Hey guys, well ive noticed a little change in my tegs performance over the past two weeks, its felt very aggressive rev friendly, an ive owned it for 3 years approx now. My question is when imported from japan it came with 2 dials in the pillar pod,
one read oil pressure
the second im unsure on the term, think its to do with the inlet manifold pressure as it reads from -1 or -2 to 0 and when i put my foot down in any gear the needle goes round to 0 then i let go an drops to a certain -1.2 etcetc.

my query is i have never noticed this before and wanted to know is it telling me theres a leak somewhere if when driving i hold a speed say in third gear till the revs go round before vtec mid range (not speeding jus hold a speed to roughly when feel i should change gear) the needle goes round to say close to 0 as usal but...... it seems to go back down when holding that medium rpm.
It only seems to happenin the lower gear i.e. 2nd and third if hold the speed till car needs gear changed or hit vtec.

I am sorry an apologise again for such a confusing bloody thread,

thanks guys for any advice, ive just never noticed it do that before...

it does have a twinloop/decat fitted/mugen intake
 
Inlet manifold pressure.

Somewhat pointless on a NA car.

Sounds like it's working fine.
 
Yeah as Kosy said , it sound like a vacuum gauge.

When you a full throttle you will draw a larger vacuum and when you change gear the butterfly closes on the throttle body when you come off the accelerator. This draws in a minimal vacuum.

The more throttle with more vacuum on a NA engine :nice:

Otherway round, full throttle goes to atmospheric, throttle closed pulls a massive vacuum. :nice:
 
Lol my bad to used to watch a boost gauge if i can use that as an excuse :lol:
