Duffman Posted October 3, 2008 Share Posted October 3, 2008 Wired in my greddy boost gauge today and it aint giving a reading. All wired in correctly. Gauge has warning and memory button not sure what thses do and how to use them...could anyone advise? The gauge needle moves when i turn on the ignition but it goes up just below 0 and stays there...no reading at all Does anyone have one of thses gauges who can advise how to use 'memory' button & 'warning'. Also if anyone has any ideas as to how it aint giving a reading Cheers Quote Link to comment Share on other sites More sharing options...
SupraAyf Posted October 3, 2008 Share Posted October 3, 2008 Which source are you using to take your boost reading from? Quote Link to comment Share on other sites More sharing options...
Ewen Posted October 3, 2008 Share Posted October 3, 2008 Could be an epic in the making, but then again, surely not.... Quote Link to comment Share on other sites More sharing options...
Robzki Posted October 3, 2008 Share Posted October 3, 2008 I have the same gauge, but not got round to fitting yet. may do it over the weekend. I'll let you know if it works or not Quote Link to comment Share on other sites More sharing options...

ivan Posted October 3, 2008 Share Posted October 3, 2008 (edited) I see you didn't take our earlier advice to take it to someone who knows then... OK - You should have got a small adjuster with the gauge - you use that to set the warning level using the lower of the two pegs on the front (press in and turn). I set mine to just over 1 bar. It'll light up if you exceed (or possibly hit?) that value boost. Pressing the memory button will flick the needle up to show the max boost you've hit previously. Saves you having to watch the needle to see what boost you're hitting on those spirited drives - you can check later. As for why your boost isn't registering, I suggest you describe in painstaking detail exactly what you've connected and where. Preferably with good pictures. Failing that, fick narse. Edit.

Konrad Posted October 4, 2008 Share Posted October 4, 2008 I had a feeling that someone forgot to connect boost pipe Quote Link to comment Share on other sites More sharing options...
ivan Posted October 4, 2008 Share Posted October 4, 2008 (edited) Or possibly connected it to the existing boost gauge and nowhere else judging by some of the previous threads by the OP. :Pics: Edited October 4, 2008 by ivan (see edit history) Quote Link to comment Share on other sites More sharing options...

If you haven't already found it, the manual is here: http://www.greddy.com/img/PHP/products/pdf/701.pdf Right here we go... Have fitted boost gauge in my air vent space and tapped all the wires into the radio harness Black ground (gauge) - black ground (radio) red 12v constant - yellow 12v memory white illumination - orange illumination orange 12v ignition - red 12v ignition Gauge is now lighting up and the needle moves i.e. when i turn warning knob(dont have tool do with fingers) it resets itself to where it originally was after about 5 seconds. But when I start the car and take it for a drive there is no movement at all on gauge...have attached pic of what gauge looks like showing where needle is. When I first connected the gauge the needle wasn't staying still(without and with the engine running)...it was bouncing between the second white line under the 0bar and at about the 1st white line above the 0 bar. This might be irrelevant but I'm gonna say everything. Have detailed in the other 2 pics where I have connected the t-piece i.e. took the turbo pressure sensor out the original 'y-piece' and inserted the 't-piece'. Then connecteed the extra 2" of hose I had cut from the T to the original Y. Check out the pics and let me know what you think Thanks Quote Link to comment Share on other sites More sharing options...
ivan Posted October 4, 2008 Share Posted October 4, 2008 That looks suspiciously like the hose is only connected between the FPR and old boost sensor. Can anyone else confirm? Quote Link to comment Share on other sites More sharing options...

Duffman Posted October 6, 2008 Author Share Posted October 6, 2008 All I done insert the t-piece between the turbo pressure sensor and the original 'y-piece' (using 2" of hose)so its still connected as it was but with the boost gauge attached Quote Link to comment Share on other sites More sharing options...

Duffman Posted October 6, 2008 Author Share Posted October 6, 2008 managed to get hold of another wire that goes from the grey box to the engine bay and a new sensor...changed all that and it works fine...looks like it was faulty cheers ivan Quote Link to comment Share on other sites More sharing options...
