Valvetronic threshold BM3 OTS Stage 2 map

[ArmenLS1]

Recently flashed stage 2 OTS multimap and was running the 93 octane map. I knew the car wasn't pulling as strong as it could. Didn't get ant CEL's or messages on dash. I haven't logged yet. This code did come up. 1355501 Valvetronic threshold. Only mods are AA DP on my 2021 with 8900 miles. Is this a common thing or something maybe people are getting with the new 2.5 version map?

Try reflashing the map

What version OTS 93?
A few have had issues with 2.5.
I've been on 2.4 for ~1year, super smooth.

 

[ArmenLS1]

I'll clear the code first see if that changes anything. Then refresh. I wonder if there is a way to access the old 2.4 or 1.1 multimap.

 

[ArmenLS1]

In addition to this. I also just realized from the 1st code that I had started the car while it was connected to a battery tender. It was in float mode at that time. Clearly the computer realized that, hence the shadow code. Is that cause for concern?

The only version of the OTS multimap is 1.1 . The stage 2 93 octane has a 2.5 version. Unless I’m overlooking something on my bm3 app.

I think the previous multimap was vs 1.0, my bad

So far I have cleared the codes, went for a spirited drive and did a few short WOT runs, code didn't come back. Car felt better and when I came home I did not see the code again. Viewing my logs right now. Which specific paramaters should I keep my eyes on?

P.S. the Power management: external charge detected code came back as an inactive shadow code even though I haven't had the car on a charger. What is that??

Already sent a log after clearing the code to PTF, and one of their guys said everything looks ok.

Anyone else able to take a quick peek at my 4th gear pull? I apologize, the log is long. Midway there is a 4th gear pull that can be singled out and viewed.

Stage 2 Multimap - Map 3 = 93 octane, 2021 with AA DP. t/c and vsc fully off.

It's hard to get anything out of your long log, but you have several error codes (Torque Limitations 4,8,128).
see here :

And - you probably don't want to hear this - 2 knock detection.
You will see them by marking the "Knock detected" and the "Ram Torque Limit" flags.

I only found one part that can be evaluated with WOT and that is in 4th gear.
Depending on your weight and fuel tank you'll have around 470-480hp at crank.
That is similar to an MHD Stage 2, so your car has enough power ;-)

@kfer
Much appreciated! I did see the 2 knock detections. They are very random and not during the WOT run. Kind of at a low rpm and low to mid throttle. Maybe it picked up some sort of vibration or triggered something at lower rpm? 0.04 knock at 1050rpm. Possibly not real knock?

I don't know, it definitely sounds strange. I don't think its LSPI but I've never seen anything like it.
You start driving in 1st gear, and immediately (speed = 2 @1173rpm) you get a knock and the strange torque limiter code (128), and it stays there even after swith to 2nd gear. At that point begins the ignition corrections too.

 

[ArmenLS1]

Could this be the car just learning the new tune? This was recently flashed like a day or two ago with minimal driving. I'm thinking back to my days logging with hp tuners and Hondata, the numbers here negligible. Unless they are concerning in the German world, ja?

But I really appreciate this break down!!

 

[kfer]

What are your mods ?
Any TCU tune ?
I can imagine, that it needs a little time to change the adaptations - but I’ve never experimented that.
You should maybe try to reset the adaptations at least for knock detection and octane rating (don’t touch the throttle!).

 

[ArmenLS1]

Only a AA catted downpipe and lowering springs. Everything else stock. No TCU tune.

EDIT: Only other thing I can think of is if it's related to my evap issue. No leaks, just an issue with open circuit on the pressure switch. Spoken to many tuners and mechanics, all said it wouldn't effect car performance only mileage. I guess i'll try to chase that issue.
