From what I understand, 04-06 ECU's can't be flashed where the 07-08 can.
There must be something further complicating this because the next solution looks to be be something other than the stock ECU.
I know the people who built our turbo kits (J&R) have been working on this. But I know for sure he's going to need everyone to be honest with their ability to pay for it. He had people coming out of the woodwork about the turbo kit when he put the feelers out and in the end, 3 of us actually paid.

The '04-'06 ECU's are actually listed as 'REWRITABLE' in nearly all Honda/Acura parts catalogs. I believe there are a few individuals around here running the Hondata tune on ther '04-'06 TL's.

thats right, dealers can reflash the ECUs...it is how they fix software glitches and update patches

I will update here, or start another thread about this when i am done with my testing. I am putting a j35a8 (08 tl type s) engine into my prelude. The harness is being built right now to use the 06 ecu because i couldnt get a full 08 imobilizer system. I have the 08 type s ecu, and will be doing dyno testing between the two once its running.
It is possible to use the 07-08 type s ECU in a 06. All that would have to be done is program the 06 key to the imobilizer in the ecu being used. One thing that might happen, it might get a cel for the fuel pump computer i mentioned earlier becuase it is not present in the 06 car. I will know for sure in about a week when all my parts come in.

From my understanding the 06-08 ecu's are reflashable. The auto ecu's are very similiar to the 6mt ecu'. The pinouts are the same for the 06-08 the only differences is the 07-08 has few additional wires for some kind of fuel pump ecu/controller.

Small update. I have been using an 06 3.2 ecu for the past 3 weeks powering my 08 type s setup in my prelude. The AFRs look good, and since it is a self learning computer it seems to have adjusted good to the 3.5 needs. I am going to be dynoing on this setup this week. Then i will be putting the 3.5 computer in, and trying to get a key made for it. From my understanding since the computers are somewhat self learning, they adjust what the need to (ie:fuel, timing) to achieve the desired results, and no mater what computer you are using, it will adjust the outputs to run the motor most effectively, therefore achieving very similar power results.

another small update. I had my car on the dyno the other day. The ecu could not keep up with the motor. It was running just a bit lean the whole time, so it was pulling timing, to keep the motor running safe. When i hit vtec it went off the chart lean (not sure if it was sensor error, or to much air movement around the sniffer) so i quit there. made 274 hp 235 ft/lbs with the 3.2 ecu on the j35a8 engine.

Another update. I switched the needed wires on the DLC so that i could program the key correctly to the 08 ecu. The HDS unit would not detect the 08 ecu at all. BIG PRoblem. you cannot use the 07-08 type s ecu on the 06 or earlier modles without a wiring headache. I am facing it right now, and will update when progress is made.

Yeah It was my friend, & yeah he works for acura as a techican. & maybe your the dumbass whose car he did that to, just FYI- we took your sunglasses also. Im here to ask a serious question, if your gonna be a moron, then you can just shut the hell up. I thought this was a serious thread, just wanted to share shit with acura members with a serious question. JW if this was ever heard of, its just like switching ECUs on a GSR for a Type-R. What great way to experiment on mods with an idiot like Opel who takes his car to the dealership!

I think i found the problem. ECM pin E14 on the 06 is the K-line output for the DLC on the 06. The k-line output for the DLC on the 08 is coming from a Multiplex integrated control system. Im not sure if it has that in the 06 setup. I will have to try to find a source for the K-line.

That's still some damn good power! Good luck getting that wiring down! I'm sure you will make closer to 285/250 when all said and done. What mods are on the Lude?

i know that adding a Type-s Ecu to the 2nd gens enables a higher vtec engagement and more timing during WOT.
i put down 243/220 on the 99 ecu. ironically the engines have 3.2 litres of displacement but the base tl ecu made the car run super rich.
im positive i make more power with the type-s ecu in there.
point is, TLDREAM, the A/F's may look good but youre probably getting rediculous timing retard with the base ECU.

I think you are thinking of the 2nd gens. There is no way around the immobilizer on a 3rd gen other than turning it off in the ecu with the honda HDS tools, and in to do that it has to be plugged up and accessed through the DLC port.
I just got some confirmation on the k-line. The k-line is only usable on the 06 it does not affect the 07-08, it is present on the DLC but does not have anything to do with the ECM. I have looked over the wiring a few times, and everything seems correct. I may have a faulty ecm.
