cp-e has reconfigured the Standback to use the CAN data from the DME in the tune. This was not possible before as the processor that the standback uses was completely maxed out and had no more capability. The chip manufacturer however, recently updated that item and now it has more capability with the same coding allowing Lou, cp-e's genius EE, to add CAN functionality to the Standback. We hooked up the BT tool to my car and he "listened" in on the transfer of the target boost data. He then emulated that process on the standback such that the it can now open a CAN session and request the realtime target boost of the n54 DME. He then spits this information back to the DME while independently controlling the wastegates. THe result is a completely open throttle, a completely happy DME, and COMPLETE boost control.

Before this the standback took over boost from the DME at boost greater than 5 psi. At values lower than that the Standback gave the car what it ...

The introductory pricing is very good, but the MSRP is not as good as expected. Rob Beck is taking $1500 deposits to get in on this ASAP.

RB mentions that the tuning is still a work in progress but that the JB3 seems to be handling the turbos just fine. I think any tune will be able to run these, should not be an issue.

You need to supply your core: Full ...

I'm not saying they did, just providing the information for you guys to decide for yourselves. This thread was censored where it originated so it became necessary for the discussion to be hosted here where everyone can get the uncensored details, as usual.

Here is what happened:

Guy goes to Mfest.
Guy has Powerchip tune.
Guy decides to try out ESS tune.
Says he doesn't want it, wants to go back to powerchip.
Claims ESS got upset and put a file in his car that damaged it as "revenge" or "payback" for not making the switch.

I must say, the E39 M5 is surprisingly strong. In 2nd gear it runs away. At higher speeds, the M3 does better with its stronger top end. My feeling is that if the M3 was DCT the 2nd gear run would have a different outcome as the DCT is geared much shorter 2nd to 3rd.

...

This is what Eloy from Raceprecision, who is an ESS dealer, is stating:

If this is correct, ESS will have the best value and has undercut the rest of the market, as in Gintani, significantly. ...

Stroker has:

Decated headers, secondary race cats, X-pipe, Eisenmann race mufflers, RPI air scoops and BMC filters. Stock ECU remap, will reflash with RDsport mapping once completion of break-in.

Bolt on M6 has:

RPI air scoops, BMC filters, and RPI exhaust

...

I don't want to say anything negative here, but, I mean, what can you say about these numbers?

91 octane, stock headers.

A huge congratulations to BMW Motorsport for pulling off a stunning victory. The M3 GT2's ran strong however one was set back due to an accident and the other was trailing the GT3 RS through the early portion of the race.

It has been 5 years since the last victory for BMW at the ring. Four drivers switched off in the winning car and made their way to the front despite gearbox problems in the critical last few hours of the race.

The second M3 fought back to seventh place after a crash that had them lose an hour and drop back to 182nd place. Talk about an impressive fight back to the front!

A duo of privately entered Z4 GT3 race cars managed to finish 4th and 9th as well. Of 198 cars entering the race, 63 were BMW's.

The Motorsport M3's continue their impressive racing this year from ALMS to the Ring, congratulation to BMW Motorsport for this hard fought victory!

After speaking with ESS over the past few days it was suggested that a friendly dyno comparison should take place with ESS coming out to California to participate on a third party dynojet.

BimmerBoost will be organizing the event that tentatively is scheduled for mid-June. The date may change to be able to accommodate everyone.

This will simply be a friendly dyno comparison of all the available options for the E9X M3 as well as the N54. The royal rumble of tuning so to speak So, who is going to participate?

Confirmed:

ESS
G-Power
Gintani
BMS
CP-E

Potentially:

Powerchip (contacted and has responded, depends on the dates)
VF E92 SC (contacted, responded, still tuning, not going to pressure them, our deadline is not their deadline)
OE Tuning

Waiting for response:

GIAC
Active Autowerke
Vishnu

I have made sure to extend the invitation to everyone. Note, this is not a competition but simply a comparison at the same time and same place by a third party for the benefit of all the consumers. ...

