I bought my AVC-R used so it came with no book. I went to http://www.apexi-usa.com and downloaded the AVC-R manuel which was about 60 or so pages, but all it explains is how to get to every option by pushing the buttons. It gave no definition to what things do or stand for. I'm sorry but this thing is complicated and I am not electronically inclined to mess with this. So can someone please describe to me what these options do, and how should I use them!
1) Boost Duty
2) Scramble
3) Ne Point
4) F/B speed
5) Learn-Gear
6) Start Duty
7) Car Select - if someone knows what setting it should be for a '99 Si it would be greatly appreciated!
8) Sensor Select
9) Gear Judge
10) Graph Scale
11) Sensor Check
Sorry, but seriously I do not know or feel comfortable with messing with this without knowing what this stuff does! I am going to finish installing my wideband tomorrow and hopefully get dynoed on Friday so your help will be greatly appreciated! And if you are wondering the person tuning my car mainly deals with domestic's, so he does not know either.
Thank you for your time!

 

i would like to know too.........TTT

 

 

Ok, I know this isnt what you want to hear... But everything you could possibly want to know is in the manual online. The online manual is the EXACT same as the one you get in the box.

The AVC-R is SUPER easy to use, once you figure out the vocabulary.

If you have a more specific question I will gladly help you. But I am not going to write an essay for each thing listed, since they are all in the manual.

 

My advice after months of beating my head over the AVC-R.. tune for one gear (I use 3rd), then adjust the other gears in coordination with that gear.

Paitence is key but rest assured, the AVC-R will learn..

 

i believe the scramble boost option is for the orange wire on the harness. if you hook it up to the ground that the AVCR is hooked up to and run it to a switch you can press the switch and add a certain amount of boost to what you are already running. When you set it up on the avcr you put in the amount you want to boost on top of what you are already running. You can set it up for a certain amount of time too. Example: You are running 8 pounds press your button and you jump to 12 lbs, this will last for 20 seconds. I hope this is not to confusing.HTH

 

 

Ok im going to try to give a rough break down of this. I'm at work right now and dont have my car to look at, so if i am wrong please correct me. Feel free to add more info to my little list:

1) Boost Duty - BST sets how much boost you want to run. it is in kg/cm^2, conversion of this to psi is 1 kg/cm^2 is 14.2233439psi. Do not confuse this with 1 bar, which is 14.7 psi. The duty cycle is in %, you have to mess with this to get your desired boost. Say you are running .55kg/cm^2, then a good number to set your duty to is about .4 to achieve about 7.8psi. The higher your duty goes up, usually the boost will go up

2) Scramble- i do not use this feature, but what this does is toggle bw modes A and B without having to mess with your avc-r and run through a couple of screens.

3) Ne Point - This mode allows you to set the boost to the desired RPM's. RPM's less than the lowest point use the settings for the lowest point, same for higher than highest point. In my prelude, i believe, use from 3000 up to 6500 in increments of 500 rmps

4) F/B speed -This is how often the avc-r checks the boost and corrects it automatically. If you get boost spiking, try decreasing the numbers for the gear you are spiking in. I have mine set at 3 for all 5 gears.

5) Learn-Gear - This is basically having the avc-r learn your gears and have it boost accordingly to what it reads while you wind out your gears. I like this option, however some people dont. Its really just a matter of preferance, I believe O is on and X is off, just mess with it and see which settings you like more.

6) Start Duty - This basically can control how fast you want your boost to spool up in a ways. It plays a large part in boost spike also. The more you increase the more you will spike and spool quicker, the more you decrease the less you will spike and slower you boost. 0 is a good initial setting for all 5 gears until you get comfortable with the controller and want to tune it to your likings. This correlates wtih the NE points of the gears you have, it will basically controll the boost for the given RPMs that you programmed into the NE points.

7) Car Select - 4CYL, 4SPD, and have the arrow pointing to the upper right of the LED screen.

8) Sensor Select - Relative 1

9) Gear Judge - The avc-r will read out a number (N/S) while you go through each gear, the average number that appears on the screen is what the gear judge should be set to for that individual gear

10) Graph Scale -1.0kg/cm^2, NE=rev limit, SP:=top speed of car, usually 180-240, check your dash to see what it has in km/h

11) Sensor Check - this will just throw out voltage values the avc-r reads, you dont gotta mess with this.

I hope ive been somewhat helpful, feel free to email me with any questions. Good luck!

 

Well, after reading that, i'm skeered to touch the AVC-R, though i have heard a million bad *** things about it.

 

don't be. It took me all of 30 mins to have it working perfectly. It helped that I had a V-afc, so I knew the interface.

here were my initial settings:
boost 1.00 duty 56%
ne point 3000, 3500, 4000, 4500, 5000, 6000, 6500, 7000
feedback setting 9, 8, 6, 5, 4


first follow the instruction for the learn gear, so it knows which gear you are in.
then, Set it to the above (change full boost to what you want, say .7 just intially).

Don't set multiple boost levels on one map (now). Just make it .7 accross the board. Also don't change the duty cycle.

just do a few WOT runs in through 3rd gear, and on the boost/duty cycle setting screen it will say "**" instead of "56%". That is when you know the computer has learned the boost curve.

Once you have done that, you can adjust the boost level as you wish (even change it for rpm).

No man. The Start duty just helps you create or control boost spiking. For me, I have 1st gear at 39% so I can get 17psi in 1st gear (normally there isn't enough load), and ariybd 1-10% in the other gears.
you set it for a positive value to increase thespiking, and a negative value to decrease the spiking. It works REALLY well. This is an AWESOME feature.

to control spool up, go to the boost/duty screen, press "NEXT" and raise the duty cycle on the lower rpms. THIS will make it spool fast.

Thank's everyone for the helpful info. Honestly Turbointegra, I did download the 60 or so pages and printed them out, although I can't seem to find the binder right now, but to me it did not give a definition of what the functions do! It just explained how to get to each function. I could be wrong, but I will look again as soon as I find it. Thank's again everyone and if anyone else want's to contribute there skills on the AVC-R, it is greatly appreciated!
Thank You, turbo Si!

 

Thank you everyone for the helpful information. Honestly TURBOINTEGRA, I did download and print out the manuel off the net. All it explains is how to work your way through it and get to each fuction. It gives no definition of what a function does. I could be wrong although I will look again as soon as I find the binder I put it in! We'll again thank's for all of your helpful information, and if anyone else would like to share there skills with the AVC-R then please feel free to do so!
Thank's, turbo Si!

 

beat me too it. everyone has contributed almost all that I could say about it. i gotta check my settings when i get home and let ya know.

dont be afraid of it though.

 

Let me know what you come up with!

 

?

 

Anyone else?

 

when i get my avcr on monday and learn to use it, ill tell u wassup. Im confused myself, but it does not seem that hard to get used to once i get it in my hands
