i had someone tell me the avc-r is bad for t2s anyone else experienced anything stupid???

 

Uh. If you like wasting money, go ahead, buy an ACV-R.

But if you like being smart...

AVC-R's (New) are like..600-700 dollars. Used, somewhere around 450-500(Ebay). A used standalone engine management system(EMS-Haltech E6X) runs like 900-1200. Now, lets think about it. A boost controller, or a boost controller/AFM eliminator/injector load adjuster/ignition/A-F ratio adjuster + more..for a little more then a AVC-R? Hmm, hard choice.

 

Ur always better going standalone as for functions and reliability. But the question of cost always comes up. If u cant afford it go with the piggyback, but make sure u get it properly tuned.

 

Waste of money? Depends how much you pay. I got mine for $250 used and it works great for me. Tons of functions, some of which I dont use but it depends what you want. Not all standalones have a built in boost control function, for example my Power FC doesnt.

 

Thats why I only refer to Microtech, Haltech, and Wolf as standalones. The rest just..well I won't get into that.

 

Point taken.

 

There's no problem with using a boost controller on a TII. But if you have a S5 TII, you need to disconnect and remove the stock boost duty solenoid. If you don't, bad things happen (boost spikes, etc.).

 

Well I didn't say it's bad to use. Sure, it will serve it's purpose. I'm just saying that it's not the most cost-efficient thing for sale these days. If you bought single parts to try and make up for all that one standalone can do, well, you'd be paying for like about 2 standalones and you'd still have you're AFM! Lol.

 

If you don't know how to wire or tune a standalone, then the actual cost of the unit is only a tiny fraction of the total amount you will spend. Thus, it's hard to recommend a standalone to just anyone. At least in my opinion.

 

The A'PEXi AVC-R is one of the best EBC's I've ever used.
It's better than the old GReddy PRofec (A) and the PRofec B, IMO.
It's better than the HKS EVC's, but I've never used an EVC Pro before.

I have an older Super AVC-R, and in some circles, these things are priceless - I agree.
The newer AVC-R with the blue screen has more features, but it's "self learning" isn't as good or aggressive as the older models.

One thing the AVC-R does *NOT* like at all is boost creep or spiking.
FC turbos with big exhausts tend to creep - this confuses the hell out of the AVC-R, and it doesn't work right.
This is what most people complain about, but it's not the fault of the EBC...

BTW, the Haltech boost control SUX!

so i have a manual boost controller right now.. im tired of this stupid lag and moving boost limits thang.. and i can get a new avc-r for half the price.. should i? when i boost in 2-3rd gear i dont get the same boost as i would on the highway 12-13lbs is where i am fast anything less and im umm moving but not enough. i want stable predictable boost.. how does the ebc get confused.. and if its not the fault of the ebc. im assuming you are elluding to too small of a wastegate...

 

The current AVC-R has gear based boost settings.
You can run the boost higher at lower gears...if you want to.
I wouldn't hesistate to recommend the AVC-R to anyone.

Yes, uncontrolled boost is due to a too-small a wastegate...

sweet ok now im going to ask too much how does it know which gear is which???

 

i think i figured it out. it compares speed to rev thanks

 

The AVC-R can take a speed signal input.
Amazingly, all FC's have a speed signal input (cruise control - maybe not base models ) which you can tap off of straight into the AVC-R.
This also works for the S-AFC.

Yep, you got it right - speed versus RPM, and it backs out which gear.


-Ted

 

I think you are confusing the AVC-R with the SAFC.

AVC-R is a boost controller
SAFC is a fuel piggy-back

 

Base models have it too. It's in the cluster.

 

i think my speedo gauge is off but only after 100+ i think the cable cant keep up or something
