Go buy laptop real quick. Use hotspot with LTE. Then go back and return the laptop that day. Or use amazon cuz returns are easy. Get cheap laptop.

I just did the standard tune for the 3sim. I think it would be nice to have the options ike the JB4 tune. If you wanted to have some burbles, you could select that tune temporarily. Then when you want to get back to the real world you can switch back

I already did the tune using an old lap top. You only need internet to email them your tune and get your tune emailed back. Other than that there is not need for wifi so I was all good.

Hows the tune running? Any differences? Also what engine do u have and mod?

How many miles was on your car when you got your tune and how long has it been since?

[S65Hunter]

Go back a few posts, i explained how the tune feels. As for mods, all I have is 3SIM, Revmotoring silicone intake tube and magnaflow muffler (#12148). Some point this week I will be doing secondary cat delete. My only issue right now is a SES light that I can't get to go away...

[S65Hunter]

Well I've found 1 thing I don't like about the tune that I found out on my way to work this morning. Im still limited to 135mph, whereas the other tunes offered get rid of the electronic limiter.

Here are combos of tunes BPC offered before (I believe Bob still offers):
stock manifold
3IM
N54 manifold
stock manifold + headers
3IM +headers
N54 manifold + headers
stock manifold + MILVS
3IM + MILVS
N54 manifold + MILVS
stock manifold + headers + MILVS
3IM +headers + MILVS <- I am currently running this one without headers installed
N54 manifold + headers +MLVS
Burble tune for all above variations

W37V Thanks for your input, I'm also trying to decide where to go for tuning. So far just have charcoal delete,silicone intake tube, secondary cat delete, muffler delete. Contemplating MILVs, but prob not headers. Commuting 75%, canyons 25%. Should I just go AA tune? Or can I make a custom tune by modifying the DME file myself via bimmerlabs? What software does one use to modify the fuel/valve maps?

Also, do MILVs decrease fuel economy? Or just make you want to drive harder, therefore killing your mpg lol...

TIA!

AA can't do anything with MILVS. No, they don't decrease fuel economy (your right foot might).

Nice. So MILVs and a tune is roughly $325 + $650 = $975...

vs

$459 for AA tune sans MILVs. Actually add $225 for their proprietary cable that you can't use for anything else...

So what are we talking about here as far as performance #s between the two? I think I saw +15HP for MILVs and tune over stock, but how much over AA tune? 7HP?

I'm not tracking, so I'll prob go the cheaper route and put the rest of the money towards the B14 Bilsteins I've been waiting for...

Also, what are the implications of running a catless (headers) tune with stock cats? I assume it's just gonna dump more fuel because it expects more air with less backpressure? So you will end up running rich? Or will the closed loop O2 sensors measure that and trim it out anyway?

[hassmaschine]

I wouldn't recommend AA to anyone, personally.

A catless headers tune mostly just disables the downstream O2 sensor errors. Bob may also adjust the parameters for the feedback loop (I know I would). Backpressure has nothing to do with it - fuel isn't touched because you have headers, that is all target based and isn't affected by having headers or not.

But I don't know why you would run a catless tune if you have stock exhaust manifolds anyway. Just get a regular tune?

I can't speak for bimmerlabs tune. I would love to try it, so I can truly compare most popular tunes being pushed on the forums.

Regarding other paid tunes (AA and Stage)
As someone who actually run AA and BPC (Stage FP) tunes, they are very comparable. The latest AA tune matches BPC low end torque. On top end, bpc and aa were almost the same.
If you will not do milvs, AA would be perfectly sufficient. You might actually get better fuel economy as you will be pressing your accelerator less, thus saving more fuel.

Thanks for the useful info...

One more thing, if you do a google search for e90 tuning file, you get sites like ziptuning.com and mychiptuningfiles.com and dyno-chiptuningfiles.com. What is the deal with these sites? Are they legit? It's strange though, the pricing is for credits and they all seem to be in Euros....

[hassmaschine]

Those are generic tuning sites. I have studied them all (they are basically competition). They offer files for basically any car ever made - so who knows what you will get? Probably, not much. It's not like people are falling over themselves to develop custom tunes for the N52. And in the aftermarket tuning world, piracy is rampant.

Yap. What he said. Some people are doing a very good job of opening people’s wallets for very little ROI.

Yes they do. They sent me the file recently. I have yet to install my milvs though.

[hassmaschine]

Hope you don't end up in limp mode, and they did more than increase ignition timing by 3 degrees across the board.

I guess I'm in the minority. But I've had great luck with AA tunes. Base 3SI, + header tune at 242 Dyno hp. The car is now more powerful than my previous e36 m3's. And it shows. So no fear for me installing the next tune for milvs

Same here bud. U not the only.
I guess our dynos are fake and we go limp mode all the time lol

There are countless threads on the aa tune limp mode somewhere ...

I only recall reading 1 or 2 complaints on their latest TEST tune.. i did see numerous dyno sheets but i guess they all fake too

[franksinatra]

I also had both the AA and StageFP tune. When I had just my 3SIM, my AA tune would always throw a torque limiting error even after trying a few variations of the tune. Finally, the shop I was dealing with agreed to refund me the whole amount since they couldn't get it right. Since then I've gotten the StageFP tune and since day 1 it has run well. I've since added MILVs and then headers and Bob has tuned it perfectly every time. I know some people have had success with AA tune but speaking just from my own experience, I can't say enough good things to say about the tunes Bob at StageFP has provided me.

I never said it was fake.

But let's be real here. I have seen what was in the OTS AA tune, and you have not. They sold you a black box and you're happy with it. Fine, whatever - I don't like being blind and ignorant, personally.

so if my dyno says 230 whp and my baseline was 195 , that means they sold me a black box and i m blind and ignorant

I guess I may be delusional too since I ve never got a limp mode due to my tune ...

I m also guessing the other member that did a back to back dyno comparison between BPC and AA proving that they pretty much make the same HP must be delusional... I even said BPC was better overall

Or the other numerous DYNO sheets ( with before and after) from other members with AA tunes must be fake ...

If limp mode was a thing , I m sure they would be numerous threads on it... I ve been here for a long time and I havent seen them. I only recall some guys complaining about a test tune from AA , they were the first ones getting them and I dont even think AA offers that tune anymore

anyways , there is really not point arguing about this. You have your point and I have mine. I can show you dyno sheets but it wont matter. to you , so whats the point , it is what it is , we ll just have to disagree and move on
