Hey, thanks for the input. My 340 is my daily so I dont want my driving experience to become a nuisance. I do go WOT pretty much everyday in 2nd/3rd gear merging onto highways etc. I just don’t want to deal with acceleration interruption or the car cutting out on me mid pull

99% of the time, you only get the power drop at a gear change if you don't get off the throttle slightly. Bootmod3 is also a idea now, and it offers more for less money (of course I did some reading, now I have the itch). You do add the risk warranty issues with a tune vs piggyback though.

You need to fully warmup and then ease into the power at 3/4 throttle if you have an AT. Interesting is the MP transmission tune. I wonder how that would pair with Active 8? At the end of it all, an ECU and TCU flash is the best way longer term. I am still hanging with A8 for now.

I have little knowledge of auto mechanics. Would A8 be less beneficial with no exhaust and air intake upgrades?

Alarmin · 04-09-2019, 04:08 PM

As an update, I recently installed the Bootmod3 Stage 1 91 tune. What I've noticed so far:

- Shifting at WOT is basically stock feeling - no more harsh shifts
- Active 8 seemed to push me back into my seat way harder, could be all the extra torque down low. I think there may be some more power to be realized with my tune so I'll be sending PTF some logs to see if there is room for improvement. Will update afterwards. If the BM3 tune in its current state is meeting its full potential, I will probably be switching back to A8.

On the heartbreaker mustang dyno, A8 is pulling close to 420 ftlb/380HP on 93 octane. Intakes and exhausts do not get you much power.

here is an Active8 dyno on a 340i /w standard numbers...

Mods; 93 Octane, Active 8 Tune, ER Catless Downpipes, BMS Intake, Muffler Delete

How many lbs of boost do you have the controller set to?

Does it feel to you like you are driving over small rumble strips or like ABS-style cycling when you hit the fuel limit at WOT? By the way which setting do you use?

Wires · 04-09-2019, 09:07 PM

It was more of a stutter feeling when it happened (but it did only occur a handful of times in 2 years). I was using the default setting.

hokiedood · 04-09-2019, 09:18 PM

I assumed with the A8 the car would need more air intake and would produce more exhaust. Just thinking those would be a bottleneck.

This is from another member named BREAKER1097 on here so I don’t know. But I’m sure he could tell you.

BP340 · 04-18-2019, 09:22 PM

I installed yesterday. I always get the "stutter" shifts at WOT. I will leave the tune on for a couple of weeks to see what happens. The car definitely is producing power, but I am hitting 7K and it seems to pull power as it is shifting. It is almost like bumping the rev-limiter that I have experience in other cars. Hopefully it works itself out, and is not causing any damage.

Savageenterprise · 04-24-2019, 12:43 PM

Has anyone experienced a power loss when going from WOT from gear to gear and rectified it by reducing the gap in spark plugs to overcome the boost increase?

The power loss when shifting isn't caused by a spark plug gap issue, it's because of the transmissions torque intervention stepping in. It seems that the piggybacks have more issues with this than flash tunes.

I have a manual so I'm letting off the throttle at shift point. It's not that

What gap are you set at?

Factory plugs and however they come gapped. I haven’t taken them out to check or re-gap so idk

Hi Alarmin

Can you clarify something please?

I see you mentioned the M Package and the dyno shows 328 HP before the AA

Do you have the M Package that includes the added HP? I do and my HP is approx. 355-60 - curious why your number is lower.

Thanks

M-sport does not give you 360HP. MPPSK upgrades the car to 360HP.
