Yea I think its one of the best things of this platform. My new vanos tables are working great btw

Cool ! You make me want to focus on it soon (I admit i am a bit afraid too to make something bad for the car.)

2-3-4 pull with the new 8.1 1+ (Fresh Turbos, Coils, plugs, VC & VCG)

https://datazap.me/u/olivier/new-81-1?log=0&data=3-4-21

Feels definitely fast (faster than any 1+ on previous version), a little bit worried about timing correction (esp Cyl 5)...Never had a carbon cleaning, might be related

Cylinder 5 here the most carbon build up out of all of em. So most likely. You should blast your valves

MHD advertises this tune as "using a peak of 14 to 18 PSI tapering to 11-12 PSI at redline". Looks like I hit about ~17 peak and ~11 at redline so I didn't think too much of the actual boost vs boost target discrepancy. Then again I'm really out of my element here lol.

I decided to try RFP's stage 2+ map for 93 oct liked it a bit more than V7.1 stage 2 from MHD, I used an E20 mix with my local 92 oct pump gas, this seems to have cured the timing corrections on all my cylinders I guess that is a good thing, but why am I not hitting the target boost? I don't think I have a boost leak as WG Duty cycles seem OKeish to me, can a custom tune definetely help or my setup is maxed out? I'll try his E40 map next week, hope my LPFP can cope if not a stage 2 bucket is on the way.
Thanks for any help.

With any OTS tune, its going to taper up top, not hold flat across.

Even though your target is higher, its not going to follow it all the way to the top. MHD usually just tapers the target so it doesn't look like its missing it, RFP leaves it higher for some reason.

I would say yours looks fairly normal, but you could have a minor boost leak somewhere. As id normally see boost and target meet at every shift when you're shifting that low. Any codes?

does look like a boost leak or just tired turbos / wastegates.
You are barely able to hit a load 150 above 5k rpm (that is low)

Thanks for all the help! really digging the RFP map, I don't have any codes or anything weird, last week I logged on this exact same map and boost seems better as it at least meets the target, altough last week I only ran pump gas and got several timing corrections. Only changes this week were E20 mix to see if corrections dissapeared (they did) and I logged on a much higher place than before ( 7939.633 ft vs 8923.885 ft) don't know if the high altitude is making the engine choke and therefore boost and load are not met?

Thanks for the heads up! don't know if the altitude of my city is robbing me of that power and making the engine choke? I live around 7900 ft above sea level

Oh yeah, that explains it.

You cannot use ots maps successfully at that altitude, you need a custom map.

[Sgop335]

Yes it does, should have seen the ambient pressure

That was the consensus the last time we spoke, seems like I have nothing more on OTS maps, either RFP or MHD will go custom then! thanks for taking the timeand looking at my logs

it was 10.8 and 11 PSI on those days if that helps

Seen that some people were running RFP here and just want to warn you, that be careful if you still have secondary cats with his V12 beta map, he said on his FB post that he added fires only for stage 3, and it's not true, it's added on stage 2 bin files too.

I ran it for 20 minutes and found it weird that it was doing aggressive burbles without checking them on MHD flash options...

[924er]

Dumb question, do I need to let the car get used to the map for few pulls or a few days before doing a datalog? I just tried v8.1 map but same map and there were timing corrections on all cylinders.

Just wanted to FYI: The MHD OTS V5 E40 map does not taper, from reviewing my logs it targets 21PSI across the RPM range

Did he build that into the tune? I might have to check it out and run some logs.

That's any v5 map, I guess I meant any current map

He started tapering the commanded boost so people didn't think something was wrong with their cars when it didn't hit target

Yeah thought it was strange he never mentioned it being added for stage 2. I never ran it, i just looked over the maps.

It's added if your using stage 2.

Yes, only in Stage 2 & 3 V12 beta maps. The problem is that he said on his FB post that he added "fires/flames" only in Stage 3.
I flashed Stage 2 to test and realized that it had agressive burbles but at first I just thought it was burbles like MHD burbles.
The problem is that in reality it was the flames/fires feature from the stage 3 ( up to -30 timings on the main timing table) not cool since i am still running my secondary cats
Just look at the timing (main) with TunerPro.

I ran it for 20 minutes so i hope it didn't damage cats.

Car is JB4 catless dp only and was super fun and fast before I updated the firmware on my jb 4. I did spark plugs and coils cuz of misfires before the update. But now the car seems to make the same boost but feels super slow and underpowered. It did throw a couple of codes but nothing for boost or any concerns.
