Starting sets for GM 3-port solenoid ?
What do you think about starting sets for Evo8 with full 3" TBE, walbro and stock other. I want see 19.5-20.0 boost flat.
What do you think about target = 230 (80+150) and MWGDC = 100 for 500 - 2500 rpm, 75 for 2750 rpm, 50 for 3000 - 6000 rpm, 75 for 6500, and 100 for higher? Thanks.

Every car is different. You are probably going to have to rock some trial and error either way. Methinks its best for you to half your values, make appropriate adjustments, and work from there. It can't hurt to guess low, but it can go boom if you guess high....
Don't forget to zero out your max boost adder v TPS table and keep an eye on any corrections the ECU is making.
For reference... I started out with 40% across the board since my AEM BCS was running 52% off of the Tru-boost controller and slowly tweaked the rest of the map as necessary. Sometimes adding 1 or 2% can make large leaps, so take your time when you start getting close to your targets.

tephra, I thought you worked out that table had a 2% resoultion cabability.
Thus there was no point in increments of less than 2.
Or I have a (very) bad memory...
I like the scaling setup, was wondering how you were doing that.
Presumably that scale is not used by any other routine?

If you zero out the 2 values that this table has, you will essentially turn off upward WGDC correction higher than your WGDC table values. So with this method of boost tuning, you have to make sure to tune for a higher WGDC that would be enough for your desired boost level even in hot weather. And correction will reduce it for you if it's too high. But you'll never get a WDGC higher than what is in your tables. Only up to those values. At the same time it becomes easier to use positive correction values and reduces boost spikes. So you trade off one thing to gain another.
I personally have either 5% or 3% there.. Stock is 10%.

Definitions are posted somewhere here. A quick search and you'll find them.
