Avc-r Or Profec-e

[medi_evil]

hey dudes just wondering, I have mate who wants to get a boost controller but isn't sure what to get, its a toss up between the AVC-R and the Profec-E.

so just after opinons an which is better or not etc

cheers matt

Blitz SBC ID3

oi i was gonna say the blitz sbc id3

or u can also go the hks evc iv

seriously, go look at the information for all of the mentioned boost controllers, then see which one suits u, and u like the look of, depending on price also, u can also get the ricey sbc color.

meh.

so u reckon they are better that avc-r or profec - e?

AVCR has closed loop PID boost control, you can even change duty cycle w.r.t RPM - WOW just like every boost controller should.

Yeah and despite those features they are still a pain in the ass to use and still dont hold boost better than a decent bleeder IMO!!! Go the Blitz...

What about the Hybrid 2-stage electronic boost control?

Has anyone got anything good to say about that little gadget? I bought one simply because it was a good 'cheap' price for a EBC.

the HKS EVC's are the best on the market

[Maxx]

but the HKS EVC don't have "gain" function, go Blitz

[R31Nismoid]

id prefer my boost to be held better

[medi_evil]

but the HKS EVC don't have "gain" function, go Blitz

which 1 have u got the idIII or the new colour 1?

and have u got all the extras like speed meter etc or just the ebc

...i no longer use an AVC-R, but did for 3-4 years with both the std turbo and a Trust turbo. The thing worked extremely well, never spiked, held stable boost. I was vert happy with it.

There have been several instances where ppl claim they have not worked...i just cannot understand how this can be the case. If you understand how they work (which aint rocket science, just read the manual) then they are even easy to setup. The instances where they have not worked 100% have usually been traced back to not being installed correctly, with wrong diameter hose, undesirably long lengths of the incorrect diam hose etc, its debatable whether any EBC woudl work optimally if installed in the same manner?!?!?!?!?!?!?

And they are a very flexible EBC, and the variabel duty cycle works very well as my std wastegate presssure is 0.65bar, and with the AVC-R set to 1.25bar it held boost just fine. So thats 9psi to 18psi and it managed to control boost. Others seem to say that its very difficult for an EBC to increase boost so much beyond what std spring pressure is, AVC-R did it.

Who gives a shit about a gain function when there is a PID loop trimming the boost to the desired level. This is how the autronic boost controller tables work and it is well impressive.

What you really want is a boost MAP, RPM vs Load just like any fuel or timing MAP. This way you can eliminate the wastegate cracking to early.

I dont think you can compare a bleeder vavle to a ebc. ie if your wastegate spring tension is 8psi and you want to run 15-20psi how is a bleeder going to hold the boost further along in the rev range when more and more pressure needs to be bled from the actuator?

If only everything was linear eh..