So, this image is circulating the web, is it really that big of a deal? People seem to be equating a quad exhaust with an M car. M cars have not always had quad exhausts, E36 anyone? E34? E30? E28? Frankly, for an N55 I6 a large piped single would be preferred and more efficient. If this is a true dual exhaust based on a split manifold, it would mean the car is running an N54 and two turbos. Otherwise, the exhaust is just for looks.



Here is the N54 twin turbo manifold to get an idea:



If it is an N55 a dual exhaust would not make any sense for performance. Clearly, a hopped up 1 series is coming, with either of these motors. Just tell what it is called already, and let's get on with our lives.

I have been telling people for some time that the DCT M3 M3 vs. the C63 is a drivers race, hopefully it finally sinks in:

...

We have learned that BMW is potentially considering an M7. Why? The recent sightings of the Audi S8 testing and the rumor of it getting an uprated version of the RS6's V10 Twin Turbo with over 600 hp have BMW considering the idea.

BMW already has a V12 Twin Turbo in the 760 which puts out 535 hp and 560 lb-ft of torque using very small turbos. If this motor was mated with the X5/X6 M turbochargers it would result in a devastatingly powerful vehicle which would be more than an answer to the S8 and finally give BMW a direct rival to the S-Class AMG's. Due to the torque, the automatic transmission from the X5 and X6 M would be used. What else is interesting? The M7 would potentially be available in AWD.

Potential Specs:

Engine: Turbo V12 with M Twin Scroll Turbo Technology
Power: 650-700 hp @ 5200 rpm
Torque: 680-700 lb-ft @ 1800 rpm
Transmission: M Six Speed Sport Automatic Transmisison

Will it happen? Probably not, such a vehicle would be extremely expensive although this has never stopped Mercedes or Audi. If Audi continues to put pressure on BMW especially by testing the S8 and RS7 with uprated ...

Now, we have had several discussions about ESS and I feel I was too aggressive in retrospect. However, today, I was reminded why I was so aggressive in pointing out what ESS does regarding misleading people with dyno graphs.

There was a discussion on e46fanatics regarding a blown motor by VF and ESS got dragged in. Roman@ESS then made this post:

http://forum.e46fanatics.com/showpos...7&postcount=89

Now, what is funny about this S54 setup? It is the exact same graph ESS used for an E92 M3 setup:

http://forum.e46fanatics.com/showpos...0&postcount=33

I am shocked, freaking shocked, they would actually not remember they posted the same graph for two different setups on two different cars and not realize that they would get caught. Now, you might be asking yourself, does ESS really mislead people this way with graphs?

Well, I honestly wanted ...

This deserves a congratulations.

1. Stock w/ Powerchip 91 v.2 & CAI; 338 RWHP unknown torque
2. Supersprint Headers & CATS; w/ Powerchip 91 v.2 & CAI; 358 RWHP & 328 lb. ft torque
3. ESS S/C w/Supersprint Headers & CATS, 96mm pulley & 93 oct software @ 4.59 psi boost & 50/50 race gas; 479 RWHP & 396 torque
4. ESS S/C w/Supersprint Headers & CATS, 92mm pulley & 93 Oct software @ 6.27 psi boost & 50/50 race gas; 509 RWHP & 420 torque

So with headers, race gas, and more boost it crossed over the 500 whp which is very impressive.


Here is the graph:

I will share some more information with you:

1) engine management- CP-E standback and profuel controller will be utilized.
2) Fuel System - Custom duel walbro fuel pumps with six additional injectors. The six injectors will be approximetely 180-210 cc and be positioned in a spacer between the engine and the intake manifold. Fabricating a new intake manifold was not worth the cost.
3) Exhaust Manifold - Equal Length Manifold
4) Turbo - GT37 Twin Scroll
5) Wastegates - Two Tial 38 mm Wastegates on each end of the exhaust manifold
6) Blow Off Valves - Two Blow Off Valves. One recirculates air, one blows off
7) Downpipe - 3 inch downpipe
8) Exhaust - 3 inch exhaust
9) Intercooler Piping - 3 inch too
