Ok,

Here is my Apexi AVC-R selenoid hosing installation.



Uploaded with ImageShack.us


I have a rich man non sequential conversion.

On the selenoid, the hose pointing to the front bumper is COM port, the one pointing to the engine is NO port.

Symptoms:

With AVCR ON I get 16+ PSI, with AVRC OFF I get stock 8 PSI. Setting on AVCR is a max boost of 0,9Bar.

Is it plumbed the right way ??

Please your help...

 

Check the AVC-R manuel here http://www.apexi-usa.com/content/pdf6115.pdf

Hope this help!

That's an acceptable configuration as long as there are no restricters anywhere. If you really want to, you can swap the hoses on the solenoid to see if it makes a difference (it probably won't matter much though). You can't really screw it up as long as you aren't using the NC port.

I still think you just don't have the duty settings configured correctly.

 

will this install work for sequential?

 

^ No, As it appears he has removed the turbo precontrol actuator while converting to non- sequential.

However there are diagrams and ways you can hook up the AVC-r to control boost sequentaly.

I tried swapping the hoses and nothing really changed, so if this is Ok I´ll play with duties this weekend, if it works shame on me , that´s the first thing you told me...

Thanks..!!!

 

Look back at my post in the other thread you made. you need to start by turning off the "learn gear" permanently (if it's not already off) and turning off the "feedback" on a temporary basis. then drop the duty to say 20% and see if that reduces boost. With the feedback off the duty value is the only thing that really affects the boost you will see. The target boost setting is only used for the feedback control.

 

Hi,

Just wanted to say the AVCR worked out.

Followed ARGHX advice and is actually controling the Boost on the car.

Thanks a lot, and now any fine tuning advice is welcome. Specially to get rid of the lower RPM turbo lag.

Thanks..!!!

 

I would leave the feedback off for now. There's nothing wrong with it, but you really should try adjusting it in open loop first. When you set the closed loop control (feedback speed and target boost settings) it gets more complicated. You can adjust the start duty map (which is just a 1 dimensional scalar) or go into your 2 dimensional individual gear maps to add duty cycle in the lower rpm range. It will vary a little bit with each gear because of the way the engine load changes. I wouldn't go increasing peak boost though... that seems risky at this point.

 

Ok, so right now you are running fully open loop boost control. It's almost like a gear-based MBC, or a "dumb" EBC like the AEM Tru Boost. So first try the Start Duty setting to see if it improves low end spool (leave the main duty cycle settings alone at this point). This is a scalar setting for each gear, and I think it should still work even though you have the feedback off.



Try 10%, 20%, and 30% for each one. Then try adjusting by gear... lower gears may want a greater % start duty. BUT if you are having traction problems, you could also try a negative value in the lower gears. Hypothetically You could have -10% in 1st gear so you don't blow the tires off, then +30% in 2nd gear, then +10% in 3rd and 0 in 4th or 5th. It just depends how the car behaves... the exhaust and the gear you are in has a big effect on it. The AVCR can be really complicated or it can be really simple. It just depends how much time and testing you want to put into it.

If for whatever reason the AVCR isn't responding to the START DUTY settings right now (probably because the feedback is off), you can directly increase the duty cycle for each gear using the 2 dimensional maps.



So if it's laggy under 4000rpm, ramp the duty up. If it's at 20%, try raising just those areas to 40%. At some point you could try setting the closed loop settings. You will have to be careful about the way you set the target boost and the feedback speed or you can have spiking. I believe the AVCR is a proportional-only system, very similar to the way Mitsubishi does their load-based factory boost control. So the feedback speed and target boost are important and they will take some time to get right. That's why I suggested you leave them alone for now.

The final option is to just keep driving the car for a while and make sure it is behaving before you go mess with something as dangerous as a boost controller.

 

Wow...!!!

Excelent information again..!!!

I´ll try this tonight...

Gracias..!!!!
