The new ATR beta is available for download. Use ATR to update itself.

installed new beta ATR...installed new beta AP firmware...faster resolution is a go.

another new WGDC strategy. with this new ATR, load tuning WGDC is not the same type of guess work anymore. you can now basically command you wgdc and expect your logged wgdc will be ~10% within your commanded....how cool is that!...lol...

after reading the thread posted by Christian, you'll realize that the "mystery multiplier" when working with WGDC is now basically exposed as the WDGC Load & Boost Error tables. You can neutre them as per Christian for boost tuning. Or for load tuning, I've kept the new ATR's values and can actually see the difference in the log, and finally UNDERSTAND the correlation between commanded and logged WGDC....well, in its current iteration anyway...

In short...my last WGDC table is again about 50% of what I need. Since I know I need to hit about 80's to hit my targets, I'll move it close to up there. I wonder if neutreing the load error table will make it easier with less compensation.

back to sq one...but happy about new map to play with.

Hey Fobio, did Christian say the values in the WGDC table are half of what the actual WGDC is? i.e. if it is 40 in the table, the actual will be 80? Or should I be putting 80 if I wanted 80?

Thanks.

Reading the thread, it basically states that the WGDC values are doubled of what you old map is. In reality, this will likely end up working nicely with the new ATR logic. Having said that, THESE ARE DOUBLE OF YOUR VALUES. So eventho it'll likely work out, it's never a good idea to make drastic changes to the wgdc table hoping that you'll hit your targets right away. Personally, I always shoot for under the targets and leave room for tuning up.

do a WOT log of your current tune.... the % values of the WGDC column logged are actual WGDC table values for the 68.25+ (or 75.00+ depending on where you want WOT to be) pedal position in the beta ATR

with the new beta ATR, WGDC is no longer a variable in a linear equation.... WYSIWYG :)

Awesome! Yeah, I did a log last night w/ half the WGDC values and I was only hitting 13 psi while targeting 17 psi. Looks like more work to do!
