hadyn Posted May 4, 2007 Share Posted May 4, 2007 Bought myself an el cheapo autogauge boost gauge from egay. Unfortunately with the car switched off the gauge is reading -2 in vacuum pressure My car is totally stock and when Ive got both turbos online I get 0.6 bar with this iffy gauge. With this reading, I presume that Im really boosting at a normal 0.8 bar if its reading -2 negative pressure when switched off? Does anyone know if theres anyway I can recalibrate the gauge?

Paul Whiffin Posted May 4, 2007 Share Posted May 4, 2007 Complete shite I'm afraid! Bin it and get a decent make. Link to comment Share on other sites More sharing options...
hadyn Posted May 4, 2007 Author Share Posted May 4, 2007 Just for my info, if its reading -2 neg pressure with the engine switched off, we can presume its under-reading by 0.2 bar? Link to comment Share on other sites More sharing options...

hadyn Posted May 4, 2007 Author Share Posted May 4, 2007 Really disappointed with the guage tbh. I only bought one because my mate has one and its been perfect for him Link to comment Share on other sites More sharing options...
Ric Posted May 4, 2007 Share Posted May 4, 2007 i used too have one and that was ok too.. send it back? Link to comment Share on other sites More sharing options...
hadyn Posted May 4, 2007 Author Share Posted May 4, 2007 Really cant be arsed. Was only purchased to see if the car was boosting OK. I'll drop a decent brand in there in the near future. At least all the plumbing and wiring etc is now in place Link to comment Share on other sites More sharing options...
Hermit Posted May 4, 2007 Share Posted May 4, 2007 I bought one of those and had the same problem. Worse still, it wasn't even repeatable - when switched off it would settle randomly anywhere between -0.2 and 0.1!! Just binned it cos I wouldn't have trusted a replacement, even if it appeared to be working right. Bought a secondhand Apexi after that, which works great.

R Black Posted May 5, 2007 Share Posted May 5, 2007 Thats a shame, i have an Autogauge in mine, works fine though. Link to comment Share on other sites More sharing options...
hadyn Posted May 5, 2007 Author Share Posted May 5, 2007 Any ideas on how I could get the needle to sit at 0 bar when switched off? Link to comment Share on other sites More sharing options...
JamesC Posted May 5, 2007 Share Posted May 5, 2007 I've got one of these guages too. I put mine in the other week and its reading around 0.6 bar on full boost. I was getting ready to try the car in ?ttc? mode shortly to see if the actuators were working correctly. Think i'll get a new guage first Link to comment Share on other sites More sharing options...
MarkTheBoy Posted May 6, 2007 Share Posted May 6, 2007 ive got one and its fine, was dubious about buying a cheap one but it works perfectly well. I'll upgrade to something pukka one day but for the time being it'll do me Link to comment Share on other sites More sharing options...

hadyn Posted May 6, 2007 Author Share Posted May 6, 2007 Looks nice Mark. You can see the difference in readings between our two gauges on idle Link to comment Share on other sites More sharing options...
Bob Posted May 6, 2007 Share Posted May 6, 2007 If it's not zeroing properly, then there is no knowing what the actual readings are representing. Bin it. Link to comment Share on other sites More sharing options...
