I'm looking a new car with 4 doors to replace my 135i.
I'd like a hybrid and am considering a 335i, AH3, or 330e.

Anyone with experience tuning this thing give me feedback?

Seems as though a nice tune plus the motor could get an AH3 up to 400ish hp, which with a weight at 3600 lbs, is close to the M3. And prices for these are great.

However, I question the whole idea because the emotor replaces the torque converter. Wouldn't messing with the power mess up the shifting process? How do you know if the computer program running the emotor in the transmission is performing its job correctly for the new power?

Has anyone been brave enough to track one of these? Could be amazing even stock with its power, yet I can feel my ZF6 heating up at the track, can the emotor in the transmission handle this type of stress? Surely BMW the AH3 with performance in mind offering an M sport version.

Next question: 330e seems safer to tune. The engine is detuned down to 180 so bumping it up to its normal 240 is easy plus the 80 HP from the emotor puts you at a respectable 300+. The downside is, its a rebranded AH3 but with a big fat pig battery in the back weighing in at 3800. Your power weight is down 11.5, IF the tune works with transmission. from the wonderful AH3's 10.9 or if the tuning works out a solid 9, which sits happily with an M3.

Of course the 335i is the obvious choice for light track duty, but, I'm simply going to be depressed going from a 135i N54 to a fatter 335i N55 with a slight drop in performance due to weight and prices are still $30k (more if you want a stick). Hard to feel good about dropping a bunch of cash and going slower with not even a MPG improvement.

So anyway, opinions on tuning, what you would do, and over reliability welcome. I'm strongly eying the 2013 as they sit at $16k. I guess people fear the battery replacement?
Hi!

I did a couple of track days with the AH3, it's fine if you upgrade the suspension to something stiffer in my view, or the weight tranfers will be hard to manage; that being said these cars, 335 or AH3 or 330e are no track beasts, and to be honest i didn't even like the m3 more, they're all heavy.

The front end camber out of factory is also an issue for track duty, and you need a solution to this, caber plates or other.

I like the AH3 on the road, it's fast and powerful enough, and when you can adjust camber it's agile enough too. The I6 engine is what i wanted vs the I4 of the 330e.

Tuning wise, i managed to get a stable tune from a local tuner but it wasn't powerful enough for a stage 2, they claimed fueling issues, i suspect something else like load limiter as my hpfp has never shown any weakness in my bm3 logs.

B48 engine i think is just starting to get tuned, not yet supported by bm3.

I don't think any of us experienced issues with the gearbox, these things are designed to handle more torque than a regular 335i if you look at the specs.

If you're into tracking perhaps aim for m135i/m235i they are lighter, slightly tuned (over 335i), come with increased negative camber from factory.
I wish on the 235i, but my wife demands 4 doors.

I guess general question about the F30: is the sport or (Msport suspension of you like the new marketing name) in the M package essentially the same as the sport suspension that came with my e82?

I've heard a lot of complaints about the F30 being far too Mercedes like and floaty compared to the previous generation. Is this for the base suspension or does it also apply to the sport as well.

Is yours equipped with the sport suspension.

Glad you like the AH3, and appreciate your response.

Also, for reference, I had the chance to ride along in a 911 carrera at Road America, it seems to me, as passenger the base Porsche suspension tune is equivalent of the sport suspension upgrade on my 135i. And my personal take is both are just barely suited to track use in stock form. Tough to manage weight but still able to keep up with slower M4 drivers.

Great on the street though.

I am attracted to the AH3 because it's low price leaves me plenty of money to make it track ready.

Of course, I'd like an M3 but I won't be dropping more than $30k on a toy with my mountain of loans from school still haunting me.

Thank you ! I've reset the learned adaptations (v4 map) and the rough start and oscillating idle is now gone.
The only issue left now is self-accelerating in low RPM. was this solved in any of your test versions Lancelot ?

Yes that's been resolved as well, so i'm sure halim can do that for the next OTS but best submit a ticket too for your car

I stand corrected - i had the issue this morning in traffic , car would accelerate at zero throttle. I'll check with Halim

I retract my statements as well. It was ok for a day after the reset, now rough start and idle revving is back. opening a ticket

Just to keep you posted, there's something at play I don't understand... One day it's fine, the next it's pulsating again.
I'm on a fourth test map which was just fine yesterday and the day before and today is unstable.

How many miles/km do you average a day?

Do you think it’s the ECU adjusting to the new map?

How goes the testing? Any progress thusfar? I got a test map from Halim a few days back, but I'm curious to know if you've done more.

Hi!

Not going so well, the map isn't stable, pulsating idle and hiccups while driving - problem is the same map was perfect the day i flashed it and the next, then it wasn't anymore and that randomness makes it hard to understand.

So i'm back to stock tune for now, but i'm not sure if they know what to do next.

How is it with you on PWG maps? Are you experiencing the same symptoms?
It was actually better on the V1 of the OTS map this summer after a few changes

What happened with your working with cookiesowns on the BM3 tune for AH3

Was gung-ho last Summer but hasn’t posted in this thread over the last 6 months and you haven’t mentioned him?
