K20A3-auto ECU Reflash

Seriously thinking of getting my 2003 RSX base auto reflashed, but I have some questions. 1) Planning on getting RH, RBC IM, Injen CAI, & Custom Exhasut done as well. Should I get these "bolt-on's" before I get the reflash? Or can I get the reflash and then add the bolt-on's?
Thx all, just wanting to know before money get's spent.

Also I know most folks dump on us auto folks, but I am just trying to get as much bang out of my car as I possibly can before having to do a full K24 engine drop, so any help on the topic I would appreciate. I'm here to learn not get jumped on by the knuckleheads.

Thank you

The reflash is not designed for changing manifolds.

Oh okay, good to know.
So is this particular reflash just for the RH, and CAI only? Or say if I did add, a custom exhaust, RH, CAI and IM would I then need to look at trying a "duel" ECU set up and get the full K-Pro?
I've asked a few people that already have K=Pro's running in the Auto RSX and they claim it is possible, even though I know Hondata does not support set-ups such as that?
Just want to know if I want spend the $300 for the reflash or save for the K-Pro instead so I can add the bolt-on's I want.

Any info is as always appreciated.

Thank you

To anyone,
I'm still thinking of getting a reflash, even though it's not recommended for after market intakes? What I wanted to ask is, if I was to run a "duel ECU" set up, would a reflashed K20A3 ECU work with a "K-Pro'd" PND ECU in tandem? Even if there was the correct pact harness connected?
Now I already know the HONDATA does not make K-pro for Auto transmission K-Series, but regardless I know a some that have done this set-up with the K20A3 with no issues other than getting a fabbed up harness.
Anyway, anyone able to give any kind of insight on this "possible, or not possibility"?

Many thx

Anyone???
No one has any insight on this???

As mentioned I know K-Pro is not for "Auto" Trans, but could this be a possibility? There quite a few running "duel" ECU's on the K20A3??
