904MK7's self tuned build.

[Diggs24]

No im saying make your first column 0 and second 815. Now you can fine tune with the entire right side. Make every column like 400 more than the last at lower boost then narrow it up top. 800, 1200, 1600, 2000, 2500, 2900, 3000, 3,100, 3,200. Something like that.

Ahh, I get it. Thanks! I'll try it!

Took the mighty diggs advice and changed the axis. Lets see how this does.

wut, no

What am I missing? I am keeping wastegate closed until I hit target boost.. @Diggs24

 

[904mk7]

I changed the top to start 400 up to 3200. It looks crazy, but I have wastegate opening at 2700 boost pressure at 4k

what happened to all this? You still need to recreate it. Take 3000 rpm for example. Now it is all 0s???

I was setting it based on when my request was starting to go up. Made some adjustments. I'll see how it spools today. Thank you!

Of course I fix my wastegate issue and my tablet died. Good thing it didn't die while flashing and I had everything backed up, so all is well. New laptop coming today. Hopefully I'll get some logs tomorrow morning. From 40mph in 3rd boost seems to peak at 4400.

Well, I'm an idiot, but this week was a good week car wise. I finally fixed my gas tank issue and realized I was reworking my wastegate map backwards. I didn't realize that -0.0001 meant 0% boost. I thought it mean wastegate is closed. I would plug in numbers like .25 and .45 which I thought meant wastegate opening 20% no... It means 80% of the airflow is diverted through the wastegate, so no boost. Either way it spools quick AF now.

That was way harder than it needed to be, but got it. Peak boost at 4400. Dropped it almost 1k rpms. Going to shoot for a little more earlier and fix the shift spike again we will be good. Ran a 10.20 this morning at it was 77* out. My best time was 10.01 when it was 58*

Finally got the car dialed in, but heat and humidity have set in here in Florida. When I got my 10.01 is was 62* with almost no humidity. Now it's 77* outside in the mornings with 85% humidity.

These two runs were two separate wastegate changes. Only difference was one was uphill and one was slightly down. Ran identical times though. I'm happy with that. None of my runs have been with brake boosting btw. They have all been foot to the floor in 3rd at 50mph.

 

[904mk7]

I just compared my fastest run to my run now. In the same temps I'd hit mid 9's no prob. Heat and humidity killed the recent run top end. Thanks to everyone that helped @Diggs24 @arob157

 

[904mk7]

New datalogs. Overshot a bit in the meat of 3rd, but otherwise solid. I'm not even going to bother to do dragy runs now that it's 80* in the morning with 93% humidity.

Datalog from this morning it's 75* out and 93% humidity.
