Someone to flash my ECU

[junior]

Dont have a boost gauge but will be checking it all tomorrow.

I sent you a PM with a link that might help, but yeah like the others have said, I'd be checking the mechanicals before flashing it to solve a mechanical problem.... Once you have all the mechanicals correct then a flash can get you further....

Thanks again everyone, I will let you know how I get on.

Hi all, fitted a new BOV today and noticed the vacuum line attached to it appeared to be split at the top so with a bit of luck I may have fixed the issue

Just removed the ICE leads and checked the ohms and they read 1425/1765/1826. Can anyone tell me if this is the correct reading.

Needs to be a gauge with vac and boost, when at idle vac should be around -20 (someone else might know the exact number), if it's less then this then there is a leak somewhere. Small leaks can make a big difference.

Just curious, -20 bar? Kpa? My EBC reads i think about (-) 500 Mm/Hg at idle... Just wondering if that sounds normal etc.

-20 psi

 

[ed84]

-20 psi

ah of course. So 500MmHg is about 10 Ppsi..

spraying engine start (ether) around intercooler joins is a good way to test, the idle will pick up momentarily if there is a leak. also check your intercooler for damage

 

[TME_Steve]

-10psi, -20 isn't possible....

-10psi, -20 isn't possible....

My Boost gauge is showing -20psi during idle. Does this mean I have a leak?

Engines run vacuum at idle.. Turbos don't boost that low without throttle being open.
If the car idles smooth and even your car is running well.

Its -20inhg (inches of mercury) as vaccum is not measured in psi.
Although -20inhg roughly equates to 9.8psi worth of vaccum

Obviously atmospheric pressure is ~1bar / 14.7psi / +30inhg above perfect vaccum
So a perfect vaccum is ~-30inhg below atmospheric which is why most vaccum gauges (or vaccum ends of boost gauges) only read down to -30inhg

An average engine pulls around -15 to -20inhg with the throttle closed. Unless it has larger than stock camshafts

Thank you for the info.
