3.2 vs 3.5 6MT TL ECU

O.k you guys im sure im super annoying by now but i think im going to mod my TL as much as i can this year and maybe go for the highest NA numbers in a base 3G TL... Whatever that is (non built)... However i have a random question for you tuning gurus... I will be doing hondata and ordered a 3.5 MT type S ECU today.. Now random quesrion... Before tuning is there any difference in the 3.2 6MT base ecu map vs 3.5 type S?... Main thing i want is bumped revs to 7000 maybe 7100 and removed limiter and of coarse the tuning lol. But is it worth it performance wise to drive around with 3.5 ecu vs 3.2 for a while?.. Im now broke lmao

^ You can change your redline with Hondata. The main thing you should be looking out for if you dont want to solder is a MT ECU. AT you will have solder a bridge for cruise control.

Simi has a TL-S Ecu for sale. Great price too!

Well yeah.. The 3.5L ECU will run richer on a 3.2L. So don't install it until you get that flashpro.

. Hondata will flash the ecu with new software and wipe the OEM base map. So it doesn't really matter afterwards. Just make sure you get the one that hondata recommend in terms of part number ranges.

he will also throw codes for the ftp sensor. probably wont affect how the car runs, but it will throw the code. I think there was one other sensor, but I can't remember

Okay so in theory a 07 AT dropped into an 03 AV6 would allow for hondata tuning given the right ecu.

No, hondata made it so you can use an AT ECU for a manual application. MT tls ecus are rare and limited.

So the software itself will alter AT ecus to work with manual transmissions to give users more options as far as ecus to buy for the conversion. However as far as I understand hondata does not support the use of an automatic transmission (regardless of ecu) with they're software.

PS: I don't know if "software" is the right term for what hondata is. Also correct me if I'm wrong but the tls 07-08 ecus for automatics control the transmission's sh-awd system and thus cannot be used. The 07-08 base AT ecus can be used because they don't control the transmission.

I was hoping this answer wouldn't come up again and that I had missed something somewhere that had simply been excluded due to need for an 07 trans, maybe with different sensors or something.

In theory the AWD system would be indeed controlled by the ecu but if they were controlled through any part of the ecu that is easily manipulatable it may be supported. however flashing an AWD ecu to use on MT shouldn't be an issue as hondata would simply ignore this extra part of the ecu.

07-08 never came with SHWAD, You must be thinking about the RL. I believe you can still use the AT TLs ecu. the oem map just get overwritten.

and the reason that you can't use hondata on the accord AT is the transmission has 4 sensor on the accord. There are 5 sensor on the TL transmission 07-08. This is also why 04-06 TL AT cannot use hondata. I think hondata website also explains that.

Hey I just asked if AT could work with hondata, then even ammended it to 07-08.

I'm pretty sure asking about using a modified chip and it's limitiations in a thread about using a modified chip and it's limitations is pretty par for the course.
At least I have a j pipe...

FYI 3.2L 04-06 has 270cc
3.2L and 3.5L 07-08 has 310cc

it actually might run lean which is worst then rich
