedly requires an input by the Acura diagnostic tool. Why not fix the leak first, and then get your buddy to initiate the idle learn procedure for you? Then just let it sit there idling at warm to relearn. That could be why the TB voltage is higher. It still hasn't learnt the new idle voltage.

Haven't had the opportunity to go and dyno yet.
Shaang when we gonna go and hit the dyno?
