A bit of advice needed if possible?

Been looking for a boost gauge 20psi max so I don't have half the gauge never being used. The only ones I can find are either £200 from the motorsport places or £15 off ebay!! Is there really that much difference as they can't be that complicated?

cheers

I had a Tim's boost gauge which only went up to 1.5 bar
Another one won't hurt  .....

What ecu are you using?
Do you have electronic boost control?
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

I'm on the PE Turbo kit that @Essex2Visuvesi built which is low boost standard ECU set up. I bought the car but since it's been sat in my unit untouched.
I recently bought a Dastek with boost control from Ivo but have been in France for a few weeks so it's still sat in the footwell of my hillclimb car and I'm not fitting it until I can book it in for mapping.
I want afr, boost and oil pressure gauges before I start fannying about with it as I really don't want to detonate it before i've had chance to play!
It was just a generic question regarding expensive and cheap boost gauges and the fact there are no moving parts so are they really that different?

You want digital.
In psi not BAR.
Most boost analogue gauges scale is too large for the low boost 1zz setups.

Ive had cheap ebay gauges and found them to be as accurate as more expensive ones from the like of PLX.

For example on my SP240 turbo both read 10psi mid range falling to 7psi ish redline.

Dont buy a PLX AFR gauge had nothing but trouble with mine.

cheers Scott, just what I was after!

I was looking at either ebay / Amazon digital or a Bosch 20psi analogue so i'll go digital.

I'm looking at AEM X-Series or Innovate AFR - i've got 2nd dibs on a new AEM one for £100 that a guy bought and never fitted so just hoping the first dibs guy backs out!!

cheers

I have the AEM X-gauge in my car, really slim design and uses the latest Bosch LSU4.9 sensor - was easy to fit as well.

For a boost gauge, I would only go with a mechanical one, with the electronic ones with the stepper motors, they can be thrown out by a bad earth.

Surely a bad earth can affect anything electrical

That's why you have separate earths. One (or more) are for sensors. If the earth is bad, the boost gauge being inaccurate is the least of your worries.
I'm sure all of us always use the correct earths  ;)  Right?   haha

I do like the AEM one. Unfortunately the guy turned up so back on the lookout.
Turbo gauge, most of the digital ones seem to be electrical apart from a really really crappy looking cheap one which has the pipe going straight into the back of the gauge which id sort of been avoiding!
I think i'll take my chances with the better looking slightly more expensive one and earth it correctly!!

Looking like H tune have a discount on the AEM gauge at the moment, £160 for the full kit if you can't find another.

I have had a racetech mechanical gauge in previous boosted cars, although I think it reads to 2.5bar so slightly more than what your boost level is like.

You could always fit a boost cow :D
