Hi Gang, found this info while surfing recently…thought it may be of interest to the guys that have or are going to have an AVC-R
Not my post – I just stole it so take the info for what it is worth.
Happy
ALot of people that Jeff has tuned use the AVC-R Electronic Boost controller but do not know how to use it to it’s full potential. I have used the AVC-R for almost 2 years now and have messed around with almost all of the features. This post will provide some simple instructions on operation and proper setup of the AVC-R to further help those who need it.
Install:
I am going to assume that you have a manual and can read the proper installation instructions. If not go to www.apexiusa.com and download them.
Components:
- 1 Map sensor (reads boost for the AVC-R just like a stock map sensor)
- 1 Boost Solenoid (Tells wastegate when to open or close)
- 1 Wiring Harness (Self explanitory, very similar to AFC harness)
- 1 Display Unit (Bling Bling baby!)
Vac sources:
Make sure that you have strong vac sources for all components. If not this can hinder performance and or cause spiking/lagging. I recommend a vacuum manifold but its up to you.
Setup:
After installation you want to properly setup the AVC-R with all correct settings. Go down to etc and click next. setup all sensors and pressure settings according to the manual. (I am not going to write out all the settings when its in the manual)
Getting Started:
After setting all the sensors and checking your wiring making sure everything is in good order, it’s time to start playing with boost. The 2 things you will use the most now are Setting [A] or [B] and Monitor.
Monitor:
Monitor is great because it allows you to watch up to 4 channels at one time. It also has a peak and hold option which is great cause you can watch for overboosting situations. Basically click next on monitor then using the arrows go to what ever many channels you want to watch and click next. Then to switch from one data to another click --> arrow then move up or down to go to something else and click <-- arrow to hold it there. Rev -Y is the bottom setting which allows you to go into trace mode for any sensor. I never use it but its kind of cool. Click next when you are done and you can see your channels.
To use the peak and hold feature, while monitoring channels click the ^ arrow and you should see the channels highlighted. That sets up the Peak and hold. If you just have one or two channels being monitored the peak and hold will be to the side and the real time data will be on the right. I always use 2 channels and Peak and hold. Its a great function. To clear the peak and hold press the --> arrow. To get out of Peak and hold click ^ again till there is nothing that’s highlighted. To get back to any of the previous screens click the previous button.
Setting [A] or [B]
The AVC-R is setup so that you can have two different boost settings aka A/B. I have my settings for low boost on A and High boost on B. You can switch between these two by hitting the --> arrow. To proceed into a setting mode click next. There is also an Off setting which turns the AVC-R’s functions off.
Since most of this stuff is in the manual I will only touch briefly on each setting.
Boost/Duty: (Duty cycle is not for injectors in this setting. It is how hard the boost solenoid has to work to keep steady boost.)
Click Next on boost/duty. Now you see you have boost and duty. click --> to move over and ^ or down to adjust these settings. *Remember the AVC-R reads in kg/cm2 which is not bar. The conversion is slightly less than bar so remember that.
Now that you have set boost you want to set duty. There are 2 things you can do here. Either put it in learning mode or do it manually.
Adjusting Duty: After clicking down arrow and then --> arrow to get to duty set it for around 30%. Click Next and you will see a chart looking thing. You will see it is 30 all the way to the end. This is duty per RPM. To change to learning mode all you have to do is change one thing in duty by pressing up or down. If you click previous button you should see *** which means learning mode is activated. Now if you hit next and then next again you will be in boost per RPM. THis allows you to set boost level per RPM. Once again changing one setting will put boost in a custom mode but it doesnt learn you set it yourself. Ok now we have boost/duty setup it is time to proceed. (side note: Learning mode is the shit and after doing a few pulls it configures your duty. I love that thing)
After using previous button to get you back to the screen where boost/duty was press down arrow and we are at Scramble.
Scramble: No one ever knows what the hell this thing is so I will tell you. It is an orange wire connected to the wiring harness that you connect to a momentary switch (push in and it pops out) that allows you to bump up the boost a certain amount for a certain amount of time. So say you are at .5kg/cm2, and set scramble to .5kg/cm2, once hitting the button your boost will be 1kg/cm2. (I dont use this so I won’t go into how to set it but it’s easy and it’s in the manual.
So we hit previous and now we go down to NE-Point:
NE-Point gives you the ability to put in what RPM points you want the AVC-R to look at (Exactly like an AFC) There are 8 points. Since most of us see boost by 4000 I set mine there and do increments of 500 so I can have points from 4000-8000. For those with turbos that spool faster yuo can adjust it to what works for you.
To adjust just use Up or Down arrow then --> to change an rpm point and up down to adjust. Pressing <-- will allow you to go to another point or previous will get you back to the menu screen.
F/B Speed, Learn Gear, Start Duty:
I don’t use these options really. Its a pain in the ass to mess with them so I am not going to go into it. If you have a question about one let me know and I will do my best to answer. I have adjusted these but found the default settings work best.
F/B Speed: If you are spiking or not building enough boost you can use this function to help (Duty cycle works just as good)
Learn Gear: Default is O. It just learns your gears to help with spool and such. I never change it.
Start Duty: You can setup Starting duty cycle per gear. Never use it Duty Cycle works better.
Conclusion: AVC-R is a great tool and is great to have. Its kind of a pain in the ass to use at first but you get the hang of it. If you have owned an AFC it is very similar in how the arrow and keys work. If you have any questions feel free to ask. I hope this isnt too confusing.
