I've read quite a few threads regarding people experiencing problems with the Apexi AVC-R. These problems include among other things: a ticking noise made by the solenoid, boost spikes, too complicated, and failing to hold high boost levels consistently. Although the AVC-R / S-AFC combo is aesthetically appealing to me, I don’t want to regret purchasing and installing these units.

I plan on staying BPU for a while and it is my understanding that “fuzzy logic”, as used by the AVC-R, is not ideal for sequential turbo setups.

Although I find the AVC-R aesthetically appealing, I have a few questions in regards to its functionality:

Does the fact that the AVC-R uses “fuzzy logic” make it inferior for sequential turbo setups? If so, is there a way to disable the “fuzzy logic” capabilities of the unit?

Will disabling the AVC-R’s self-learning mode prevent the unit from using “fuzzy logic” all together?

Will disabling the AVC-R’s self-learning mode make the unit compatible with a sequential turbo setup?

What features are lost in disabling the AVC-R’s self-learning mode?

Will the AVC-R reliably hold as much boost as any other electronic boost controller on the market?

Thank you in advance for all of your help supraforums.com!

You can disable the learning mode, many people on tt.net perfer this...

With the self learn off you can adjust the boost curve by RPM to fine tune it, it's feedback speed, and start duty for the boost in each gear, either negative (for traction problems) or positively...
I don't think you lose any features with s/l off, and as for its complexity, its not too bad if you fiddle with it for an hour or two... I personally think it's great, graphing mode, replay 4 channel monitor.

Sounds like I am in the same boat you are in.. I love how the APEXi units look, but I would rather get another controller in order to do the boost more reliably....

What do you guys think of the new Blitz conroller... or should we stick with the HKS ones...

from what I understadn about the evc-ez (or whatever the name is) you basically set the boost and setup a high and low setting.. done...

then you press a button for each setting?

Correct???

No, the EZ has a knob on it and an on/off switch. Thats all it has. You have no settings you just turn the knob. Kinda hard to get it exactly where you want it to be but it holds boost well. Its about as plain as a manual boost controller, ZERO features.

HKS EZ is the way to go. I had AVC-R before...too complicated for common guys like me who just wanna up boost. its basically an electronic boost controller, and it does have the most responsive step motor on the market....I'm getting all the boost I ever wanted with simple turn of the knob. EZ.:D

I second that. I thought the clicks were terrible when I got mine installed. After a car wash, the clicks became 5x as bad and solenoid duty only reaches 90%.....
