EBC w/ S300 having weird problems with Smanager
 

I'm having a strange problem with Smanager and EBC.

When EBC (Boost Control) is enabled, Smanager will stop recording what looks like as soon at it activates and also Smanager stops working.

When EBC is disabled in Smanager I have no problem recording and having Smanager live all the way up the RPM band.

This is the first time using this function on this ECU. Is there a chance that this problem is hardware related?

Thanks,
Ryan

Had the same problem. A friend installed the EBC components, he made a short between two pins of Q29. Post some pictures of the board, front and back!

Ok. I will do so tonight when I get home from work.

Here are some pics. Everything looks right as far as orientation of components.

Re: EBC w/ S300 having weird problems with Smanager
 

Yup! Everything looks fine! What about Q20? Are you using A11 as EBC solenoid output? EBC solenoid has +12v supply?

Re: EBC w/ S300 having weird problems with Smanager
 

Yes I'm using Q20 on the other end of the board. It also looks fine.

I posted on Hondata's forum and Spunkster said I need to swap out the non resistor spark plugs for resistor type and only use resistor type. I went to #8 plugs from NGK but the V power are R series. I can't find a #8 plug from NGK that is resistor type so I think I will go back to #7 plugs.

That's not the problem, actually you can enable the EBC when your car is idling. Hook a led and a resistor to A11 and +12v and check if it works. Use this parameters, the led must go on

Is Q20 installed? Its position to the far upper right is no in the pics.

Is Q20 installed? Its position is on the upper right not shown in the pics

Re: EBC w/ S300 having weird problems with Smanager
 

Yes q20 is. There installed. I just didn't post the photo bc it looked correct. It is there

Any particular size resistor and LED? Can I get those items at say a radio shack or similar?

I can hear that the ECU does control the solenoid. I can change settings and hear it clicking but I can't get it to buzz as if it's working.

I did plug in the settings as followed

enabled PWM
Activation @ 0 Mbars
fixed duty cycle at 31%

From what I red the solenoid should have started to activate and it did not. When I click the normally open or closed tabs I can hear the solenoid click over.

Just use the test function in the online menu.

Re: EBC w/ S300 having weird problems with Smanager
 

Ok.

I just did that test and the solenoid started working but I could not turn it off. My computer disconnected from Smanager and can't connect when the valve is working. Now whenever I turn on the power in the car, the solenoid is buzzing and I can't connect my computer. If I kill power to the solenoid I can hook up to Smanager fine. The problem is only there when the solenoid is activated.

Changed the plugs and still the same thing.
