boost meter not working

[N3T]

this always happen when i leave the car in the hot day (lunch time). the needle just sticks to 0. after driving about 5 minutes, then it just working fine.. is this normal? using apexi EL..

not normal. 0 is atmosphere pressure, typically before you start the engine. Idling will be less than zero.

try to swap you boost meter with your fren la bro,if ok,then something wrong wif your engine.

where u conected to?

it hapen recently or since u instal the meter?

check the hose at intake manifold, see got suction o not...maybe conect to the wrong place or faulty meter

sifoos... in the morning or whenever it is cold ambient, the meter is fine. idling is -0.5 (aircond on) or -0.7 (aircond off). the meter just stuck to 0 in the hot day whether idling or w.o.t.. it just like the meter is dead.. but after driving for a few minutes, it will operate as usual.. i noticed this since day one..

dun jump into conclusion 1st, get another meter n test 1st...tat the best way

i think it's the rubber hose. when i goyang-goyang the hose behind the meter, the needle jumped to negative (normal reading). that hose maybe 'kembang' while hot. maybe need to change to durable one such as silicone hose?
