Avcr Settings, Dropping Boost

[Buddy92]

Gday.

I bought a R33 around 2 weeks ago, and it has a AVCR in it. Is anyone able to let me in on some settings, and/or tips for it? I cannot seem to get it to hold boost, it boosts up to 0.90, then will drop of to as low as 0.60 through the RPM range. There is no reputable tuners out here to take it to so was hoping someone had a little insight on what to do.


I have watched countless videos and read countless forums post, and still can't get it right.​​

Anyone? Starting to give me the shits

From memory no 'gain' setting on avcr, only target boost and duty setting. If your target boist is right then bring up duty cycle a couple of perecent at a time. Turn off gear-based duty until you have stable boost then fine-tune it.

Also from memory avcr has rpm-specific duty settings? Increase duty in areas boost drops off.

You are on the ball! It was dropping off at a certain RPM so I changed the duty at that RPM and now it is holding through every gear equeally.
