bsr causes psi breakdown after 4800 u/min

[german gt]

hi bsr fans.

Anyone recognized (yes i know your speed limit ) a significant lost of turbo pressure with bsr installed on a stock rl in the 5th gear under full power after 4800 rpm.

Same effect dynoing the car in the 4th gear.

After 4800 rpm pressure lost from 22/23psi linear down to 16psi.

Cold temperatures, no problems with original software.

Only 260 Hp at 4800 rpm becuase of pressure break in.
Original 264 Hp (200 whp) on the same dyno/day.

The bsr is designed that way, it's normal. Power falls off in 4th-5th to protect the motor on long pulls after 4800rpm (turbo heat)

first: it was no long pull. it has been a pull starting at the fourth gear and it tooks only a minute.

second: you did not read all of my post?

it happened on the highway too!

yes we can drive as fast as we can.

so it is definitly NOT NORMAL

the bsr tuned car has less power than the orignal engine.

NOT the bsr protected the car, its the ECU which does not like anything in the bsr tune

BUT WHAT?!

if the BSR flashes the PCM, which if its tuning software, it probly does, then the parameters are set by the tune NOT the PCM. If it doesnt normally do that in the stock PCM, then it was set by BSR. If it wasnt set by BSR, then there may be something physically wrong with the car not just the PCM.

Or maybe you got a screwey tune. I would contact BSR for further help, or you can try and tune it yourself.

MAKE SURE U SAVE THE ORIGINAL PCM TUNE SO U CAN REFLASH IT IF SOMETHING GOES WRONG! Dont want gm scanning it and saying "something looks fishy".

non warranteed engine work = rapage

Listen to what I have read, regardless of what gear you start in, power is limited to stock levels past 4800rpm in fourth gear and fifth gear. This is done to protect the turbo and engine.

What you read, must be wrong.

Because you cannot sell 312 hp and 450 NM ,
wenn you limit the power at 264 hp

There's an easy way to protect the engine: fingers of bsr!

the car is fine...

and the bsr tune only overwrites a couple of datasets in the ecu, like fuel, ignition, turbo pressure, kocking sensor etc.

the rest is still controlled by the car (exhaust temperatures etc.)

so anything is wrong with the bsr tune - they are still working on the problem.

Have you checked your hose clamps? Maybe it would be wise to invest in some t-bolt clamps, its a pity gm didnt use those beefy ones in every section.

[german gt]

I'll checked the hose clamps a couple of days before and had to tighten one !!

So the hose clamps are still okay.

[forkee]

are you saying you have a malfunctioning bsr tuner?

or is this a problem in ALL the bsr retune kits?

im gonna be forking out the money next month and need to know if there is any problems with their reflash kits. cuz thats alot of money....lol

[shabby]

There must be an explanation for this, if you had a dashhawk you could see what the ecu see's. Is it knocking? Is it pulling timing? Is the afr out of whack? You name it.

Go re-read the BSR website, it's plain as day.

Ignorance doesn't make the truth go away, I promise

so please quote the text on bsr website you mean.

otherwise your posts won't help to find a solution - sorry

of course there must be an explanation for the effect.

no knocking (european 100 oktan fuel used in race series like dtm)cold
temperatures (12° Celcius outside, 15° Celcius engineside, shown bei the OBD)

pulling on one of the best dynos available (up zo 1000 hp, 4x4 etc.)

May be to much load und full power (5th gear on the Highway, more than 4800 rounds and 130mph...)?

WHO OF YOU US BOYS ever drove the car over 140 mph?

With or without a bsr tune.

We can do this every day!!

So maybe more bsr tunes are effected and you cannot feel it because of your speed limits?

Reference that post (and the rest of the thread) by BSR's primary vendor in the USA.

well, I took my cobalt well beyond 140 mph on back roads with wet bumpy pavement (not straight road either ). Does that count as going beyond 140 mph?? BTW, mines limited to 160 mph, which I think redlines are limited to aswell.

Yep... and in the morning you wake up over there! We don't! It's worth the speed limits

sorry.. I know childish response to a childish comment... still true

[MidniteBlues]

I thought I was told that the autoban speed limits have been changed by the German Bundestag years ago and set at 110MPH?? Which converted, equals approximately 177.1km/hr speed limit.? I read and was told that there IS a limit now in Germany--Ahh, a little research shows that there IS NO speed limit "unless shown" I like that arg arg arg-- So looks like there is NO speed limit on the autobans--oh yea and no tolls--

Germany

German autobahns are famous for having no universal motorway speed limit, although about 30 % of them have posted speed limits[4] and about 10 % are equipped with motorway control systems that can show variable speed limits.[5] There is no national speed limit, either, for cars on marked "Schnellstraßen" (Express-roads) with a central reservation or a minimum of two marked lanes per direction. On such roads, as well as motorways, a recommended speed limit (Richtgeschwindigkeit) of 130 km/h (80 mph) applies. While driving at higher speeds is not punishable, the increased risk induced by higher speeds (erhöhte Betriebsgefahr) may result in partial liability for damages. Moreover, the law forbids to travel at speeds that would prolong the vehicle's minimum halting distance beyond the driver's line of sight.[6] On all German roads, there are speed limits for trucks, buses, cars towing trailers, and small motorised vehicles (Mopeds, etc.).

The introduction of a national speed limit for motorways and similar roads has been on the agenda of various political and environmentalist groups for decades, but at present, there are still no definite plans on behalf of the federal government regarding the matter. The Umweltbundesamt (Federal Environmental Agency) repeated its recommendation of such regulation in early 2007, but the current Merkel administration sees no need for it. Legally, however, state and even local authorities have the power to enact speed limits. A statewide binding speed limit of 130 km/h, for example, was established in Rhineland-Palatinate over a decade ago, whereas the district of Cologne has posted a speed limit on the heavily frequented Cologne Beltway.

On rural roads that are neither motorways nor roads as described above, there is a national speed limit of 100 km/h (60 mph). Lower speed limits apply to lorries, some buses, and cars towing trailers.

There is a general speed limit within city limits of 50 km/h (30 mph) but residential areas usually have a lower posted speed limit of 30 km/h (20 mph). On arterial roads, the speed limit may be raised to 60 or 70 km/h (37 to 43 mph). Motorways crossing citys count as normal Autobahns and can be used for travel within larger citys in many cases.

Ich bin froh, dass mindestens Sie noch keine Geschwindigkeitsbegrenzungen auf vielen der autobahns haben, es genießen, während Sie können.

Ich bezweifele, daß es jederzeit bald geändert wird. Selbst wenn... es noch sehr hoch ist. Können Sie 100mph sagen?

Anyway... to the origonal poster...

German GT,

It does not matter how fast you can go.

Bragging that you can risk death every day does not change the information that has been given to you.

BSR sets that limit on purpose.

BSR made it like that to protect the engine.

Long run, short run, neither matters.

The tune only modifies settings for the low RPM range. If it kept the modified settings all the way up, you could blow your engine.

You would be even more vulnerable to an exploding engine since you can drive at 140mph all day (compared to us lowly state-side drivers that can only see those speeds in bursts, or on a track).

The autobahn was fun. It might have been more fun if I hadn't been in the Fiat equivalent of a Ford Escort that did not want to go over 85mph even downhill!

I figured out that someone in the left lane with their left blinker on in Germany is NOT so
