K24Z2 ECU

Civic/Integra/etc with a K swap

K24Z2 ECU

Postby Brothasit » Mon Mar 04, 2019 6:03 am

So I'm about to swap a K24Z2 motor from a 2010 Honda Accord LX into my 2009 Honda Fit and I need to know what ECU should I purchase. What's the difference between the "37820-r40-a20"s vs the "37820-r40-a30"s? I know the 20s are off the 2010 and the 30s are from 2011-2012 but does it make a difference of which ecu to go with? Oh and the trans I'm using is off the 8th gen civic si so I know for sure I need a ktuner flash.

We do not know what issues you'll run into with your swap attempt. The ECU choice will be up to you entirely. See wiring diagrams for differences. You'll be able to sync immobilizer since the Fit also has the system.

KTuner will not fix the transmission being off.

So I can't recalibrate the ecu with ktuner to compensate the gear ratio versus the stock?

That's not mentioned in the feature set for that ECU type.

Hhmmm....I guess I have to re-evaluate on purchasing a software that's capable in tuning my setup. Thanks for the input!
