Btw, in sports it is also significantly lower burbles than S+ so you may need to wait for custom tune or self tuning to get what you want

Appreciate that info... I take it you are running the a tune of some kind, bm3 as well? What are your thoughts?

No some of the videos are with stock exhausts - I made sure to check before...

Night and day over JB4, like a new car.

Hi Guys,

I'm running the BM3 in my car! This may have already been raised, however i would just like to confirm.

I'm about to go back for my 30,000km service, Should i load the standard file back into my ECU or leave the flashed BM3 map in it?

Also, If they flash new software into my car, do i loose the flash tune and have to start again?

I don't see a reason not to flash back to stock as it takes just a few minutes. (That is my personal stance, I prefer to draw less attention from the dealer)

Slightly off topic: I assume the dealer does not remove the ECU to update. In this case how come we need to remove to unlock but the dealer just flashes via obd?

Btw: when I asked the dealer to update all software on my car prior to doing bm3, I had my ASD module unplugged. This prevented him from doing the update at first. They actually had to troubleshoot and figure out it was the unplugged ASD that was blocking the update. I guess this can be one way of safeguarding the car from dealer updates (but maybe only on Harman Kardon cars)

I thought running the stock map would show a tamper code?

You need a modified file that has tamper code off.
PTF sent me one with tamper off for both stock and jb4 bef.

Stock "performance" map vs restoring your OEM flash. A full restore lights up the tamper code.

If they are really looking for mod traces they will find anyway.
My line of thinking is at least not to have burbles and a jerky throttle on a non ZCP car.

+1
PTF has saved a lot of folks the past 6 months with the Tamper Code delete

Not all cars trigger this; it also depends on the tool they're using to read/bench flash you the first time.

So is the E30 map readily available now? Are all OTS maps still free?

I ask because I'm having my ECU pulled here in about an hour and my car has over 3/4 of a tank of E35 in it... Even if I wanted to try I couldn't run it out in time. Am I going to be screwed?

EDIT: I see its 1 OTS map.

Anyone have suggestions on how to handle this when I was only planning on buying the 93 map?

At the time when i received my E30 stage 2 map, it wasn't an OTS map anymore. Its now a custom map (additional 300). Not sure if anything changed since but E30 map is available.

E30 OTS is available. My friend just got it the other day. I'm sure you can drive on their 93 OTS map to run through that tank of E35. Maybe you could even run with it at WOT without issues.

On their website you can select stage 2 and e30 now actually. S55 STG 2 OTS E30 is $100.

Well fellas (and ladies), I'm officially in the BM3 crew. My DME is in the mail as we speak. Heh. 😎

You definitely seem like their target demo.Please tell us you have already dynoed your car stock and with the JB4.

I'm sure a lot of people are curious to see how JB4 on a ZCP compares to BM3's OTS tune, and more interestingly, how it will compare once you start using the custom tuning feature.

I haven't yet dynod using my JB4 on the stock ZCP tune, but I'd guess I'm in the 500-520whp range or so on E42 @ 20-22#. I will probably keep the JB4 installed for a little while and dial everything to zero and just use it as a boost controller, which means I can still load my stock ZCP map and set the JB4 like I have it now and basically have the exact same setup I'm currently running for dyno purposes. Then, move the JB4 to pass through mode and load any of the BM3 maps I want.

With that said, I'm going to be doing some E85 testing soon, so I'm excited about how far I'll be able to take ethanol content on the stock fuel system as well as being able to tune for said ethanol. If I can manage E42 using the JB4, I'm hoping I can make it to E60 on flash alone. E60 would be awesome and would give me most of the detonation threshold benefits of a full tank of E85, especially when mixed with a quality 93 octane. We shall see soon enough.

I won't focus too much on 93 octane alone, as I'm not planning on running 93 pump in this car as I have access to very high-quality E85 (tests closer to E90) and will focus mainly on tuning for E85 mixes.

Either way, I'm excited to get up and running and finally have complete control over my DME. For an ex-tuner, I've resisted long enough.

You'll love it, completely changes the personality of the car in Sport and sport+. When I switched back to the stock tune after having run the BM3 OTS for a while I literally though my car was broken, it felt so slow. haha. You guys with access to e85 make me jealous.

Are they going to actually give you complete control of the ECU like you're one of their tuning partners or are they going to give you the same limited number of tables that they promised to end level users?

I'm really just curious to see if the control of the ECU they give to customers is enough to make power beyond the off the shelf maps on pump fuel. I know why people want to run ethanol, but the problem is that the quality level of E85 at the pump changes way to often, and not many people know how to mix consistently or keep track properly after each fill up. The only right way to run ethanol in my opinion is with alcohol monitoring. I'll gladly pay more for a good 100 or 104 Octane and just run a +Plus file when I go tot the track.

I can't speak for PTF, but I can assure you the basic tables the normal end-user will have access to will allow the end-user/tuner to tailor their tune for any number of setups and fuels. Boost Pressure Targets, Ignition Timing, AFR Targets, Fuel Scalars, Cam Angles, Fuel Pressure Targets and Overrun Tables would be some of the main tables the end user will need quick/easy access to while tuning. Of those, only Boost Pressure Targets, AFR targets, Ignition Timing and cam angles will have an effect on power. The rest are secondary controls/tables needed to keep everything running properly and/or drivability related. All of these tables have other associated tables that go with them, so it isn't a simple thing to condense, I'm sure.

There are a lot of tables defined, so I'll let PTF answer that question in detail.

As for the comparison of ethanol mixes (or any alcohol fuel) to 100 octane or even 104? I wouldn't be so quick to consider them equal. They are different and I'd take a full tank of quality E85 over either of those fuels any day. Hell, even E40 has certain advantages over some lower octane race fuels (I.e. 100 octane pump), especially when mixed with a quality 93 octane. A proper E42 mix in my car w/ 93 octane is 98 total octane (R+M/2). But alcohol fuels hit above their octane rating and have good charge cooling effects. This raises the detonation threshold even more, so octane alone doesn't tell the compete story.
