VEMS using fuel pressure as a sensor input
« on: July 24, 2009, 09:52:30 pm »
Looking at the skyline were fitting vems too.
Noted that theres an electronic fuel pressure sensor for a gauge.
Wondered if it could be used by VEMS to detect a drop in pressure and compensate to a degree?
Or if theres a catastrophic drop, to cut power big time! ???

That will need a firmware upgrade where one of the analog channels would be usable for compensation.
It´s a good idea, but so many cars in the world do not rely on this.,

I was thinking about it for my AE86 when the time comes.
Its a 35litre tank or thereabouts so running low on juice doesnt take long.
And Im concious of low pressure in a high comperssion NA lump at 9500rpm :D

I think a stable 1.1.xx release would be more preferable though.

What´s not stable?

I´ve installed 1.1.44 on plenty of cars all running without any issues.

Is that a final release?
I didnt think there was a stable release since 1.0.73?

On the megatune page in the Wiki it´s the latest relase. So I´d consider that stable.

I have not had one problem with it running megatune.
