I am tuning boost with my Error correction off or zeroed out, BCLO is 200 and my BDEL is 68 which equals a target of 268 load. Why does my log show a load error of -5 if I hit 269 load (1 above my desired target) with error correction turned off? Shouldn't my log show a load error of +1 since I was aiming for 268 and hit 269?

 

Depends on what load your boost control is following.

 

So it is not following the 2byte? What is it following, Calculated load?

 

I'm trying to figure out something that involves what you are dealing with too.

I know there are 2 or 3 different loads

barometric + temp compensated
barometric compensated
no compensation

I think the wiki that was created here
http://evoecu.logic.net/wiki/Main_Page

lists the addresses for the various loads for various roms.

MrFreds boost control mods thread shows you how to get to the table that controls what load boost control reads.

^ That is correct, but following the 2 byte load makes the car boost really high in cold weather, especially in areas were there is a 30 deg temp swing between day and night.

 

Unless you use a non-additive above base WGDC tuning strategy.

 

Not clear on this ^
I have noticed my logs show that 2 byte load does not change if it is 35F of 90F, but there is a big difference in power. And boost tends to get out of control in the cold air days.
...I use additive above base WGDC because if I don't, WGDC won't recover if it goes above target load and error correction kicks in. I also use Max Total Upward WGDC Correction, set at 3. I use the documented load based mods but still have to tweak tables between the winter -summer seasons (we really only have 2 in Texas). Ill post my tables later for some help

 

Why won't it recover? Do you not have all the Upward Error Correction cells filled in?
