With regard to break-in, many customers tune the car with <50 miles, and some wait for after break-in. Our suggestion would be to wait until you have 1,200 miles and the run-in service completed. Let us know if we can answer anything else!

Hi, a few questions from a potential customer:
1. What is the HP / boost difference between stage 2 and stage 2 plus? What is needed to run 2+ except DP?
2. How is RevMatch in sport plus implemented? Same way as stock implementation in Sport?
3. I’m currently running BMS Stage 1 with injen intake. I also have catless DP purchased but not installed yet. What gains should I expect by going with BPM stage 2 vs my current setup? And last question, in case of installing catless DP how is the check engine light suppressed? Will it come back when reflashing to stock for service visits?

Thank you for your time. 🙏🏻

Also curious about rev matching in Sport+. Does it operate similar to the factory rev match?

Rev matching in sport+ works perfectly. It feels OEM in operation. Actually better because BPM’s throttle sensitivity is smoother than stock sport+. When combined w/ rev matching, it truly makes sport+ useable for daily driving (I always felt OEM sport+ throttle to be far too twitchy and sensitive).

Thanks for chiming in. That's' all great news. Planning a few upgrades in the news couple weeks and the BPM Port Flash is on my radar because of the rev match in Sport+ feature.

Just wanted to reiterate that Rev-Matching in Sport + does essentially use stock implementation, and feels amazing! Like AlterZgo said, it pairs very nicely with the smooth throttle sensitivity of our tune and really does allow for using Sport + to be used for daily driving.

Also wanted to linkAlterZgo's review/experiences with the tune which can be found here

What parameters/features are customers differentiating between Sport and Sport+ with rev matching? Open exhaust valves, extra burbles?

We currently can't modify burble/valve profiles in the different drive modes but that will change when we release switchable maps.

Hi Sam, could someone from BPM please answer my question 1 and 3 from the previous message in this thread? Thank you

Hi!
Ok the easy bits first, with our Stage II tune you'd see a ~70-80 HP & 115-125 ft. lbs over stock. CEL will be suppressed with the tune loaded and in the event you flash back to stock, the CEL would not illuminate for quite some time. Also, the function for checking catalyst efficiency is turned off. To run Stage II+, you would only need DP's. Finally, in regard to Stage II vs II+, Stage II+ is slightly more aggressive in the mid-range. Even with Stage II+ we don't alter the factory knock thresholds, we do recommend 93 octane minimum. For those that run higher octane, racing tunes are available.

When do u expect that you guys relase switchable map?

Thank you! So in terms of HP there is no difference between stage 2 and 2+? Do you have a dyno showing the difference in power curve between those stages?

Hi again!
Well yes stage II+ will produce more HP. Here is a Stage II+ Dyno from earlier in this thread.

I thought it was possible to specify "exhaust valves open all the time in sport and sport plus? Wouldn't this require modifying the valve profile for each drive mode?

Mike has set up my valves to always be open in sport and sport+. Also, my last flash had different burbles between sport and sport+. It was extremely loud spaced out pops in sport+ but I preferred the sport setting burbles frequency. In my latest flash I chose the ZCP (or maybe it was GTS) style and it's perfect. Sport+ is like sport but longer and a little louder. The throttle settings affected by switching from sport to sport+ is likely what inadvertently makes the burbles different between modes.

My recommendation is to go with the ZCP burbles and valves always open in sport and sport+ (OEM in efficient).

So they can tune valve position based on mode ?

[drgmt]

Can the car be made to start with all settings in efficient ? So drive mode, steering suspension all in comfort mode on startup ?

My car currently has valves always open in sport and sport+ and OEM in efficient.

I can use my valve controller to open the valves in efficient but it has no effect on sport and sport+ because they are already open.

I wish our car had a valve button inside - such a useful feature

Is there any way to flash the tuner map whilst leaving all the tables that control burble completely untouched/not overwritten - this would be a custom map I assume

With so much variation to the burble, from losing it completely to way ott, Id prefer to just leave those tables stock zcp

Has anybody had any experience servicing their M3/M4 after doing the OBD flash from BPM? Particularly if you did one of the stock flashes (eg ZCP).

Did the dealership notice? or is everyone flashing back to stock before they go for service?

I went in for a scheduled regular oil change without flashing back to stock. I have a 2016 m4 flashed to CS map.

I know everyone tells you to flash it back to stock. But I didn't have any issues and no one spoke to me about the tune. But who knows, maybe they flagged me secretly in their computer system.

I also made a note telling them not to update the software/firmware as to wipe out the coding that I had done.
