The ECT 2, although monitored by the ECM, only controls high speed fan operation and has no effect on engine functionality. As for the whole starter cut relays (I believe there were 3) aren't monitored either. I had starter relay output from the ECM going to a single relay and never had one trouble code...so I feel it's safe to say there's no detectable line.
As for immobilizers, I am not certain of this part BUT I think 04-07 may be the same and interchangeable. It's 08 and beyond that I know has been known not to work...this I can confirm through experience. I was initially trying to use an 08 immobilizer ECM (key ring) with an 07 ECM and could never get it programmed. Although the brake code would still enable ECM operation through the immobilizer....kind of weird.
The whole conversion was very simple all the way up until I reached connector E (as well as C171)because both cars differ drastically in terms of pinout and locations. There also a few wires I had to literally add into the base 3g TL sub-harness as they were non existent. Wasn't all that bad.

Thankfully a new immobilizer and keys aren't obscenely expensive.

Note, it is for an AUTO. If you have a manual it will only benefit you for immobilizer programming purposes.

^ So basically for the 04-06 6MT, an 07 ECU is needed as well as your harness (if of course you started making them)? That's it?

Anybody can repin their own extension harness. It takes a bit of time to check and re-check, but it's pretty easy work.

You wouldn't necessarily NEED a harness. You could re-pin your current ECU plugs for the newer ECU. What I intend on doing is picking up an AEM extension harness and repining that so that all of the factory wiring remains intact. You can even do the same for the OBD port. Buy a separate plug and create a crossover harness so that you've not doing irreparable damage to what you have if the worst case should happen.

You will need to use the newer immobilizer along with the new ECU, but it's possible that the plug and the pins are the same between the new and old unit. I'd need to check the wiring diagrams to know for sure.

i bought my type-s on dec 17th last year, almost exactly 1 year ago, and am paying it off tomorrow. I have 300 dollars left on the loan. I've also sunk about 6k into modding my car aesthetically and performance-wise over the past year that i've had it. Having an $800/mo payment doesn't stop me from modding my car.
Not everyone sits on a car payment for 5 years.
The real reason there are more modded 04-06 tl's than there are 07-08 is because you can't get a manual transmission on the 07-08 base model, only type-s offered that in those model years. Typically people who mod want a manual. Most people driving auto tl's aren't going to mod.
All that being said, i truly hope that 04-06 gets a hondata tuning solution at some point, because i do believe there is a large pool of owners with 04-06 that would jump on the opportunity.

Well, if you're interested, I have an 07 3.5 ECM that works but has two failed driver that have no effect on drivability. You pay shipping and its yours if you need it for testing and to help get this conversion process completed.
Note, it is for an AUTO. If you have a manual it will only benefit you for immobilizer programming purposes.

Weather is starting to get better up here temperature wise so maybe I'll get to see if the immobilizer issue is true very soon. If it is, I will purchase a new one and a set of keys and go from there.

Don't worry, from 04-08, all TLs have the same pinout and connector so replacing the key ring remains a simple process.

If someone wants to send us an email to sales@excelerateperformance.com with what ECU actually works and what needs to be done with the harness we could have a conversion harness made up. I've already talked to a company about offering a harness for a 04-06 TL that sets up to a 07-08 TL ECU. If that's all that needs to be done then it can be done.

Nothing is being made. We are simply investigating. As others have indicated, there are fewer solenoids on the pre-07 transmissions. Using a 4 solenoid ECU on a 3 solenoid transmission would generate an error.

Hopefully this is what they will find out. If the immobilizer is indeed compatible with the 06 TL ECU, that opens up the market for the AV6-6 as well. That's how I understand it at least, considering the TL ECU is 'almost' a direct swap for the Accord. I'd go so far as to say we wouldn't even need the 04-06 ECU, may just have to swap a couple pins.

Freaking weather here won't break. 11deg this morning. I'll know as soon as I can get out in the garage and was just wondering if they knew before I try.
Then I have to decide if I want to find a 07 ECU or replace the immobilizer/keys and stick with the 08 ECU.

I can't believe all the speculation about the immobilizer module when all someone has to do is look at the part numbers that are listed on countless Honda/Acura parts websites...

Knowing that the ECU for 2004 and 2005 TL is identical and the ECU for 2004 and 2005 TSX is identical, I think it's safe to assume that both part numbers listed above can be used in any of the vehicles listed above as long as they are properly programmed.
Here is where it gets interesting and yungone501 may know more...

OK, notice that the TSX has this part number. What makes this interesting is that people are swapping this later TSX ECU into older TSXs so that they can use FlashPro... and they don't have to change the immobilizer module. So in theory the 2008 TL ECU should be able to be matched to the older immobilizer module.

Eric, how's it goin' my man? I too noticed the same part numbers but have learned by past experiences that Acura has some (yet very few) parts that have the same part numbers but still have a variable that causes non-interchangeability. In all due truth, I feel like there will be no issues from 04-07. But from 07 to 08, I'm unhopeful of immobilizer compatibility. Aside from the obvious part number difference, I had an experience I shared above (I think?) of me trying to use a 2008 TL-S immobilizer ecu off of a spare steering column I had in the shop with a 2007 TL-S ECM and could NOT figure out why I couldn't program the damn thing for my initial startup...yeah, I was a little pissed. :-) My programmer kept saying that there was a "communication issue between the immobilizer and the ECM". But after discovering there were year differences as well as part number differences, I tried using the brake code method to see what would happen. That's when I got my first start up. I basically concluded two things from this: 1. The immobilizer ecu's used a different means of communicating to the ECM. 2. The immobilizers rolling code password was still the same between both the immobilizer and ECM. Number two was confirmed after finding out that Acura still kept the Type IV immobilizer system in 2008. This is where you may be able to shed some knowledge on how the ECM communicates to the ECM. One more thing, the system operation explains that once the password has been accepted from the ECM, it then energizes the fuel pump circuit. I know the FPC module is a PWM component, but doesn't this just sound silly as a means of disabling (or immobilizing) a vehicles engine.

I know that the TSX ECM was manufactured by Matsushita (04-08), Keihin (09-12). From 04-08, the TL (including type S) ECM was manufactured by Keihin. This could mean that the TSX ECM (Matsushita) has broader capabilities in regards to immobilizer ecu communication than say the TLs (Keihin). Two different manufactures with two distinct capabilities...I'm not surprised.

Well, since I don't know much about the immobilizer system, I'll have to speculate like everyone else... 
The later immobilizer modules probably have some additional algorithms that are only utilized by the later TL ECU.
Regardless, the modules are pretty cheap so it shouldn't be a big deal if someone has to buy a new one.
The SDA modules are $36~$38 and the SCV module is $60.

This is coming back onto my radar now. It'll be less of a pain in the ass if we '06 MT guys can just buy an '08 Type-S 6MT ECU for $400 new from Delray and not have mess with the immobilizer. The TSX harness for the older models is only $50 so that's no biggie.

So the '07 has the immobilizer separate? I remember pricing them all a couple months ago and do recall the '07 was more. I also remember the '04 base 6MT ECU was more than the '05 and '06. Odd.
