Boost stops at 1.4bar - N75?

[Majorcina]

I need to get 1 boost leak test kit to

[newsh]

Excuse me? I thought you told us that you did a boost leak test?

Yes, he came here and we did it together. But he wants to do it again to check after having done the injector seals. You fix one leak it always shows another one up

A quick boost leak test bung can be made from an empty baked bean tin and a tubeless tyre valve, then you just to be creative and find some objects the correct diameter for the other holes you need to block.

Newsh helped me out with that

Where can I get boost test kit, anyone knows?

List of things I've tried.

• Boost test (leaks fixed)
• Checked all clips
• Checked N75
• Done output test

Good to hear that yours has been sorted out

...and by the looks of it, mine has too. 4th gear WOT ticked to 0.8 bar. As i finish work quite late, will go home on 50mph road anf see what I can squeeze outta it.

Just got back from VRS and I had a split hose which was brand new 1 month ago, leaks occur randomly and whenever they feel like it, also replaced injector seals, spark plugs, which are not even a year old with about 6k on them, and a small vacuum pipe on the fuel reg. Good news is she is now flying, happy days

I wouldn't be too fussy about getting it set absolutely bang on; it may just make the car think you're driving around slightly below sea level!
Glad the info is helpful, it certainly helped me a lot

So a new sensor should be set to 1200 ohms?

I really hope it will work

in fact here's the post that helped me sort my one out. its really easy to do if not a little fiddly getting the resistance correct (trial + error...lots of errors )

Wow. Did not know that. As I was reading, I was thinking, how did I miss this? Then I checked the date of the post. 2004. Okay, not crazy. I only showed up here in Feb. 2006.

Good info. Going to steal it and add it to my F96 post.

Thanks.

I got mine down to 1150ohms, see if it works, if it does, will take my time to set it to just under 1200ohms

Wish me luck

[hunker7]

...on my way to do that

[mike74]

Not sure mate. It might still be worthwhile 'adjusting' it so resistance between 1+2 is LESS than 1200 ohms (just a smidge). I set mine to 1180 ohms and regained my missing 5psi boost.

Thanks buddy. I've checked the sensor itself

Across 1 and 2: 1290 ohm
Across 1 and 3: 2850 ohm
Across 2 and 3: 2400 ohm

That means the sensor itself is fine. But ECU isn't giving the right voltage to the sensor, is that it?
