I already have a vacuum gauge installed in my corolla. I had it since the end of my acetone tests and before I had my Auto-LPG kit installed. So its been many years na.

I just started this thread just to "spread the knowledge".

question, we have a honda city AT with FC reading for the last 10 seconds, i use that to learn how to step on the gas. now we have a new vios AT but has no FC reading. I got 2 question.

1. The vios is only 2 days old, would installing this to the intake manifold void the warranty?

2. What I learn (how to step on the gas) from our honda with FC reading can be applied to vios and will result on better fc? Or different car = different behavior?

Knowing Toyota, if they find your modification, they can void the warranty but generally they will hardly notice an extra vacuum tube tapped into the engine's intake manifold. Just try to find an unused port on the intake manifold before resorting to using a "T" fitting to tap into an existing vacuum line.

Example is my ASX. It was only a month old and I had a UNICHIP installed. No one from Mitsu really notices it.

BUT if something does go wrong with your engine (something very remote from happening with a new car), best to disconnect and hide the vacuum tube (to the gauge) before having the engine checked.

As for learning how to step on the gas based on the vacuum gauge vs the fuel economy meter, it should be the same. In fact, the vacuum gauge would give you a faster feedback.

extra unleaded para mak tipid sa gas kung de gasolina oto at dipende din kung ganu na katanda ang isang sasakyan, pero kung mga 2013-2014 model na sasakyan yan sigurado matipid pa mga yaan.
