Matt, you have 6MT or step?

Michael,

you hit 216 with your GRUPPE M? or was that without?

[///Matt]

You guys ready for a BIG part of my numbers?

As I said, I have a few tricks up my sleeve, and wondered if you guys remembered who I am...

Well, being a BMW technician at a dealership, with acccess to all of BMW's computer equipment and diagnostic tools, has it's perks.

Monday afternoon I cleared all my fuel trim adaptations. You know, the part of the car that "learns" how you drive, and adjusts for best economy while still providing good power?

Well I blew all that out.

Then I drove the car like a GODDAMN MADMAN the rest of the day. Kept my foot in the floor, whilst I drove about 25 miles. Then I parked it for the night.

Tuesday morning, I drove to Technik at an optimum time to avoid traffic, and I didn't let the engine fall below 4000 rpm unless I was stopping at a stop light. Kept the car racing between 4000 and redline, in several different gears.


By the time I got to Technik, my baby thought she was a ROCKET SHIP, and the DME (digital motor electronics) was fueling the car accordingly.


But that's not modifying the car. That's just proving what it can do.

This is different from removing the battery cable. Removing the negative battery cable for at least 16 minutes will accomplish a similar clearing of the adaptations, but in my experience it doens't stack up against an actual forced clearing... After it's cleared, convincing the car it belongs in F1 is the real HP unlocker.

Yes, it was with GruppeM, and remember, I often drive my car like grandpa who actually drove a Model T.

Matt, how did you "force" clear your fuel settings? You implied the battery disconnect doesn't clear this the same way, and the data storage is probably not via an EPROM.

That brings up a good question, is there anyway to program the computer to force aggressive fuel mapping regardless of how you drive? I would assume, if you take it easy from now on, the computer will "learn" the new driving pattern and detune itself?

NIce Info...My mechanic is a tech at bmw and does my work on the side...maybe i can get him to do this for me..

You are correct, it will slowly go back to regular driving characteristics. I plan to clear adaptations again today, so I get my MPG back! lol.

There is a way to force the aggressive fuel mapping at all times. It's available from Evotech, Tehcnik (not finished), and Dinan (not finished).

If this were the case, then it would be trick to have a switch for normal and sport modes.

So how do you force clear the digital fuel settings?

[Gooby]

so where is this Bastuck exhaust from??? Germany? cant wait to hear is as I am trying to decide whether to get Eisenmann, Ikon, or maybe even this.

[///Matt]

You'll want the Bastuck if even just for the bang-for-the-buck factor. It's an AMAZING price for the full catback. contact Ilia@Industry for pricing.

Michael, I cleared my adaptations using BMW's current diagnostic tool, the GT1. It's something you'd have to go to the dealer to do, unless you know someone with a GT1.

As far as switching back and forth between maps, there IS a product that does this. It's called Xede. Shiv@Vishnu is using it to GREAT success in tuning 335's. It's a piggyback ECU that "convinces" the DME to perform the way the Xede asks. It's got "on-the-fly" switchable preset maps, for economy/performance, or top-end/low-end, etc...

I'm in negotiations with Shiv to try and get this product into the hands on 330i owners, and SPECIFICALLY 330i owners. it'd be an entirely different development for the 325, sorry!

So Mike, if you're interested in this Xede, PM me, and we'll discuss it's fairly hefty price tag. It's kinda spendy right now since we'd be paying for the R/D to make the damn thing. I'll need sincere interest in the product from several 330 owners in order to make it an affordable reality.

Now here's my question...Assuming cost is not a factor in this Bastuck or Eisenmann full cat back?..Consider the quality, sound and performance also..thanks...

[///Matt]

Oh, I certainly will keep all these things in mind. I'm a picky consumer.

[PresaMat]

Matt great work! I have a quick question maybe you can answer me. Does the DME do the same thing with both step and manual? Or is it only on the step? If I drive my manual like a beast will it show higher performance too? Sorry for my ignorance. Thanks again for the great info you provide!

Hmmm..Maybe i didnt word my question correctly... I was trying to ask you which exhaust you thought was the better of the two cost not being a factor, only quality, sound and performance wise...

[Gooby]

full catback?? damn the eisenmann is like 900 just for the exhaust. So im waitin for this.. Hope you can post some clips!!

Yes, the DME will work exactly the same! =)

Shady, I understood. I don't have my Bastuck in hand yet. Hopefully this evening, but not yet.

I'll be posting pictures/sound clips, as well as a full review of the quality, performance, sound, and looks.

Thanks for the help Matt! Im coming from a 87 Saleen with a pretty nice V8 so getting over 13MPG is great in my book. Guess Ill just drive the 335i when it comes next week like a bat outta hell!

Mat

[ward]

am I the only one who keeps reading bat-suck instead of bas-tuck?

[///Matt]

Presa!!!

Do yourself a HUGE favor.

Call 1-310-306-4060. This is the number to Technik.

Ask for Mike, but if Mike is not around, Zolti is WAY MORE than adequate!

Ask his specific opinions of breaking in a 335. Since I've never owned a turbo, I'm not willing to try to tell you the "best" break in for your car. I know you shouldn't be baby-ing it, but perhaps there's a limit?

And Ward...

LOL. I certainly don't expect it to Bat-Suck! lol. I'm really exited to see what this exhaust is all about.

Oh my bads...I thought you had it on already..lemme know A.S.A.P cuz i'm ready to pull the trigger on the Eisenmann cat back but was holdin' out on it till ur review on the Bastuck exhaust...

[///Matt]

you should DEFINITELY wait.

The Eisenmann is a proven excellent product. It provides a TERRIFIC sound, great looks, and a performance gain. It's made of top-notch materials.

But it's price tag weighs more than the exhaust system does!

Wait to see whats up with this thing, before spending twice as much on the Eisenmann.
