... without my car beeping at me!
Not that i travel at 100mph often, but still, it's not right?

My cars a W reg MY00 classic and is RR'd at 269bhp @ 1.2bar.

Ive had the car a couple of months but its only just started doing it.
When im in 5th gear with my foot to the floor (doing approx 100mph) my turbo timer reads 1.24 (bar?), beeps and flashes red at me, and continues to do so until i slow down.
Even when im doing 80mph in 5th accelerating my turbo timer reads 1.20/1.21 (bar?), beeps and flashes red.

Im hesitant to keep accelerating when clearly my car isn't happy about it (beeps, red flashes), so at the mo a Corsa could top out after me.

I can go upto the redline in 1st/2nd gear etc and the turbo timer only ever reaches 1.17/1.18 and doesnt beep or flash red.

Any ideas?

turbo timer ?????????????????????

or

boost controller ?

my boost controller is set so if i over boost it bleeps and flashes red
so,i took it out,lol.

That'll be the "over boost warning" on your turbo timer.

It is user settable (<- is that English?)/adjustable so you should be able to set it at whatever you like.

Naturally, with it warning you about blowing your motor, perhaps finding out a sensible boost level to have it set to trip at would be a good idea. I reckon no warning and your motor or gaskets blowing would likely cause more tears than a few beeps

HTH

The guy who previously had the car obviously set the 'over boost warning' on the turbo timer. It was RR'd at 1.2bar so i don't want to set it any higher.

But why is it beeping at me doing 80mph-100mph in 5th gear, when previously it hasn't? As i said im reluctant to drive it when its doing so so at the moment, in effect, my car is limited to <100mph

Is this happening to a standard car?

My 2003 UK WRX appears to sound its horn at 115mph which scared the **** out of me because I thought something was about to crash into me. I just pressumed it was a speed warning, is it something more sinister??

Regards,

Roger

Craig W

Anyone?

Brun

Cold weather may be causing a smidge extra boost which results in the overboost warning. Set the warning a touch higher
What method has been used to increse the boost?

Craig W

I haven't increased the boost? I haven't touched anything.

Thanks for your help.

afaik standard boost on your car should be around 1 bar, but with a decat and filter around 1.1bar, or at least thats what it was on my old MY00 uk.

How has the car clicked 269Bhp? It's either had a few £ spent on mods or the RR was way out

Craig W

Sorry i thought you meant what have i personally done to alter the boost.

The car has a Ninja zorst, de-cat, downpipe, filter, TEK2 ECU off the top of my head.

Brun

In which case i really do think it might be the weather. Do you have a knocklink? If not - i would get one and adjust the boost warning

Craig W

Excuse my lack of knowledge, lol, but what's a knocklink?
My turbo timer is a Blitz one.

I went out for a drive earlier to see if it was still doing and yep, in 5th gear between 80-100mph it bleeps and flashes red. It could be the weather, but ive been out on far colder days with no problems.

It's not bothering me too much, as i don't travel at high speeds often, i prefer to use the power accelerating through the gears etc... but... it's just worrying me that something is wrong with the car.

Many thanks again for your help

my mates my00 hit 267bhp or simmiler with filter, exhaust and dawse device on a td04

its not that big a deal IMO, from memory his was running 1.2bar as well

Craig W

Did he experience the same boost problems as me?

stevie boy

when it beeps and flashes red what is the display (pressuming its in the boost mode) reading? if you scrole through the modes until you find the peak boost recorded, are they way above your 1.2bar preset? either reset the peak boost reading or watch the readout whilst testing what the boost reaches in 4th gear, chances are it'll be a couple units (0.01bar) lower than in 5th - therfore nowt to worry about. as previously stated if you don't want it beeping at you just slightly up the overboost warn limit. in my old MY00 uk i would get around 0.1bar differance with differant weather / temps, chances are your dealing with a couple of 0.01bar

Craig W

If i floor it in 4th it reaches around 1.17/1.18.
If i floor it in 5th it reaches between 1.20/1.24

It beeps/flashes red as soon as it reaches 1.20, so i guess that's the limit.

I could have sworn mine did this to me the other day but it's never done that before when I've hit the Jap limiter @ 112MPH

stevie boy

the turbo timer is not part of the standard car, its an add on. when it beeps and flashes its not the car telling you that the world is going to end, its the turbo timer telling you that a preset value on the tt has been reached. if you set the warn limit to 0.60 bar it would be going off all the time but it doesn't mean you've gotta stop. scrole through the mode on the tt until you get to the warn preset (currently al 1.20 bar) (although afaik they read a in a jap unit simelar to bar but slightly less, like bhp/ps) and adjust it to 1.26.

chances are it'll be due to the cooler weather but have you changed/cleaned the air filter or done something that'll alter the breathing of the engine?

AFAIK the TEK2 has a target boost of 16.5psi (1.12bar) which it should achieve if you floor the throttle at 3500rpm in 5th. It shouldn't really peak at much more than that although I would think it would in the cold/rain, maybe 1.2?. You really need to check the peak as someone said above - if it is hitting, say, 1.3bar (mine was a few weeks ago with similar setup), then something needs doing, ie you need to see a man with a rolling road who will probably open the restrictor out a tad (0.05mm) (assuming everything else is OK and you have done the obvious like cleaning the boost controller etc).

Mine will peak at 1.4bar in warm weather if i'm lucky, but can hit 1.5 if the weather is cold

Craig W

Many thanks for the help people, i'll take into consideration what has been said. It's due to be serviced on Saturday and i'll take it to a RR in the near future.
