Hondata

Hi guys how are you today! I have question! I have a mac 4port boost control solenoid and i im wondering if anyone here knows where in my ecu it should be connected!😭 i have the ecu diagram and i been try to understand where exactly the boost control goes connected to but without any success! I need that to be able to tune my car also i want to install the continental e85 sensor and that too! I cant find any info😖 help

Here is the ecu diagram

Here is the rest

I'm sorry, but your vehicle does not have options for boost control or flex fuel support in the software or hardware.

Oh men🤦🏽‍♂️ ok i guess i will go for full e85 end manual boost! Thanks for the info!

It is possible to tune with e85 directly with no e85 sensor?

Yes, your tuner should be able to tune that way.

Ok perfect thanks! 🙏🏽🙏🏽 im about to tune soon! Cant wait to see results! I have a k24z3 almost fully built cause i still have stock sleeves, stock cam and stock crank! The rest is updated

Bringing this post back up! How can we get Hondata to update the firmware for the 2009+ TSX flashpro to add flex fuel and boost by gear parameters?

Unfortunately our ecu don’t support it!

Did you ever find a workaround for this, or have you ended up settling for a manual boost control?
I've waited 6 weeks for my flashpro because they aren't stocked regularly in the UK just to browse through the calibration and see no boost control support which I find interesting being that it is on the previous generation.

Nah you have to do manual boost controller or digital boost controller! The ecu dont have any option for! Also e85 sensor are not supported! You have to go fully e85 and so manual test to know the quality or get a gauge to know right way! And get 2 different tune! One for regular fuel and another for flexfuel if you want to run that
