Yea. The basic problem is that KFLDIMX is met sooner in lower gears because of the speed at which rpms (and boost) build compared to higher gears.

That means that the I component builds faster, and is more likely to hit the I-limit in low gears than in high gears, where it may NEVER get there.

You can also LOWER the i-limit so it is always the limit (and raise DRL), but then you may get interference from the I-limit trims (and other things that affect the i-limit)

That is a double edged sword; on one hand it gives you a way to vary the WG limit based on conditions. On the other hand, its less safe because there are some conditions which might give you an i-limit you don't want.

Again, it depends on how much work you want to do.

The safest thing is to just make the last row of DRL match what you want your wg to be, and bring i-max up such that it doesn't limit your wgdc in high gear


Basically, DRL's effect is gear (and condition) independent, so if that is your wg limit, its easy

I-max's effect can depend on all kinds of things, so if you depend on that for your wg limit, it is a lot more work.

Just make sure to log i-max and before/after linearization wg. Post up them up and I will try to help.

I don't have the names handy, you'll have to look them up.

eheh i meant the logs

Did about 5 revisions worth of tweaking with raising KFLDIMX and lower KFLDRL in the last 3 columns.. I've attached my KFLDIMX and KFLDRL, I ended up with pretty positive results and am hitting 20 psi in all gears except 1st where im hitting about 18 psi, but its tons better so I'm happy with it for now.  Attached is what I ended up with.  I'll do some logs tomorrow.

Looks like you may need to start tuning Q2

start with the RS4 values.

you should tune Q2 for 1-3 in the 4k column, and 4-6 in the 3k column

i.e. if you are overboosting in gears 1-3, raise the 4k column, if underboosting, lower it

then the same for 4-6

The higher the load (i mean, load on the motor, not rl), the earlier (rpm wise) you will hit peak boost.
