I had a BM3 stage 1 map in but I pulled it and went back to stock and clicked the option to relock the ECU. If I want to put the stage 1 map back in will I need to go to a tuner to unlock it or is this something I can do from home? Thanks.

I flashed the car (M2C 2019) and is working EXCEPT:

1) GTS roar is not working.
2) Cold start works once a day, and done.

I tried just flashing a new OTS map with only GTS roar enabled, and nothing.
I then changed the config to this and still nothing:

Did you fix it? I have the same problem here. My M2C sometimes does have GTS roar, but most time it does not. I flashed Stage 1 91 Octane with GTS TCU.

I went from stock to stage 1 this week w/ startup roar and generally *very* pleased with the reflash over factory.

It's quite smooth *most* of the time but I get some hard jerking with consistent part-throttle acceleration in sport+ through 2nd gear fairly often. Happens a little bit downshifting from 4th -> 3rd too. I've read about this on DCT cars but i'm a 6MT, so i'm a little confused. If I lift off and tip back in it usually just goes away. The herky-jerky in downshifting feels weird but it's more an annoyance than anything.

I searched around but didn't find much for manual vehicles.

The "herky-jerky" you are feeling is typical with all manual cars, regardless of make, when your clutch/gas timing is a bit off. You just made a significant change to the car's tune - it is essentially a different car now. So it may take a little while for you to get your timing back, but there is nothing wrong with the tune. I have a 6MT (and have been driving manuals for 25+ years) and saw the same thing until my footwork timing was "re-calibrated" so to speak - but it didn't take long. Now everything is smooth the way it should be...

I think my above question got burried in the new PTF software frenzy so I'll just ask again so I don't have to start another thread:

If you flashed to stock and relocked just try to flash back to Stage1. BM3 shouldn't have "hard locked" it.

So I just got my BM3, and in searching all the ACN91 tunes, I see different versions and release dates.

Which is the one I should go with: most recent version, or most recent release?

The MultiMap is newest, contains ACN91, 91 and 93. Go for it.
Try the free GTS map too.
(Consider a hub fix above GTS)

I'm assuming a Stage 1 ACN91 would be considered above the GTS map? I am planning a hub fix, likely when I go FBO + E85. My car is just a daily driver, so I'm hopeful that'll mitigate any risks when driving.

Yes, the Stage comes in much harder than GTS.

Top!

In reference to the Multimap (Stage 1) -

> Map1: ACN91 octane
> Map2: 91 octane
> Map3: 93 octane
> Map4: CS stock power map

How does the 91 compare to the CS Stock power map and how does that actually compare to the separate Stage CS+ map?

The first 3 maps are Stage, so a big increase over stock, and with a kick like all Stage maps have. Stage1 is about 18/20/22% over stock HP/TQ for ACN91/91/93.

The 4th CS map is probably the same as the single OTS map. CS is a linear map without the surge, like the Stock map but a little more (5%?) power but more even application. GTS is slightly more power than CS but the same linear application, so GTS is a favorite of mine.

So stage 2 map is for rides with downpipes, chargepipes, full exhaust?

You can run up to Stage 2 with NO bolt ons at all. Totally stock. Bolt ons are "recommended" to hit "published" power levels. The 2H will even work with stock turbos, but top them out early.

Just watch your hub above GTS power. You do the research and pick your risk/fix ratio. I did the hub fix+CBC so I can play without the worry.

I have the CBC and I am on stage 2 OTS now.

Do you run the Stage 2 MultiMap OTS?

No I haven't put that one in yet. Didn't load it cause I need to order the Zeitronix

Thanks!

Ok., I mentioned the, "separate Stage CS+ map". According to a post (by PTF ?), a while back...

[FernieAriel]

Does anyone get great burbles on stock exhaust non-comp? I dont have any, unless I'm parked and I rev it, or if im slowly driving downhill, in those two cases only I hear loud, distinct burbles, the rest of the time, nothing at all.

Agression set at 5 for both modes, 2.5 seconds for both modes, min rpm all the way down and max all the way up, nothing.

Is the only way to get burbles to get a DP? They're perfectly loud when they do happen now, but the problem is that they don't happen most of the time.
