hi guys
if i swap K20 from RSX into a fit, completely remove the Honda Fit ECU, and replace with RSX ECU

WHAT WILL NOT WORK ?

i know
-Main Cluster (Speedo, RPM etc....) but that's easy fix
how about
-Radio
-Power Windows
-Power Steering
-Power Door Locks
etc.........??

please help, i am thinking about the easiest way to swap MT K20 into a AT fit !!

 

Isn't the easiest...get the engine...o6+ si or rsx me thinks for the ecu. Hasport everything. send the ecu to hondata with your fit ecu for them to get flashed...or maybe hondata has an ecu..can't remember. That's basically it if I remember right...google here I come.

reflash the fit ecu n run alongside k pro. not a clue what you'd do with just the rsx ecu.

why do you want the rsx ecu felix?

 

Get K-pro instead of the stock ECU, you'll thank yourself later gaurenteed.

 

my car is AT, which means i will need to buy Fit MT ECU and ECU harness then buy Kpro....so that i can swap K20 Mt into it ... it's alot more money

if i can swap everything from RSX that will be a much easier swap

 

I can't think of anything cept the gauges and any/all sensors.but any power options like windows, doors, stereo, etc... I'm assuming are independent. It'd be the first kswapped fit that I know of not using the fits ECU so yea.

 

no
this fit isnt using fit ecu either, and has full autometer gauges instead of stock cluster, and i think it was a AT FIT to begin with as well

 

you have to get the Fit MT ECU and the RSX ECU to get everything working. You can get them all at Hasports. They need to flash your Fit ECU to work with the K-pro (which is the flash version RSX ECU). So you can get K-pro from them, but you have to find the Fit MT ECU by yourself.

 

will need to re-wire A LOT of stuff and make custom harnesses
a bunch of sensors to configure with
the cabin harness is CAN-BUS which you will have to figure a way to work with the K
you will still need K-pro to eliminate the immobilizer
power steering will stay since it's electronic motor is on the Fit's subframe

but First, max the hell out of the turbo L15

 

i think you are just making more work for yourself because you dont want to spend the extra money. just remember,

fast, reliable, cheap. you can only have two.

stop being cheap and shell out the extra money. it will be worth it in the long run. dont take shortcuts.

 

shortcuts could be more useful in the long run

ex.
USDM radiator support is easier to work with for Kswap

 

VERY true, but my jdm rad support is just going to force me to use ITB or get a custom sheet metal intake mani, either way, it will be more badass then being able to take the shortcut of running a stock intake mani.

 

also used a rad. out of an s13 :/ I know they used k pro and some extra ish from hondata with it but yea, not a clue what other ECU they'd made work with it.
