Hondata

Hello,

I'm swapping my Honda fit with a JDM K24A using a 2006-2011 civic SI ECU. There is no dedicated spot for Honda Fit 2009-2014 so I put it here.

1. Will this combo work with a Flashpro? What modifications on the ECU/electrical side will need to be done to get it to work?
2. Will I be able to get A/C with this combo?
3. I was told there would be CANBUS issues communicating between the dash and the ECU and may get an error code. Is there a solution to this?

Thanks,

Ted C.

That is not a swap it was intended to use with so there may be issues and is not something that we recommend or support.

Thanks for the response.

Ted- where did you end up on this?
I actually did this exact thing (jdm k24a, 08 si ecu, 11 fit) and daily it. As mentioned, this is not very common and I figured most things out on my own.

1. Will work if you use the flashpro that matches the ECU. B and C will work fine, will need to re-pin A entirely. Get the pinouts for the fit and civic and match them up as needed. C101 will also need to be re-pinned using the same method. Get the C101 and A from any junkyard 8th gen, doesn't need to be SI.
2. I didn't, but where I live AC isn't needed and was more trouble than it was worth. Physically, you'll need to trim the core support back a bit to fit the compressor. Will also need to have a shop make you new lines to tie in. Electrically, fit needs to see the pressure sensor that the civic has to make it happy. VTEC academy youtube has an episode on this with a K24Z.
3. Canbus codes can be turned off with flashpro on the misc screen. No issues that I have found so far and everything works on the dash.
