Fit reflash, re-tune?

CaVaFit · #1 (**permalink**) 08-07-2009, 03:23 PM

Hello all,
New to the site. I was wondering if there is a way to reflash the ecu or if there was some sort of re-tuner (plug and play) for the 07 Fit, I also drive a 04 SVT focus and for our cars if they are bone stock you can get a tuner > SCT 3, Mafia, Diablo, and so on. They plug into the OBD scanning plug and so on... I'm pretty sure you guys/gals have something similar but i can't seem to find it anywhere. I'm looking to add a bit of power to the fit but nothing that changes the tone. My SVT's supercharger and exhaust are super loud and annoying at times so I would like to keep the Fit as quiet as possible..
anyway any help is appreciated.

there's nothing available. it sucks.

Well, nothing until you step up to something like the AEM F/IC . . .

The only reflash available is the Hondata Flash for the KW kit.

would the hondata re-flash work for a turbo setup?

nope. it is an exclusive flash specifically for KWSC kits

Kpro is put on the K20 ECU. What is on the Fit ECU running in conjuncture with the K20 is a bypass not the Kpro itself.

2bad, AEM F/IC it is then....

I am working on a solution to this problem. The FIT ecu has the capability of J2534 pass-thru flashing as a standard since 2008. I am awaiting the Honda HDS software to arrive right now (shipped last friday). I'm hoping to be able to capture the init/read/write commands and have some help in re-creating a utility to do the same thing. I am still researching and have come up with a bit of information so far, but still far from something useable.

Once I know the exact microprocessor in the 2009 ECU, I will need a ROM dump. Then I can begin dissasembly in IDA Pro to try and locate the various tables that will be beneficial in tuning.

I will be waiting for this....

why a 2009 ecu??

ev8siv3 · #16 (**permalink**) 08-19-2009, 09:57 PM

I generally start with what I own then trickle. We also have a 2008 Fit ecu to work with as well. Should cover 2007-2010!

actually the 07 and 08 ECUs are different.

Do you have any information about the chip inside them? If we can get a unit out of each model year that would be best. I'm looking for a 2007 ECU out of a wrecked or unused car.
