Attached is a the log , the temps today were in the 90s but same result even in the 60s

Can you post the full log url?

Honestly looks like a boost leak to me, even though you've done a bunch of smoke tests. Your boost pressure deviation increases in a pretty linear fashion inversely to your pre-throttle boost dipping

I honestly Don't even know where to look at next my next move was to get a compression test done and to replace the wastgate .

This is the last message I got from the tuner.

There must be a reason that the turbos are unable to properly make boost. Your WGDC is 99% most of the time which means the wastegates are fully closed but you are only making 16psi up top.

A little real world data on what this setup can do. MDM on and cutting throttle while tires spinning. Done on 285/30/20 PS4S. Can't wait to see what this setup can do with at least some traction!

Edit: oh yeah, no meth, no PI, stock motor. 👍

Movin! How much boost and is this E85 or a blend still? Jealous of that linear acceleration curve there with DCT too!

TopJimmy · 06-23-2022, 10:38 AM

Those wild power curves when I used to shift my manual F80, that drove me crazy!
I surely can appreciate how to launch and shift a manual at limit…but God bless the DCT for doing it so well, consistently.

Look at this wasted time hand shifting

It's moving alright! This was E70 ish. Boost, honestly not sure.

SPL rear toe links with eccentric lockout + alignment next week. That should hopefully knock off a fraction. Then Wagner front mount heat exchanger next month. Will probably throw in on the dyno at that point to see what it's making and do some final fine tuning. Maybe that will get me 5s, but traction is the obvious limit here.

E85 and sticky tires will be 😳

😱That's definitely a chunk of time alright!

This DCT with xHP stage 3 is something else. So much better than my E92 M3 DCT. Those wobbly curves in my run are tires spinning/MDM cutting throttle. With a good hook and DSC off that thing will be a straight like. 😅

astris · 06-23-2022, 12:27 PM

This thing is crazy consistent too. Runs all seem to be within .1 second ish of each other with the difference just due to slope.

Haha yes, absolutely. This graph is me absolutely slamming 3-4 and this is literally the best I can do. Maybe with the CDV removed and a short shifter it could be a tiny faster but the real killer is building boost again after the shift

On a somewhat related note, rolling anti lag is a blast. Only tried a couple times, but the hit feels like you take off more immediately than a NA motor.

Easily my favorite feature of the car. I'd like to have a touch more than 15psi on tap on the initial hit, but maybe when I get retuned and such.

My F82 "Shirley" is back from BMB Autowerks where Version 2 has been applied:
- Custom E85 map by Paul Johnson Tunes
- ID1050X added to my existing EOS
- Rebuilt by me Fuel-It Stg4 LPFP (filters)
- BMB custom braided Teflon -AN fuel lines
- FueLab dual feed fuel filter @ 6 microns
- FueLab bypass regulator at 100PSI
- BMB custom fuel return into factory line
- Motiv Reflex+ and Aux1 to the LPFP #2
- Snow 2.5 braid kit with PodWurx mount

After just a base map and one revision I was approved by F80Paul to go log runs at the dragstrip. I was happy to start off a Friday night with a new 1/4mi best time of 10.369 seconds and trap speed of 141MPH! Previous tuning on E40 topped me out at 10.400 at 139. Paul usually does many careful revisions so I expect to hit 9.99 soon.

I'll start a new thread since I'm now outside the scope of this thread (turbos+EU5+lift kit).

astris · 07-16-2022, 09:34 PM

Still on stock size 285/30/20 Michelin PS4S and of course no meth, no PI…

EU5s, Dorch HPFP lift kit, PR Stage 3 Brushless LPFP. No meth. No PI.

Just ordered some R888Rs. Can't wait to see what this thing can do once I actually have traction!

Niceee!! What RPM were you shifting at?

Redline. 7000k-7500k takes about .25 seconds in 3rd, so not really much time to be choosy. Lol.

astris · 09-15-2022, 10:52 PM

Finally got it on the dyno.
