i dont think im working this out right!! 2420 mbar cannot be 35psi, how would you work out how much psi you are running from mbar???  :huh:

i think a std gti runs about 9psi.

My Vagcom cable should be here next week :)

I bought it direct from RossTech, but had it sent to a US address and then that person is bringing it to the UK next week :D
£198 for the full cable, not just the MicroCan one. They are £269 at the UK supplier.

Boost pressure gauges (like the one you have fitted I think) measure boost above atmospheric pressure as far as I know. So here's the math!:

1 atmosphere = 1013.2 mbar on a standard day.
1 mbar = 0.01451 psi

2420-1013=  1407 mbar x 0.01451 = 20.42 psi

What boost are you running joe?

Like Max said you have to take atmospheric pressure into account which is always around 1000 then convert into PSI - which gives you a rough idea to comapre to your boost gauge.

Max - I would be interested in those logs -if you could email them to me  :wink:  Will PM you email address.

Rob, yeh that would be interesting to see yours - is yours of standard flavour or Ed30 ?

Interesting... looks like I am loosing a couple of PSI throughout the range - which is something I have read about on vortex.

MAF readings anyone?

i dont think im working this out right!! 2420 mbar cannot be 35psi, how would you work out how much psi you are running from mbar???  :huh:

i think a std gti runs about 9psi.


Boost pressure gauges (like the one you have fitted I think) measure boost above atmospheric pressure as far as I know. So here's the math!:

1 atmosphere = 1013.2 mbar on a standard day.
1 mbar = 0.01451 psi

2420-1013=  1407 mbar x 0.01451 = 20.42 psi

What boost are you running joe?

right so 20.42 psi from a remapped ed30 sounds about right   :smiley:

im running 18psi from an "original  :wink: gti" so im chuffed with that. if i make 260 bhp il be a happy chappy  :smiley: as its plenty enough for a lad my age  :cool: :smiley:
