Detailed answer: It's only at 1/2 to full throttle in 1st gear that the car can't hook up. In 2nd gear, the car hooks up no problem up to 3/4 throttle. Full throttle can make the tires spin if conditions are just right (or is that wrong? haha). The car does chirp its tires shifting quickly into 3rd gear. But once in the gear, there is no traction issue at all. We've done some pretty neat tricks with boost response that I'll disclose in detail soon. Quick story is that made our computer predictive of what kind of power delivery the driver wants. It will range from a progressive spool up to an "Slam Bam!" instant spool up depending on what it determines to be most appropriate for the situation. It's pretty damn neat. And it works too!!! When you're driving around normally, you don't have to worry about wheelspin (even with DTC off). But when you're driving hard, it's all you in control.

Now the M3 has to come up with at least 550 HP...

[Dannys M3]

Shiv,
Awesome progress, you rock :rocks:. The upgraded hardware for us beta testers is very nice gesture on your part and it shows people how customer orientated you are.
Have you put any thought into the 12 psi threshold and how we can better take advantage of some race gas?
If you get back to florida let me know so we can run over to Rachels again for dinner (work permitting).

Nah.. Realistically, we're still only in the 400-410bhp range with the 335i. The torque is another story of course (450lbft anyone?). But its at a low enough rpm range that it doesn't come into play during full-on acceleration (drag race for instance). But driven normally around town, of course, there is no doubt that the tuned 335i will likely outperform the new M3. In a drag race, however, it may be more of a challenge to keep up with a ~420bhp M3. But we're not done with tuning this thing yet so who knows what lies ahead.

Man... this is so exciting. Keep it up!

I won't be an early adopter just b/c my funds are so limited now, but rest assured if you guys keep on with this level of quality development... I will be a XEDE flogger for sure.

I love hearing about your work. (Wish I could be a tuner too, but I can't quit my day job )

Regards,
Michael

[Patric 335]

I cant wait til you come down to LA in Feb. Wish you could bring down a few extra exhausts. I want to buy one of those!!! ^_^

Damn you
I was going to wait for the M3, now I'll have to go for the "test drive" in the 335 this weekend

Thanks for the info!

[imsambeen]

Hey Shiv, So is this the suprise update you were taking about?
so for all the skeptics that told me not to have gotten the beta tester, now look I get a new xede. Ha ha ha

You rock, Keep up the awesome service and product

Hi Shiv are the new XEDE units being shipped now?

Wow that predictive feature sounds incredible. Thanks for the feedback and I'll see you in LA on the 10th

[bnj]

Predictive boost response - awesome!

[musc]

Yet even more impressive results

I am curious to see what a 93 octane Stage 0 (sans exhaust) will do with the updated Xede.

Thanks for the update, Shiv. Keep up the great work :rocks:

[specialque]

Can we have pictures of the exhaust you are using?

Shiv,

Are you still thinking with 100 octane you might see 30 more HP/torque than the 353/405??!!

With 450 lb/ft torque and 410 peak HP the broad HP curve of a 335i will already make it match a 420 HP M3 V8. Crazy!

BTW, for all you out there concerned about BMW loosing money on warrentee and wear issues due to the XEDE, just THINK about how many folks who never considered a 330i are now breaking out their checkbooks for the 335i due to the great potential of MODS, baby, MODS! 450 lb ft of torque is ALMOST what a Z06 7 liter V8 makes!

[edgarj]

This is sooo cool! I wasn't expecting any more gains or such elaborate tweaking, but Shiv is really blowing my mind with these latest revisions.

Straight 100oct would probably be worth another 30-50lbft of torque since it would allow me to run 15-16psi safely in the low end/midrange and more agressive timing/fuel curves. The turbos dont have the capacity to support much more boost up top so I'd be surpised if we saw much peak power gains. Perhaps 10-15whp-- most of which would come from the fuel/timing tweaks. We'll dig into intercoolers and induction plumbing/piping next to see if we stumble upon any airflow gross restrictions. Fingers crossed...

[sflgator]

This is all great news, Shiv!!!! Thanks for your continued hard work to make the Xede even better. It's really quite amazing what the Xede can do, even without your extra tweaking and refining...but this is all just incredible. We look forward to the new, much improved version of the Xede (and to an easier DIY install/un-install), and thanks again for allowing us 'early adopters' to get a free Xede upgrade! I guess we really were "beta testers."

shiv

fingers crossed? on one side i hope you find something so more power can get pulled out, but on the other side i hope its all effecient and nothing can be done because replacing that junk is expensive and time consuming/ possibly warranty voiding and i wont be able to stay away

[CASHBY]

just insane!!!

i want to see a 100 octane dyno!

[razormy]

For those of us that do not want the dealer to even glance at us, what are the figures without exhaust. What rwhp and rwtq gains on an exhaust added to the package.

Money order on it way tomorrow.

Thanks.

Ya thats true. But I would think esp with turbo cars as a "tuner" you would expect to replace / change these things sooner or later.

More later than sooner.

[IMJUSS2NASTY]

Is there any way that we can keep boost up on high rpms?
