I'm very familiar with Hondata S300, but this is the first time ive messed with the boost control option and i have a few questions to figure out. I looked at the hondata help section but some things aren't clear.

1.) The solenoid frequency option, what is the for exactly? Use?

2.) I wired up the hondata solenoid to 12 v switch and to the A11 pin on the ecu. Is there a way to tell if the solenoid is actually working?

3.) Activation Pressure is used to start opening the wastegate. if i set it to 7psi with my tial wastegate. Does that mean it will fully open at 7psi? I'd like to push 15psi

4.) For use with my hondata solenoid, should i select the max boost a 100% duty/normally closed option?


thanks!

 

4. Should be unselected if using a MAC solenoid.

 

No activation pressure us when the solenoid starts working and will
Help keep the gate closed longer

You'll hear the solenoid click. Did you have all the boost components out into the ecu?

Set the frequency to 27-30hz for the Mac solenoid. It increases the response of the solenoid.

You gave to play with the duty cycle and determine what duty equals what boost pressure

 

so when i turn the key on, i should here the solenoid click right? I did test it on a battery..i grounded one wire and touched the positive terminal and i heard a click before install. And for some reason when i got the solenoid from a friend, one of the wires had a eye hook connector on it, as if it was grounded before. Does this thing need to have a ground. I had the ecu chipped by xenocron and the boost control components were installed

 

yes. needs to be grounded. Won't get actuation of the solenoid until its being used. But there is a way to test it.

This video shows how to test...... It says AEM, but its the same ****.


Here's how they're used in an industrial application... And yes, its in Mandarin.


Another industrial application.


The blocks (outer casings ) for the valves are made in 4 countries , specifically. (sorry for the large pictures)


There's also the one in Auckland, NZ

 

so it has to be grounded? The hondata instructions say that one wire goes to a11 and the other to a switched 12 volt. is it grounded through a11

 

1.) the higher the frequency the smaller the duty cyle % window will be i.e. I have seen 40%=10psi and 45%=40psi when the frequency is set at 70hz or more... I like mine at 40hz any lower and the solenoid doesn't respond as fast imo... when at 40hz I usually see gate pressure at 40% and max boost around 70% on big turbo/wastegate cars...

2.) you seem to have it wired correctly. go to "options" make sure real time update is selected,then click the lightning bolt to put the ecu into real time and then go to "online" and and select test outputs, set the hz at 40 and the % at 50 or higher and you should hear the solenoid buzz this is only way to test if the solenoid is working in conjunction with the ecu. as stated above if you just need to know if the solenoid is good just click it with the battery but on the other hand that doesn't mean the solenoid is functional as I have killed 20-30 of those mac valves when using co2 to control boost and it still clicked but was clogged... also take the little filter out I can explain if need be but its a lot of typing lol.

3.) set the activation at 0-1 psi this will start pulsing the solenoid at that boost and then when your duty % is above what your gate spring is at it will start raising the boost.

4.) with a mac solenoid you want max boost at 100% as it is a normally closed solenoid as opposed to a gm unit.


the a11 pin is the ground that's how the ecu works the solenoid it pulses the ground just like an egr valve hence the reason why you are tapping into the egr pin (a11). I can explain how to dial in your duty % for boost by gear if you need some help but its best to do it on a dyno that way your settings are close for street/track tuning.

 

Follow the Hondata instructions, one wire receives switched 12 volt, and the other wire to A11

In Hondata, it will not pulse the solenoid unless the motor is running, no matter the activation point, so the car has to be running to test.

Then there is a QUICK SPOOL setting, which basically opens the solenoid ON all the time...so you wont feel any pulse.

you have to lower the activation point as low as it can go, and lower the quick spool to the same value, and then set it to a constant duty, 50% and you should hear it pulse.

a lower frequency will make it pulse louder generally to hear it...and you can log the duty cycle % in Hondata to see if what you think is happening, is actually being commanded by the ECU
