So I am running a stage 2 ots with sf cone. My ltft idle and cruise are all within 1.2% +\- my boost is only reaching 22 on lwg but is spiking 28 and getting 3 counts of knock on regular tune.

I have been reading and reading and it sound like from the accesstuner "how to" that all I need to Sonia lower the boost control load offset to lower boost in general.

But then when I read about other threads I get conflicting opinions!!

On my VIII I used a hallman set my boost to 26 psi
Then logged and used a rpm vs load reference to tune my Hugh octane and low octane maps as well as timing to meet afr. This was EASY lol
The x's are throwing for a loop on this accesstuner thing! And using te ecu for boost

 

Bump for postin in cobb section

 

OP, If you havent got this sorted out, lets see if we can get you squared up

 

I'm still open for some info

 

I would rather run the 93 normal waste gate and just turn the boost down to the 24-25 range

 

I'm interested in this as well. My car has the same symptoms. Stage 2 ACN non-lwg map spikes to 28.5 psi but then settles to a nice curve up to redline. I was able to eliminate knock count by taking out timing at the affected rpm-load areas, but i would still like to lower maximum boost to 25-26 psi as well, but not by using the boost offset parameters, because that would effectively lower the boost curve over the whole rpm range. I just want to reduce the boost spike I see at around 4000-4500 or so RPMs.

What you need to do is use accestuner race, go into wgdc reactive, and adjust your levels and then test it out. I would do some research on it before attempting it tho. Read merlins guide to tuning evo x.

 

I've read more and more and I'm learning that I'm gonna have to adjust the wgdc to control spike only thanks.
