Dano's Boost Tuning 101 + Cool Stuff

^I thought the value that you set was actually lower than the wgdc you see in datalogs?

So wouldn't 30% on the wgdc table be closer to 70% (going off of dano's 2x+10 figure)?

Or you're saying that you have it at 30% in the datalogs? Which would be ~ 10% in the appropriate tables in ATR?

sounds like you just need to lower WGDC some more in the RPM range where you spike.

you want as little WGDC as possible and still achieve boost targets. If your WGDC is too low then the ECU will use the Boost Dynamics table to add DC and try and achieve target. So you want to keep the table values as low as possibe.

No, sorry, my values in ATR are 30% up to 6000rpm where I backed it down to 28% I haven't had a chance to get a clean log yet. I guess I'll just really drive them down and start from the beginning

I getcha, I was just thinking if you had roughly 40% values in ATR with your K04 that I'd start with 30 but it appears that wasn't low enough still.

Well unless you are in Australia [don't think there are any Moose there LOL] it is winter and WGDC values will be lower now than if you were tuning in the summer. Once you get them correct for now you may want to try and add like 2 or 3 to the values so there is room for growth as temps rise.

This however, may induce boost spikes post shift though if you raise them around a shift point. if you do then put them back and just know as temps rise you may need to increase them.

Setting them just right for now may work if the Boost Dynamics table has enough room to add to them when temps rise.

Thanks mang, I'll just start them all off lower and work them up slowly. Oh and yeah... I'm in MN so today we're looking at 11 degrees.
