1) BM3 final tune, put 385WHP
2) Stock Tune does 320WHP
3) Back to same BM3 tune, 420WHP/465WTQ

I don't think any of these numbers are correct. The last dyno I had on this same machine about a month or so ago was on a lower boost tune with a misfire on one cylinder and it made 416WHP. This current tune feels WAAAAY stronger, and I know is making significantly more boost. I looked at some of the logs I had from the runs and it looks to me like the guy 'driving' didn't know how to get a solid pull in 4th without a kickdown so he babied it a bit too much.

I pulled a few times against a stock Camaro SS (455HP crank) later in the day and we were pretty much dead even, but then got whooped by a 335is that claims only JB4 and catless downs. Logs look OK to me, but I'm no expert (clearly) otherwise I wouldn't feel like I have no idea what's going on.

How was the battery when you did the dyno? If for whatever reason it was exhausted you're losing 50Nm or 37lb.ft and probably about 35hp, which is exactly what you've got between 1 and 3...

The AH3 is not easy to Dyno. I think you need at least 3 to 4 runs to have a good idea. My numbers last week went from 345 / 440nm to 353 / 513nm.
All with +95% battery.

I tested against a m135i manual and m235i 8AT with both JB4 and downpipe and it was a draw.
Do you have a dyno graph?

Here are my numbers:
Stock 323 / 397nm

Stage 1 Flash tune: 397 / 578nm

After two weeks: Went in limp mode several times, so I went back.
They restricted the torque. Don't know the numbers.

After 4 weeks: Went in limp mode a few times again, brought the car back, they restricted the torque again. Didn't know the numbers untill last week:

Dyno last week (after 8 months): 353hp / 513nm

I'm not happy with this last dyno result. I'm now going back to my tuner to have the 397/578 map activated on Sport+.
In this case I don't think I will encounter any limp mode errors, because I barely drive on Sport+. And if that's doesn't work I'll also try BM3.

Kickdown is a problem on our cars, even in Sport+. I'm ordering the BMS Kickdown blocker.

However I think the 5th Gear is the correct Dyno gear? Or at least that's how they do it over here.

Will keep you posted!

Yeah, kickdown is a bitch. I swear "Manual" mode is just slightly-less-Automatic mode (as it kicks down and shifts up without me saying). I have the blocker, so I'll put that on next time. We did the pulls in 4th, so maybe 5th will be a better option next time. We also did them in Sport+, you think there's any benefit to using DSC off and manual instead? I don't like to drive that way on the street because I lose the tighter steering and suspension, but on a dyno it shouldn't matter.

I'll ask for the graphs, but they aren't much to look at from what I recall.

That's a good point, and I honestly wasn't paying attention, but in my time with the AH3 I've never seen the battery drop below 80%. I don't think a dyno would change it, but who knows for sure. I'll keep an eye on that next time.

Do a 5 minute drive in Sport+ before you dyno. The battery keeps charging in Sport+!
Their will certainly be a difference on the dyno between a full and empty battery.

Always dyno on Sport+ (much better throttle responsiveness).
Does the BMS blocker work well? I just ordered it. It's so frustrating when pulling against a car and suddenly there is a kickdown.
When you pull your lever to the left, does it show S1/S2/S3? Or just DS?

And I believe 5th Gear is always recommended on the dyno. Right Darkiedm4?

I pretty much always drive in Sport+, and I know I was in Sport+ during the 15 minute drive there and during every run we made. This makes me think the battery wasn't drained, but I can't say for sure as I wasn't watching that.

Haven't actually used the blocker yet, I might sometime this week just to test it out. When I pull the lever over, it's S1/S2/S3... until I hit a paddle or move the stick up or down, then it's M1/M2/M3....

[afranke]

OK, here's the dyno graphs (let me know if I formatted them incorrectly or am missing some information):

With OTS Tune after driving around with it for awhile


Stock Tune


Back to OTS Tune

Dyno is in 5th gear manual (M5) for the 8AT and DSC OFF!!! Car will not kick-down in M5 - mine doesn't...

[Bestodabest]

Why would the alternator be constantly charging in Sport+? Isn't that the one mode you'd want max performance, which would equate to minimal parasitic draw on the engine?

Not exactly, it isn't the alternator here but the electric engine of the AH3 (in the gearbox) that plays this role and it's regenerating battery in all situations where you're braking/coasting, but conversely provides additional torque ("eBOOST") when accelerating.

Also in the manual:

eBOOST
Accelerating quickly, such as when passing, re‐
quires the maximum available power from the
electric motor. To do this, apply extra force to
the accelerator pedal.

The AH3 still kick-downs in Manual..don't ask me why. Programming error perhaps .

I's the battery of the Activehybrid 3 I'm talking about .

I'm glad it's not just me then. I swear the non-AH3 doesn't do that. In my experience, Manual mode is only very just slightly manual. It seems to hold the gear just a little bit longer before it decides you have no idea what you're doing and need a different gear.

Yes it seems like the AH3 has 8AT software instead of 8SAT. When i pull my lever to left it shows DS and M1/M2/.. like the normal 8AT. I heard an update solves this, but it looks like it only changes the gear display (S1/S2/..) but not the actual gearbox behavour. And yes this is extremely frustrating.

I got a software update last year, before it was DS now it's S1/S2/...

Yes but it still does a Kickdown in manual when you floor it right?
A real Sport-Automatic doesnt do that crap.

After a Dyno my 335iH full stock have 295WHP

With a tmcmotorsport (+5psi settings) same day same Dyno table car show 330WHP

Got graphs? Do you know what kind of dyno and what correction factor was being used?

[franzzz]

Try to put a printscreen soon......

4th gear, DSC OFF, "start roller on secret menu ON"

Full battery? And i think you should always ask for the runs per map.
