~36 in/Hg vacuum reading?

[isnms]

is this normal?
while on cruise control i have about 36-37 in/Hg vacuum.


if not, what should i be looking for?

edit: at idle it's at ~ 20 in/Hg

That's a lot of vacumm. Even under decelleration, I cannot get mine to go any lower than 25-26.

Either you have a screwed up gauge or your engine can suck in a cow..... :bigthumb:

20 sounds right for idle. But 37 during light cruising is A LOT of vacuum. Max I get on decel is around 30, and normally cruise at 15-20

i usually idle around 20 and most i ever get is 25

What planet are you on? A lot of "vacuum" is right. It's not possible anywhere on Earth to have less than 29.92 in/hg and even that has never been achieved. I doubt it'd even be achievable in space.

^Thanks. I didn't know that.
I must have some sort of calibration issue or a defective sensor.
weird, it's fine at idle ~20 in/hg

ok, it appears to be an issue with my pda logger.
i took two logs this morning. first with the laptop then with the pda. the laptop did not have the spikes to 36in/Hg like the pda did.
i have written both digital tuning,inc. and zeitronix to see where the issue lies.

lol

perfect vacuum in space is 29.92 in/hg lol guy stating that on earth it hasn't been achieved is correct.

Fixed
I had a corrupt viewer app and it distorted the data as it displayed from my log.

Too bad, that would have been some huge bragging rights for the supra:biglaugh:
