At guys are screwed yet again, the 07-08 AT has 4 shift control solinoids vs the 3 the 7th gen and 3rd gen TL have. To make matters worse you can't just throw the newer AT in , the engine bell housing pattern is very different so you would also need the 07-08 engine to go with it.

But MT looks pretty damn doable now that I have looked at the diagrams and researched the ther subsystems.

 

O-kay....not so pissed anymore....

Thanks for the input Paul!

 

I just did a quick comparison of the 06-6MT to the 07 ECU pinouts and at first glance looks like it is one for one compatible. As Paul says, there are A/T pins that aren't matching up.

One pin, K-Line exists on the older but not on the newer that has something to do with the HDS.

I may just pick up a used 07 ECU and see if it works......

I also found a source for the ECU plugs. Ended up ordering the parts and was going to use the AEM harness to cut and pin into the plugs to eliminate splicing. Could be I won't need it.

I'm concerned about the VIN matching because the inspection here is strictly OBDII scanning and the fact that the licensing from Hondata is based on that value.

 

K-Line is for diagnostics. It runs to the OBD2 port. This is the communication line that is 10.4k bits per second. It can be left in place if the same pin location is blank on the 07-08 ECU. You would have to add the CANH and CANL lines to the OBD2 connector. Hondata sells the CAN line cable for the TSX and it would probably also work for the TL.

 

Having a legit tuning option finally is great news, but I need answers to the above question. This seems pretty similar to the SCT tuning I used to use on my old cars.

 

Does anyone know if this can be used on a 6mt cl-s? Or are the ecus totally diff from the 3gs and we'd have to look into swapping ecus if that would even work?

 

While I certainly understand the volatility of re-writing any type of software on any type of electronic equipment as well as a car's ecu when it comes to power outages, and the obvious increased risk the longer the re-writing takes, I still don't understand why it's such a taboo subject with Hondata and ISO-9141. I mean, Subaru used it in the WRX/STI right through 2006 and I believe Mitsu used it through the EVO 8 or 9, and yet Cobb, as well as others has tunes galore for them. I bet 65-75% of all mid 2000's EVO's and WRX/STI's are tuned with something and you don't hear about them locking up ECU's.

I dunno, I think most of us are pretty big boys, understand the associated risk and would be willing to accept full responsibility if something goes wrong. I'm sure a used ecu from a wrecked '04-06 TL could be had for less than $250 or so. Even a new one can be had for low $400's, except the '04, which is upper $500's for some reason.

 

check out what it says for 06 6mt for ecu?????????????????

I'm sure Hondata is working on this matter as which easiest route and less money as can be. Give the credits to them as they will be putting $ on these tests for us. I'll be waiting patiently.

 

Excellent info, thanks!

According to the ETM, K-line also exists on the 07 DLC.

I'll also need to move pin 14 to pin 1 (10.4k comm line) because pin 14 is also the F-CAN Low line.

Do you know if any of these lines need to be shielded?

 

DAMN! What I miss If PAUL is chiming in then the minds are rolling for a solution!

 

What, that it's re-writable? That's been established already, the issue is that it takes so long to re-write which is what makes it higher risk.

 

Make your DLC match the 07' DLC. The K-Line is also used for the ABS module, so leave it intact. No shielding is needed. The CAN lines are differential and usually twisted, but the short lengths involved here won't really affect the performance if it's not a twisted pair.

 

Not sure if Flash Pro comes with base maps. Does the Flash Pro for 8th gen civics come with base maps?

 

I've done a little more comparisons and the 07/08's have a 2nd coolant sensor, Starter switch detection (on/off) and something to do with engine pulses.

I've got to dig up the details on these circuits.

 

Is it to much to ask for Hondata to give us a little summary on the issues with the 04-06 so that we can understand exactly what we would have to overcome? After all its Christmas!

 

so this will NOT work on automatics? or am i reading it wrong?

 

I think they are referring to 04-06 AT, since OP is running this on an 08 AT.

 

Yes they come with base maps and yes 8th gen civics do as well....

 

dear god why is time SLOWING DOWN while I wait for this to arrive?!?!

 

Do you guys think the canadian 07-08 ECU is the same as the US one? I hope this flashpro will work on canadian cars as well...

 

It's all one and the same my friend.

 

Look again at the pinouts, yes most of the signals line up, but they are moved all over the place.

As far as the VIN, if you do a replace ecm/pcm from the HDS is will put your vin into the ECU.

 

No, it will not work with the 04-06 tranny directly, the 07+ AT has a extra shift solinoid among other things, you would first have to swap to the 07+ AT and since the bell housing bolt patteren is very different you will also need a engine from a 07+

 

excuse my ignorance but what benefits would a basically stock base '08 with an injen intake expect if anything? and worth it?

 

I've got an 06/6MT and the ECU pinout is pretty much one for one.

The 04/05 is all over the place.

As for the additional circuits, the 2nd ECT is at the bottom of the rad and switch detection is easy but I can't figure out where the engine pulse output is going. It's an output so it shouldn't cause me any problems as long as there isn't an input expecting a signal.

 

Subscribed.

I would preorder one tonight if it was available. Hopefully it works out for us 04-06 guys.

 

Do you know the production date on your car? I have to check mine, but I'm pretty sure it was Summer 2006, towards the end of the year's run. Do you think it's possible that some of the '06's are actually running ISO 15765 instead of 9141?

 

03/06 for me and I have an RDA-A24.....

I would doubt that they would put in the newer ecu but crazier things have happened. Do you know the part number of your ECU?

 

Another question pops into my head.

The 07/08 base is only 5AT.

So that means if we do a ECU swap, we need a RDB-A0x?

 

Just a crazy thought. I haven't checked it yet, but I will.

Is that the part number for one of the Type-S 6MT ecu's? It's odd the two Type-S's are different, but the base shares the same number for '07 and 08.

 

no we need 37820-RDB-A04 07 tl type s the 08 is 37820-RDB-A12

 

The pinouts on the 07 and 08 are identical. Does anyone know what the differences are between the different part #'s? The Hondata site doesn't list the 08 Type-S ECU in their table. The part numbers below are from the acuraoemparts.com site.

2007 TYPE S-MT 37820-RDB-A04
2007 TYPE S-AT 37820-RDB-A55
2007 BASE 37820-RDA-A84
2008 BASE 37820-RDA-A84
2008 TYPE S-MT 37720-RWC-A01
2008 TYPE S-AT 37720-RWC-A01

2007-08 Acura TL Base
RDA-A82 through RDA-A84 FP-TL-US

2007-08 Acura TL Type-S
RDB-A02 through RDB-A63 FP-TL-US

 

gotcha.

i have a 07 TL-S (AT) so i'll be sub'd to this thread.

 

Hopefully Hondata will clear some stuff up.

 

My bad.....They changed the item # for the 08 Type-S

2008 TYPE S-MT 37820-RDB-A12
2008 TYPE S-AT 37820-RDB-A62

 

NEP = E23, right? It's for the Active Noise Control System, which was only offered on the Type-S. It's an RPM pulse output.

 

That's it. Thanks!

 

I've been talking to my friend at a tuner shop here, he works a lot with Hondata, I'm gonna see what we can do to make this work, hopefully we can make something work so we dont get left out.

 

Where exactly is the ecu located? I would like to check the part # on mine.
